Referring to fig. 1 and fig. 2 together, fig. 1 is a schematic structural diagram of an embodiment of an electronic device provided in the present application, and fig. 2 is a schematic exploded structural diagram of the electronic device in fig. 1.

The electronic device 10 of the embodiment of the present application may be a portable device such as a mobile phone, a tablet computer, a notebook computer, and a wearable device. The embodiment of the present application takes the electronic device 10 as a mobile phone as an example for description. The electronic device 10 includes a display module 11, a housing 12, and a middle frame 13. The display module 11 and the housing 12 are respectively connected to the middle frame 13, so that the three components are assembled to form a basic structure in which the display module 11 and the housing 12 clamp the middle frame 13 together, as shown in fig. 1. For example, the display module 11 and the housing 12 are respectively covered on two opposite surfaces of the middle frame 13 by one or a combination of assembling manners such as clamping, gluing, welding, and the like. Further, the battery 14 and other structural components such as a motherboard, a camera module, a fingerprint module, etc. are disposed inside the electronic device 10, so that the electronic device 10 can perform corresponding functions. The structural member is generally disposed in a receiving cavity 15 formed by the display module 11 and the housing 12, and can be mounted and fixed on the middle frame 13, so that the structural member can be stacked inside the electronic device 10 and occupy a certain space.

The display module 11 may be a screen such as an lcd (liquid Crystal display), an OLED (Organic Light-Emitting Diode), a Mini-LED, or a Micro-LED. In the embodiment of the present application, the display module 11 is an OLED screen for example. Generally, the display module 11 includes a transparent cover 111 and a display panel 112, as shown in fig. 2. The display panel 112 may be attached to the transparent cover 111 by using a sealant such as OCA (optical Clear Adhesive) or PSA (Pressure Sensitive Adhesive). The transparent cover 111 may be made of glass or a polyimide film, and is mainly used for protecting the display panel 112, and may be used as an outer surface of the electronic device 10, so that a user can perform touch operations such as clicking and sliding operations. The display panel 112 is mainly used for displaying a screen, and can be used as an interactive interface to instruct a user to perform the touch operation on the transparent cover 111. In some other embodiments, the outer surface of the electronic device 10 (i.e., the outer surface of the transparent cover plate 111) may be further provided with any one of other functional film layers, such as a tempered film, a frosted film, a decoration film, a peep-proof film, a water condensation film, and the like, so that the electronic device 10 can provide different use effects for a user.

The housing 12 may be a battery cover of the electronic device 10, and may be made of glass, metal, plastic, or other electrochromic materials. The housing 12 has a certain structural strength, and is mainly used to protect the electronic device 10 together with the transparent cover 111. Correspondingly, the material of the middle frame 13 may be glass, metal, plastic, etc. The middle frame 13 also has a certain structural strength, and is mainly used for supporting and fixing structural members inside the electronic device 10. Further, since the housing 12 and the middle frame 13 are generally directly exposed to the external environment, the material of the housing 12 and the middle frame 13 may preferably have certain properties of wear resistance, corrosion resistance, scratch resistance, etc., or the outer surface of the housing 12 and the middle frame 13 (i.e., the outer surface of the electronic device 10) may be coated with a layer of functional material for wear resistance, corrosion resistance, scratch resistance, etc. In some embodiments, the housing 12 and the middle frame 13 may be two separate structural members, as shown in fig. 2, and the two may be assembled by one or a combination of clamping, gluing, welding, and the like. In other embodiments, the housing 12 and the middle frame 13 may also be integrally formed, such as by stamping, injection molding, etc.

Generally, the electronic device 10 may have a box-like appearance structure as a whole, that is, the display module 11, the housing 12 and the middle frame 13 may be rectangular. The display module 11 has four side edges, the housing 12 also has four side edges, and the middle frame 13 also has four side edges correspondingly; the two side edges of each structure are generally rounded to enhance the aesthetic appearance and grip of the electronic device 10. Further, at least one side edge of at least one of the display module 11 and the housing 12 connected to the middle frame 13 is a structure bent toward the middle frame 13. In other words, at least one of the four side edges of the display module 11 is bent toward the middle frame 13; and/or at least one of the four side edges of the case 12 is bent toward the middle frame 13.

It should be noted that the side edge in the embodiment of the present application is a simple expression, and the width of the side edge is not considered, and the dimensions of the display module 11, the housing 12, and the middle frame 13 in the thickness direction of the electronic device 10 are not considered. Further, the side edges described in the embodiments of the present application should not be simply understood as lines in a general sense.

In some embodiments, the four side edges of the display module 11 and the four side edges of the housing 12 may be curved toward the middle frame 13, as shown in fig. 1 and 2, that is, the side edges may be curved, so that the display module 11 is curved in four directions in appearance, and the housing 12 is curved in four directions in appearance. The mode that the display module 11 is bent on four sides not only can reduce or even hide the black edge of the display module 11, so that the electronic device 10 can provide a larger display view for a user; the picture that can also make display panel 112 show can extend to its side from the front of display module assembly 11 with the form similar to "waterfall", also be that display module assembly 11 can build a visual effect who surrounds the demonstration promptly to make electronic equipment 10 bring a visual experience that is different from bang screen, water droplet screen, dig the hole screen, flat full-face screen such as over-and-under type camera and sliding closure type camera for the user, and then increase electronic equipment 10's competitiveness. Furthermore, the housing 12 can be bent on four sides to enhance the appearance and the grip of the electronic device 10. In other embodiments, the display module 11 and the housing 12 may have a single-sided curved appearance, a double-sided curved appearance, or a three-sided curved appearance, and one of the display module 11 and the housing 12 may have the curved surface structure. The electronic device 10 in the embodiment of the present application is described by taking a structure in which the display module 11 and the housing 12 are all bent on four sides as an example. The electronic device 10 shown in fig. 1 and 2 only describes a portion (e.g., one quarter) of the display module 11, the housing 12, and the middle frame 13, and the structures of other portions are the same as or similar to those in the drawings, and are not repeated herein. The specific structure of this quarter of the electronic device 10 is described in detail below.

With reference to fig. 1 and fig. 2, the transparent cover 111 includes a main body portion 1111 and a curved portion 1112, the curved portion 1112 surrounds the main body portion 1111 and is in smooth transition with the main body portion 1111; the bent portion 1112 extends toward a direction close to the center frame 13 so that the transparent cover plate 111 is provided in a bent shape. The display panel 112 includes a main display portion 1121 and a sub display portion 1122 which are integrally formed, wherein the sub display portion 1122 surrounds the main display portion 1121, and the main display portion 1121 and the sub display portion 1122 are in smooth transition; the main display portion 1121 is attached to the main body portion 1111, and the sub display portion 1122 is attached to the bent portion 1112 so that the display panel 112 is also provided in a bent shape. In the embodiment of the present application, after the display panel 112 is attached to the transparent cover 111, the minimum bending radius of the sub-display portion 1122 relative to the main display portion 1121 may be 6mm, that is, the minimum curvature radius of the display module 11 may be 6 mm. Taking a mobile phone as an example, the thickness of the whole mobile phone is generally less than 10mm, and the curvature radius of the value enables the display module 11 to have a larger bending depth in the thickness direction of the whole mobile phone, that is, the side surface of the mobile phone can display more pictures, so that the mobile phone can provide a larger display view for a user. Further, the housing 12 includes a flat plate portion 121 and a bent portion 122 integrally formed, the bent portion 122 surrounds the flat plate portion 121, and the two portions are in smooth transition; the bent portion 122 extends toward the middle frame 13, so that the housing 12 is disposed in a curved shape. The bending portion 1112 and the bending portion 122 can be connected to two opposite surfaces of the middle frame 13 by one or a combination of assembling manners such as clamping, gluing, welding, and the like. In other embodiments, the main portion 1111 and the flat plate portion 121 may also be slightly bent, for example, the bending directions of the two are away from each other.

It should be noted that the integrally formed structure in the embodiment of the present application means that the structure of the product is an organic whole, and the product cannot be easily split or divided. For example, the present embodiment may bend a flat tempered glass into the transparent cover 111 disposed in a curved shape according to predetermined process parameters by using a hot bending technique, as shown in fig. 1 and 2, and the curved portion and the straight portion naturally perform a circular arc transition. The above process parameters can be reasonably designed according to factors such as the type of raw material, the bending angle and the curvature radius, and are not limited herein. Further, the OLED screen in a flat plate form or a pre-bent form may be attached to a transparent cover plate 111 disposed in a bent form to form a display panel 112 disposed in a bent form, as shown in fig. 1 and 2, thereby forming the display module 11 disposed in a bent form. For another example, if the housing 12 is made of glass, the flat tempered glass can be bent into the curved housing 12 by the above-mentioned hot bending technique; if the housing 12 is made of metal, a stamping technique can be used to bend the metal plate into the housing 12 in the curved configuration, as shown in fig. 1 and 2, and the curved portion and the straight portion are naturally in the form of an arc. Therefore, in fig. 1 and 2, a line between the main body portion 1111 and the bent portion 1112, a line between the main display portion 1121 and the sub display portion 1122, and a line between the flat plate portion 121 and the bent portion 122 are only intended to illustrate boundaries between the above portions. In other words, for the transparent cover 111, the display panel 112 and the housing 12 in the actual product, the lines are not true, i.e. the transition between the parts is smooth.

The middle frame 13 includes a frame 131 and a middle plate 132, wherein the middle plate 132 is connected to the frame 131 and extends away from the frame 131. The material of the frame 131 may be metal, the material of the middle plate 132 may be plastic, and the two may be made into the middle frame 13 by injection molding, that is, the middle frame 13 may be an integrally formed structural member, so that the structure of the middle frame 13 may be simplified, and the manufacturing cost of the middle frame 13 may be reduced. At this time, the frame 131 may be exposed to the external environment and has an appearance surface capable of playing a role of decoration; the middle plate 132 is mainly located inside the electronic device 10, and can support and fix the battery 14 and other structural components such as a motherboard, a camera module, and a fingerprint module. Furthermore, a battery compartment 133 may be formed on a surface of the middle plate 132 close to the housing 12, and the battery compartment 133 may be a part of the receiving cavity 15 in the electronic device 10, and is mainly used for disposing the battery 14. In other embodiments, for example, when the transparent cover 111 is made of glass and the housing 12 is also made of glass, the middle frame 13 may include only the middle plate 132 without the frame 131 exposed to the external environment, the transparent cover 111 made of glass and the housing 12 may be directly welded by a glass solder, and the middle frame 13 is completely located inside the electronic device 10.

Further, the display module 11 and the housing 12 may not only be four-sided bent in appearance, but also be symmetrical with respect to the middle frame 13 (especially the frame 131) in appearance, as shown in fig. 3, so that the electronic device 10 provides a symmetrical aesthetic feeling for users. At this time, the maximum outline of the electronic device 10 is located on the frame 131 of the middle frame 13, as indicated by the arrow a in fig. 3. In some other embodiments, the display module 11 may further extend toward the middle frame 13 in a curved manner based on the above symmetrical structure, as shown in fig. 4, to increase the lateral display area of the display module 11, so that the electronic device 10 can provide a larger display field of view for the user. At this time, the maximum outline of the electronic device 10 is located at the curved portion 1112 of the display module 11, as indicated by an arrow B in fig. 4.

Based on the above detailed description, although the display module 11 and the housing 12 may be structurally bent toward the middle frame 13 to form a four-sided bent appearance structure, the electronic device 10 can provide a user with a larger display view and better aesthetic appearance and handle feeling; however, the material of the housing 12 has been only one of glass, metal, and plastic for a long time, so that the material and the texture of the housing 12 are single, which causes the user to feel fatigue easily. In addition, the above materials are relatively cold and give a user a poor feeling of touch. For this reason, in the embodiment of the present application, a decoration 16 is further disposed on a side of the housing 12 away from the display module 11, and collectively serves as the housing assembly 100 described in the present application. In this case, the decoration 16 may be attached to a surface of the flat plate portion 121 and the bent portion 122 away from the display module 11 in fig. 2, so that the decoration 16 serves as an external appearance surface of the electronic device 10. Obviously, when the user uses the electronic device 10, the user is no longer in direct contact with the housing 12, but is in contact with the decoration 16 provided on the housing 12, so that the electronic device 10 can provide a unique visual effect and a holding hand feeling for the user.

The specific structure of the housing assembly and its relationship to other structural components in the electronic device are described in detail below.

Referring to fig. 5, fig. 5 is a schematic view of a partial cross-sectional structure of the electronic device of fig. 1 along a V-V direction. It should be noted that the electronic device shown in fig. 5 mainly includes a part of the structure related to the housing 12, and the structures of the display module 11 and the like are not shown.

The housing assembly 100 includes a housing 12 and a garnish 16. The hardness of the decoration 16 may be less than that of the housing 12, that is, the softness of the decoration 16 may be better than that of the housing 12. For example, the housing 12 may be a glass, metal or plastic, and the decoration 15 may be a leather. Since the leather and the plastic have better adhesive performance, so that the decorative element 16 can have greater bonding strength after being adhered to the housing 12 by the adhesive, the housing 12 may preferably be a plastic to prevent the edge of the leather from being raised, thereby increasing the reliability of the housing assembly 100. Further, compared with a glass part, a metal part or a plastic part, the leather part has softer texture and stronger appearance expressive force, and when the electronic device 10 adopts the decoration 16 as the appearance surface of the back surface, the appearance aesthetic feeling and the holding hand feeling of the whole electronic device can be further improved, so that the competitiveness of the electronic device 10 is increased.

The housing 12 includes a first surface 123 and a second surface 124 opposite to each other. For the electronic device 10, since the housing 12 includes the flat plate portion 121 and the bent portion 122 integrally formed, the first surface 123 may be a surface of the flat plate portion 121 and the bent portion 122 that are both far away from the display module 11, and the second surface 124 may be a surface of the flat plate portion 121 and the bent portion 122 that are both close to the display module 11. Further, since the bent portion 122 may be disposed in a curved shape relative to the flat plate portion 121, a portion of the first surface 123 corresponding to the flat plate portion 121 may be a flat surface, and a portion of the first surface 123 corresponding to the bent portion 122 may be an arc surface. Accordingly, a portion of the second surface 124 corresponding to the flat plate portion 121 may be a flat surface, and a portion of the second surface 124 corresponding to the bent portion 122 may be an arc surface.

The first surface 123 and the second surface 124 are connected by a first end surface 125. The decoration 16 may be attached to the first surface 123 and the first end surface 125 by glue, as shown in fig. 5. With such an arrangement, the decoration 16 can cover the housing 12, thereby improving the aesthetic appearance and the holding feeling of the electronic device 10; and can also extend to between the casing 12 and the middle frame 13 (specifically, the frame 132), that is, the edge of the decoration 16 can be hidden between the casing 12 and the frame 132 to prevent the edge of the decoration 16 from lifting, thereby increasing the reliability of the casing assembly 100. At this time, the portion of the decoration 16 contacting the housing 12 and the middle frame 13 may be provided with glue to increase the glue joint area of the decoration 16, thereby increasing the glue joint strength of the decoration 16.

It should be noted that the thickness of the housing 12 may be uniform, that is, for the electronic device 10, the thickness of the bent portion 122 may be equal to the thickness of the flat plate portion 121, so that the distance between the first surface 123 and the second surface 124 may be substantially uniform. Since the electronic device 10 is often assembled by a plurality of structural members, a side (i.e., the second surface 124) of the housing 12 close to the display module 11 may be partially provided with an avoiding structure to avoid structural interference between the housing 12 and other structural members, and may also be partially provided with a reinforcing structure to increase the local strength of the housing 12, thereby increasing the reliability of the housing 12.

Referring to fig. 6, fig. 6 is a schematic cross-sectional view of another embodiment of the housing assembly of fig. 5.

Decorative piece 16 may further be attached to second surface 124 such that decorative piece 16 at least partially wraps around the edge of housing 12, as shown in fig. 6, i.e., the edge of housing 12 is clamped by decorative piece 16. With this arrangement, the garnish 16 is at least partially held by the case 12 and the middle frame 13 together, and the edge of the garnish 16 can be effectively prevented from lifting. However, such an arrangement would again increase the local thickness of the housing assembly 100, thereby affecting the overall structure of the electronic device 10. For example, in the case where the housing 12 is provided in a curved shape, in order to allow the housing assembly 100 to be assembled with the middle frame 13 as it is, the degree of bending of the bent portion 122 with respect to the flat plate portion 121 has to be reduced for the housing 12; for the middle frame 13, the width of the frame 132 in the thickness direction of the electronic device 1 has to be increased to form a space between the rear cover 12 and the middle frame 13, which can accommodate the decoration 16, so that it is structurally feasible that the decoration 16 at least partially covers the edge of the housing 12. Obviously, this reduces the curvature of the housing 12, increases the thickness of the frame 132, makes the back and the side of the electronic device 10 thick, and reduces the aesthetic appearance and the hand feeling of holding the electronic device 10. Therefore, in the embodiment of the present application, the structure of the housing 12, especially the edge portion of the housing 12, is redesigned to meet the requirement that the decoration 16 is wrapped around the housing 12 and the requirement that the housing 12 is disposed in a curved shape. The above structure is specifically described below:

referring to fig. 7 to 9 together, fig. 7 is a schematic cross-sectional structure view of another embodiment of the housing assembly in fig. 5, fig. 8 is a schematic cross-sectional structure view of the housing and the supporting member in fig. 7, fig. 9 is an exploded structural view of the housing assembly in fig. 7, and fig. 10 is a schematic top structural view of the housing and the supporting member in fig. 7.

The housing assembly 100 further includes a supporting member 17, the supporting member 17 is mainly used to replace an edge portion of the housing 12, as shown in fig. 8, the edge portion may specifically be an edge of the bent portion 122 away from the flat plate portion 121, so that the edge of the housing 12 can be thinned to prevent the decorative member 16 from covering behind the edge of the housing 12 and affecting the overall structure of the electronic device 10. Wherein the thickness of the supporting member 17 is smaller than that of the housing 12, and one end of the supporting member 17 is connected with the housing 12 to ensure the structural feasibility.

The supporting member 17 includes a third surface 171 and a fourth surface 172 disposed opposite to each other, and the third surface 171 and the fourth surface 172 are connected by a second end surface 173. The third surface 171 is on the same side as the first surface 123, and the fourth surface 172 is on the same side as the second surface 124, as shown in fig. 8. And the distance between the fourth surface 172 and the first surface 123 is smaller than the distance between the second surface 124 and the first surface 123, so that the side of the housing 12 close to the display module 11 is at least partially thinned to facilitate the covering of the decoration 16. Further, the second end surface 173 is far from the housing 12, and the garnish 16 is attached to the first surface 123, the third surface 171, and the second end surface 173, and can be further attached to the fourth surface 172, as shown in fig. 7. In other words, by providing the support 17 at the edge of the case 12, the garnish 16 is not covered by the case 12 but by the support 17 when attaching the garnish 16. The support 17 and the case 12 may form a step difference in the thickness direction of the electronic apparatus 10. The size of the step may be consistent with the thickness of the decoration 16, so that after the decoration 16 is wrapped on the support member 17, one surface of the decoration 17 away from the fourth surface 172 may be flush with the second surface 124, thereby satisfying the requirement that the decoration 16 is wrapped on the housing 12 (substantially, the support member 17) and the requirement that the housing 12 is disposed in a curved shape.

It should be noted that, with respect to the first surface 123, the distance between the fourth surface 172 and the first surface 123, and the distance between the second surface 124 and the first surface 123, and the difference between the two, can be designed reasonably according to the thickness of the decoration 16. Further, the distance between the second end 173 and the first end 125 can be designed according to the covering requirements of the decoration 16.

Based on the above detailed description, the supporting member 17 is mainly used to enable the edge of the housing 12 to be thinned, especially the side of the housing 12 close to the display module 11. For the side of the housing 12 away from the display module 11, the first surface 123 and the third surface 171 are attached with the decoration 16, and the decoration 16 has a certain flexibility, so that the third surface 171 can be flush with the first surface 123, the third surface 171 can also slightly protrude from the first surface 123, and the third surface 171 can also be slightly recessed into the first surface 123. Preferably, the third surface 171 is flush with the first surface 123, so that the surface of the housing 12 and the supporting member 17 away from the display module 11 is as flat as possible.

The housing 12 may be made of plastic and the supporting member 17 may be made of metal. For example, the metal product is made of one of stainless steel, aluminum alloy, magnesium alloy and titanium alloy. Wherein, the two can adopt the injection molding process, so that the supporting member 17 and the housing 12 form an integral structure. Further, the supporting member 17 may be partially embedded in the housing 12 to increase the bonding strength between the supporting member 17 and the housing 12. As shown in fig. 9, the through holes 174 may be formed in a portion of the supporting member 17 embedded in the housing 12, and the through holes 174 are spaced along the circumferential direction of the housing 12, so that the supporting member 17 and the housing 12 can be engaged with each other after injection molding, thereby increasing the bonding strength between the supporting member 17 and the housing 12, and further increasing the reliability of the housing assembly 100.

Based on the above detailed description, since the decoration 16 is attached to the side of the housing 12 away from the display module 11, the overall thickness of the electronic device 10 is slightly increased, and the curvature between the frame 132 and the housing assembly 100 (i.e. the curvature between the side surface and the back surface of the electronic device 10) of the electronic device 10 is also slightly decreased, which may affect the aesthetic appearance and the holding feeling of the electronic device 10 to some extent. For example, the thickness of housing 12 may be generally 0.5-0.6mm, while the thickness of trim piece 16 may be 0.6-0.8mm, with trim piece 16 attached to housing 12 to undoubtedly add to the overall thickness. In contrast, if the housing 12 is moved toward the display module 11, or the bending degree of the bent portion 122 of the housing 12 relative to the flat plate portion 121 is increased, the space of other structural components in the electronic device 10 is occupied, and even the structural interference between the structural components occurs. For example, the battery 14 is generally disposed between the middle frame 13 and the housing 12, and specifically may be disposed in the battery compartment 133; in order to increase the endurance of the electronic device 10, the capacity of the battery 14 is generally increased as much as possible, i.e. the volume of the battery 14 is increased, so that the battery 14 generally occupies a large space inside the electronic device 10, as shown in fig. 10. Therefore, if the housing 12 is moved toward the display module 11, the size of the battery 14 is inevitably reduced in the thickness direction of the electronic device 10, and the total volume of the battery 14 is substantially unchanged only by increasing the size of the battery 14 in the length and width directions of the electronic device 10. However, in the case where the case 12 is provided in a curved shape, the increase in size of the battery 14 in the length and width directions of the electronic device 10 may structurally interfere with the case 12 (particularly, the bent portion 122). For this reason, in the embodiment of the present application, a shielding structure is disposed on a surface of the housing assembly 100 close to the display module 11 to avoid structural interference between the housing 12 and the battery 14. The avoidance structure is explained in detail below:

referring to fig. 11, fig. 11 is a schematic cross-sectional view of another embodiment of the housing assembly of fig. 5.

Since the support 17 can locally thin the edge of the housing 12, especially the side of the housing 12 close to the display module 11 (i.e. the battery 14), more space can be left for the battery 14 between the housing 12 and the middle frame 13, so that the size of the battery 14 can be increased in the length and width directions of the electronic device 10. Therefore, the supporting member 17 can be further drawn toward the flat plate portion 121 close to the housing 12, as shown in fig. 11, that is, the supporting member 17 can replace the bent portion 122 to a certain extent more, so that the supporting member 17 and the housing 12 can form an avoiding structure together.

It should be noted that, on the premise that the supporting member 17 can meet the covering requirement of the decoration 16, the size of the supporting member 17 in the length or width direction of the electronic device 10 may be further designed reasonably according to the avoidance requirement of the battery 14. Further, since the case 12 may have a four-sided curved external appearance structure, the external appearance structure of the battery 14 may be a rectangular parallelepiped. Thus, if either side of the battery 14 structurally interferes with the housing 12, the support member 17 may be in a straight line shape, based on the avoidance requirement; the support 17 can also be in the shape of a straight line, if the opposite sides of the battery 14 interfere structurally with the casing 12, except for two; the support member 17 may be L-shaped if adjacent sides of the battery 14 structurally interfere with the housing 12; if three sides of the battery 14 structurally interfere with the housing 12, the support 17 may be U-shaped, as shown in fig. 10. Of course, the support member 17 may also be square, as shown in fig. 9.

Referring to fig. 12, fig. 12 is a schematic cross-sectional view of another embodiment of the housing assembly of fig. 5.

Based on the above detailed description, in the case where the housing 12 is provided in a curved shape, the increase in size of the battery 14 in the length and width directions of the electronic device 10 may structurally interfere with the housing 12 (particularly, the bent portion 122). To this end, the second surface 124 may be partially recessed toward the first surface 123 to form an avoidance structure, such that the housing 12 can avoid the battery 14 of the electronic device 10, as shown in fig. 12. The avoiding structure is mainly used for avoiding the corners of the battery 14.

The bypass structure may also extend from the second surface 124 to the first surface 123 to extend the range of the bypass structure, thereby increasing the reliability of the bypass structure. At this time, the escape structure divides the housing 12 into the first main body portion 126 and the second main body portion 127. The first body portion 126 is far from the first end surface 125, and the second body portion 127 is close to the first end surface 125. For the electronic device 10, since the housing 12 includes the flat plate portion 121 and the bent portion 122 which are integrally formed, if the avoiding structure is just disposed at the interface between the bent portion 122 and the flat plate portion 121, the first main body portion 126 may be a partial structure of the flat plate portion 121, and the second main body portion 127 may be a partial structure of the bent portion 122; if the avoiding structure is disposed on the bent portion 122, both the first main body portion 126 and the second main body portion 127 may be partial structures of the bent portion 122.

Note that, the case 12 may have a four-sided curved external structure, and the external structure of the battery 14 may be a rectangular parallelepiped. Thus, based on the avoidance requirement, if any side of the battery 14 structurally interferes with the housing 12, the avoidance structure may be in the shape of a straight line; the avoidance structure may also be in the shape of a straight line if two opposite sides of the battery 14 structurally interfere with the housing 12, except for two; the avoidance structure may be L-shaped if adjacent sides of the battery 14 structurally interfere with the housing 12; the relief structure may be U-shaped if three sides of the battery 14 structurally interfere with the housing 12. Of course, the relief structure may also be square shaped to surround the battery 14.

Referring to fig. 13 to 15 together, fig. 13 is a schematic cross-sectional structure view of still another embodiment of the housing assembly of fig. 5, fig. 14 is a schematic cross-sectional structure view of the housing and the supporting member of fig. 13, and fig. 15 is an exploded structural view of the housing assembly of fig. 13.

Since the second surface 124 is partially recessed toward the first surface 123 to form an avoiding structure, the structural strength of the housing 12 at the avoiding structure is weakened, and there may be a risk of structural failure. For this, the supporting member 17 may be disposed between the first and

second body portions

126 and 127, as shown in fig. 12. That is, one end of the supporting member 17 is connected to the first body portion 126, and the other end of the supporting member 17 is connected to the second body portion 127, so as to connect the first body portion 126 and the second body portion 127, thereby increasing the structural strength of the housing 12.

Similarly, the supporting member 17 includes a third surface 171 and a fourth surface 172 that are oppositely disposed, the third surface 171 is on the same side as the first surface 123, and the fourth surface 172 is on the same side as the second surface 124. And the distance between the fourth surface 172 and the first surface 123 is smaller than the distance between the second surface 124 and the first surface 123 relative to the first surface 123, so that the support member 17 forms an avoiding structure together with the first main body portion 126 and the second main body portion 127. So set up, can enough realize above-mentioned dodging the demand, can increase the structural strength of casing 12 again.

It should be noted that, with respect to the first surface 123, the distance between the fourth surface 172 and the first surface 123, and the distance between the second surface 124 and the first surface 123, and the difference between the two distances can be reasonably designed according to the avoidance requirement.

For the side of the housing 12 away from the display module 11, the supporting member 17 can be embedded in the housing 12, as shown in fig. 12. At this time, the garnish 16 is attached to at least the first surface 123 and the third surface 171. Further, since the decoration 16 has a certain softness, the third surface 171 can be flush with the first surface 123, the third surface 171 can also slightly protrude from the first surface 123, and the third surface 171 can also be slightly recessed from the first surface 123. Preferably, the third surface 171 is flush with the first surface 123, so that the surface of the housing 12 and the supporting member 17 away from the display module 11 is as flat as possible. In other embodiments, the support 17 may also be embedded in the housing 12 such that the third surface 171 is covered by the first surface 123. At this time, the garnish 16 is attached to at least the first surface 123.

The first body portion 126 and the second body portion 127 may be made of plastic, and the supporting member 17 may be made of metal. For example, the metal product is made of one of stainless steel, aluminum alloy, magnesium alloy and titanium alloy. The two parts can be formed by injection molding, so that the supporting member 17, the first main body 126 and the second main body 127 form an integral structure. Further, the supporting member 17 may be partially embedded in the first main body portion 126 and the second main body portion 127 to increase the bonding strength between the supporting member 17 and the housing 12. As shown in fig. 14, a plurality of through holes 174 may be formed in the portion of the supporting member 17 embedded in the first main body portion 126 and/or the portion of the supporting member 17 embedded in the second main body portion 127, so that the supporting member 17, the first main body portion 126 and the second main body portion 127 can be engaged with each other after injection molding, thereby increasing the bonding strength between the supporting member 17 and the first main body portion 126 and further increasing the reliability of the housing assembly 100.
