As shown in fig. 2 and 3, the rear shell 12 may have a curved surface on its periphery. The rear case 12 may include a rear case main body portion 122 and a rear case edge portion 121. The rear case main body portion 122 has a substantially flat plate shape. The edge 122a of the rear case main body part 122 may have a rounded rectangular shape. The rear case edge part 121 is connected to the rear case main body part 122 and to the outer periphery of the rear case main body part 122, and may be integrally connected. Schematically, the rear shell edge portion 121 in fig. 2 and 3 extends continuously around the outside of the rear shell edge portion 121, which may enclose a closed loop. The rear case edge part 121 is connected not only to the four straight sides of the edge 122a of the rear case edge part 121 but also to circular arc lines at the four corners of the edge 122 a. In other embodiments, the rear shell edge portion may not extend continuously, but may include a plurality of segments (e.g., four segments) that are spaced apart from one another (e.g., there may be a gap between the segments, wherein the gap extends through a portion of the rear shell body portion and the rear shell edge portion). Such a rear shell edge portion may enclose an open ring shape.

Or in other embodiments, a part of the edge of the rear shell is a curved surface (e.g., an arc-shaped bent plate), for example, two opposite longer side edges of the rear shell are curved surfaces, and this part of the edge in the curved surface shape can be referred to as a first rear shell edge part. The other part edge of the rear shell is flat plate-shaped and can be called as a second rear shell edge part.

As shown in fig. 2 and 3, the rear case edge part 121 may have an arc-shaped bent plate shape, and the rear case edge part 121 may be bent toward the screen cover 11. A projection of the rear case edge portion 121 in a direction perpendicular to the rear case main body portion 122 falls outside the boundary of the rear case main body portion 122. The material of the rear case 12 may be glass.

In other embodiments, the shape of the edge portion of the rear shell is not limited to the arc shape, and may be other shapes capable of matching with the edge of the cover plate. In order to ensure the appearance effect, the edge part of the rear shell can be in a smooth curved surface shape. In other embodiments, the rear housing 12 may be made of other materials.

As shown in fig. 3, adjacent sides of the rear housing edge portion 121 may form an included angle (e.g., approximately 90 degrees), and the intersection of the adjacent sides may be referred to as a corner. The rear shell edge 121 may have second notches 12a at four corners, that is, the exemplary rear shell edge 121 may have four second notches 12a. The shape of the second notch 12a can be designed as required, and for example, it can be an arc. The contour of the second notch 12a may be a curved shape that is arched toward the rear case main body portion 122. The second notch 12a is formed only in the rear case edge 121 and does not penetrate a partial region of the rear case body 122, so that the rear case edge 121 may be formed in a closed loop shape. In an embodiment, a boundary of the second gap may extend to the rear shell main body, the second gap is formed on both the rear shell edge portion and the rear shell main body, and the second gap may divide the rear shell edge portion into several segments (e.g. four segments) spaced from each other, so that the rear shell edge portion may surround an open ring shape.

In other embodiments, the second notches 12a may be formed only at one or more corners of the rear case edge 121, and not at all corners. Alternatively, the second notch 12a may not be provided in other embodiments.

As shown in fig. 1 to 3, in the electronic device 10, the rear case main body portion 122 of the rear case 12 and the cover main body portion 112 of the screen cover 11 are opposed to each other with a space therebetween. The rear case edge portion 121 of the rear case 12 is bent toward the cover edge portion 111 of the screen cover 11, and an end portion of the rear case edge portion 121 is engaged with an end portion of the cover edge portion 111. The display panel 13 and the middle case 14 are located between the screen cover 11 and the rear case 12. In another embodiment, in the case where only a part of the edge of the rear case is curved, the end of the cover edge is bonded to the end of the first rear case edge of the rear case. Different from the embodiment, there may be another appearance component between the screen cover and the rear shell in other embodiments, and the appearance component may connect the second rear shell edge and the area of the screen cover corresponding to the second rear shell edge.

As shown in fig. 3 and 4, the first notch 11a of the cover edge 111 and the second notch 12a of the rear housing edge 121 may form a filling space 10a. The filling spaces 10a may be, for example, four. In addition, the area of the cover edge 111 where the first notch 11a is not provided and the area of the rear case edge 121 where the second notch 12a is not provided may have a fitting gap 10b therebetween, and the fitting gap 10b may communicate with the filling space 10a. The fitting slit 10b may be linear, for example.

As shown in fig. 2 and 4, in the first embodiment, the electronic device 10 may further include a glue material 15 filled in the filling space 10a and the matching gap 10b. The glue material 15 can fill the filling space 10a and the matching gap 10b to connect the screen cover 11 and the rear case 12, so as to seal the display panel 13 and the middle case 14 within the space enclosed by the screen cover 11 and the rear case 12. The rubber material 15 has adhesive property and impact resistance. The liquid glue 15 is relatively hard after being cured, for example, the hardness after being cured may be 60D-100D, and exemplary hardnesses may be 60D, 70D, 90D, and 100D. The rubber 15 can be an external component of the electronic device 10 (especially, a portion of the rubber 15 located in the filling space 10 a). In addition, the adhesive strength of the adhesive material 15 may be 2Mpa to 20Mpa, such as 2Mpa, 10Mpa, 20Mpa, to ensure that the screen cover 11 and the rear case 12 can be reliably connected.

When the electronic apparatus 10 is subjected to an impact (e.g., a drop test or a roll test), corners of the electronic apparatus 10 are easily damaged, for example, chipped. The material at the corners of the cover plate edge 111 and the rear shell edge 121 is removed to form a gap, and the gap is filled with the rubber material 15, so that the risk of damage to the corners can be reduced or avoided by using the impact resistance of the rubber material 15, and the structural reliability of the electronic device 10 is improved. In other embodiments, the corners of the electronic device 10 may not be provided with the notches or the filling adhesive 15 according to actual design conditions or product requirements.

As shown in fig. 2, the display panel 13 of the first embodiment may have a flat plate shape, so that the electronic device 10 can implement a flat display. Alternatively, the edge of the display panel in the embodiment of the present application may also be bent to form an arc, that is, the display panel is a curved display panel, so that the electronic device 10 can implement curved display. The embodiment of the present application does not limit the specific structure of the display panel.

Fig. 5 is an enlarged schematic structural diagram of the middle shell 14 of the electronic device 10 in fig. 2, and fig. 6 is a schematic structural diagram of the middle shell 14 at another viewing angle. As shown in fig. 5 and 6, the middle shell 14 may have a substantially plate shape. The specific structure of the middle shell 14 can be designed according to needs, and the embodiment is not limited. The center housing 14 may have a side 14a and a back 14b that are connected. As shown in fig. 2, 5 and 6, the rear surface 14b may face the rear case main body portion 122. The side surface 14a surrounds the back surface 14b, and the shape of the side surface 14a can be matched with the cover plate edge part 111 and the rear shell edge part 121. The middle case 14 is used for carrying the screen cover 11, the display panel 13 and the rear case 12, and can also be used as an attachment of the adhesive material 15.

In the first embodiment, the middle shell 14 may further be provided with an antenna micro-slot, and the antenna micro-slot is used for realizing radiation and reception of an antenna signal. Since the middle case 14 is sealed in the space enclosed by the screen cover 11 and the rear case 12, the antenna slit is also hidden inside. This prevents the antenna micro-gap from being exposed on the exterior surface of the electronic device 10 (the antenna micro-gap of the conventional electronic device is exposed), which is advantageous for achieving a neat appearance of the electronic device 10. In other embodiments, the center housing 14 may not need to have an antenna slit.

In the first embodiment, a support structure (spacer) may be disposed on the middle housing 14, and the support structure is used for supporting and limiting the screen cover 11 and the rear housing 12, so as to prevent the cover edge 111 and the rear housing edge 121 from having an assembly step difference.

As shown in fig. 5 and 6, in the first embodiment, the electronic device 10 may further include an adhesive 16, a dispensing layer 17, and an adhesive 18. The back adhesive 16 and the dispensing layer 17 can be disposed on the side surface 14a of the middle shell 14, and the back adhesive 18 can be disposed on the back surface 14b of the middle shell 14. The adhesive 16 and 18 are a composite material in which an adhesive is applied to a substrate, and may be in the form of a sheet. The dispensing layer 17 is an adhesive layer formed by a dispensing process.

As shown in fig. 2, 5 and 6, the display panel 13 may be mounted on a surface of one side of the middle case 14, and may be adhered to the surface of the middle case 14 by an adhesive. The cover edge portion 111 is bonded to the side surface 14a of the middle case 14 by the back adhesive 16. The rear case main body 122 is bonded to the rear surface 14b of the middle case 14 by the back adhesive 18. The rear shell edge portion 121 is bonded to the side surface 14a of the middle shell 14 by the spot adhesive layer 17. Thereby, the display panel 13, the cover plate 11, and the rear case 12 can be easily and reliably assembled with the middle case 14. Since the cover main body 112 is required to transmit light emitted from the display panel 13, there is no glue between the cover main body 112 and the rear case 12 to avoid blocking light. Since the rear case 12 does not need to transmit light, both the rear case main body portion 122 and the rear case edge portion 121 of the rear case 12 can be bonded to the rear case 12 by glue, so as to ensure the connection strength.

The electronic device 10 according to the first embodiment includes a screen cover 11 and a rear case 12, the screen cover 11 is connected to the rear case 12 through a glue material 15, a middle case 14 is hidden inside, and an external surface of the electronic device 10 is mainly formed by the screen cover 11 and the rear case 12. The design ensures that the appearance surface has fewer layers and is simpler in appearance. Moreover, the gaps on the appearance surface are small, and the length of the gaps is small, so that the waterproof design difficulty of the electronic device 10 is reduced, and the waterproof performance of the electronic device 10 is easily ensured.

In contrast, a conventional electronic device 10' as shown in fig. 7 includes an external appearance part including a screen cover 11', a middle case 14', and a rear case 12', and an external appearance surface thereof is formed by the screen cover 11', the middle case 14', and the rear case 12 '. The display panel 13' is enclosed between the screen cover 11' and the middle case 14 '. In contrast, the electronic device 10' has a more layered appearance surface and a more complex appearance. Moreover, large-section gaps are formed between the screen cover plate 11 'and the middle shell 14', and between the middle shell 14 'and the rear shell 12', which may increase the difficulty of the waterproof design of the electronic device 10', so that the waterproof performance of the electronic device 10' is not easily ensured.

In the first embodiment, the same material may be used for the screen cover 11 and the rear housing 12, and a suitable process is adopted to make the screen cover 11 and the rear housing 12 present the same appearance effect. The appearance effect includes but is not limited to elements such as color, luster, texture, etc. The glue material 15 filled in the filling space 10a and the matching gap 10b can be processed, so that the glue material 15 can maintain consistent appearance effect with the screen cover plate 11 and the rear shell 12. For example, the adhesive material 15 may be ground and polished after being cured, so that the adhesive material 15 has the same appearance as the screen cover 11 and the rear case 12. In order to ensure the quality of the grinding and polishing process, the glue material 15 may be glue with a hardness of 60D-100D after curing, a modulus of 3Gpa-10Gpa (e.g., 3Gpa, 6Gpa, 10 Gpa), a shrinkage after curing of less than or equal to 1% (e.g., 0.2%, 0.5%, 1%) and a refractive index close to that of the screen cover 11 (e.g., 1.5-1.51, inclusive). As such, and with reference to fig. 8, the exterior surface of the electronic device 10 may exhibit a near seamless effect, and the appearance of the electronic equipment 10 is extremely simple, the whole machine is highly integrated, and the appearance quality is improved. Especially, when the screen cover 11 and the rear case 12 are made of glass materials, the electronic device 10 can have an integrated glass appearance texture due to the design of the first embodiment, and the appearance experience of the product is greatly enhanced. It will be appreciated that the dotted lines in figure 8 are for the purpose of enhancing the cubic effect shown and are not the edges that would be seen in an actual product.

In contrast, in the electronic device 10' shown in fig. 7, the plurality of appearance components are different in material and surface process, and have a large number of appearance layers, so that it is difficult to achieve a compact and integrated appearance design, and there are many gaps on the appearance layers.

Fig. 9 shows a partial cross-sectional structure of an electronic device 20 according to a second embodiment. As shown in fig. 9, the electronic device 10 according to the first embodiment is different:

in the electronic device 20, the entire cover edge portion 211 connected to the cover main body portion 212 is not in the shape of an arc bent plate. The cover edge portion 211 has an arc surface 211a, a connection surface 211c, and a plane 211b. The arc surface 211a is located on a side of the cover edge portion 211 facing away from the rear case main body portion 222 of the rear case 22, the flat surface 211b faces the rear case main body portion 222, and the connection surface 211c connects the arc surface 211a and the flat surface 211b. That is, the screen cover 21 of the electronic device 20 has a substantially flat plate shape as a whole, and the edge of the display-side surface of the screen cover 21 has a curvature.

Similarly to the rear case 12 of the electronic apparatus 10, in the electronic apparatus 20, the edge of the rear case main body portion 222 of the rear case 22 may have a rounded rectangular shape, and the rear case edge portion 221 may be connected to four straight sides of the edge of the rear case main body portion 222. The height (the size in the vertical direction in the view of fig. 9) of the rear case edge part 221 may be large, and the outer surface of the rear case edge part 221 may serve as the side surface of the electronic apparatus 20. The rear case 22 may enclose the screen cover 21 and the middle case 24. The corner of the rear shell edge 221 may be opened with a notch 22a, the notch 22a may penetrate through both the rear shell edge 221 and the rear shell body 222, such notch 22a divides the rear shell edge 221 into several segments (e.g. four segments) spaced from each other; alternatively, the notch 22a may only penetrate through the rear shell edge portion 221 and not extend to the rear shell main body portion 222, such that the notch 22a makes the rear shell edge portion 221 in a closed loop shape, and the rear shell edge portion 221 surrounds the rear shell main body portion 222 for one circle. The gap 22a may be filled with the adhesive material 15. Further, a fitting gap 20a may be formed between the rear case edge portion 221 and the cover edge portion 211, and the fitting gap 20 may be filled with a rubber material 15, and the rubber material 15 may connect the connecting surface 211c of the rear case edge portion 221 and the cover edge portion 211.

The second embodiment also enables the electronic device 20 to have fewer layers of appearance surfaces and a simpler appearance. Moreover, the gaps on the appearance surface of the electronic device 20 are small, and the length of the gaps is small, so that the waterproof design difficulty of the electronic device 20 is reduced, and the waterproof performance of the electronic device 20 is easily ensured; the appearance surface of the electronic equipment 20 can show an approximately seamless effect, the whole machine is highly integrated, and the appearance quality is improved; the risk of damage to the corners of the electronic device 20 can be reduced or avoided, and the structural reliability of the electronic device 20 is improved.

In contrast, a conventional electronic device 20' as shown in fig. 10 includes external appearance parts including a screen cover 21', a front case 23', a middle frame 24', and a rear case 25', whose external appearance is formed by the screen cover 21', the front case 23', the middle frame 24', and the rear case 25 '. In contrast, the electronic device 20' has a more layered appearance surface and a more complex appearance. Moreover, large gaps are formed between the screen cover plate 21 'and the front shell 23', between the front shell 23 'and the middle frame 24', and between the middle frame 24 'and the rear shell 25', which increases the difficulty of the waterproof design of the electronic device 20 'and makes the waterproof performance of the electronic device 20' not easy to be ensured. In the electronic device 20' shown in fig. 10, the plurality of appearance members are different in material and surface process, and the appearance layers are more in order, so that it is difficult to achieve a compact and integrated appearance design.

The structure of the electronic apparatus of the embodiment of the present application is described above in detail. A method of manufacturing an electronic apparatus of the embodiment of the present application will be described below.

Embodiment three provides a manufacturing method 100 of an electronic device, and the manufacturing method 100 can be used for manufacturing the electronic device 10 in embodiment one. The manufacturing method 100 may include the steps of:

s1, providing a screen cover plate and a rear shell; the screen cover plate comprises a cover plate main body part and a cover plate edge part which are connected, wherein the edge of the cover plate main body part is in a round corner rectangle shape, the cover plate edge part is connected with four straight edges of the edge of the cover plate main body part, the cover plate edge part is in a bent shape, and a first notch is arranged at a corner of the cover plate edge part; the rear shell comprises a rear shell main body part and a rear shell edge part which are connected, the edge of the rear shell main body part is in a round corner rectangle shape, the rear shell edge part is connected with four straight edges of the edge of the rear shell main body part, the rear shell edge part is in a bent shape, and a second notch is arranged at a corner of the rear shell edge part;

s2, aligning the screen cover plate with the rear shell, enabling the end part of the edge part of the cover plate to be opposite to the end part of the edge part of the rear shell at intervals to form a matching gap, and enabling the first gap and the second gap to form a filling space together; wherein the mating gap is in communication with the fill space;

s3, filling a glue material between the end part of the edge part of the cover plate and the end part of the edge part of the rear shell, so that the glue material fills the filling space and the matching gap, and bonding the end part of the edge part of the cover plate and the end part of the edge part of the rear shell;

and S4, after the glue material is solidified, grinding and polishing the glue material.

As will be described in detail below.

Referring to fig. 2 and 3, schematically, the screen cover in S1 may be the screen cover 11 described above. The peripheral edge of the screen cover 11 may be a curved surface. The screen cover 11 may include a cover main body portion 112 and a cover edge portion 111. The cover main body portion 112 has a substantially flat plate shape. The cover edge portion 111 is formed in a closed ring shape and is connected around the outer circumference of the cover main body portion 112. The cover edge portion 111 may have an arc-shaped bent plate shape. The projection of the cover edge 111 in the direction perpendicular to the cover main body 112 falls outside the boundary of the cover main body 112.

Alternatively, the cover edge of the screen cover in S1 is connected to the outer periphery of the cover main body 112, but the shape of the cover edge may not be limited to an arc shape, and may be other curved shapes. In order to ensure the appearance effect, the edge part of the cover plate can be in a smooth curved surface shape.

The following description is continued by taking the screen cover in S1 as the screen cover 11 as an example.

As shown in fig. 3, adjacent two sides of the cover plate edge portion 111 in S1 may form an included angle (e.g., approximately 90 degrees), and the intersection of the adjacent two sides may be referred to as a corner. Illustratively, the first notches 11a may be formed in the corners around the edge portion 111 of the cover plate, that is, four first notches 11a may be formed in the edge portion 111 of the cover plate. The shape of the first notch 11a may be designed as required, and may be, for example, an arc shape. The contour of the first notch 11a may be a curved shape that is arched toward the cover main body portion 112. Alternatively, the first notches 11a in S1 may be formed only at one or some of the corners of the cover edge 111, but not at all of the corners.

As shown in fig. 2 and 3, the rear case in S1 may be the rear case 12 described above. The rear case 12 may include a rear case main portion 122 and a rear case edge portion 121. The rear case main body portion 122 may have a substantially flat plate shape. The rear case edge portion 121 has a closed ring shape and is connected around the outer periphery of the rear case main body portion 122. The rear case edge portion 121 may have an arc-shaped bent plate shape. A projection of the rear case edge portion 121 in a direction perpendicular to the rear case main body portion 122 falls outside the boundary of the rear case main body portion 122. Alternatively, the rear case edge of the rear case in S1 is connected to the outer periphery of the rear case main body 122, but the shape of the rear case edge may not be limited to an arc shape, and may be other curved shapes that can be engaged with the cover edge in S1. In order to ensure the appearance effect, the rear shell edge part can be in a smooth curved surface shape.

The following description is continued by taking the case where the rear case in S1 is the rear case 12 as an example.

As shown in fig. 3, adjacent sides of the rear housing edge portion 121 may form an included angle (e.g., approximately 90 degrees), and the intersection of the adjacent sides may be referred to as a corner. Illustratively, the rear shell edge 121 may have second notches 12a at four corners, that is, the rear shell edge 121 may have four second notches 12a. The shape of the second notch 12a may be designed as required, and may be, for example, an arc shape. The contour of the second notch 12a may be a curved shape that is arched toward the rear case main body portion 122. Alternatively, the second notches 12a may be formed only at one or some of the corners of the rear case edge 121, and not at all of the corners.

Referring to fig. 2, schematically, both the screen cover 11 and the rear case 12 may be assembled to the middle case 14 in S2. The middle case 14 may be pre-installed with the display panel 13 (for example, the display panel 13 may be adhered to the middle case 14 by a back adhesive), and other components (for example, a battery, a circuit board assembly, etc.). As shown in fig. 5 and 6, the middle housing 14 may have a side surface 14a and a back surface 14b, which are connected. The side surface 14a surrounds the back surface 14b, and the shape of the side surface 14a can be matched with the cover plate edge part 111 and the rear shell edge part 121.

As shown in fig. 2, 5 and 6, in S2, the screen cover 11 may be positioned to a side of the middle case 14 where the display panel 13 is installed, so that the screen cover 11 covers a part of the surface of the middle case 14, and the cover edge 111 of the screen cover 11 is bonded to the side surface 14a, for example, by the adhesive 16. The rear shell 12 may be positioned to the other side of the middle shell 14, such that the rear shell 12 covers another part of the surface of the middle shell 14, the rear shell main body portion 122 is bonded to the back surface 14b of the middle shell 14 through the back adhesive 18, and the rear shell edge portion 121 of the rear shell 12 is bonded to the side surface 14a of the middle shell 14 through the spot adhesive layer 17. In S2, the order of adhering the screen cover 11 to the middle shell 14 and adhering the rear shell 12 to the middle shell 14 may be determined according to actual needs, and this embodiment is not limited strictly.

In S2, the screen cover 11, the middle case 14 (including the components mounted on the middle case 14), and the rear case 12, which are bonded together, may be collectively referred to as a pre-assembly. Illustratively, the pre-assembly may be subjected to pressure holding to cure the adhesive therein (the above-mentioned back adhesive and adhesive layer) and reduce or eliminate the step difference between the cover edge portion 111 and the rear case edge portion 121. The level difference refers to a level difference in a direction parallel to the cover main body portion 112. Eliminating this step can avoid the hand from scraping when the side of the electronic device 10 is touched by a human hand.

Fig. 11 shows the pressure holding jig 40 being used to hold the pressure on the preassembly 30, and fig. 12 is a schematic sectional view of B-B in fig. 11, wherein the preassembly 30 is not shown in a sectional view for simplicity and emphasis. As shown in fig. 11 and 12, schematically, the pressure holding jig 40 may include a plurality of pressure holding portions 41 (e.g., 4). The pressure retention portion 41 may translate to grip the preassembly 30 or to release the preassembly 30. The plurality of pressure holding portions 41 may be translated in different directions, respectively, for example, as shown in fig. 11, the pressure holding portions 41 may be translated in horizontal and vertical directions, respectively.

As shown in fig. 11 and 12, the pressure retaining portion 41 may have a pressure retaining surface 41a and a pressure retaining surface 41b, and the pressure retaining surface 41a and the pressure retaining surface 41b may be continuous. The pressure retention surface 41a follows the outer surface of the cover plate edge portion 111, i.e., the pressure retention surface 41a is similar to the outer surface of the cover plate edge portion 111, and the pressure retention surface 41a can substantially completely conform to the outer surface of the cover plate edge portion 111. The pressure retention surface 41b is contoured to the outer surface of the shell edge 121, i.e., the pressure retention surface 41b is similar to the outer surface of the shell edge 121, and the pressure retention surface 41b may substantially completely conform to the outer surface of the shell edge 121. It is understood that the pressure maintaining jig 40 may also include other structures, which are not the focus of the present embodiment and therefore will not be described herein. The specific structure of the pressure maintaining jig 40 can be designed as required, and this embodiment is not limited.

Referring to fig. 11 and 12, in S2, the pre-assembly 30 may be positioned on the pressing jig 40, and the plurality of pressing portions 41 may be moved to clamp different sides of the pre-assembly 30. The cover plate edge 111 is covered by the pressure maintaining surface 41a of the pressure maintaining portion 41, the rear shell edge 121 is covered by the pressure maintaining surface 41b of the pressure maintaining jig 40, and the cover plate edge 111 and the rear shell edge 121 are pressed by the pressure maintaining portion 41 with a constant pressure. After the set period of time has elapsed, the pressure retaining portion 41 is retracted to release the pre-assembly 30.

In this process, the adhesive between the screen cover 11 and the middle case 14 and the adhesive between the rear case 12 and the middle case 14 are cured, so that the screen cover 11 and the rear case 12 can be reliably adhered to the middle case 14. Moreover, due to the pressing action of the pressure retaining part 41, the cover plate edge part 111 and the rear shell edge part 121 can be accurately aligned, and the step difference is not easy to occur after the adhesive is cured, so that the assembly precision is ensured. In other embodiments, the step of holding the pressure of the pre-assembly 30 by the pressure holding jig 40 may not be performed according to actual needs.

As shown in fig. 13, after S2, the first notch 11a on the cover edge portion 111 and the second notch 12a on the rear case edge portion 121 may together form the filling space 10a. The filling spaces 10a may be, for example, four. In addition, a matching gap 10b may be formed between the region of the cover edge 111 where the first notch 11a is not formed and the region of the rear case edge 121 where the second notch 12a is not formed, and the matching gap 10b may communicate with the filling space 10a. The fitting slit 10b may be linear, for example.

In S3, the fitting gap 10b and the filling space 10a may be filled with the sealant 15 by a filling jig. Fig. 14 is a schematic structure of the filling jig 50, wherein the filling jig 50 is represented by an integral wire frame for highlighting the emphasis, which is merely an illustration, and the filling jig 50 may be actually assembled by several components.

As shown in fig. 14, the filling jig 50 may have an outer shape substantially similar to that of the preassembly 30. The filling jig 50 has a housing cavity 50a therein, and the housing cavity 50a is formed to follow the outer surface of the electronic device 10 shown in fig. 8. When the preset 30 is loaded into the housing cavity 50a, the inner wall of the housing cavity 50a can closely fit with the outer surface of the preset 30. The wall of the receiving cavity 50a is provided with a filling through hole 50b and a negative pressure through hole 50c, and both the filling through hole 50b and the negative pressure through hole 50c are communicated with the receiving cavity 50a and the outside. The positions of the filling through hole 50b and the negative pressure through hole 50c on the filling fixture 50 can be designed according to the requirement, for example, the filling through hole and the negative pressure through hole can be respectively located on two opposite short sides of the filling fixture 50. When the pre-assembly 30 is loaded into the receiving cavity 50a, the filling through hole 50b can be aligned with the matching gap 10b, so that the glue material 15 entering from the filling through hole 50b can enter the matching gap 10b (the following description will be continued by way of example). Alternatively, when the preassembly 30 is loaded into the receiving cavity 50a, the filling through hole 50b may be aligned with the filling space 10a, so that the adhesive 15 entering from the filling through hole 50b can enter the filling space 10a. In addition, the number of the filling through holes 50b and the negative pressure through holes 50c may be designed as required, and the number shown in fig. 14 is merely an illustration.

Referring to fig. 15, in S3, the pre-assembly 30 is loaded into the accommodating cavity 50a of the filling jig 50, so that the outer surface of the pre-assembly 30 is attached to the inner wall of the accommodating cavity 50 a. At this time, only the fitting gap 10b and the filling space 10a between the outer surface of the pre-assembly 30 and the inner wall of the receiving cavity 50a may constitute a flow path, and the other regions are substantially "solid".

In S3, after the pre-assembly 30 is clamped, the glue 15 is injected into the filling through hole 50b, and the glue 15 may be liquid glue, for example. The cured rubber 15 may have a hardness of 60D to 100D, a shrinkage rate of xxx after curing, and a transparency close to that of the screen cover 11 (e.g., 1.5).

In S3, the adhesive material 15 may enter the receiving cavity 50a and enter the matching gap 10b. Illustratively, after entering the fitting slit 10b, the adhesive material 15 may flow in two paths in the flow channel. For example, in the view of fig. 15, after entering the receiving cavity 50a through the filling through hole 50b, the glue material 15 can be divided into two paths, one path flows in the matching gap 10b on the left side of the filling through hole 50b, and the other path flows in the matching gap 10b on the right side of the filling through hole 50 b. The glue material 15 can flow into the filling space 10a through the matching gap 10b and then flow into the next matching gap 10b through the filling space 10a. In S3, air can be extracted through the negative pressure through hole 50c to discharge air in the accommodating cavity 50a (i.e. discharge air in the flow channel), so that the flow of the rubber material 15 in the flow channel can be promoted, the filling quality of the rubber material 15 to the flow channel is ensured, and the defects of insufficient filling and air trapping in the local area of the flow channel are avoided.

In this embodiment, the filling jig 50 is used to accurately fill the adhesive material 15, and the region of the pre-assembly member 30 that does not need to be filled is protected. In other embodiments, the glue material 15 can be filled by other reasonable processes according to the product requirement, and is not limited to the use of the filling fixture 50.

In S4, in order to facilitate manufacturing of integrated glass appearance texture, the screen cover 11 and the rear case 12 may be manufactured using glass. And, the rubber material 15 filled in the flow channel can be ground and polished after being cured, so that the appearance effects of the rubber material 15, the screen cover plate 11 and the rear shell 12 are the same. Automated equipment may be used for grinding and polishing to achieve better surface finish. Because the glue material 15 with the hardness of 60D-100D, the modulus of 3Gpa-10Gpa, the shrinkage rate of 1% or less and the refractive index close to that of the screen cover plate 11 (for example, 1.5-1.51, inclusive) is used after curing, the appearance effect of the glue material 15 after grinding and polishing can be ensured to be consistent with that of the screen cover plate 11 and the rear shell 12, so that the appearance surface can be manufactured to be approximately seamless, and the electronic device 10 can present highly integrated and extremely simple glass appearance texture. Schematically, the present embodiment allows the rubber material 15 to satisfy the ranges of the above parameters at the same time. In other embodiments, other glue materials may be used, as required by the product, such that the glue material meets any one or any number of the above parameter ranges.

In other embodiments, the screen cover 11 and/or the rear case 12 may not be glass, depending on the product requirements. The rubber material 15 with other performance parameters can be selected according to the requirement.

In this embodiment, after the grinding and polishing process of S4, the functional film layers on the screen cover 11 and the rear case 12, including but not limited to an anti-fingerprint film (AF), may be damaged. Therefore, after S4, the functional film layer can be recoated. For example, the functional film layer may be re-coated on the outer surfaces of the cover plate edge portion 111, the adhesive material 15 and the rear case edge portion 121.

The above description is only for the specific embodiments of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present application, and shall be covered by the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
