It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

The inventors of the present application have found, through long-term research: at present, electronic devices (such as mobile phones) are no longer limited to existing flat panel displays, but focus more on curved displays (such as quadric screens), so that users can obtain larger display fields and better aesthetic appearance and handle feeling. Meanwhile, under the condition that the thickness of the whole mobile phone is fixed, the curved surface type display screen enables the frame of the mobile phone to be very thin, so that the arrangement of the solid keys on the frame of the mobile phone is difficult. To this end, the present application proposes the following examples.

Referring to fig. 1 to 4 together, fig. 1 is a schematic structural diagram of an embodiment of an electronic device provided in the present application, fig. 2 is a schematic structural diagram of a side view of the electronic device in fig. 1, fig. 3 is a schematic structural diagram of a rear view of the electronic device in fig. 1, and fig. 4 is a schematic structural diagram of an exploded 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 of the embodiment of the present application includes a display module 11, a rear cover plate 12, a frame 13, a rear key assembly 14, and a rear camera module 15. The display module 11 and the rear cover plate 12 are respectively connected to the frame 13, so that the display module 11 and the rear cover plate 12 form a basic structure for clamping the frame 13 together after being assembled, as shown in fig. 1 and 2. For example, the display module 11 and the rear cover plate 12 are respectively covered on two opposite sides of the frame 13 by one or a combination of assembling manners such as clamping, gluing, welding, and the like. The rear cover 12 is provided with corresponding mounting holes for mounting the rear button assembly 14 and the rear camera module 15, as shown in fig. 3 and described in detail later.

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. Generally, the display module 11 includes a display panel 111 and a transparent cover 112, and as shown in fig. 4, the transparent cover 112 is attached to the display panel 111. The display panel 111 is mainly used for displaying a picture, and is used as an interactive interface between a user and the electronic device 10; the transparent cover 112 is mainly used for protecting the display panel 111, and serves as an outer surface of the electronic device 10, so that a user can perform touch operations such as clicking, pressing, sliding and the like. In some other embodiments, the outer surface of the electronic device 10 (i.e., the surface of the transparent cover plate 112 away from the display panel 111) may further be 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 touch and visual experiences for a user.

The rear cover 12 may be a battery cover of the electronic device 10, and may be made of glass, metal, hard plastic, or other electrochromic materials. In the present embodiment, the glass cover plate is used as the back cover plate 12. An ink layer 16 may be further disposed between the rear key assembly 14 and the rear cover plate 12, as shown in fig. 3, the ink layer 16 is mainly used for shielding the rear key assembly 14, so as to prevent a partial structure of the rear key assembly 14 from being exposed to the glass cover plate, thereby increasing the aesthetic feeling of the appearance of the electronic device 10. Further, the rear cover 12 has a certain structural strength, and is mainly used to protect the electronic device 10 together with the transparent cover 112. Accordingly, the material of the frame 13 may be glass, metal, rigid plastic, or the like. The frame 13 also has a certain structural strength, and is mainly used for supporting and fixing the internal structural members of the electronic device 10, such as a battery, a main board, and a fingerprint module.

Further, since the back cover plate 12 and the frame 13 are generally directly exposed to the external environment, the material of the back cover plate 12 and the frame 13 may preferably have certain wear-resistant, corrosion-resistant, scratch-resistant, and other properties, or the outer surface of the back cover plate 12 and the frame 13 (i.e., the outer surface of the electronic device 10) may be coated with a layer of functional material for wear-resistant, corrosion-resistant, scratch-resistant. In some embodiments, the back cover plate 12 and the frame 13 may be two separate structural members, as shown in fig. 4, and they may be assembled by one or a combination of clamping, gluing, and welding. In this case, the bezel 13 may further extend into the electronic device 10, thereby forming a middle plate, a bezel, and the like. In other embodiments, the rear cover plate 12 and the frame 13 may be integrally formed, such as by hot bending, 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 rear cover 12 and the frame 13 may have a rectangular structure. The display module 11 has four sides, the back cover 12 also has four sides, and the frame 13 also has four sides accordingly. The two sides of each structural member are generally in arc transition to enhance the aesthetic appearance and the grip of the electronic device 10. Further, at least one side of at least one of the display module 11 and the rear cover 12 connected to the frame 13 is bent toward the frame 13. In other words, at least one of the four sides of the display module 11 is bent toward the frame 13; and/or at least one of the four sides of the back cover 12 is bent toward the bezel 13.

It should be noted that the side edges in the embodiments of the present application are a simple term, and the dimensions of the display module 11, the rear cover 12 and the frame 13 in the thickness direction of the electronic device 10 are not considered. Further, the side edges described in this application should not be simply understood as a general line.

In some embodiments, the four sides of the display module 11 and the four sides of the rear cover 12 may be curved toward the frame 13, as shown in fig. 1 to 4, that is, the sides may be curved, and the effect of reducing or even hiding the width of the black edge of the display module 11 is achieved by four-sided bending, so that the electronic device 10 can provide a larger display view for a user. Further, the display module 11 and the rear cover 12 may have a symmetrical structure with respect to the frame 13, as shown in fig. 2, so that the electronic device 10 can provide better aesthetic appearance and grip feeling for users. In other embodiments, the display module 11 and the rear cover 12 may have a single-curved, double-curved, or triple-curved structure, or only one of the display module 11 and the rear cover 12 may have the curved 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 back cover 12 are all four-sided curved as an example. The electronic device 10 shown in fig. 1 to 4 only describes a portion (e.g., one quarter) of the display module 11, the rear cover 12 and the frame 13, and the structures of other portions are the same as or similar to those in the drawings, and are not repeated herein.

With reference to fig. 1 to 4, the display module 11 includes a first straight portion 113 and a first curved portion 114, which are integrally formed, and the first curved portion 114 and the first straight portion 113 are in smooth transition. The rear cover plate 12 includes a second straight portion 121 and a second curved portion 122, which are integrally formed, and the second curved portion 122 and the second straight portion 121 smoothly transition. The first curved portion 114 and the second curved portion 122 are oppositely curved, that is, the curved directions of the two portions face each other. Further, the first bending portion 114 and the second bending portion 122 may be connected to two opposite surfaces of the frame 13 by one or a combination of clamping, gluing, welding, and the like.

Further, the frame 13 includes a bottom wall 131 and a side wall 132, and the side wall 132 is connected to the bottom wall 131 and extends away from the bottom wall 131. The bottom wall 131 may be regarded as a middle plate of the electronic device 10, and may be used to mount and fix the rear key assembly 14, the rear camera module 15, and other structural components such as a battery, a motherboard, and a fingerprint module in the embodiment of the present application; the side wall 132 may be partially exposed to the external environment and reinforced with the support of the bottom wall 131. The side wall 132 and the bottom wall 131 may be an integrally formed structure, that is, the frame 13 may be an integrally formed structural member, so that the structure of the frame 13 can be simplified, and the manufacturing cost of the frame 13 is reduced. Of course, in other embodiments, the side wall 132 and the bottom wall 131 can be connected by one or a combination of clamping, gluing, welding, and the like.

Referring to fig. 5 and 6 together, fig. 5 is a partially enlarged structural diagram of a portion a in fig. 1, and fig. 6 is a partially enlarged structural diagram of a portion B in fig. 4.

The bottom wall 131 includes a first bottom surface 1311 and a second bottom surface 1312 opposite to each other. The first bottom surface 1311 is close to the display module 11 and can be used for installing the display module 11, as shown in fig. 6; the second bottom surface 1312 may be used for mounting and fixing the rear key assembly 14 according to the embodiment of the application. The sidewall 132 includes a first side 1321, a second side 1322, a third side 1323, and a fourth side 1324 connected in sequence. The first side 1321 and the third side 1323 are disposed opposite to each other and are respectively used for connecting with the display module 11 and the rear cover 12, as shown in fig. 6; the second side 1322 may be exposed to the external environment. In the embodiment of the present application, the width of the second side 1322 in the thickness direction of the frame 13 is less than or equal to 1.8 mm; preferably, the width of the second side 1322 in the thickness direction of the bezel 13 is greater than or equal to 1.4mm and less than or equal to 1.6mm, so that the electronic device 10 can obtain a larger display field of view. The second side 1322 may be a straight plane or an arc convex surface, so that the electronic device 10 can provide better aesthetic appearance and hand feeling for users. Further, an edge of the first side 1321 away from the second side 1322 is connected to the first bottom surface 1311, and an edge of the fourth side 1324 away from the third side 1323 is connected to the second bottom surface 1312, as shown in fig. 6, so that the side wall 132 is connected to the bottom wall 131.

The thickness direction of the frame 13 in the embodiment of the present application refers to the overall thickness direction of the electronic device 10 when the frame 13 is applied to the electronic device 10.

Further, the width of the fourth side surface 1324 in the thickness direction of the bezel 13 is greater than the width of the second side surface 1322 in the thickness direction of the bezel 13, that is, the side wall 132 becomes thinner from the inside to the outside of the electronic device 10, as shown in fig. 6, so that the bezel 13 can meet both requirements of ultra-thinning and structural strength, thereby increasing the reliability of the bezel 13.

Because the display module 11 and the rear cover 12 may be curved structures that are curved toward the frame 13, when the display module 11 is connected to the first bottom surface 1311 and the first side surface 1321 and the rear cover 12 is connected to the third side surface 1323, an arc-shaped space is formed between the display module 11 and the rear cover 12. Therefore, the first side surface 1321 may be a curved surface having a radius of curvature the same as or similar to that of the display module 11 (specifically, the first curved portion 114), and the third side surface 1323 may also be a curved surface having a radius of curvature the same as or similar to that of the rear cover 12 (specifically, the second curved portion 122), as shown in fig. 6, so that the side wall 132 can be attached to the first curved portion 114 through the first side surface 1321 to support the display module 11, and attached to the second curved portion 122 through the third side surface 1323 to support the rear cover 12, thereby increasing the structural strength of the whole electronic device 10 and further increasing the reliability of the electronic device 10. At this time, the first side 1321 and the third side 1323 are disposed to be arc convex surfaces, the display module 11 and the back cover 12 may be bent toward the bezel 13, the display module 11 may also extend along the first side 1321, and the back cover 12 may also extend along the third side 1323. Of course, in some other embodiments, for example, when the curvature radius of the first curved portion 114 and the second curved portion 122 is larger, the first side surface 1321 and the third side surface 1323 may also be arranged in a straight plane, so as to simplify the structures of the first side surface 1321 and the third side surface 1323, thereby reducing the processing difficulty of the frame 13.

In the embodiment of the present application, the first side 1321 is recessed toward a direction close to the third side 1323 to form a first groove 1325, the third side 1323 is recessed toward a direction close to the first side 1321 to form a second groove 1326, a distance between the second groove 1326 and the first groove 1325 is smaller than a width of the second side 1322 in the thickness direction of the bezel 13, as shown in fig. 6, so that the display module 11 can extend to the first groove 1325 along the first side 1321, and the back cover 12 can extend to the second groove 1326 along the third side 1323, as shown in fig. 5, so that the display module 11 and the back cover 12 can be partially hidden in the side wall 132, that is, the bezel 13 can protect edges of the display module 11 and the back cover 12 to a certain extent, and further increase reliability of the electronic device 10.

Based on the above detailed description, under the condition that the overall thickness of the electronic device 10 is constant, the curved structures of the display module 11 and the rear cover 12 may severely compress the thickness of the frame 13, so that the frame 13 becomes at least partially thin, as shown in fig. 1 to 6, which makes it difficult to set physical keys on the frame 13 according to the related art. Therefore, the application develops a new way to carry out post-design on the entity keys such as the power key, the volume key and the AI key which are originally arranged on the frame 13 in the related technology, so that the user can carry out corresponding pressing operation on one side of the back cover plate 12. That is, the mounting hole 123 is formed in the rear cover plate 12, the rear key assembly 14 is disposed on one side of the rear cover plate 12 close to the display module 11, and the rear key assembly 14 receives the touch pressing force through the mounting hole 123, so as to consider the ultra-thinning of the frame 13 and the requirement for setting the physical keys, thereby meeting the requirement of the curved surface structures of the display module 11 and the rear cover plate 12 for the space. The mounting hole 123 may be circular, elliptical, oblong, rectangular with rounded corners, or the like in shape; the geometric dimensions of the mounting hole 123 can be designed reasonably according to the pressing requirements of the rear key assembly 14 and the aesthetic appearance of the electronic device 10. The specific structure of the rear key assembly 14 and its cooperation with the rear cover 12 will be described in detail below.

Referring to fig. 7 and 8 together, fig. 7 is a schematic cross-sectional view of the electronic device in fig. 1 along direction VII-VII, and fig. 8 is an exploded schematic view of the rear key assembly in fig. 4.

The rear button assembly 14 includes a bracket 141, a rear button 142 and a touch-sensing element 143, as shown in fig. 8. The rear button 142 is disposed on a side of the rear cover 12 close to the display module 11 and receives a touch pressing force through the mounting hole 123, and the touch device 143 is disposed on a side of the rear button 142 close to the display module 11, as shown in fig. 7. The bracket 141 is disposed on a side of the rear cover 12 close to the display module 11 and is used for supporting the rear button 142 and the touch device 143, for example, the bracket 141 is fixed to the rear cover 12 and/or the frame 13 (specifically, the bottom wall 131) so that the touch device 143 can be triggered under the action of the touch pressing force.

It should be noted that the touch pressing force in the embodiment of the present application refers to an acting force required by the user to press the rear button 142 on the side of the rear cover 12 to trigger the touch element 143. Further, the rear button 142 may be a power key, which is matched with the corresponding touch control element 143, so as to enable the electronic device 10 to be turned on or off under the action of the touch control pressing force; the rear button 142 may also be a volume button, which cooperates with the corresponding touch control element 143 to adjust the volume of the electronic device 10 under the action of the touch control pressing force; the rear button 142 may also be an AI button, which cooperates with the corresponding touch-sensing element 143 to open an AI function of the electronic device 10 under the action of the touch-sensing pressing force.

The bracket 141 includes a bearing portion 1411 and a separating portion 1412, as shown in fig. 8; the separating portion 1412 and the supporting portion 1411 may be an integrally formed structural member, and both may form an accommodating space (not labeled) for accommodating the touch device 143 and the rear button 142. Wherein, the carrying part 1411 is arranged opposite to the back cover plate 12, as shown in fig. 7; the supporting portion 1411 can be fixed on the bottom wall 131, so that the bracket 141 supports the rear button 142 and the touch device 143. The isolating portion 1412 is connected to the carrying portion 1411 and extends toward a direction away from the display module 11, as shown in fig. 7; the partition 1412 may be fixed to the rear cover 12 so that the support 141 supports the rear buttons 142 and the touch sensing element 143. The touch device 143 is disposed on the supporting portion 1411, for example, the touch device 143 is fixed on a surface of the supporting portion 1411 away from the display module 11 by one of the connection manners of clamping, gluing, and fastening with screws, or a combination thereof, as shown in fig. 7.

Further, a notch 1413 is formed at a connection portion of the separating portion 1412 and the carrying portion 1411, and as shown in fig. 7, the notch 1413 may be formed only in one of the carrying portion 1411 and the separating portion 1412. The notch 1413 is mainly used for facilitating the wiring of the touch device 143, so as to facilitate the signal transmission between the touch device 143 and a control unit (not shown in the figure) such as a motherboard of the electronic device 10. That is, when the touch device 143 is disposed on the supporting portion 1411, the touch device 143 can extend from one side of the bracket 141 away from the display module 11 to the other side of the bracket 141 close to the display module 11 through the notch 1413, as shown in fig. 7.

The rear button 142 includes an operation portion 1421 and a guide portion 1422, as shown in fig. 8; the guide part 1422 and the operating part 1421 may be an integrally formed structural member. Wherein, the operation part 1421 is disposed opposite to the mounting hole 123, as shown in fig. 7; the operation portion 1421 is configured to receive a touch pressing force, that is, the operation portion 1421 is used as a force point when the user presses the rear button 142. The guide part 1422 is connected to the operation part 1421 and extends toward the direction close to the partition 1412, and the guide part 1422 mainly guides the user in the process of pressing the rear button 142. The arrangement is such that the rear button 142 can move along the partition 1412 toward the direction close to the display module 11 under the action of the touch pressing force, so as to trigger the touch element 143. Wherein, can be clearance fit between guide 1422 and the isolation 1412, for example, the fit clearance between the two is 0.1mm, not only can increase the stationarity that rear key 142 removed for support 141, can also play waterproof dirt-proof effect to a certain extent to increase rear key assembly 14's reliability.

Further, the operation portion 1421 includes a pressing surface 1423 and a touch surface 1424, as shown in fig. 7. The pressing surface 1423 may protrude from the guide portion 1422 and may be recessed or flush with a surface of the rear cover 12 away from the display module 11. So set up to make operation portion 1421 partially wear to locate mounting hole 123, and receive the touch-control pressing force through pressing surface 1423, not only can make things convenient for the user to press rear key 142, can also avoid the user to miss rear key 142, thereby increase rear key assembly 14's reliability. Further, the pressing surface 1423 is the same or similar to the mounting hole 123 in external shape, for example, the pressing surface 1423 and the mounting hole 123 are both circular, elliptical, oblong, rectangular with rounded corners, or the like in external shape. Also, a fitting clearance between the operation part 1421 and the mounting hole 123 may be smaller than or equal to a fitting clearance between the guide part 1422 and the spacer 1412, for example, a fitting clearance between the operation part 1421 and the mounting hole 123 is 0.05 mm. With such an arrangement, on one hand, the bracket 141 and the rear cover plate 12 can guide the rear key 142 at the same time, so that the moving stability of the rear key 142 relative to the bracket 141 is further increased, the waterproof and dustproof performance of the rear key assembly 14 is increased to a certain extent, and the reliability of the rear key assembly 14 is further increased; on the other hand, the rear key 142 can be adapted to the rear cover 12, thereby increasing the aesthetic appearance of the electronic device 10. Further, the touch surface 1424 may also protrude from the guide portion 1422, and the touch surface 1424 may also contact the touch element 143 to trigger the touch element 143 under the action of the touch pressing force. With this arrangement, not only the structural compactness of the rear key assembly 14 can be increased, but also the local part of the rear key 142 can be thinned, so as to reduce the overall weight of the rear key assembly 14. Of course, in other embodiments, the pressing surface 1423 and/or the touch surface 1424 may be flush with the guide portion 1422, so that the rear key 142 is disposed in a flat plate shape in the whole structure, thereby increasing the compactness of the rear key assembly 14 in the structure and reducing the whole weight of the rear key assembly 14.

Based on the above detailed description, the touch device 143 can be a key switch with a certain key stroke, that is, the touch device 143 is triggered after the rear key 142 moves a certain distance (e.g. 0.2mm) relative to the bracket 141 under the action of the touch pressing force. The touch element 143 may also be a pressure sensitive device, in which a piezoelectric film may be disposed. Based on the characteristic that the piezoelectric film is generally very sensitive to stress strain, for example, the sensitivity of a polyvinylidene fluoride (PVDF) polymer film with a thickness of 28 μm is typically 10 to 15 mV/microstrain, the touch element 143 can be triggered as long as the rear key 142 moves slightly (e.g., 0.05mm) relative to the support 141.

Further, the rear key assembly 14 further includes a first sealing member 144 and a second sealing member 145, as shown in fig. 7. The first seal 144 is disposed between the partition 1412 and the rear cover plate 12 such that the bracket 141 and the rear cover plate 12 form a sealing structure at the junction thereof. The second sealing member 145 is disposed on a side of the bracket 141 close to the display module 11 and along the notch 1413, so that after the touch device 143 is wired through the notch 1413, the second sealing member 145 can seal the bracket 141 and the touch device 143. With this arrangement, the accommodating space formed by the bracket 141 and other spaces inside the electronic device 10 are isolated from each other, so that moisture, dust, and the like in the external environment are prevented from invading the electronic device 10 through the gaps between the bracket 141 and the rear cover 12 and the touch element 143, and the waterproof and dustproof performance of the electronic device 10 is further improved. The first sealing element 144 may be one or a combination of structures such as foam, glue, rubber ring, and silicone sleeve, and the second sealing element 145 may be one or a combination of structures such as foam, glue, and PET (Polyethylene Terephthalate) waterproof film. Of course, in other embodiments, a sealing member such as a rubber ring or a silicone sleeve may be disposed between the guide part 1422 and the rear cover 12 to further increase the waterproof and dustproof performance of the electronic device 10.

Further, the ink layer 16 is disposed between the rear key 142, the first sealing element 144 and the rear cover 12, as shown in fig. 3, so as to prevent structural members such as the rear key 142 and the first sealing element 144 from being exposed to the rear cover 12 (e.g., a glass cover), or prevent contact indentations (especially the first sealing element 144) from occurring when the structural members are engaged with the rear cover 12, thereby increasing the aesthetic appearance of the electronic device 10. However, since the ink layer 16 is thin, although the schematic cross-sectional structure (for example, fig. 7) of the present application does not show the ink layer 16, it cannot be simply considered that it is not present.

Referring to fig. 9, fig. 9 is a schematic cross-sectional structure view of another embodiment of the rear button assembly in fig. 8.

The bracket 141 further includes a stopping portion 1414, the stopping portion 1414 is connected to the carrying portion 1411 and extends toward a direction away from the display module 11, and the stopping portion 1414 is used for stopping the guiding portion 1422. The stopping portion 1414, the separating portion 1412 and the carrying portion 1411 may also be integrally formed structural members. Further, since the operating portion 1421 may protrude from the guiding portion 1422, the height of the stopping portion 1414 in the pressing direction of the rear key assembly 14 may be greater than or equal to the thickness of the touch element 143, so that the operating portion 1421 can trigger the touch element 143 under the effect of the touch pressing force. In addition, in the process that the rear button 142 moves towards the touch device 143 relative to the bracket 141, the stopping portion 1414 can also stop the guiding portion 1422 to limit the moving distance of the rear button 142 relative to the bracket 141, so as to prevent the rear button 142 from crushing the touch device 143, thereby increasing the reliability of the rear button assembly 14.

It should be noted that, in the pressing direction of the rear key assembly 14, the height of the stopping portion 1414 and the distance between the stopping portion 1414 and the guiding portion 1422 can be reasonably designed according to the above-mentioned triggering and limiting requirements, and the like, and are not limited herein.

In some embodiments, the stopping portion 1414 may be disposed around the touch sensing element 143, that is, the stopping portion 1414 and the carrying portion 1411 may enclose an accommodating space (not labeled in the figures) for accommodating the touch sensing element 143. Further, the stopping portion 1414 and the separating wall 1412 may be disposed adjacent to each other, so that the stopping portion 1414, the separating wall 1412 and the carrying portion 1411 may enclose a relatively independent accommodating space 1415, as shown in fig. 9. When moisture, dust, etc. in the external environment intrude into the rear key assembly 14 along the gap between the rear key 142 and the rear cover 12, the accommodating space 1415 may be used to collect the moisture, dust, etc. to prevent them from further eroding the touch element 143, thereby increasing the reliability of the rear key assembly 14. Of course, in other embodiments, some fillers such as drying agent may be pre-disposed in the accommodating space 1415.

Further, other structures in this embodiment can refer to the above detailed description, and are not repeated herein.

Referring to fig. 10, fig. 10 is a schematic cross-sectional structure diagram of another embodiment of the rear key assembly in fig. 8.

The rear key assembly 14 further includes an elastic member 146, and the elastic member 146 is disposed between the supporting portion 1411 and the guiding portion 1422, and specifically, may be disposed in the accommodating space 1415, as shown in fig. 10. Further, the elastic member 146 is mainly used for elastically supporting the rear button 142, so that the guide portion 1422 abuts against the rear cover 12, thereby increasing the waterproof and dustproof performance of the electronic device 10, and also increasing the pressing smoothness of the rear button 142. The elastic member 146 may be a spring, rubber, or silicon rubber. The present application will be described with reference to the elastic member 146 as a spring. In some embodiments, the number of the elastic members 146 may be one, and one elastic member 146 is sleeved on the stopping portion 1414 to elastically support the rear key 142. In other embodiments, the number of the elastic members 146 may be multiple, and the elastic members 146 may be uniformly wound around the stopping portion 1414 and also elastically support the rear key 142. For example: the number of the elastic members 146 is six, and the six elastic members 146 are uniformly distributed around the stopping portion 1414 at intervals of 60 ° in pairs.

Further, the pressing surface 1423 may also protrude from a surface of the rear cover 12 away from the display module 11, and is mainly used for supporting the electronic device 10 and preventing the camera module 15 (e.g., a protective cover of a lens) from being scratched by a foreign object (e.g., when the electronic device 10 is placed on a desk), so as to increase the reliability of the electronic device 10. In this case, the pressing surface 1423 may be disposed in a spherical surface to increase the smoothness of the portion of the rear key 142 exposed to the rear cover 12, thereby increasing the aesthetic appearance of the electronic device 10. The part of the rear key 142 exposed out of the rear cover plate 12 is preferably made of a material with certain wear-resistant, corrosion-resistant, scratch-resistant and other properties; alternatively, the pressing surface 1423 is coated with a layer of wear-resistant, corrosion-resistant, and scratch-resistant functional material. Furthermore, the elastic member 146 supports the rear button 142 with an elastic force greater than or equal to the weight of the electronic device 10, that is, when the electronic device 10 is placed on a supporting body such as a desktop, the rear button 142 will not move relative to the bracket 141 and trigger the touch device 143 due to the weight of the electronic device 10, so as to prevent the rear button assembly 14 from mistakenly triggering the touch device 143, thereby increasing the reliability of the rear button assembly 14.

It should be noted that the height of the rear key 142 exposed out of the rear cover 12 can be reasonably designed according to factors such as the scratch-resistant requirement of the camera module 15, and is not limited herein. Furthermore, the elastic force of the elastic member 146 supporting the rear button 142 can be reasonably designed according to the self weight of the electronic device 10 and the touch requirement of the touch device 143, and the like, which is not limited herein.

Referring to fig. 7 to 10 again, the rear button 142 may be further fixed to a surface of the rear cover 12 close to the display module 11 and cover the mounting hole 123. For example: the guiding portion 1422 (i.e., the fixing portion) can be fixed to the rear cover 12 by one or a combination of assembling manners such as clamping, gluing, welding, and the like, and the pressing portion 1421 is disposed opposite to the mounting hole 123. Further, the touch device 143 contacts the rear button 142, so that the rear button 142 can elastically deform toward a direction close to the display module 11 under the action of the touch pressing force, and the touch device 143 can be triggered. At this time, the touch element 143 may be a pressure sensitive device in which a piezoelectric film may be disposed. Based on the characteristic that the piezoelectric film is generally very sensitive to stress strain, for example, the typical value of the sensitivity of a polyvinylidene fluoride (PVDF) polymer film with a thickness of 28 μm is 10 to 15 mV/microstrain, the touch device 143 can be triggered as long as the pressing portion 1421 of the rear key 142 generates a small deformation relative to the guiding portion 1422. The arrangement is such that the key stroke of the rear key 142 is reduced, so as to reduce the size of the rear key assembly 14 in the thickness direction of the electronic device 10 to a certain extent, so as to facilitate the electronic device 10 to be light and thin.

It should be noted that the parameters of the rear button 142, such as material and thickness, can be reasonably designed according to the touch requirement of the touch element 13 and the sensitivity thereof, and are not limited herein.

The above description is only a part of the embodiments of the present application, and not intended to limit the scope of the present application, and all equivalent devices or equivalent processes performed by the content of the present application and the attached drawings, or directly or indirectly applied to other related technical fields, are also included in the scope of the present application.
