Description

Technical Field

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

[0002] Electronic devices have gradually become one of the devices that people often use in their daily lives or work. Electronic devices are usually equipped with physical key structures. At present, with the advancement of thinness and lightness of electronic devices such as mobile phones and tablets, the thickness of the entire machine is getting thinner and thinner, while the feel of the key structure must be guaranteed. As a result, the thickness of the key structure has increased relatively, resulting in a smaller width of the beam around the key structure of the outer frame of the electronic device's shell, which makes the connection area between the shell and the internal structure smaller. Not only is the connection strength insufficient, but the shell also has a high risk of deformation. This problem needs to be solved urgently. Summary of the invention

[0003] The present application provides an electronic device, wherein the connection area between the housing and the support member of the electronic device is large, the connection strength between the housing and the support member is large, the overall stability of the housing and the support member is strong, and the deformation risk of the housing can be reduced.

[0004] To achieve the above objectives, the embodiments of the present application adopt the following technical solutions: In a first aspect, the present application provides an electronic device, which includes an outer frame, a connector, a support member, and a key structure, wherein a first through hole is provided on the outer frame. The connector includes a connecting body and an extension portion, wherein the connecting body is fixed to the outer frame and is located on the outer peripheral side of the first through hole. Specifically, the orthographic projection of the connecting body on the reference plane does not overlap with the orthographic projection of the first through hole on the reference plane. Exemplarily, the connecting body may be located between the outer frame and the inner frame.

[0005] In this way, the connecting member can be fixed to the outer frame through the connecting body, so that the connection between the connecting body and the outer frame becomes convenient, and further the connection operation between the connecting member and the shell becomes convenient.

[0006] The extension portion is fixed to the connection body, and the orthographic projection of the extension portion on the reference plane partially overlaps with the orthographic projection of the first through hole on the reference plane, and the reference plane is perpendicular to the axial direction of the first through hole.

[0007] The support member is located on the inner side of the outer frame, a second through hole is opened on the support member, the second through hole is opposite to and connected with the first through hole, and the support member is fixed to the connecting body and the extension portion. The key structure is penetrated through the first through hole and the second through hole, and the key structure can move relative to the outer frame along the axial direction of the first through hole.

[0008] In the electronic device according to the embodiment of the present application, the orthographic projection of the extension portion on the reference plane partially overlaps with the orthographic projection of the first through hole on the reference plane, indicating that the extension portion does not completely block the first through hole, so as to ensure the normal movement of the key structure.

[0009] Among them, the orthographic projection of the extension portion on the reference plane partially overlaps with the orthographic projection of the first through hole on the reference plane, indicating that the extension portion does not completely block the first through hole, so as to ensure the normal movement of the key structure.

[0010] In addition, the part of the support member facing the cross beam can be directly connected to the housing, or the part of the support member facing the cross beam can also be connected to the housing by means of a connecting member; and the part of the support member facing the extension portion can be connected to the housing by means of the extension portion. In this way, the connection width of the support member and the housing in the width direction of the outer frame is increased, thereby increasing the connection area between the support member and the housing, and further increasing the connection strength between the support member and the housing, so as to enhance the overall stability of the housing and the support member. Especially, the connection strength between the area around the first through hole on the outer frame and the connecting member is increased. When the electronic device falls or is collided, the housing is not easily deformed.

[0011] Therefore, when the overall thickness of the electronic device is made thinner, the thickness of the key structure can be relatively increased. By providing the above-mentioned connecting member on the housing to be connected to the support member, while ensuring the connection strength between the housing and the support member and reducing the risk of housing deformation, the function of the key structure is also realized, enhancing the user experience.

[0012] In some embodiments provided in the first aspect of the present application, at least a part of the extension portion protrudes from the inner wall surface of the first through hole in the width direction of the outer frame.

[0013] In this way, it is beneficial to increase the connection width of the support member and the outer frame in the width direction of the outer frame, thereby being beneficial to increasing the connection area between the support member and the outer frame, and further enhancing the reliability of the connection between the support member and the outer frame. Especially, the connection strength between the cross beam on the outer frame and the support member is increased, and the support member and the housing are not easily separated. When the electronic device falls or the cross beam is collided, the cross beam is not easily deformed, and the normal function of the key structure can be ensured.

[0014] Moreover, the sum of the dimensions of the cross beam and / or the connection body on the outer periphery of the through hole and the extension portion in the Z-axis direction is relatively large, and the connection width of the support member and the housing in the Z-axis direction is increased. When the connecting member and the support member are bonded by an adhesive layer, it is more convenient to apply glue, and the glue injection needle does not need to be made too large. It can be understood that the smaller the glue injection needle is made, the higher the cost. Therefore, the extension portion protruding from the inner wall surface of the first through hole in the width direction of the outer frame can also reduce the difficulty of applying glue and save costs at the same time.

[0015] In some embodiments provided in the first aspect of the present application, a clearance notch is formed on the key structure, and a part of the extension part is located in the clearance notch. The clearance notch can avoid the extension part, which can not only increase the connection area between the support member and the shell, and enhance the connection strength between the shell and the support member, but also help to avoid the connection member hindering the normal movement of the key structure, thereby ensuring the function of the key structure.

[0016] In some embodiments provided in the first aspect of the present application, the outer frame includes a first beam and a second beam located on opposite sides of the first through hole, and the first beam and the second beam are arranged in the width direction of the outer frame; the connecting body is fixed to at least one of the first beam and the second beam. In this way, the overall structural strength of the connecting body, the first beam and the second beam is relatively large, and has high stability. In the case of the electronic device falling or being hit, the risk of deformation at the first beam and the second beam can be further reduced, and the function of the key structure can be better guaranteed.

[0017] Moreover, the sum of the dimensions of the connecting body and the extension part in the Z-axis direction is further increased, and the connection width between the support member and the shell in the Z-axis direction is also further increased. When the connecting member and the support member are bonded by the adhesive layer, glue dispensing can be more convenient, which can further reduce the difficulty of glue dispensing and save costs.

[0018] In some embodiments provided in the first aspect of the present application, the connecting body has an avoidance hole, the avoidance hole is opposite to and connected to the first through hole, and the key structure is passed through the avoidance hole. By setting the avoidance hole, it is possible to avoid the connecting member hindering the movement of the key, thereby ensuring the key function. In addition, the connecting body can be formed into a ring shape, which can further increase the connection area between the connecting member and the housing, and can also increase the connection area between the connecting member and the support member, further increase the connection strength of the housing, the connecting member and the support member as a whole, and better ensure the stability of the overall structure of the housing, the connecting member and the support member.

[0019] In some embodiments provided in the first aspect of the present application, a first groove is formed on the end surface of the support member facing the outer frame, and the connecting body and the extension portion are both fixed to the groove wall surface of the first groove. In this way, the stacking size of the support member, the connecting member and the adhesive layer can be reduced, making the overall structure of the connecting member and the support member more compact, which is conducive to the lightweight design of the electronic device. The connecting body and the extension portion are fixed in the first groove, which also makes the connection between the connecting member and the support member more tightly, which helps to enhance the connection strength between the connecting member and the support member.

[0020] In some embodiments provided in the first aspect of the present application, the connecting member further includes a connecting flange, the connecting flange is fixed to the connecting body, and the connecting flange is bent relative to the connecting body in a direction away from the outer frame. The connecting flange is located on the side of the connecting body facing away from the housing, which facilitates the connection between the connecting flange and the support member. And it can further increase the connection area between the connecting member and the support member, thereby increasing the connection area between the housing, the connecting member as a whole and the support member, and further enhancing the connection strength between the housing and the support member, so as to increase the stability of the overall connection between the housing and the support member. When the electronic device drops or is impacted, it is not easy for the housing and the support member to separate, and further reduces the risk of housing deformation.

[0021] The connecting flange includes a first connecting surface, the support member includes a second connecting surface, the first connecting surface is connected to the second connecting surface and the first connecting surface and the second connecting surface are opposite in a first direction, and the first direction is perpendicular to the axial direction of the first through hole. This makes it more convenient to connect the connecting flange and the support member, and further makes the connection operation between the connecting member and the support member convenient. The support member can be connected to the housing by means of the connecting flange, which further increases the connection area between the support member and the housing and increases the connection strength between the support member and the housing.

[0023] In some embodiments provided in the first aspect of the present application, the inner wall surface of the second through hole includes a second connecting surface. In this way, at least a part of the connecting flange extends into the second through hole, the connecting flange and the inner wall of the second through hole are opposite in the first direction, and the connecting flange is connected to the inner wall of the second through hole.

[0024] It should be noted that there is a certain distance between the connecting flange extending into the second through hole and the key structure to ensure that the connecting flange does not affect the movement of the key structure.

[0025] The connecting flange of the connecting member is connected to the inner wall of the second through hole, so that the connecting member can be connected to the supporting member, enhancing the connection strength between the connecting member and the supporting member, and thus enhancing the connection strength between the housing and the supporting member. Moreover, it can be understood that the connecting flange is located on the outer peripheral side of the key structure, so the connecting flange is adjacent to the cross beam on the outer peripheral side of the first through hole, which can better enhance the connection strength between the cross beam and the connecting member. When the electronic device drops or is impacted, the risk of deformation of the housing when the electronic device drops or is impacted can be further reduced, the cross beam is not easily deformed, and the function of the key structure can be ensured.

In this way, at least part of the connecting flange can be accommodated in the second groove; alternatively, if the connecting flange is not accommodated in the second groove, at least part of the connection structure (such as an adhesive layer) between the connecting body and the supporting member can be accommodated in the second groove. Both of these make the overall structure of the connecting member and the supporting member more compact, contributing to the thin and light design of the electronic device.

[0027] In some embodiments provided in the first aspect of the present application, one of the supporting member and the housing can be a plastic part, and the other of the housing and the supporting member can be a metal part. When one of the housing and the supporting member is a metal part, the overall structural strength of the housing and the supporting member can be enhanced; the cost of the plastic part is relatively low and the density is small. When one of the housing and the supporting member is a plastic part, the overall processing cost of the electronic device can be reduced, and the overall weight of the electronic device can be reduced, contributing to the lightweight design of the electronic device.

[0029] In some embodiments provided in the first aspect of the present application, the connecting member and the supporting member are bonded through an adhesive layer. The adhesive layer has good bonding performance, can realize reliable bonding between the connecting member and the supporting member. At the same time, the adhesive layer has good waterproof and oil-resistant properties. The setting of the adhesive layer can improve the sealing performance between the connecting member and the supporting member, thereby improving the waterproof and oil-proof protection performance of the electronic device.

[0030] In some embodiments provided in the first aspect of the present application, a glue-blocking protrusion is formed on the end surface of the support member facing the outer frame, and the glue-blocking protrusion is located on the side of the extension portion close to the key structure. In this way, the glue-blocking protrusion can separate the adhesive layer and the key structure, thereby reducing the risk of the glue in the adhesive layer seeping onto the key structure, preventing the key structure from being stuck, and being beneficial to ensuring the function of the key structure.

The key structure passes through the first through hole and the second through hole, and the key structure can move axially along the first through hole relative to the outer frame.

[0034] The connecting member includes a connecting main body and a connecting flange. The connecting main body is fixed to the outer frame and is located on the outer peripheral side of the first through hole. Specifically, the orthographic projection of the connecting main body on the reference plane does not overlap with the orthographic projection of the first through hole on the reference plane.

[0060] The housing assembly 1a is used to protect the internal electronic components of the electronic device 100 and can be used to support the screen 7. Please refer to Figure 3 and Figure 4 , Figure 3 is Figure 1 the exploded view of the electronic device 100 shown in . The housing assembly 1a includes a housing 1 and a support member 3. The material of the housing 1 includes but is not limited to metal, ceramic, plastic, and glass. The housing 1 has a receiving space 10. Exemplarily, the housing 1 may include a back cover 12 and an outer frame 11.

[0061] Please continue to refer to Figure 3 and Figure 4 , the back cover 12 can be in a flat shape, the outer frame 11 can be fixed to the edge of the back cover 12, and the outer frame 11 and the back cover 12 can enclose the above-mentioned receiving space 10. Exemplarily, the outer frame 11 can be fixedly connected to the back cover 12 by adhesive. Or, the outer frame 11 and the back cover 12 can also be an integrally formed structure, that is, the outer frame 11 and the back cover 12 are a whole structure.

[0062] In some embodiments, the outer frame 11 is annular. Exemplarily, the outer frame 11 can be rectangular-annular. In some other embodiments, the outer frame 11 can also be non-annular. In this case, the outer frame 11 can be provided only on one side, two sides or three sides of the back cover 12.

[0063] The support member 3 serves as the structural "skeleton" of the electronic device 100, and is used to support and fix the electronic components within the electronic device 100.

[0064] Referring to Figure 4 , the support member 3 is located within the accommodation space 10. The support member 3 is located inside the outer frame 11, and the support member 3 can be fixedly connected to the inner surface of the outer frame 11. Herein, the "inner surface" described in the embodiments of the present application refers to the surface of the component facing the inside of the housing 1. Correspondingly, the "outer surface" described in the embodiments of the present application refers to the surface of the component facing the outside of the housing 1. When observing from the outside of the electronic device 100, the inner surface of the outer frame 11 is in an invisible state.

[0065] The support member 3 includes an inner frame 30 and a bottom plate 35. Exemplarily, the inner frame 30 can be fixedly connected to the bottom plate 35 by adhesive. Alternatively, the inner frame 30 and the bottom plate 35 can also be an integrally formed structure, that is, the inner frame 30 and the bottom plate 35 are a single integral structure. Among them, the bottom plate 35 and the back cover 12 are stacked in the Z-axis direction. For example, the bottom plate 35 and the back cover 12 can be spaced apart or connected in the Z-axis direction.

[0066] Please continue to refer to Figure 3 and Figure 4 , the bottom plate 35 can be in a flat plate shape, and the inner frame 30 can be fixed to the edge of the bottom plate 35. Exemplarily, the inner frame 30 can be fixedly connected to the bottom plate 35 by adhesive. Alternatively, the inner frame 30 and the bottom plate 35 can also be an integrally formed structure, that is, the inner frame 30 and the bottom plate 35 are a single integral structure.

[0067] In some embodiments, the inner frame 30 is annular. The shape of the inner frame 30 can be the same as the shape of the outer frame 11. Exemplarily, the inner frame 30 can be rectangular-annular. In some other embodiments, the outer frame 11 can also be non-annular. In this case, the outer frame 11 can be provided only on one side, two sides or three sides of the back cover 12.

[0068] Exemplarily, please refer to Figure 4 , the screen 7 can be supported and fixed on the inner frame 30 of the support member 3, and the screen 7 and the bottom plate 35 are spaced apart in the Z-axis direction. In some other embodiments of the present application, the support member 3 may not include the bottom plate 35.

[0069] According to some embodiments of the present application, one of the support member 3 and the housing 1 may be a plastic part, and the other of the housing 1 and the support member 3 may be a metal part. For example, the material of the metal part may include at least one of aluminum, aluminum alloy, titanium, and titanium alloy. When one of the housing 1 and the support member 3 is a metal part, the overall structural strength of the housing 1 and the support member 3 can be enhanced; the cost of the plastic part is low and the density is small. When one of the housing 1 and the support member 3 is a plastic part, the overall processing cost of the electronic device 100 can be reduced, and the overall weight of the electronic device 100 can be reduced, which helps the lightweight design of the electronic device 100.

[0070] For example, the housing 1 may be a metal part and the support member 3 may be a plastic part. In this way, when the electronic device 100 is subjected to stress impacts such as collision and extrusion, the housing 1 has a large stiffness to resist deformation. The support member 3 is located on the inner surface of the housing 1. The support member 3 can play a role in supporting the housing 1, and at the same time ensure the protection of the internal structural parts by the overall housing 1 and the support member 3.

[0071] For another example, the housing 1 may be a plastic part and the support member 3 may be a metal part. In this way, when the electronic device 100 is subjected to stress impacts such as collision and extrusion, the support member 3 has a large stiffness to resist deformation, and the support member 3 is located on the inner surface of the housing 1. The support member 3 can play a role in supporting the housing 1, and at the same time ensure the protection of the internal structural parts by the overall housing 1 and the support member 3. The housing 1 being a plastic part helps to reduce the processing cost of the electronic device 100 and helps the lightweight design of the electronic device 100.

[0072] In the embodiments of the present application, the case where the housing 1 is a metal part and the support member 3 is a plastic part is taken as an example for illustration. However, this should not be construed as a limitation to the present application.

[0073] Refer to Figure 1 , the main board 8 is used to integrate electronic components. Exemplarily, the electronic components may include at least one of a processor (which may also be called a chip), an antenna module, a Bluetooth module, a WiFi module, a GPS module, a charging module, or a screen display and operation module, a resistor, a capacitor, an inductor, a potentiometer, an electron tube, an electromechanical component, a connector, a semiconductor discrete device, a sensor, a power supply, a switch, a micro special motor, an electronic transformer, a relay, and a universal serial bus (USB) device.

[0074] The button module 20 can be used to trigger one or more functions of the electronic device 100. The button module 20 can be electrically connected to the main board 8 of the electronic device 100. Exemplarily, the button module 20 can include at least one of a volume adjustment key and a power key. In this way, operations such as volume adjustment, power on / off, screen locking, unlocking, waking up, and camera control of the electronic device 100 can be performed through the button module 20.

[0075] The button module 20 includes a button structure 2 and a switch component 60. The switch component 60 can be disposed in the accommodation space 10 and is located on a side of the inner frame 30 away from the outer frame 11. In some embodiments, the switch component 60 includes a button circuit board 61 and a switch 6. The button circuit board 61 is electrically connected to the main board 8 of the electronic device 100. The button circuit board 61 can be a flexible circuit board, a rigid circuit board, or a rigid-flex circuit board. The switch 6 can be electrically connected to the surface of the button circuit board 61 facing the button structure 2. Exemplarily, the switch 6 can be a dome switch.

[0076] The button structure 2 is used to cooperate with the switch 6 to trigger corresponding functions of the electronic device 100. The number of the button structures 2 can be one or more, and the present application does not limit the number of the button structures 2. Figure 1 Only an example is given in which the number of the button structures 2 is two, and the two button structures 2 are arranged at intervals along the Y-axis direction as side keys, which should not be considered as a special limitation to the present application. In Figure 1 the illustrated embodiment, among the two button structures 2, one button structure 2 can be a volume key, and the other button structure 2 can be a power key.

[0077] The button structure 2 can be disposed on the housing assembly 1a. In some embodiments, please refer to Figure 4 and Figure 5 , Figure 5 which is Figure 3 an enlarged view of the circled part at B in

[0078] In some embodiments, the outer frame 11 includes a cross beam, and the cross beam includes a first cross beam 111 and a second cross beam 112 located on opposite sides of the first through hole 110. The first cross beam 111 and the second cross beam 112 are in the width direction of the outer frame 11 (for example, refer to Figure 4arranged in the Z-axis direction). The crossbeam refers to the structure between the inner wall of the first through hole 110 and the end face of the outer frame 11 in the width direction of the outer frame.

[0079] Please refer to Figure 6 , Figure 6 which is a schematic structural diagram of the key structure 2 of the electronic device 100 according to some embodiments of the present application; the key structure 2 includes a key body 22, a limit hook 25 and a trigger member 24.

[0080] Exemplarily, the key body 22 may be strip-shaped. The key body 22 has an appearance surface 221, and the appearance surface 221 is exposed outside the first through hole 110. The appearance surface 221 can be used to contact the user's finger, so that the user can apply a pressing force to the key structure 2 through the appearance surface 221.

[0081] The trigger member 24 is located on the side of the key body 22 opposite to the appearance surface 221. Specifically, the trigger member 24 is located between the key body 22 and the switch member 6. The trigger member 24 can be rod-shaped or block-shaped. The trigger member 24 is at least one. When there are two or more trigger members 24, the plurality of trigger members 24 can be arranged at intervals in the Y-axis direction. Figure 5 Only an example is given where the number of trigger members 24 is two, and the two trigger members 24 are arranged at intervals in the Y-axis direction, which should not be considered as a special limitation to the present application.

[0082] When the user presses the key body 22, the key body 22 drives the trigger member 24 to move towards the dome sheet and squeeze the dome sheet. At the same time, the user needs to overcome the acting force of the dome sheet on the key structure 2 to force the dome sheet to deform, so that the dome sheet contacts the circuit on the key circuit board 61, thereby conducting to form a loop to achieve signal transmission. After the acting force applied by the user to the key body 22 is removed, the dome sheet recovers its deformation, and the key structure 2 resets under the action of the self-return force of the dome sheet. At the same time, the electrical connection between the dome sheet and the key circuit board 61 is disconnected.

[0083] The limit hook 25 is used to prevent the key structure 2 from slipping off the housing assembly 1a. Exemplarily, a limit portion cooperating with the limit hook 25 may be provided on the outer shell 1 and / or the support member 3. The number of limit hooks 25 can be one or more. Exemplarily, the limit hook 25 can be two, and the two limit hooks 25 are arranged at intervals in the length direction of the pressing structure.

[0084] In some embodiments of the present application, refer to Figure 6, the trigger member 24 can also be formed as part of the limit hook 25. That is, a part of the limit hook 25 is reused as the trigger member 24. In this way, the structure of the button structure 2 can be simplified, and it is beneficial to reduce the size of the mating hole on the housing assembly 1a for accommodating the limit hook 25 and the trigger member 24, which is beneficial to improving the overall structural strength of the housing assembly 1a, and can make the overall structure of the electronic device 100 relatively simple.

[0085] Furthermore, referring to Figure 6 , the button structure 2 further includes a buffer member 23, and the buffer member 23 can be disposed on a side of the trigger member 24 facing away from the button body 22. Exemplarily, the buffer member 23 and the button structure 2 can be fixed by means such as adhesion and snap connection.

[0086] The buffer member 23 can undergo elastic deformation. The buffer member 23 can be a plastic part, a silica gel part, a rubber part, a foam, etc. Exemplarily, the material of the buffer member 23 can be thermoplastic polyurethane (TPU), thermoplastic polyester elastomer (TPEE), etc. Among them, thermoplastic polyurethane and thermoplastic polyester elastomer both have excellent resilience and good wear resistance, which can ensure that the buffer member 23 has good buffering performance.

[0087] In this way, the buffer member 23 can contact the switch member 6, so that the force between the trigger member 24 and the switch member 6 is buffered, which can improve the pressing feel of the button module 20 and can prevent the switch member 6 from being damaged during the pressing process.

[0088] In addition, the electronic device 100 may further include electronic components such as a battery, a camera, an audio module, a speaker, a receiver, a microphone, a headphone jack, a sensor module, and a motor. Among them, the electronic device 100 may have more or fewer components than those described above, may combine two or more components, or may have different component configurations. Each component can be implemented in hardware, software, or a combination of hardware and software including one or more signal processing and / or application specific integrated circuits.

[0089] It should be noted that with the advancement of the thinning of the electronic device 100, the overall thickness of the electronic device 100 becomes thinner and thinner. At the same time, to ensure the feel of the button structure 2, the thickness of the button structure 2 relatively increases, which requires the width of the first through hole 110 on the housing 1 to be relatively increased, resulting in a smaller width of the cross beam on the outer peripheral side of the first through hole 110 on the outer frame 11.

[0090] Among them, the thickness of the button structure 2 refers to the dimension D of the button structure 2 in the thickness direction of the whole machine, that is, the dimension D of the button structure 2 in the Z-axis direction. The relative increase in the thickness of the button structure 2 means that the dimension D of the button structure 2 in the thickness of the whole machine increases. The width of the cross beam refers to the distance L between the inner wall surface of the first through hole 110 and the end surface of the outer frame 11 in the Z-axis direction. The decrease in the width of the cross beam means that the distance L between the inner wall surface of the first through hole 110 and the end surface of the outer frame 11 in the Z-axis direction decreases.

[0091] Continue to refer to Figure 4 , when the support member 3 is connected and fixed to the housing 1, it needs to be connected to the cross beam on the outer peripheral side of the first through hole 110 on the housing 1. However, when both the thickness of the electronic device 100 is reduced and the thickness of the button structure 2 is increased, the width of the cross beam becomes smaller, and the area where the housing 1 and the support member 3 can be connected is smaller, and the connection strength is insufficient. When the electronic device 100 is collided, the housing 1 and the support member 3 are easily separated, and the housing 1 has a high risk of deformation. In particular, the cross beam on the outer peripheral side of the first through hole 110 is easily deformed and bulged, and the button structure 2 is easily stuck, affecting the function of the button structure 2.

[0092] To solve the above technical problems, an embodiment of the present application proposes an electronic device 100. Please refer to Figure 7 and Figure 8 , Figure 7 is a perspective view of the electronic device 100 according to other embodiments of the present application; Figure 8 As shown in Figure 7 , the electronic device 100 includes an outer frame 11, a support member 3, and a button structure 2. The outer frame 11, the button structure 2, and the support member 3 can be designed with reference to the structures of the outer frame 11, the button structure 2, and the support member 3 in any of the above embodiments, and will not be elaborated here.

[0093] Refer to Figure 9 and Figure 10 , and in combination with Figure 8 , Figure 9 As shown in Figure 7 , it is an exploded view of the electronic device 100; Figure 10 is Figure 9 an enlarged view of the circled part at D in; the electronic device 100 further includes a connecting member 4. The connecting member 4 includes a connecting body 41 and an extending portion 42. The connecting body 41 is fixed to the outer frame 11 and is located on the outer peripheral side of the first through hole 110. Specifically, the orthographic projection of the connecting body 41 on the reference plane does not overlap with the orthographic projection of the first through hole 110 on the reference plane. Exemplarily, the connecting body 41 can be located between the outer frame 11 and the inner frame 30.

[0094] In this way, the connecting member 4 can be fixed to the outer frame 11 through the connecting body 41, making the connection between the connecting body 41 and the outer frame 11 convenient, and further making the connection operation between the connecting member 4 and the housing 1 convenient.

[0095] In some embodiments, the connecting body 41 can be in a sheet-like or plate-like shape. In this way, it is beneficial to reduce the superimposed dimensions of the outer frame 11, the inner frame 30, and the connecting body 41 in the second direction (for example, with reference to Figure 10 the X-axis direction in

[0096] The extension portion 42 is fixed to the connecting body 41. Exemplarily, the extension portion 42 and the connecting body 41 can be integrally formed. That is to say, the connecting member 4 can be an integrally formed part. The integrally formed structure can not only ensure the structural and performance stability of the connecting member 4, but also be convenient for molding, simple in manufacturing, and moreover, it eliminates the fittings and connection processes used in the connection of the split structure, and has a high assembly efficiency when assembling the connecting member 4 to the housing.

[0097] The orthographic projection of the extension portion 42 on the reference plane partially overlaps with the orthographic projection of the first through hole 110 on the reference plane, and the reference plane is perpendicular to the axial direction of the first through hole 110. For example, the extension portion 42 protrudes from the inner wall surface of the first through hole 110 in the width direction of the outer frame 11; or, the extension portion 42 can also protrude from the inner wall surface of the first through hole 110 in the length direction of the outer frame 11; or, the extension portion 42 can protrude from the inner wall surface of the first through hole 110 in the width direction of the outer frame 11, and at the same time, the extension portion 42 can also protrude from the inner wall surface of the first through hole 110 in the length direction of the outer frame 11.

[0098] Exemplarily, with reference to Figure 11 , Figure 11 is a schematic diagram of the orthographic projection of the extension portion 42 on the reference plane and the orthographic projection of the first through hole 110 on the reference plane in some embodiments of the present application, Figure 11 the elliptical area in

[0099] is the orthographic projection area of the first through hole 110 on the reference plane, and the shaded area is the overlapping area of the orthographic projection of the connecting member 4 in the reference plane and the orthographic projection of the first through hole 110 on the reference plane.

[0100] In addition, the part of the support member 3 facing the cross beam can be directly connected to the housing 1, or the part of the support member 3 facing the cross beam can also be connected to the housing 1 by means of the connecting member 4; and the part of the support member 3 facing the extension part 42 can be connected to the housing 1 by means of the extension part 42.

[0101] In this way, the connection width between the support member 3 and the housing 1 in the Z-axis direction is increased, thereby increasing the connection area between the support member 3 and the housing 1, and further increasing the connection strength between the support member 3 and the housing 1, so as to enhance the overall stability of the housing 1 and the support member 3. In particular, the connection strength between the area around the first through hole 110 on the outer frame 11 and the connecting member 4 is increased. When the electronic device 100 falls or is impacted, the housing 1 is not easily deformed.

[0102] Therefore, when the overall thickness of the electronic device 100 is made thinner, the thickness of the button structure 2 can be relatively increased. By providing the above-mentioned connecting member 4 on the housing 1 to be connected to the support member 3, while ensuring the connection strength between the housing 1 and the support member 3 and reducing the risk of deformation of the housing 1, the function of the button structure 2 can also be realized, enhancing the user experience.

[0103] In some embodiments of the present application, please refer to Figure 11 and Figure 12 and in combination with Figure 8 Figure 12 FIG. 17 is a schematic structural diagram of the connecting member 4 of the electronic device 100 according to some embodiments of the present application. Figure 12 The area circled by the dashed line in FIG. 17 is the extension part 42. At least a part of the extension part 42 protrudes from the inner wall surface of the first through hole 110 in the width direction of the outer frame 11 (for example, in the Z-axis direction shown in FIG. 17). Figure 8 in FIG. 17.

[0104] The extension part 42 may include a first extension part 421 and a second extension part 422. Exemplarily, the first extension part 421 and the second extension part 422 may be strip-shaped, and the width direction of the first extension part 421 and the second extension part 422 is parallel to the thickness direction of the back cover 12.

[0105] In this way, it is beneficial to increase the connection width between the support member 3 and the outer frame 11 in the width direction of the outer frame 11, thereby being beneficial to increasing the connection area between the support member 3 and the outer frame 11, and further enhancing the reliability of the connection between the support member 3 and the outer frame 11. In particular, the connection strength between the cross beam on the outer frame 11 and the support member 3 is increased, and the support member 3 and the housing 1 are not easily separated. When the electronic device 100 falls or the cross beam is impacted, the cross beam is not easily deformed, and the normal function of the button structure 2 can be ensured.

[0106] ​Moreover, the sum of the dimensions of the cross beam and / or the connection between the main body 41 and the extension 42 in the Z-axis direction is relatively large, increasing the connection width between the support member 3 and the housing 1 in the Z-axis direction. When the connecting member 4 is bonded to the support member 3 through the adhesive layer 5, it is more convenient for dispensing glue, and the dispensing needle does not need to be made too large. It can be understood that the smaller the dispensing needle is made, the higher the cost. Therefore, the extension 42 protrudes from the inner wall surface of the first through hole 110 along the width direction of the outer frame 11, which can also reduce the difficulty of dispensing glue and save costs at the same time.

[0107] In addition, at least a part of the extension 42 protrudes from the inner wall surface of the first through hole 110 along the width direction of the outer frame 11, which is also beneficial to increasing the length of the extension 42, thereby further increasing the connection area between the support member and the housing.

[0108] In some embodiments of the present application, a part of the extension 42 may also protrude from the inner wall surface of the first through hole 110 along the length direction of the outer frame 11 (for example, with reference to Figure 10 the Y-axis direction in

[0109] ). The extension 42 may include a third extension 423 and a fourth extension 424. Exemplarily, the third extension 423 and the fourth extension 424 may be semi-circular.

[0110] In this way, it is beneficial to further increase the connection width between the support member 3 and the outer frame 11 in the width direction of the outer frame 11, thereby further increasing the connection area between the support member 3 and the outer frame 11. At the same time, it is beneficial to increase the connection width between the support member 3 and the outer frame 11 in the length direction of the outer frame 11, thereby increasing the connection area between the support member 3 and the outer frame 11, further enhancing the reliability of the connection between the support member 3 and the outer frame 11. Especially, the connection strength between the area around the first through hole 110 on the outer frame 11 and the support member 3 is increased, and the support member 3 and the housing 1 are not easily separated. When the electronic device 100 drops or the cross beam is collided, the outer frame 11 is not easily deformed, and the normal function of the button structure 2 can be ensured.

[0110] Of course, in other embodiments, the extension 42 may not include one, two, or three of the first extension 421, the second extension 422, the third extension 423, and the fourth extension 424.

[0111] In some embodiments, the connecting member 4 and the support member 3 may be bonded through the adhesive layer 5. Exemplarily, the adhesive layer 5 is conducive to being made of a material with relatively high bonding strength. The adhesive layer 5 has good bonding performance and can realize reliable bonding between the connecting member 4 and the support member 3. At the same time, the adhesive layer 5 has good waterproof and oil-resistant properties. The setting of the adhesive layer 5 can improve the sealing performance between the connecting member 4 and the support member 3, thereby improving the waterproof and oil-proof protection performance of the electronic device 100.

[0112] Exemplarily, the adhesive layer 5 may include at least one of hot melt adhesive and ultraviolet curable adhesive. For example, a liquid curable adhesive may be disposed between the housing 1 and the support member 3 by a dispensing process, and then the curable adhesive is cured to obtain the adhesive layer 5, and the adhesive layer 5 is formed by curing the liquid curable adhesive. In this way, the connection process is simple and easy to operate, and the assembly efficiency can be improved. For example, referring to Figure 14 , Figure 14 FIG. is a schematic structural view of a mating portion between a connection main body and an outer frame according to some embodiments of the present application, Figure 14 The shaded area in is the dispensing area when the connection main body 41 and the support member 3 are connected through the adhesive layer 5.

[0113] In some embodiments of the present application, a glue-blocking protrusion 34 is formed on the end surface of the support member 3 facing the outer frame 11, and the glue-blocking protrusion 34 is located on the side of the extension portion 42 close to the button structure 2. In this way, the glue-blocking protrusion 34 can separate the adhesive layer 5 and the button structure 2, thereby reducing the risk of the glue in the adhesive layer 5 seeping onto the button structure 2 and preventing the button structure 2 from being stuck, which is beneficial to ensuring the function of the button structure 2.

[0114] It should be noted that the above introduction to the connection manner between the connecting member 4 and the support member 3 is only illustrative, and the present application embodiments do not limit the connection manner between the connecting member 4 and the support member 3.

[0115] In some embodiments, please continue to refer to Figure 8 and Figure 12 , the first extension portion 421 and the second extension portion 422 are opposite and spaced apart in the thickness direction of the back cover 12. In this way, it is beneficial to further increase the connection width between the support member 3 and the outer frame 11 in the thickness direction of the back cover 12, thereby further increasing the connection strength between the support member 3 and the outer frame 11, so as to enhance the reliability of the connection between the support member 3 and the housing 1. When the electronic device 100 falls or is impacted, the support member 3 and the housing 1 are not easily separated, and the housing 1 is not easily deformed.

[0116] In order to avoid interference between the extension portion 42 and the button structure 2, in some embodiments, referring to Figure 13 , Figure 13 FIG. is a schematic view of the cooperation between the button structure 2 and the connecting member 4 of the electronic device 100 according to some embodiments of the present application. The button structure 2 is formed with a relief notch 21, and a part of the extension portion 42 may be located in the relief notch 21. Exemplarily, the relief notch 21 is formed on the end surface of the button structure 2 facing the accommodation space 10.

[0117] The clearance notch 21 can avoid the extension portion 42 , and illustratively, the clearance notch 21 can penetrate the end surface of the key structure 2 facing the accommodating space 10 along the Z-axis direction. That is, the extension portion 42 can extend into the clearance notch 21 .

[0118] Combination Figure 6 and Figure 13 The key structure 2 has two trigger members 24 . The clearance gap 21 of some embodiments of the present application can be located between the two trigger members 24 , so that a portion of the connecting member 4 is located in the clearance gap 21 , which helps to prevent the connecting member 4 from hindering the normal movement of the trigger member 24 .

[0119] Alternatively, in other embodiments, in some embodiments of the present application, when at least a portion of the extension portion 42 protrudes from the inner wall surface of the first through hole 110 along the length direction of the outer frame 11, the clearance notch 21 may also penetrate the end surfaces of the key structure 2 at opposite ends in the Y-axis direction along the Y-axis direction. In this way, the clearance notch 21 may be located on the side of the inner wall of the two trigger members 24 facing the first through hole 110.

[0120] Therefore, by forming a clearance notch 21 on the end face of the key structure 2 at one end facing the accommodating space 10, the clearance notch 21 can avoid the extension portion 42, which can not only increase the connection area between the support member 3 and the shell 1 and enhance the connection strength between the shell 1 and the support member 3, but also help to avoid the connecting member 4 hindering the normal movement of the key structure 2, thereby ensuring the function of the key structure 2.

[0121] In some embodiments of the present application, reference Figure 8 The connecting body 41 is fixed to at least one of the first beam 111 and the second beam 112. For example, the connecting body 41 can be fixed to the first beam 111; or, the connecting body 41 can also be fixed to the second beam 112; or, the connecting body 41 can be fixed to both the first beam 111 and the second beam 112.

[0122] By fixing the connecting body 41 on at least one of the first beam 111 and the second beam 112, the overall structural strength of the connecting body 41, the first beam 111 and the second beam 112 is relatively large and has high stability. When the electronic device 100 falls or is collided, the risk of deformation of the first beam 111 and the second beam 112 can be further reduced, and the function of the key structure 2 can be better guaranteed.

[0123] Moreover, the sum of the dimensions of the connecting body 41 and the extension part 42 in the Z-axis direction is further increased, and the connection width between the support member 3 and the housing 1 in the Z-axis direction is also further increased. When the connecting member 4 and the support member 3 are bonded through the adhesive layer 5, it is more convenient for dispensing glue, the difficulty of dispensing glue can be further reduced, and the cost can be saved.

[0124] In some embodiments of the present application, refer to Figure 14 , Figure 14 which is a schematic structural view of the mating part between the connecting body 41 and the outer frame 11 in some embodiments of the present application. The connecting body 41 has an avoidance hole 410, the avoidance hole 410 is opposite to and communicated with the first through hole 110, and the key structure 2 is inserted through the avoidance hole 410. In this case, the connecting body 41 can be formed in a ring shape, and the extension part 42 can protrude from the hole wall surface of the avoidance hole 410. Exemplarily, the connecting body 41 includes a first connecting arm 411 and a second connecting arm 412 that are opposite and spaced apart in the thickness direction of the back cover 12, and a third connecting arm 413 and a fourth connecting arm 414 that are opposite and spaced apart in the third direction. Both the third connecting arm 413 and the fourth connecting arm 414 are connected between the first connecting arm 411 and the second connecting arm 412.

[0125] Through the setting of the avoidance hole 410, it is possible to prevent the connecting member 4 from hindering the movement of the key and ensure the key function. And the connecting body 41 can be formed in a ring shape, which can further increase the connection area between the connecting member 4 and the housing 1, and can also increase the connection area between the connecting member 4 and the support member 3, further increasing the connection strength of the overall structure of the housing 1, the connecting member 4 and the support member 3, and better ensuring the stability of the overall structure of the housing 1, the connecting member 4 and the support member 3.

[0126] It can be understood that in other embodiments, the connecting body 41 may not include at least one of the third connecting arm 413 and the fourth connecting arm 414. Or, the connecting body 41 may not include one of the first connecting arm 411 and the second connecting arm 412.

[0127] In some embodiments of the present application, refer to Figure 8 and Figure 10 , a first groove 32 is formed on the end face of the support member 3 facing the outer frame 11, and both the connecting body 41 and the extension part 42 are fixed within the groove wall surface of the first groove 32. The first groove 32 may be formed by the partial end face of the inner frame 30 facing the outer frame 11 being recessed in a direction away from the outer frame 11. That is, the first groove 32 penetrates the end face of the inner frame 30 facing the outer frame 11.

[0128] Exemplarily, an adhesive layer 5 is provided in the first groove 32. The connection main body 41 and the extension part 42 can be connected to the support member 3 through the adhesive layer 5. In this way, at least part of the connection main body 41 and the extension part 42 can be received in the first groove 32; alternatively, the connection main body 41 and the extension part 42 are not received in the first groove 32.

[0129] By fixing both the connection main body 41 and the extension part 42 within the groove wall surface of the first groove 32, the stacked dimensions of the support member 3, the connection member 4, and the adhesive layer 5 can be reduced, making the overall structure of the connection member 4 and the support member 3 more compact, which helps with the thin and light design of the electronic device 100. Fixing the connection main body 41 and the extension part 42 within the groove wall surface of the first groove 32 also makes the connection between the connection member 4 and the support member 3 tighter, which helps to enhance the connection strength between the connection member 4 and the support member 3.

[0130] In some embodiments of the present application, please refer to Figure 8 and Figure 12 , the connection member 4 further includes a connection flange 43. The connection flange 43 is fixed to the connection main body 41, and the connection flange 43 is bent away from the outer frame 11 relative to the connection main body 41. In this way, the connection flange 43 is located on the side of the connection main body 41 facing away from the housing 1, facilitating the connection between the connection flange 43 and the support member 3.

[0131] And it can further increase the connection area between the connection member 4 and the support member 3, thereby increasing the connection area between the housing 1, the connection member 4 as a whole and the support member 3, and further enhancing the connection strength between the housing 1 and the support member 3 to increase the stability of the overall connection between the housing 1 and the support member 3. When the electronic device 100 drops or is impacted, it is not easy for the housing 1 and the support member 3 to separate, further reducing the risk of deformation of the housing 1.

[0132] It should be noted that the connection flange 43 can be fixed to the connection main body 41 by means of welding, bonding, or fastener connection. Alternatively, the connection flange 43 can also be integrally formed with the connection main body 41.

[0133] In some embodiments, the connection flange 43 can be in the shape of a sheet or a plate. For example, the connection flange and the connection main body can be in an L shape as a whole. This is beneficial for reducing the stacked dimensions of the outer frame 11, the inner frame 30, and the connection flange 43 in the Z-axis direction, thereby facilitating the reduction of the size of the electronic device 100 in the first direction and realizing the miniaturization design of the electronic device 100.

[0134] In some other embodiments of the present application, the connecting flange 43 can also be fixed to the extension portion 42, and the connecting flange 43 is bent in a direction away from the outer frame 11 relative to the connecting body 41. The connecting flange 43 is located on the side of the extension portion 42 facing away from the housing 1, which also facilitates the connection between the connecting flange 43 and the support member 3. Moreover, the connection area between the connecting member 4 and the support member 3 can be further increased to enhance the connection strength between the connecting member 4 and the support member 3, thereby increasing the overall connection stability between the housing 1 and the support member 3.

[0135] Please refer to Figure 8 and Figure 12 , the connecting flange 43 includes a first connecting surface 430, the support member 3 includes a second connecting surface 310, the first connecting surface 430 is connected to the second connecting surface 310 and the first connecting surface 430 and the second connecting surface 310 are opposite to each other in a first direction, and the first direction is perpendicular to the axial direction of the first through hole 110. For example, the first direction can be the Z-axis direction, and the first direction can also be the Y-axis direction.

[0136] By making the first connecting surface 430 of the connecting flange 43 and the second connecting surface 310 of the support member 3 opposite to each other in the first direction, it is more convenient to connect the connecting flange 43 and the support member 3, and further makes the connection operation between the connecting member 4 and the support member 3 convenient. The support member 3 can be connected to the housing 1 by means of the connecting flange 43, further increasing the connection area between the support member 3 and the housing 1 and increasing the connection strength between the support member 3 and the housing 1. In this way, when the electronic device 100 drops or is impacted, the housing 1 is not easily deformed.

[0137] In some embodiments of the present application, please refer to Figure 8 , the support member 3 includes a first end face 3a and a second end face 3b that are opposite to each other in the first direction, and at least one of the first end face 3a and the second end face 3b includes the second connecting surface 310. For example, one of the first end face 3a and the second end face 3b includes the second connecting surface 310; or, both the first end face 3a and the second end face 3b include the second connecting surface 310.

[0138] By having at least one of the first end face 3a and the second end face 3b include the second connecting surface 310, the connecting flange 43 can be connected to at least one of the first end face 3a and the second end face 3b, and the area of the end face of the support member 3 in the first direction is relatively large. In this way, when the support member 3 is connected to the housing 1 by means of the connecting flange 43, the connection area between the support member 3 and the housing 1 can be further increased, the connection strength between the support member 3 and the housing 1 can be increased, and the reliability of the connection between the support member 3 and the housing 1 can be further enhanced.

[0139] In some embodiments of the present application, please refer to Figure 15 , Figure 15Partial cross-sectional structure schematic of the electronic device 100 according to some embodiments of the present application Figure One The inner wall surface of the second through hole 31 includes a second connection surface 310. In this way, at least a part of the connecting flange 43 extends into the second through hole 31. The connecting flange 43 and the inner wall of the second through hole 31 are opposite in the first direction, and the connecting flange 43 is connected to the inner wall of the second through hole 31.

[0140] It should be noted that there is a certain distance between the connecting flange 43 extending into the second through hole 31 and the key structure 2 to ensure that the connecting flange 43 does not affect the movement of the key structure 2. For example, the shape of the orthographic projection of the avoidance hole 410 on the reference plane can be the same as the shape of the orthographic projection of the second through hole 31 on the reference plane, and the size of the orthographic projection of the avoidance hole 410 on the reference plane can be the same as the size of the orthographic projection of the opening of the second through hole 31 on the reference plane, which is convenient for the movement of the key structure 2.

[0141] By connecting the connecting flange 43 of the connecting member 4 to the inner wall of the second through hole 31, the connecting member 4 can be connected to the support member 3, enhancing the connection strength between the connecting member 4 and the support member 3, and thus enhancing the connection strength between the housing 1 and the support member 3. And it can be understood that the connecting flange 43 is located on the outer peripheral side of the key structure 2, then the connecting flange 43 is adjacent to the cross beam on the outer peripheral side of the first through hole 110. In this way, the connection strength between the cross beam around the first through hole 110 on the housing 1 and the connecting member 4 can be better enhanced. When the electronic device 100 drops or is collided, the risk of deformation of the housing 1 when the electronic device 100 drops or is collided is further reduced. The cross beam around the first through hole 110 is not easily deformed, and the function of the key structure 2 can be ensured.

[0142] It can be understood that when the inner wall surface of the second through hole 31 includes the second connection surface 310, at least one of the first end surface 3a and the second end surface 3b of the support member 3 can include the second connection surface 310, or can not include the second connection surface 310.

[0143] In some embodiments of the present application, referring to Figure 8 and Figure 10 , a second groove 33 is provided on the second connection surface 310, and the connecting flange 43 is fixed to the groove wall surface of the second groove 33.

[0144] When the second connection surface 310 is on the end surface of the support member 3 in the first direction, the second groove 33 can be formed by the partial end surface of the inner frame 30 in the first direction being recessed away from the outer frame 11, that is, the second groove 33 penetrates the end surface of the inner frame 30 in the first direction facing the outer frame 11. When the second connection surface 310 is located on the inner wall of the second through hole 31, the second groove 33 can be formed by the partial inner wall of the second through hole 31 being recessed in the direction of the end surface of the support member 3 in the first direction.

[0145] Exemplarily, an adhesive layer 5 is provided in the second groove 33, and the connecting flange 43 can be connected to the support member 3 through the adhesive layer 5. In this way, at least part of the connecting flange 43 can be received in the second groove 33; or, the connecting flange 43 is not received in the second groove 33. In this way, the superimposed dimensions of the support member 3, the connecting flange 43, and the adhesive layer 5 can be reduced, making the overall structure of the connecting member 4 and the support member 3 more compact, which helps the thin and light design of the electronic device 100. Fixing the connecting flange 43 in the second groove 33 also makes the connection between the connecting flange 43 and the support member 3 tighter, which helps to enhance the connection strength between the connecting member 4 and the support member 3.

[0146] In this way, at least part of the connecting flange 43 can be received in the second groove 33; or, the connecting flange 43 is not received in the second groove 33, and at least part of the connection structure (such as the adhesive layer 5) between the connecting body 41 and the support member 3 can be received in the second groove 33. In this way, the overall structure of the connecting member 4 and the support member 3 is made more compact, which helps the thin and light design of the electronic device 100.

[0147] It should be noted that when the second connection surface 310 is located on the end surface of the support member 3 in the first direction, the second groove 33 is opened on the end surface of the support member 3 in the first direction, which facilitates the connection operation between the connecting flange 43 and the support member 3; when the second connection surface 310 is located on the inner wall of the second through hole 31 of the support member 3, the second groove 33 is opened on the inner wall of the second through hole 31, and at least part of the connecting flange 43 and the adhesive layer 5 are received in the second through hole 31, making the overall structure of the connecting member 4 and the support member 3 more compact.

[0148] Among them, the connecting flange 43 can be one or more, and "more than one" means two or more.

[0149] When the connecting flange 43 is one, referring to Figure 8 , the connecting flange 43 can be located at one end of the connecting body 41 in the first direction (that is, the thickness direction of the back cover 12), and the second groove 33 can be opened on the end surface of the support member 3 in the first direction. Or, referring to Figure 15, the connecting flange 43 can also be located at other positions of the connecting body 41 except for the two ends in the first direction, such as the outer peripheral side of the avoidance hole 410. At least a part of the connecting flange 43 is located in the second through hole 31. The second groove 33 can be formed on the inner wall of the second through hole 31, and the connecting flange 43 is connected to the inner wall of the second through hole 31. The surfaces of the connecting flange 43 facing the support 3 can all serve as the first connecting surface 430. The inner wall of the second groove 33 has a second connecting surface 310, and the first connecting surface 430 and the second connecting surface 310 face each other in the first direction. When the connecting member 4 and the support 3 are bonded through the adhesive layer 5, the first connecting surface 430 and the second connecting surface 310 are bonded through the adhesive layer 5.

[0150] When there are two connecting flanges 43, there can also be two second grooves 33. Refer to Figure 16 , Figure 16 is a schematic cross-sectional structure of a part of the electronic device 100 according to some embodiments of the present application Figure Two ; the connecting flange 43 can be located at opposite ends of the connecting body 41 in the first direction. One of the second grooves 33 can be formed on the end face of the support 3 in the first direction, and the other second groove 33 can also be formed between the end face of the support 3 in the first direction and the inner wall of the second through hole 31. The two connecting flanges 43 are respectively received in their corresponding second grooves 33.

[0151] Refer to Figure 17 and Figure 18 , Figure 17 is a schematic cross-sectional structure of a part of the electronic device 100 according to some embodiments of the present application Figure Three ; Figure 18 is a schematic cross-sectional structure of a part of the electronic device 100 according to some embodiments of the present application Figure Four . It can also be that one of the connecting flanges 43 is located at one end of the connecting body 41 in the first direction, and the other connecting flange 43 is located at other positions of the connecting body 41 except for the two ends in the first direction (such as the outer peripheral side of the avoidance hole 410). One of the second grooves 33 can be formed on the end face of the support 3 in the first direction, and the other second groove 33 can also be formed on the inner wall of the second through hole 31. The two connecting flanges 43 are respectively received in their corresponding second grooves 33.

[0152] Refer to Figure 19 , Figure 19 is a schematic cross-sectional structure of a part of the electronic device according to some embodiments of the present application Figure Five , or it can be that both of the connecting flanges 43 are located at other positions of the connecting body 41 except for the two ends in the first direction. The two second grooves 33 can both be formed on the inner wall of the second through hole 31 and face each other in the first direction. Both of the connecting flanges 43 are received in the second grooves 33.

[0153] When there are two or more connecting flanges 43, refer to Figure 20 , Figure 20 which is a schematic cross-sectional structure of a part of the electronic device 100 according to some embodiments of the present application Figure Six . The multiple connecting flanges 43 can be arranged at intervals along the first direction on the side of the connecting body 41 facing away from the housing 1. Figure 20 As shown in, there are three connecting flanges 43. The three corresponding second grooves 33 are also arranged at intervals along the first direction. Two of the second grooves 33 are opened on the inner wall of the second through hole 31 and are opposite to each other in the first direction, and the other second groove 33 is opened on the end face of the support member 3 in the first direction.

[0154] In the above embodiments, the surfaces of the connecting flanges 43 facing the support member 3 can all be used as the first connecting surfaces 430. The first connecting surfaces 430 and the second connecting surfaces 310 are opposite to each other in the first direction. For example, when the connecting member 4 and the support member 3 are bonded through the adhesive layer 5, the first connecting surface 430 and the second connecting surface 310 are bonded through the adhesive layer 5 to realize the connection between the connecting member 4 and the support member 3.

[0155] According to some other embodiments of the present application, refer to Figure 21 , Figure 21 which is a schematic cross-sectional structure of a part of the electronic device 100 according to some embodiments of the present application Figure Seven . The connecting member 4 may not include the connecting flange 43. The connecting body 41 and the extension portion 42 of the connecting member 4 are both connected to the support member 3, which has achieved the effect of increasing the connection area between the connecting member 4 and the support member 3, and can ensure the connection stability between the housing 1, the connecting member 4, and the support member 3. Adding the connecting flange 43 on the connecting member 4 can further enhance the connection strength between the housing 1, the connecting member 4, and the support member 3.

[0156] The number and setting positions of the above connecting flanges 43 and the number and setting positions of the second grooves 33 are only exemplary, and the embodiments of the present application do not limit this.

[0157] According to some embodiments of the present application, the housing 1 can be a metal part, and the connecting member 4 is welded to the housing 1. Such a connection method makes the connection between the housing 1 and the connecting member 4 highly reliable, can enhance the stability of the overall structure of the housing 1 and the connecting member 4, is relatively convenient to connect, and can connect structures of different materials and different sizes according to needs, and can meet different requirements.

[0158] The connecting body 41 and the outer frame 11 can also be fixed by means of bonding, fastener connection, etc. Among them, the fasteners can include at least one of screws, bolts or rivets.

[0159] For example, the connecting member 4 and the housing 1 can be connected by double-row overlapping welding. The positions of the double-row overlapping welding points between the connecting member 4 and the housing 1 can be referred to Figure 22 , Figure 22 which is a partial schematic view of the positions of the welding points between the connecting member 4 and the housing 1 in some embodiments of the present application; Figure 22 The positions of the circles in

[0160] can be regarded as the positions of the welding points where the connecting member 4 is welded to the housing 1. It should be noted that the above introduction to the connection method between the connecting member 4 and the housing 1 is only illustrative, and the embodiments of the present application do not limit the connection method between the connecting member 4 and the housing 1.

[0161] Taking the housing 1 as a metal part, the connecting member 4 as a metal part, and the support member 3 as a plastic part as an example, when assembling the housing 1, the connecting member 4, and the support member 3, the connecting member 4 can be first welded to the housing 1 to improve the overall connection strength between the housing 1 and the connecting member 4, and then the surface of the side of the connecting member 4 facing the support member 3 is bonded to the support member 3 through the adhesive layer 5. The viscosity of the glue is good, making the connection reliability between the connecting member 4 and the support member 3 higher. Since the orthographic projection of the extension part 42 on the reference plane overlaps with the orthographic projection of the first through hole 110 on the reference plane, this is equivalent to increasing the area of the surface of the side of the connecting member 4 facing the support member 3, thereby increasing the connection area between the connecting member 4 and the support member 3, and further increasing the connection area between the housing 1, the connecting member 4 as a whole and the support member 3, so as to increase the connection strength between the housing 1 and the support member 3, realize a highly stable integrated structure between the housing 1 and the support member 3, and reduce the risk of deformation of the housing 1 when encountering collisions.

[0162] Of course, the above introduction to the assembly process of the housing 1, the connecting member 4, and the support member 3 is also illustrative, and the embodiments of the present application do not limit the assembly process of the housing 1, the connecting member 4, and the support member 3. For example, the housing 1 and the connecting member 4 can also be connected through the adhesive layer 5, and the support member 3 and the connecting member 4 can be connected by welding; or, the housing 1 and the connecting member 4, the connecting member 4 and the support member 3 can also be connected by snap connection.

[0163] In some other embodiments of the present application, referring to Figure 23 , Figure 23 which is a partial cross-sectional structure schematic view of the electronic device 100 in some other embodiments of the present application, the connecting member 4 may not include the extension part 42.

[0164] For example, referring to Figure 24 , Figure 24 which is a structural schematic view of the connecting member 4 in some other embodiments of the present application, the connecting member 4 includes a connecting body 41 and a connecting flange 43. Referring to Figure 25 , Figure 25Schematic diagram of the cooperation between the connection body 41 and the outer frame 11 in some other embodiments of the present application, where Figure 25 The shaded area in

[0165] is the dispensing area when the connection body 41 is connected to the support member 3 through the adhesive layer 5. By connecting through the connecting flange 43 to the support member 3, on the one hand, the connection area between the connecting member 4 and the support member 3 can be increased, and the connection strength between the connecting member 4 and the support member 3 can be increased. The connection area between the overall structural member formed by the connecting member 4 and the outer shell 1 and the support member 3 is increased, thereby increasing the connection strength between the outer shell 1 and the support member 3, and further enhancing the overall stability of the outer shell 1 and the support member 3. When the electronic device 100 falls or is impacted, the outer shell 1 is not easily deformed. On the other hand, the pressing stroke of the button structure 2 can be unrestricted by the wall thickness of the outer shell 1. Whether the wall thickness of the outer shell 1 meets or does not meet the pressing stroke of the button structure 2, the button structure 2 is not easily blocked by the connecting member 4, which can ensure the function of the button structure 2.

[0166] In some embodiments, when the wall thickness of the outer shell 1 is small and less than the sum of the effective overlap amount between the button structure 2 and the outer shell 1 and the pressing stroke of the button structure 2, the wall thickness of the outer shell 1 cannot meet the stroke of the button structure 2, and a part of the structure of the button structure 2 will enter the accommodation space 10 of the outer shell 1 along the pressing direction. The wall thickness of the outer shell 1 can be considered as the axial length of the first through hole 110. That the wall thickness of the outer shell 1 can meet the stroke of the button structure 2 can be considered that the axial length of the first through hole 110 can meet the effective overlap width between the button structure 2 and the outer shell 1, and at the same time, the axial length of the first through hole 110 also needs to meet the pressing stroke of the button structure 2.

[0167] In this way, if the orthographic projection of the extension part 42 on the reference plane overlaps with the orthographic projection of the first through hole 110 on the reference plane, the button structure 2 is easily blocked by the extension part 42, affecting the function of the button structure 2. In this case, the connecting member 4 may not be provided with the extension part 42, so as to avoid the extension part 42 interfering with the normal movement of the button structure 2.

[0168] Here is an example. The effective overlap amount between the button structure 2 and the outer shell 1 is 0.45 mm, the pressing stroke of the button structure 2 is 0.5 mm, and the sum of the effective overlap amount between the button structure 2 and the outer shell 1 and the pressing stroke of the button structure 2 is 0.95 mm. This requires that the wall thickness of the outer shell 1 is not less than 0.95 mm. When the wall thickness of the outer shell 1 is less than 0.95 mm, for example, the wall thickness of the outer shell 1 is 0.8 mm, and the sum of the effective overlap amount between the button structure 2 and the outer shell 1 and the pressing stroke of the button structure 2 is 0.95 mm, the outer shell 1 does not meet the stroke requirement of the button structure 2. In this way, the connecting member 4 may not be provided with the extension part 42 to avoid the extension part 42 interfering with the normal movement of the button structure 2.

[0169] The connecting member 4 of the above embodiment is applicable to the case where the wall thickness of the housing 1 is relatively thick, that is, the wall thickness of the housing 1 can meet the stroke of the button structure 2.

[0170] The structure and the setting position of the connecting flange 43 can be designed with reference to the connecting flange 43 in any of the above embodiments, and will not be elaborated here.

[0171] In some other embodiments of the present application, a button structure 2 is further provided. Figure 26 FIG. is a perspective view of the button structure 2 of the electronic device 100 in some other embodiments of the present application. The difference between the button structure 2 and the button structure 2 of the above embodiment is that the trigger member 24 and the limit hook 25 are independent of each other, and the trigger member 24 can be located between the two limit hooks 25. The two trigger members 24 are connected by a reinforcing block 26, so that the structures of the two trigger members 24 are relatively stable, and the entire button structure 2 has higher structural strength.
