Description

Technical Field

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

[0002] With the development of technology, people have higher and higher requirements for the reliability of electronic devices. In order to ensure that the electronic devices can maintain a stable structure during use, it is necessary to improve the bonding strength between the screen and the shell.

[0003] In the related art, the bonding strength between the screen and the shell is improved by increasing the bonding area between the screen and the shell.

[0004] However, during the glue erasing process, the screen will shake, thus affecting the improvement of bonding strength. Utility Model Content

[0005] The embodiments of the present application provide a housing and an electronic device, which are used to solve the problem of screen shaking when erasing glue in the related art.

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

[0007] In the first aspect, an embodiment of the present application provides a shell, including a middle plate portion and a side frame portion arranged at the edge of the middle plate portion, the middle plate portion and the side frame portion form a receiving groove for receiving the screen, the side frame portion is provided with a bearing surface facing away from the middle plate portion and a limiting surface facing the receiving groove, the bearing surface is used to bond a light-transmitting cover plate of the screen, the limiting surface is located on the side of the bearing surface away from the middle plate portion, the end of the limiting surface away from the middle plate portion is the first end, the end of the limiting surface facing the middle plate portion is the second end, and from the first end to the second end, the limiting surface gradually extends toward the central axis of the receiving groove.

[0008] The shell provided in the embodiment of the present application has a limiting surface that gradually extends toward the central axis of the accommodating groove from the first end to the second end after the screen is accommodated in the accommodating groove, that is, the gap width gradually decreases from top to bottom, so that the limiting surface can limit the bottom of the transparent cover plate in the horizontal direction, and the bearing surface is bonded to the transparent cover plate to limit the transparent cover plate in the vertical direction, thereby reducing the movement of the screen when erasing the glue and playing a role of pre-fixing.

[0009] In addition, when the light-transmitting cover plate is placed in the receiving groove, the limiting surface can also play a certain guiding role in the assembly of the screen, so that the screen can be smoothly placed in the receiving groove along the limiting surface.

[0010] Therefore, the present application can solve the problem of screen shaking when erasing glue in the related art.

[0011] In some possible implementations of the first aspect, the limiting surface is a curved surface. Alternatively, the limiting surface is a flat surface.

[0012] In this way, by limiting the shape of the limiting surface, the screen has a certain degree of flexibility during assembly, making it easier for the screen to find the correct assembly position, thereby facilitating guidance and assembly.

[0013] In some possible implementations of the first aspect, the arc surface is recessed away from the central axis of the accommodation groove, or the arc surface is protruding toward the central axis of the accommodation groove.

[0014] In this way, by setting the limiting surface as a convex arc surface and a concave arc surface, the guiding effect is better to a certain extent, and at the same time the friction and resistance during assembly can be reduced, thereby making the assembly smoother.

[0015] In some possible implementations of the first aspect, the limiting surface includes a plurality of limiting structural surfaces, and the plurality of limiting structural surfaces are arranged at intervals along a peripheral wall of the accommodating groove.

[0016] In this way, by setting up multiple limiting structural surfaces, it is possible to ensure that the screen has a more accurate position and direction during assembly, thereby improving the accuracy and efficiency of limiting and assembly, reducing the adjustment and correction time during the assembly process, and greatly reducing the amount of screen movement during wiping.

[0017] In addition, compared with setting a limited surface around the accommodating groove, the bonding area between the transparent cover plate and the shell is relatively large, that is, there is more glue between the transparent cover plate and the shell, which has a certain buffering effect when the electronic device is subjected to external force, and can reduce damage to the electronic device.

[0018] In some possible implementations of the first aspect, the side frame portion includes a body and a stopper. The bearing surface is formed on the body, the body also includes a longitudinal surface, the longitudinal surface is located on a side of the bearing surface away from the central axis and intersects with the bearing surface, the stopper is arranged on a side of the longitudinal surface facing the central axis and is located on the side where the bearing surface is located, the stopper is connected to the longitudinal surface, and a surface of the stopper facing away from the longitudinal surface forms the stopper surface.

[0019] In this way, by setting a limiter on the main body, the limiter surface on the limiter can limit the transparent cover in the horizontal direction, thereby reducing the movement of the screen when erasing the glue, and playing a role of pre-fixing. The main body and the limiter are set as a separate structure, and the screen can be limited with higher precision by adjusting and replacing the limiter, thereby improving the limiting effect. In addition, the overall weight of the side frame can be reduced by adjusting the material of the limiter, which is conducive to the lightweight design of the electronic device.

[0020] In some possible implementations of the first aspect, the side frame portion is further provided with an exposed surface, the exposed surface is located on the side of the limiting surface away from the central axis, and the exposed surface is located on the side of the limiting surface away from the bearing surface, and the exposed surface extends in a direction away from the central axis. The side frame portion is further provided with a rubber-conducting surface located between the limiting surface and the exposed surface, the end of the rubber-conducting surface facing the limiting surface is the third end, and the end of the rubber-conducting surface facing the exposed surface is the fourth end. The fourth end is flush with the end of the exposed surface facing the fourth end, and the third end is lower than the fourth end. Alternatively, the third end is flush with the fourth end.

[0021] In this way, by setting the fourth end of the adhesive guiding surface to be flush with the end of the exposed surface facing the fourth end, when the screen is placed in the accommodating groove, the gap between the side of the transparent cover plate facing the limiting surface and the limiting surface is smaller, and the limiting accuracy and limiting effect are better.

[0022] In addition, the third end of the adhesive conductive surface is set lower than the fourth end, so that the adhesive conductive surface has a certain height difference, so that after the adhesive is dispensed on the adhesive conductive surface, it is conducive to the smooth flow of glue into the gap, thereby facilitating the bonding effect between the transparent cover plate and the shell.

[0023] In some possible implementations of the first aspect, the third end is lower than the fourth end, and the rubber conducting surface is a curved surface, or the rubber conducting surface is a flat surface.

[0024] In this way, setting the glue-conducting surface as a curved surface or a flat surface can optimize the flow path of the glue, making the glue smoother during filling and easier to fill into every corner of the contact surface. At the same time, it reduces the generation of bubbles, which is beneficial to improving the uniformity and bonding strength of the glue, thereby helping to improve the bonding effect between the light-transmitting cover and the shell.

[0025] In addition, setting the adhesive-conducting surface as a curved surface or a flat surface can prevent interference between the screen and the shell during assembly, which is conducive to smooth assembly of the screen and the shell.

[0026] In some possible implementations of the first aspect, the side frame portion is further provided with an exposed surface, the exposed surface is located on a side of the limiting surface away from the central axis and away from the bearing surface, and the exposed surface extends in a direction away from the central axis, and the side frame portion is further provided with a rubber hanging surface located between the limiting surface and the exposed surface, and the end of the rubber hanging surface facing the limiting surface is the third end, and the end of the rubber hanging surface facing the exposed surface is the fourth end. The fourth end is lower than the end of the exposed surface facing the fourth end, the third end is flush with the fourth end, or the third end is higher than the fourth end, and the third end is lower than the end of the exposed surface facing the fourth end.

[0027] In this way, by setting the fourth end of the glue-hanging surface to be lower than the end of the exposed surface facing the fourth end, and setting the third end of the glue-hanging surface to be lower than the end of the exposed surface facing the fourth end, after dispensing glue on the glue-hanging surface, the glue can flow along the edge of the glue-hanging surface into the gap between the side of the light-transmitting cover plate facing the limiting surface and the limiting surface, and when the outer surface of the light-transmitting cover plate away from the bearing surface is higher than the glue-hanging surface, the glue can completely cover the glue-hanging surface, which is beneficial to increase the bonding area between the light-transmitting cover plate and the shell and to ensure the appearance of the electronic device.

[0028] In some possible implementations of the first aspect, the adhesive hanging surface is a curved surface, or the adhesive hanging surface is a flat surface.

[0029] In this way, by setting the glue hanging surface as a curved surface, the bonding area between the light-transmitting cover plate and the shell can be increased, which is beneficial to improving the stability and strength of the bonding; by setting the glue hanging surface as a flat surface, it is easy to process and the production cost can be reduced.

[0030] In a second aspect, an embodiment of the present application provides an electronic device, including a screen, a housing, and an adhesive layer. The screen includes a light-transmitting cover plate, the light-transmitting cover plate includes an edge portion, the edge portion includes a connected back and side surface, the bearing surface is opposite to the back surface, the limiting surface is opposite to the side surface, the adhesive layer is arranged between the bearing surface and the back surface and between the limiting surface and the side surface, and the light-transmitting cover plate is connected to the housing through the adhesive layer.

[0031] In this way, by setting a limiting surface on the shell, after the screen is accommodated in the accommodating groove, the limiting surface can limit the bottom of the edge part in the horizontal direction, and the part of the glue layer between the bearing surface and the back surface can limit the edge part in the vertical direction, thereby reducing the movement of the screen when the glue is wiped, and playing a role of pre-fixation. At the same time, compared with the vertical limiting surface, the gap between the side and the limiting surface can be reduced, making it easier for the glue layer to fill the gap, which is conducive to increasing the coverage area and bonding effect of the glue layer, and thus improving the reliability of the electronic device.

[0032] In a third aspect, an embodiment of the present application provides an electronic device, including a screen, a housing, and an adhesive layer. The screen includes a light-transmitting cover plate, the light-transmitting cover plate includes an edge portion, the edge portion includes a connected back and side surface, the bearing surface is opposite to the back surface, the limiting surface is opposite to the side surface, the adhesive layer is arranged between the bearing surface and the back surface and between the limiting surface and the side surface, and the light-transmitting cover plate is connected to the housing through the adhesive layer.

[0033] In this way, by setting a limiting surface on the shell, after the screen is accommodated in the accommodating groove, the limiting surface can limit the bottom of the edge part in the horizontal direction, and the part of the glue layer between the bearing surface and the back surface can limit the edge part in the vertical direction, thereby reducing the movement of the screen when the glue is wiped, and playing a role of pre-fixation. At the same time, compared with the vertical limiting surface, the gap between the side and the limiting surface can be reduced, making it easier for the glue layer to fill the gap, which is conducive to increasing the coverage area and bonding effect of the glue layer, and thus improving the reliability of the electronic device.

[0034] In some possible implementations of the third aspect, the adhesive layer covers part of the surface of the adhesive conductive surface. Alternatively, the surface of the adhesive layer exposed from the adhesive conductive surface is flush with the third end. Alternatively, the surface of the adhesive layer exposed from the adhesive conductive surface is lower than the third end.

[0035] In this way, the gap between the limiting surface and the side surface is smaller, making it easier for the adhesive layer to fill the gap, thereby facilitating improving the bonding effect between the light-transmitting cover plate and the housing, and further improving the reliability of the electronic device.

[0036] In a fourth aspect, an embodiment of the present application provides an electronic device, including a screen, a housing, and an adhesive layer. The screen includes a light-transmitting cover plate, the light-transmitting cover plate includes an edge portion, the edge portion includes a connected back and side surface, the bearing surface is opposite to the back surface, the limiting surface is opposite to the side surface, the adhesive layer is arranged between the bearing surface and the back surface and between the limiting surface and the side surface, and the light-transmitting cover plate is connected to the housing through the adhesive layer.

[0037] In this way, by setting a limiting surface on the shell, after the screen is accommodated in the accommodating groove, the limiting surface can limit the bottom of the edge part in the horizontal direction, and the part of the glue layer between the bearing surface and the back surface can limit the edge part in the vertical direction, thereby reducing the movement of the screen when the glue is wiped, and playing a role of pre-fixation. At the same time, compared with the vertical limiting surface, the gap between the side and the limiting surface can be reduced, making it easier for the glue layer to fill the gap, which is conducive to increasing the coverage area and bonding effect of the glue layer, and thus improving the reliability of the electronic device.

[0038] In some possible implementations of the fourth aspect, the adhesive layer covers the adhesive hanging surface.

[0039] In this way, by completely covering the adhesive surface with the adhesive layer, it is helpful to increase the bonding area between the light-transmitting cover plate and the housing and to ensure the aesthetic appearance of the electronic device. BRIEF DESCRIPTION OF THE DRAWINGS

The frame 22 is located between the back cover 21 and the screen 1 and is arranged along the edge of the back cover 21 and the edge of the screen 1. The frame 22 is fixed to the back cover 21.

A receiving cavity (not shown in the figure) is provided in the back shell 2, and the receiving cavity is used to accommodate electronic components.

[0078] In some embodiments, the accommodating cavity is located between the screen 1 and the back cover 21 .

[0079] The back shell 2 is also provided with a receiving groove ( Figure 2 The receiving groove is used to receive the screen. In some embodiments, the receiving groove can be formed by the frame 22 and the back cover 21.

[0080] In some embodiments, please refer to Figure 2 The back shell 2 may further include a middle plate 23. The middle plate 23 is fixed to the inner surface of the frame 22. For example, the middle plate 23 may be fixed to the frame 22 by welding. The middle plate 23 may also be an integrally formed structure with the frame 22. The middle plate 23 is used as a structural "skeleton" of the electronic device 100, and is used to support and fix the electronic components in the electronic device 100.

[0082] The circuit board assembly 3 is accommodated in the accommodating cavity. In some embodiments, the circuit board assembly 3 can be fixed to the middle plate 23. In other embodiments, when the electronic device 100 does not include the middle plate 23, the circuit board assembly 3 can also be fixed to the back cover 21 or the frame 22.

[0083] In some embodiments, see Figure 3 , Figure 3 for Figure 1 The electronic device 100 is shown in a cross-sectional view taken along the AA line. Figure 3 In the embodiment, the circuit board assembly 3 may be composed of a main board 301 and a sub-board 302 , and the electronic device 100 further includes a battery 4 for providing power to the main board 301 and other components to ensure the normal operation of the electronic device 100 .

[0086] In some embodiments, the light-transmitting cover plate 11 is bonded to the edge of the front housing 24 via its edge portion so that the screen 1 is bonded to the front housing 24 .

[0087] See also Figure 4The edge of the light-transmitting cover plate 11 includes a back surface 111 and a side surface 112, wherein the back surface 111 is the surface facing away from the light-transmitting cover plate 11 when the user normally uses the electronic device 100.

The back surface 111 is opposite to the step surface 3241, and the side surface 112 is opposite to the longitudinal surface 3242.

[0088] Related technologies, continue to refer to Figure 4 , by gluing the back surface 111 and the step surface 3241 together, the light-transmitting cover plate 11 is bonded to the front shell 24. However, in some cases, the bonding area between the back surface 111 and the step surface 3241 is limited, and the screen 1 and the back shell 2 are prone to fall off. In order to solve this problem, in the related art, the bonding strength is improved by increasing the bonding area between the screen 1 and the back shell 2, that is, liquid glue is filled between the back surface 111 and the step surface 3241 and between the side surface 112 and the longitudinal surface 3242.

[0089] Glue is dispensed between the side surface 112 and the longitudinal surface 3242 , and then the glue needs to be wiped off. During the process of wiping the glue, the screen 1 may shake due to the large gap between the side surface 112 and the longitudinal surface 3242 .

[0090] On this basis, the present application provides a shell, which, by setting a limiting surface on the shell, can ensure the bonding area between the light-transmitting cover plate and the shell, while also limiting the light-transmitting cover plate, thereby solving the problem of screen shaking when erasing glue.

[0093] The following embodiments are described by taking the example that the housing 30 includes the front housing 24 , the middle plate portion 31 is the middle plate portion of the front housing 24 , and the side frame portion 32 is the edge portion of the front housing 24 .

[0095] Exemplarily, the middle plate portion 31 can be integrally formed with the side frame portion 32, which is beneficial to improve the structural strength and rigidity of the housing 30. Of course, the middle plate portion 31 can also be a separate structure from the side frame portion 32, and the middle plate portion 31 can be fixedly connected to the side frame portion 32 by threaded connection, welding, etc.

[0096] Continue reading Figure 5 The side frame portion 32 is provided with a bearing surface 321 facing away from the middle plate portion 31 and a limiting surface 322 facing the accommodating groove 33 . The bearing surface 321 is used to bond the light-transmitting cover plate 11 of the screen 1 , and the limiting surface 322 is located on the side of the bearing surface 321 away from the middle plate portion 31 .

[0097] The bearing surface 321 may be connected to the limiting surface 322, that is, one end of the bearing surface 321 facing the limiting surface 322 is connected to one end of the limiting surface 322 facing the bearing surface 321. Of course, the bearing surface 321 may also be not connected to the limiting surface 322, that is, there is a certain distance between one end of the bearing surface 321 facing the limiting surface 322 and one end of the limiting surface 322 facing the bearing surface 321.

[0098] Continue reading Figure 5 In some embodiments, the end of the limiting surface 322 away from the middle plate portion 31 is the first end, and the end of the limiting surface 322 facing the middle plate portion 31 is the second end, that is, the first end is located above the second end. From the first end to the second end, the limiting surface 322 gradually extends toward the central axis of the accommodating groove 33.

[0099] After the screen 1 is accommodated in the accommodating groove 33, the bearing surface 321 is bonded to the back surface 111 of the transparent cover plate 11 to limit the transparent cover plate 11 in the vertical direction. There is a gap between the side surface 112 of the transparent cover plate 11 and the limiting surface 322. From the first end to the second end, the limiting surface 322 gradually extends toward the central axis of the accommodating groove 33, that is, the width of the gap gradually decreases from top to bottom, so that the limiting surface 322 can limit the bottom of the transparent cover plate 11 in the horizontal direction, thereby reducing the movement of the transparent cover plate 11 when erasing the glue, and playing a role of pre-fixing.

[0100] In addition, the limiting surface 322 is formed on the housing 30 , which can ensure that no displacement occurs during the assembly process, and is beneficial to improving the limiting accuracy and limiting effect of the limiting surface 322 on the screen 1 in the horizontal direction.

[0101] In addition, the limiting surface 322 can also play a certain guiding role in the assembly of the screen 1, so that the screen 1 can be smoothly accommodated in the accommodating groove 33 along the limiting surface 322.

[0102] Therefore, the present application can solve the problem of screen shaking when erasing glue in the related art.

[0103] There are many situations in which the bonding strength is improved by increasing the bonding area between the screen 1 and the back shell 2 as mentioned above. For example, in order to increase the screen-to-body ratio of the electronic device 100, the screen 1 needs to be designed with a narrow frame, so that the bonding area between the back surface 111 and the step surface 3241 is reduced. Therefore, it is necessary to fill liquid glue between the side surface 112 and the longitudinal surface 3242 to increase the bonding area to ensure the bonding reliability of the screen 1 and the back shell 2.

[0104] Continue reading Figure 4 , and combined with Figure 3 The back side 111 of the transparent cover plate 11 is coated with black ink (not shown in the figure), so that the edge of the transparent cover plate 11 is displayed as a black border from the front side, and the front side is the surface facing the transparent cover plate 11 when the user normally uses the electronic device 100. The smaller the width of the black border, the higher the screen-to-body ratio of the electronic device 100, and the better the visual effect.

[0105] When the width L1 of the black border is 0.55 mm, the bonding strength between the light-transmitting cover plate 11 and the front shell 24 can be ensured by bonding the back surface 111 to the step surface 3241 , and the width of 0.55 mm has reached the limit of satisfying the debonding reliability test of the light-transmitting cover plate 11 .

[0106] See also Figure 6 When the width of the black border is set to be less than 0.55 mm, for example, when the width L2 of the black border is set to 0.45 mm, the bonding area between the back surface 111 and the step surface 3241 in the horizontal direction is reduced. In order to ensure the bonding strength between the light-transmitting cover plate 11 and the front shell 24, it is necessary to perform glue dispensing, glue pouring, etc. between the side surface 112 and the longitudinal surface 3242 to bond the side surface 112 to the longitudinal surface 3242, thereby increasing the bonding area between the light-transmitting cover plate 11 and the front shell 24, and ensuring that the black border width is less than 0.55 mm and can still meet the reliability test of the light-transmitting cover plate 11.

[0107] Continue reading Figure 6 By adding adhesive backing 50 between the back of the display screen 12 and the middle plate of the front shell 24, the screen 1 is pulled to play a pre-fixing role when the glue is wiped, so as to prevent the screen 1 from moving and causing the glue to delaminate and lose the adhesive force, thereby ensuring the adhesive strength between the transparent cover plate 11 and the front shell 24. However, during the process of disassembling, repairing or replacing the screen 1, the screen 1 may be delaminated internally, thereby reducing the reliability of the screen 1.

[0108] The present application limits the screen 1 by the limiting surface 322, and there is no need to set the adhesive backing 50 to pre-fix the screen 1 and the shell 30, which can solve the problem of internal stratification of the screen 1 that may occur during the disassembly, maintenance or replacement of the screen 1 in the above embodiment.

[0109] Continue reading Figure 5 In some embodiments, the limiting surface 322 is a curved surface.

[0110] The arc surface can be used to limit structures of various shapes, so it can be applied to the light-transmitting cover plate 11 whose edge portion is in a shape other than the rectangular parallelepiped in the embodiment of the present application. In addition, the contact area of ​​the arc surface is relatively large, and it has a certain guiding effect, which can guide the light-transmitting cover plate 11 to move along the arc surface, so that the screen 1 is more stable during the movement of assembling with the shell 30, effectively reducing unnecessary swinging and shaking of the light-transmitting cover plate 11 during movement, and then smoothly assembling.

[0111] In addition, since the contact area of ​​the arc surface is large and the friction force is evenly distributed, the limit surface 322 has better wear resistance. That is, during the movement of the transparent cover plate 11, the limit surface 322 set as a arc surface can better resist friction and wear, thereby extending the service life of the shell 30.

[0112] In this way, by setting the limiting surface 322 as a curved surface, the screen 1 has a certain degree of flexibility during assembly, making it easier for the screen 1 to find the correct assembly position, thereby facilitating assembly. At the same time, the limiting surface 322 can better resist friction and wear, thereby extending the service life of the shell 30.

[0113] See also Figure 7 In some possible embodiments, the arc surface is recessed away from the central axis of the accommodating groove 33, that is, the limiting surface 322 is an arc surface convex to the right side. While ensuring that the transparent cover plate 11 can be smoothly accommodated in the accommodating groove 33 along the arc surface during movement, the bottom of the arc surface can also limit the bottom of the transparent cover plate 11, thereby reducing the movement of the transparent cover plate 11 when erasing the glue, and playing a role of pre-fixing.

[0114] In addition, while maintaining structural strength and rigidity, the curved surface is also beneficial for reducing the weight of the housing 30, thereby facilitating a lightweight and thin design of the electronic device.

[0115] Continue reading Figure 5 In some other possible embodiments, the arc surface protrudes toward the central axis of the receiving groove 33, that is, the limiting surface 322 is an arc surface protruding toward the left. Similarly, while ensuring that the light-transmitting cover plate 11 can be smoothly accommodated in the receiving groove 33 along the arc surface during movement, the bottom of the arc surface can also limit the bottom of the light-transmitting cover plate 11, reduce the movement of the light-transmitting cover plate 11 during rubbing, and play a role of pre-fixation.

[0116] In addition, the setting of the arc surface is also more conducive to reducing the gap between the side surface 112 of the transparent cover plate 11 and the limiting surface 322, thereby improving the limiting accuracy and limiting effect.

[0117] Therefore, by setting the limiting surface 322 as a convex arc surface and a concave arc surface, the guiding effect is better to a certain extent, and at the same time, the friction and resistance during assembly can be reduced, thereby making the assembly smoother.

[0118] See also Figure 8 In some embodiments, the limiting surface 322 is a plane. While ensuring the limiting effect and the guiding effect, the processing cost of the plane is low, which is conducive to reducing the production cost of the electronic device.

[0119] Of course, in addition to being configured as the aforementioned arc surface and plane, the limiting surface 322 may also be configured as other irregularly shaped curved surfaces, as long as the curved surface gradually extends toward the central axis of the accommodating groove 33 from the top to the bottom of the curved surface.

[0120] Exemplarily, the limiting surface 322 may also be composed of two arc surfaces, such as Fig. 9 As shown, the upper portion of the limiting surface 322 is an arc surface convex to the left, and the lower portion is an arc surface convex to the right. In this way, the trajectory of the limiting surface 322 is smoother, which is more conducive to the smooth assembly of the transparent cover plate 11.

[0121] See also Fig.10 In some other possible embodiments, the limiting surface 322 may be composed of a longitudinal plane 3222 located at the upper part and a limiting curved surface 3223 located at the lower part, wherein, from one end of the longitudinal plane 3222 away from the bearing surface 321 to one end of the longitudinal plane 3222 facing the bearing surface 321, the distance between the longitudinal plane 3222 and the central axis of the receiving groove 33 is the same, and from one end of the limiting curved surface 3223 away from the bearing surface 321 to one end of the limiting curved surface 3223 facing the bearing surface 321, the limiting curved surface 3223 gradually extends toward the central axis of the receiving groove 33. With such a configuration, the limiting surface 322 can also limit and guide the light-transmitting cover plate 11.

[0122] Exemplarily, the limiting curved surface 3223 may be Fig.10 The arc surface shown in the figure may also be a plane, which is not specifically limited in this embodiment.

[0123] See also Fig.11 In some embodiments, the limiting surface 322 includes a plurality of limiting structural surfaces 3221 , and the plurality of limiting structural surfaces 3221 are arranged at intervals along the peripheral wall of the accommodating groove 33 .

[0124] By setting multiple limiting structural surfaces 3221 at intervals, it can be ensured that the screen 1 has a more accurate position and direction during assembly, thereby improving the accuracy and efficiency of limiting and assembly, reducing the adjustment and correction time during the assembly process, and greatly reducing the movement of the screen 1 during erasing.

[0125] In addition, compared with setting a limited position surface 322 around the accommodating groove 33, the bonding area between the transparent cover plate 11 and the shell 30 is relatively large, that is, there is more glue between the transparent cover plate 11 and the shell 30, so that it has a certain buffering effect after the electronic device is subjected to external force, which can reduce the damage of the electronic device.

[0126] For example, the position and number of the limiting structure surface 3221 can be set as needed, and this embodiment does not specifically limit this. A plurality of limiting structure surfaces 3221 can be set at the four corners of the receiving groove 33, and the limiting structure surface 3221 can also be set at intervals between two adjacent corners.

[0127] It should be noted that when the limiting structural surfaces 3221 are provided at the four corners, appropriate curvatures need to be provided to ensure that the edge portion of the light-transmitting cover plate 11 can be smoothly assembled with the housing 30 .

[0128] See also Fig.12 In some embodiments, the side frame portion 32 includes a main body 323 and a limiting member 324, that is, the side frame portion 32 is a split structure.

[0129] Exemplarily, the material of the limiting member 324 may be metal, plastic, etc., and may be the same as or different from the material of the main body 323 .

[0130] Exemplarily, the body 323 may be fixedly connected to the limiting member 324 by means of threaded connection, adhesive connection, welding, or the like.

[0131] The bearing surface 321 is formed on the body 323 . The body 323 further includes a longitudinal surface 3242 . The longitudinal surface 3242 is located on a side of the bearing surface 321 away from the central axis and intersects with the bearing surface 321 . The longitudinal surface 3242 is disposed toward the receiving groove 33 .

[0132] Exemplarily, when the screen 1 is accommodated in the accommodating groove 33 , the gap width L3 between the side surface 112 of the light-transmitting cover plate 11 and the longitudinal surface 3242 is 0.1 mm.

[0133] The limiting member 324 is disposed on the side of the longitudinal surface 3242 facing the central axis and located on the side where the bearing surface 321 is located. The limiting member 324 is connected to the longitudinal surface 3242 , and the surface of the limiting member 324 facing away from the longitudinal surface 3242 forms the limiting surface 322 .

[0134] In this way, by setting the limiter 324 on the body 323, the limiter surface 322 on the limiter 324 can limit the transparent cover plate 11 in the horizontal direction, thereby reducing the movement of the screen 1 when erasing the glue, and playing a role of pre-fixing. The body 323 and the limiter 324 are set as a separate structure, and the screen 1 can be limited with higher precision by adjusting and replacing the limiter 324, thereby improving the limiting effect. In addition, the overall weight of the side frame 32 can be reduced by adjusting the material of the limiter 324, which is conducive to the lightweight design of the electronic device.

[0135] For example, the size of the stopper 324 can be set as needed, and along the direction of the gap width, the minimum size L4 of the stopper 324 is greater than or equal to 0.05 mm. Such a setting can ensure a gap with a smaller width between the side surface 112 of the transparent cover plate 11 and the stopper surface 322, thereby facilitating the improvement of the stopper accuracy and stopper effect.

[0136] It can be understood that when the color and material of the limiting member 324 are the same as those of the main body 323 , it is more conducive to the aesthetic appearance of the electronic device.

[0137] See also Fig.13 In some embodiments, the side frame portion 32 is further provided with an exposed surface 325 , and the exposed surface 325 is the surface of the side frame portion 32 that exposes the electronic device 100 .

[0138] The exposed surface 325 is located on the side of the limiting surface 322 away from the central axis, and the exposed surface 325 is located on the side of the limiting surface 322 away from the bearing surface 321, and extends in a direction away from the central axis. The exposed surface 325 can be a horizontal surface, of course, the exposed surface 325 can also be an inclined surface.

[0139] The side frame portion 32 is further provided with a glue guiding surface 326 located between the limiting surface 322 and the exposed surface 325 , and the glue guiding surface 326 is used to guide the glue to flow into the gap between the side surface 112 of the transparent cover plate 11 and the limiting surface 322 .

[0140] One end of the adhesive conductive surface 326 facing the limiting surface 322 is a third end, and one end of the adhesive conductive surface 326 facing the exposed surface 325 is a fourth end.

[0141] Continue reading Fig.13 In some embodiments, the fourth end is flush with an end of the exposed surface 325 facing the fourth end, and the third end is lower than the fourth end.

[0142] By setting the fourth end of the adhesive guiding surface 326 to be flush with the end of the exposed surface 325 facing the fourth end, when the screen 1 is accommodated in the accommodating groove 33, the gap between the side of the transparent cover plate 11 facing the limiting surface 322 and the limiting surface 322 is smaller, and the limiting accuracy and limiting effect are better.

[0143] In addition, the third end of the adhesive conductive surface 326 is set to be lower than the fourth end, so that the adhesive conductive surface 326 has a certain height difference, so that after glue is dispensed on the adhesive conductive surface 326, it is beneficial for the glue to flow smoothly along the adhesive conductive surface 326 into the gap, which is beneficial to improve the bonding effect between the transparent cover plate 11 and the shell 30.

[0144] In addition, the third end of the adhesive guiding surface 326 is set to be lower than the fourth end. During the assembly of the screen 1 and the shell 30, the connection between the adhesive guiding surface 326 and the limiting surface 322 will not interfere with the bottom of the transparent cover plate 11, which is conducive to the smooth assembly of the screen 1 and the shell 30.

[0145] See also Fig.14 In some embodiments, when the third end of the glue-conducting surface 326 is lower than the fourth end, the glue-conducting surface 326 can be set to a curved surface. The curved surface can optimize the flow path of the glue, making the glue flow more smoothly during filling and easier to fill into every corner of the contact surface. At the same time, it reduces the generation of bubbles, which is beneficial to improving the uniformity and bonding strength of the glue, thereby helping to improve the bonding effect between the transparent cover plate 11 and the shell 30.

[0146] Continue reading Fig.13 In some other embodiments, the glue guiding surface 326 can be set to a plane, which can guide the glue to flow smoothly into the gap and help reduce processing costs.

[0147] See also Fig.15 In some other embodiments, the third end of the adhesive conductive surface 326 is flush with the fourth end, so that the appearance of the housing 30 is neater.

[0148] It is understandable that the glue guiding surface 326 can also be set as a curved surface of other shapes, as long as it can guide the glue to flow smoothly into the gap. This embodiment does not make any specific limitation to this.

[0149] See also Fig.16 On the basis that the side frame portion 32 is provided with an exposed surface 325, the side frame portion 32 is further provided with a glue hanging surface 327 located between the limiting surface 322 and the exposed surface 325, and the glue hanging surface 327 is used for glue hanging.

[0150] The end of the glue-hanging surface 327 facing the limiting surface 322 is the third end, and the end of the glue-hanging surface 327 facing the exposed surface 325 is the fourth end.

[0151] Continue reading Fig.16 In some embodiments, the fourth end of the rubber hanging surface 327 is lower than the end of the exposed surface 325 facing the fourth end, and the third end of the rubber hanging surface 327 is flush with the fourth end.

[0152] After the glue is dispensed on the glue surface 327, the glue can flow along the edge of the glue surface 327 to the limiting surface 322, and finally fill the gap between the side 112 of the transparent cover 11 and the limiting surface 322, and when the end of the side 112 of the transparent cover 11 away from the back 111 is higher than the glue surface 327, the glue can completely cover the glue surface 327, which is beneficial to increase the bonding area between the transparent cover 11 and the shell 30, and is also beneficial to ensure the appearance of the electronic device.

[0153] See also Fig.17 In some other embodiments, the third end of the glue-hanging surface 327 is higher than the fourth end, and the third end is lower than the end of the exposed surface 325 facing the fourth end, that is, a glue-hanging groove 3271 is formed between the surface between the glue-hanging surface 327 and the exposed surface 325 and the glue-hanging surface 327. Similarly, after glue is dispensed on the glue-hanging surface 327, the glue first fills the glue-hanging groove 3271, and glue dispensing continues. The glue overflowing the glue-hanging groove 3271 can slowly flow along the edge of the glue-hanging surface 327 to the limiting surface 322, and finally fill the entire gap.

[0154] After the glue is applied, the glue completely covers the glue-hanging surface 327 , which is beneficial to increasing the bonding area between the light-transmitting cover plate 11 and the housing 30 , and is also beneficial to ensuring the aesthetic appearance of the electronic device.

[0155] Of course, see Fig.18 In some other possible embodiments, the third end of the glue surface 327 may also be set to be lower than the fourth end. When the end of the side surface 112 of the transparent cover plate 11 away from the back surface 111 is higher than the third end of the glue surface 327, the glue can still completely cover the glue surface 327, which is beneficial to increase the bonding area between the transparent cover plate 11 and the housing 30, and is also beneficial to ensure the appearance of the electronic device.

[0156] See also Fig.19 In some embodiments, the glue hanging surface 327 can be a curved surface.

[0157] By setting the adhesive surface 327 as a curved surface, the bonding area between the light-transmitting cover plate 11 and the housing 30 can be increased, which is beneficial to improving the stability and strength of the bonding.

[0158] See also Fig.16 , Fig. 20 and Fig.21 In some other embodiments, the glue hanging surface 327 may also be a plane.

[0159] By setting the glue hanging surface 327 as a flat surface, it is easy to process and the production cost can be reduced.

[0160] Of course, the glue-hanging surface 327 may also be a curved surface of other shapes, as long as the curved surface can be glue-hanged, and this embodiment does not make any specific limitation on this.

[0161] Please continue reading Fig.13 The embodiment of the present application further provides an electronic device 100 , which includes a screen 1 , a housing 30 , and an adhesive layer 40 disposed between the screen 1 and the housing 30 and connecting the screen 1 and the housing 30 .

[0162] The screen 1 includes a light-transmitting cover plate 11 , wherein the light-transmitting cover plate 11 includes an edge portion, and the edge portion includes a back surface 111 and a side surface 112 connected to each other.

[0163] The bearing surface 321 is opposite to the back surface 111 , the limiting surface 322 is opposite to the side surface 112 , the adhesive layer 40 is arranged between the bearing surface 321 and the back surface 111 and between the limiting surface 322 and the side surface 112 , and the transparent cover plate 11 is connected to the shell 30 through the adhesive layer 40 .

[0164] In this way, by setting a limiting surface 322 on the shell 30, after the screen 1 is accommodated in the accommodating groove 33, the limiting surface 322 can limit the bottom of the edge part in the horizontal direction, and the part of the glue layer 40 located between the supporting surface 321 and the back surface 111 can limit the edge part in the vertical direction, thereby reducing the movement of the screen 1 when erasing the glue, and playing a role of pre-fixing.

[0165] In addition, the limiting surface 322 is formed on the shell 30, which can ensure that no displacement occurs during the assembly process. It is also beneficial to improve the limiting accuracy and limiting effect of the limiting surface 322 on the screen 1 in the horizontal direction, thereby improving the reliability of the electronic device 100.

[0166] In some embodiments, the housing 30 includes a glue-conducting surface 326, and the glue layer 40 covers a portion of the surface of the glue-conducting surface 326, that is, the end of the side surface 112 away from the back surface 111 is higher than the third end of the glue-conducting surface 326, and lower than the fourth end of the glue-conducting surface 326. In this way, the gap between the limiting surface 322 and the side surface 112 is smaller, making it easier for glue to fill the gap, which is beneficial to improve the bonding effect between the transparent cover plate 11 and the housing 30, and further improve the reliability of the electronic device 100.

[0167] Continue reading Fig.14 In some other embodiments, the surface of the adhesive layer 40 exposed from the adhesive conductive surface 326 is flush with the third end of the adhesive conductive surface 326 , that is, the end of the side surface 112 away from the back surface 111 is flush with the third end of the adhesive conductive surface 326 .

[0168] Continue reading Fig.15, the surface of the adhesive layer 40 exposed from the adhesive conductive surface 326 is lower than the third end of the adhesive conductive surface 326, that is, the end of the side surface 112 away from the back surface 111 is lower than the third end of the adhesive conductive surface 326. Such a configuration can also make the gap between the limiting surface 322 and the side surface 112 smaller, making it easier for the glue to fill the gap, thereby facilitating the bonding effect between the light-transmitting cover plate 11 and the housing 30, and further improving the reliability of the electronic device 100.

[0169] See also Fig. 22 The present application also provides an electronic device assembly method, the method comprising:

[0170] Step S100: applying glue on the bearing surface of the shell, and placing the screen in the receiving groove of the shell along the limiting surface.

[0171] Step S200: dispensing glue on the glue-conducting surface, and allowing the glue to fill the gap between the side surface of the light-transmitting cover plate and the limiting surface.

[0172] Step S300: wiping the glue to complete the assembly of the screen and the shell.

[0173] By setting the limiting surface 322, the screen 1 can be smoothly accommodated in the accommodating groove 33 and limited to avoid the screen 1 moving when the glue is wiped; by setting the glue guiding surface 326, the glue can smoothly flow into the gap between the transparent cover plate 11 and the limiting surface 322 and fill the entire gap, thereby improving the bonding effect and ultimately ensuring the reliability of the electronic device 100 and a high screen-to-body ratio.

[0174] Continue reading Fig.16 In some embodiments, the housing 30 includes a rubber surface 327 , and the rubber layer 40 covers the rubber surface 327 , that is, an end of the side surface 112 away from the back surface 111 is higher than the rubber surface 327 .

[0175] In this way, by completely covering the adhesive surface 327 with the adhesive layer 40 , it is helpful to increase the bonding area between the light-transmitting cover plate 11 and the housing 30 and to ensure the aesthetic appearance of the electronic device 100 .

[0176] It should be noted that the electronic device 100 provided in the embodiment of the present application is an electronic device with a flat screen, and can be a foldable electronic device or a non-foldable electronic device.

[0177] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0178] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
