Description

Technical Field

[0001] This application belongs to the field of electronic device technology, specifically relating to a button structure and an electronic device. Background Technology

[0002] In related technologies, TPU is used to fabricate the mounting feet for side buttons. However, due to space limitations, the interference width between the TPU mounting feet and the mid-frame is small, posing a risk of the side button falling off when it shakes. Furthermore, the TPU mounting feet are weak; when a user presses one end of the side button, the other end may warp and flip outwards, making the TPU mounting feet prone to deformation and causing the side button to detach. Summary of the Invention

[0003] This application aims to provide a button structure and electronic device that solves the problem of existing side buttons easily falling off.

[0004] To solve the above-mentioned technical problems, this application is implemented as follows:

[0005] In a first aspect, embodiments of this application propose a button structure, including:

[0006] The button body has a pressing side and an assembly side opposite to each other along its thickness direction, and a first end and a second end that are set opposite to each other along its length direction;

[0007] A metal hook is provided on the assembly side. The metal hook includes a connecting part and a limiting part. The connecting part is connected to the assembly side. One end of the limiting part is connected to the connecting part. The other end of the limiting part is inclined toward the first end of the button body.

[0008] When the button structure is in the installed state, one end of the limiting part that is away from the connecting part protrudes from the end face of the first end of the button body in the length direction of the button body.

[0009] Secondly, embodiments of this application provide an electronic device, including:

[0010] The button structure described above is assembled in the electronic device in the aforementioned installation state.

[0011] In the embodiments of this application, when the button structure is in the installed state, the end of the limiting part away from the connecting part protrudes from the end face of the first end of the button body in the length direction of the button body, so that the part of the limiting part protruding from the button body can be locked with the frame of the electronic device, realizing the assembly between the button structure and the frame of the electronic device. Since the metal hanging foot has high structural strength, the limiting part can be locked with the frame more firmly and is not easy to shake, thereby greatly reducing the risk of the button structure falling off.

[0028] The following is combined with Figure 1 - Figure 8 This application describes a button structure 10 and an electronic device according to embodiments thereof.

[0029] Specifically, the button structure 10 can be applied in electronic devices to realize the control functions of the electronic devices. For example, the button structure 10 can be used to turn the electronic device on, off, or restart it; or, the button structure 10 can be used to adjust the volume of the electronic device; or, the button structure 10 can be used to quickly return to the main page of the electronic device, etc.

[0030] Furthermore, the electronic device may include a frame 20, on which a button slot 21 may be provided. The button structure 10 is installed in the button slot 21, which facilitates the installation of the button structure 10 onto the frame 20 and also facilitates the operation of the button structure 10. For example, the button slot 21 may be provided on the side or front of the frame 20 to install the button structure 10 on the side or front of the frame 20, etc. This embodiment does not specifically limit this. This embodiment takes the installation of the button structure 10 on one side of the frame 20 as an example, that is, when the button structure 10 is a side button, as an example. Other situations can be set with reference to this.

[0031] like Figure 1 As shown, the button structure 10 includes: a button body 11 having a pressing side 112 and an mounting side 111 opposite to each other along its thickness direction, and a first end 113 and a second end 114 disposed opposite to each other along its length direction; a metal hanger 121 disposed on the mounting side 111, the metal hanger 121 including a connecting part 1211 and a limiting part 1212, the connecting part 1211 being connected to the mounting side 111, one end of the limiting part 1212 being connected to the connecting part 1211, and the other end of the limiting part 1212 being inclined toward the first end 113 of the button body 11; when the button structure 10 is in the installed state, the end of the limiting part 1212 opposite to the connecting part 1211 protrudes from the end face of the first end 113 of the button body 11 along the length direction of the button body 11.

[0032] In the embodiments of this application, when the button structure 10 is in the installed state, the end of the limiting part 1212 away from the connecting part 1211 protrudes from the end face of the first end 113 of the button body 11 in the length direction of the button body 11, so that the part of the limiting part 1212 protruding from the button body 11 can be locked and engaged with the frame 20 of the electronic device, realizing the assembly between the button structure 10 and the frame 20 of the electronic device. Since the metal hanging foot 121 has high structural strength, the limiting part 1212 can be locked and engaged with the frame 20 more firmly and is not easy to shake, thereby greatly reducing the risk of the button structure 10 falling off.

[0033] In this embodiment, the button body 11 is the main structure of the button structure 10 and is used to arrange the mounting component 12. The button body 11 has a pressing side 112 and an assembly side 111 along its thickness direction. The assembly side 111 can be inserted into the button slot 21 on the frame 20. The user can operate the button structure 10 by pressing the pressing side 112 of the button body 11.

[0034] Combination Figure 1 and Figure 2 As shown, direction S1 is the thickness direction of button body 11, and direction S2 is the length direction of button body 11.

[0035] Specifically, the metal hanging feet 121 are disposed on the assembly side 111 and can be used for installation and mating with the frame 20. Furthermore, the number of metal hanging feet 121 can be one, two, or three, etc., and this embodiment does not specifically limit this.

[0036] Specifically, the metal hook 121 can be made of metal material, giving it high structural strength. The metal material can be aluminum or aluminum alloy, etc. The button body 11 can be made of at least one of metal, plastic, or silicone; this embodiment does not specifically limit the material. Taking the button body 11 and the metal hook 121 as examples where both are metal, aluminum alloy material can be prepared, and the button structure 10 can be fabricated using computer numerical control (CNC) machining.

[0037] Specifically, this application utilizes the structural strength of the metal hanger 121 to achieve good assembly between the button structure 10 and the frame 20. It has fewer structural parts, lower manufacturing cost, smaller space occupation, higher reliability, and lower cost.

[0038] Specifically, the metal hanging foot 121 includes a connecting part 1211 and a limiting part 1212. The connecting part 1211 is connected to the mounting side 111. One end of the limiting part 1212 is connected to the connecting part 1211. The other end of the limiting part 1212 can be tilted toward the first end 113 near the button body 11. The connecting part 1211 can support the limiting part 1212.

[0039] Specifically, one end of the limiting part 1212 can be used as a fixed end and connected to the connecting part 1211, while the other end of the limiting part 1212 can be used as a movable end. The movable end can change position when subjected to pressure, so that the connection between the limiting part 1212 and the connecting part 1211 can be bent and deformed.

[0040] Specifically, when the button structure 10 is in the installation state, the movable end of the limiting part 1212 can protrude from the end face of the first end 113 along the length direction of the button body 11, so that the movable end of the limiting part 1212 can be engaged with the frame 20, thereby installing the button structure 10 into the frame 20 of the electronic device. Since the metal hanging foot 121 has strong structural strength, the connection between the limiting part 1212 and the frame 20 is relatively reliable.

[0041] Optionally, when the button structure 10 is not installed, one end of the limiting part 1212 that is away from the connecting part 1211 is recessed in the length direction of the button body 11 to the end face of the first end 113 of the button body 11, which can reduce the risk of interference from the limiting part 1212 during the process of inserting the button body 11 into the button slot 21.

[0042] Furthermore, by applying an external force to the limiting part 1212 along the thickness direction of the button body 11, the button structure 10 can be switched from an uninstalled state to an installed state, making the installation of the button structure 10 more convenient.

[0043] Specifically, the limiting part 1212 is recessed into the button body 11, which means that the limiting part 1212 retracts into the interior of the button body 11 and is located inside the circumferential boundary of the button body 11, without reaching or exceeding the boundary. That is, the projection of the limiting part 1212 along the thickness direction of the button body 11 falls within the projection of the button body 11 along its thickness direction.

[0044] Specifically, protrusion is the opposite of inward retraction. At least a portion of the limiting portion 1212 protrudes from the button body 11, indicating that at least a portion of the limiting portion 1212 protrudes and extends outward beyond the circumferential boundary of the button body 11. That is, the projection of at least a portion of the limiting portion 1212 along the thickness direction of the button body 11 does not overlap with the projection of the button body 11 along its thickness direction.

[0045] Furthermore, in order to ensure that the limiting part 1212 deforms to the specified size protruding from the button body 11 during the assembly process of the button structure 10 and to ensure the feel of the button structure 10, a metal stop 122 can be provided on the assembly side 111 of the button body 11. Moreover, the metal stop 122 is made of metal material, has strong structural strength, is not easily deformed, and can better support and limit the limiting part 1212.

[0046] Specifically, the metal stop 122 can be disposed between the first end 113 and the connecting part 1211 along the length direction of the button body 11; when the button structure 10 is in the installed state, the limiting part 1212 abuts against the metal stop 122.

[0047] In this embodiment, the metal stop 122 is made of metal material, which has strong structural strength and is not easily deformed. It can better support and limit the limiting part 1212, thereby ensuring the straightness of the limiting part 1212 and preventing the straightness of the limiting part 1212 from changing during the process of being subjected to external force, thus improving the reliability of the locking and engagement between the limiting part 1212 and the frame 20.

[0048] Specifically, the limiting part 1212 may include a first form and a second form. In the first form, the button structure 10 is in a non-installed state, and in the second form, the button structure 10 is in an installed state.

[0049] Optionally, when the button structure 10 is not installed, the limiting part 1212 can be separated from the metal stop 122 and spaced apart, so that one end of the limiting part 1212 away from the connecting part 1211 is far away from the metal stop 122. This makes it easier to make one end of the limiting part 1212 away from the connecting part 1211 recessed in the length direction of the button body 11 at the end face of the first end 113 of the button body 11. In this way, the risk of interference from the limiting part 1212 can be reduced during the process of inserting the button body 11 into the button slot 21.

[0050] Specifically, when the button structure 10 is not installed, the limiting part 1212 can be separated from the metal stop 122 and spaced apart, and the included angle between the limiting part 1212 and the mounting side 111 is an acute angle; when the button structure 10 is installed, the limiting part 1212 abuts against the metal stop 122, so that the limiting part 1212 is parallel to the mounting side 111.

[0051] Specifically, during the process of inserting the button structure 10 into the button slot 21, the limiting part 1212 first enters the button slot 21. As it enters the button slot 21 along with the button body 11, the limiting part 1212 abuts against the bottom of the button slot 21 and is then compressed and deformed. This allows the button body 11 to apply external force to the limiting part 1212 along its thickness direction until the limiting part 1212 abuts against the metal stop 122. At this point, the button structure 10 switches from the non-installed state to the installed state, and the limiting part 1212 switches to the installed state. In the second configuration, at least a portion of the limiting part 1212 protrudes from the button body 11 along its length, facilitating a snap-fit ​​engagement between the protruding portion of the limiting part 1212 and the frame 20. Due to the high structural strength of the limiting part 1212, even with a small engagement size, the snap-fit ​​between the limiting part 1212 and the frame 20 still ensures a secure connection between the button structure 10 and the frame 20, reducing the risk of the button structure 10 wobbling and thus the risk of it falling. Furthermore, the limiting part 1212 and the frame 20 have sufficient engaging force, allowing the metal hook 121 to provide good structural support when the button structure 10 is pressed, reducing tactile discomfort and minimizing the risk of the limiting part 1212 deforming and causing the button body 11 to warp and flip outwards, further reducing the risk of the button structure 10 falling.

[0052] Specifically, the process of inserting the button structure 10 into the button slot 21 includes: as follows Figure 3 As shown, align the mounting side 111 of the button body 11 with the opening of the button slot 21, then insert the metal hanger 121 into the button slot 21, and apply a pushing force F1 to the pressing side 112 of the button body 11. The initial insertion state is as follows. Figure 4 and Figure 5 As shown, at this time, the movable end of the limiting part 1212 abuts against the bottom of the key slot 21, and its movement is restricted by the resistance of the frame 20. Under the continuous action of the thrust F1, the connection between the limiting part 1212 and the connecting part 1211 bends under the action of the bending moment, causing the movable end of the limiting part 1212 to move until the limiting part 1212 abuts against the metal stop 122. The part of the limiting part 1212 that protrudes from the key body 11 in the length direction of the key body 11 is engaged with the frame 20. The key body 11 no longer displaces under the action of the thrust F1, reaching the final state, as shown. Figure 6 and Figure 7 As shown.

[0053] Optionally, in order to ensure the straightness of the limiting part 1212 and to prevent the straightness of the limiting part 1212 from changing during the process of being subjected to external force, the connection between the limiting part 1212 and the connecting part 1211 can be designed to be more easily bent and deformed. In this way, when subjected to external force, the connection between the limiting part 1212 and the connecting part 1211 will be bent, making it easier for the limiting part 1212 to switch from the first form to the second form.

[0054] Optionally, in order to make the connection between the limiting part 1212 and the connecting part 1211 easier to bend and deform, the structural strength of the connection between the limiting part 1212 and the connecting part 1211 can be reduced. According to the stress analysis results, the cross-sectional area of ​​the connection between the limiting part 1212 and the connecting part 1211 can be reduced so that the cross-sectional area of ​​the connection between the limiting part 1212 and the connecting part 1211 is smaller than the cross-sectional area of ​​the limiting part 1212. Alternatively, a slot can be provided at the connection between the limiting part 1212 and the connecting part 1211 to increase the slot design, so that the connection between the limiting part 1212 and the connecting part 1211 has a groove.

[0055] Optionally, when the button structure 10 is in the installed state, the distance between one end of the limiting part 1212 away from the connecting part 1211 and the mounting side 111 in the thickness direction of the button body 11 is a; when the button structure 10 is in the uninstalled state, the distance between one end of the limiting part 1212 away from the connecting part 1211 and the mounting side 111 in the thickness direction of the button body 11 is b, where a is less than b.

[0056] In this embodiment, when the button structure 10 is not installed, the movable end of the limiting part 1212 is raised, and the projected length of the limiting part 1212 in the length direction of the button body 11 is small, causing the limiting part 1212 to be recessed within the button body 11. When the button structure 10 is installed, under the limiting action of the metal stop 122, the limiting part 1212 is flattened, and the extension direction of the limiting part 1212 can be consistent with the extension direction of the button body 11, that is, the movable end of the limiting part 1212 can protrude from the button body 11 along the length direction of the button body 11.

[0057] In some alternative embodiments, such as Figure 2 As shown, along the thickness direction of the button body 11, the height of the connecting part 1211 protruding from the mounting side 111 is H1, and the height of the metal stop 122 protruding from the mounting side 111 is H2, 0≤|H2-H1|≤0.05mm.

[0058] In this embodiment, 0 ≤ |H2-H1| ≤ 0.05 mm, so that the difference between the height of the connecting part 1211 protruding from the mounting side 111 and the height of the metal stop 122 protruding from the mounting side 111 is between 0 and 0.05 mm. In this way, when the button structure 10 is in the installation state, the limiting part 1212 can remain parallel or approximately parallel to the mounting side 111 of the button body 11, which is beneficial to ensuring the stability and reliability of the engagement between the limiting part 1212 and the frame 20.

[0059] For example, the difference between the height of the connecting portion 1211 protruding from the mounting side 111 and the height of the metal stop 122 protruding from the mounting side 111 can be 0, 0.01 mm, 0.02 mm, or 0.05 mm, etc. Specifically, when H2 - H1 = 0, the heights of the connecting portion 1211 protruding from the mounting side 111 and the metal stop 122 protruding from the mounting side 111 are the same, making the limiting portion 1212 parallel to the mounting side 111 of the button structure 10.

[0060] In some alternative embodiments, the extension length of the limiting part 1212 is L1, and the minimum distance from the connecting part 1211 to the end face of the first end 113 along the length direction of the button body 11 is L2, where L1-L2≥0.15mm.

[0061] In this embodiment, the extension length of the limiting part 1212 is L1, and the minimum distance from the connecting part 1211 to the end face of the first end 113 along the length direction of the button body 11 is L2. When the button structure 10 is in the installed state, the dimension of the limiting part 1212 protruding from the end face of the first end 113 along the length direction of the button body 11 is L1-L2, that is, the dimension of the limiting part 1212 engaging with the frame 20 is L1-L2. By controlling L1-L2≥0.15mm, it is easy to ensure the stability and firmness of the engagement between the limiting part 1212 and the frame 20, thereby reducing the risk of the button structure 10 falling off.

[0062] Specifically, the size of the limiting part 1212 that engages with the frame 20 can be designed to be small, so that the button structure 10 occupies less internal space in the electronic device, and can provide more space for other components inside the electronic device.

[0063] Specifically, when the button structure 10 is not installed, the limiting part 1212 and the mounting side 111 of the button body 11 can be arranged at an acute angle; when the button structure 10 is installed, the limiting part 1212 and the mounting side 111 of the button body 11 can be arranged in parallel, and the extension length direction of the limiting part 1212 is consistent with the extension length direction of the button body 11.

[0064] For example, L1-L2 can be equal to 0.15mm, 0.155mm, 0.16mm, 0.18mm, 0.19mm, or 0.2mm, etc.

[0065] In some alternative embodiments, such as Figure 7 As shown, along the length of the button body 11, the minimum distance from the metal stop 122 to the end face of the first end 113 is L3, and the minimum distance from the metal stop 122 to the connecting part 1211 is L4, where L4 > L3. This allows the metal stop 122 to be positioned closer to the first end 113 of the button body 11. In this way, the metal stop 122 can provide better support for the end of the limiting part 1212 that is away from the connecting part, reducing the risk of deformation of the limiting part 1212 and ensuring the reliability of the engagement between the limiting part 1212 and the frame 20.

[0066] Furthermore, the limiting part 1212 may have an abutting area, which abuts against the metal stop 122 when the button structure 10 is in the installed state. It can also be designed so that, along the length of the limiting part 1212, the minimum distance from the abutting area to the connecting part 1211 is greater than the minimum distance from the abutting area to the end of the limiting part 1212 away from the connecting part 1211, so that the metal stop 122 can provide good support for the end of the limiting part 1212 away from the connecting part 1211.

[0067] In some alternative embodiments, the surface of the metal stop 122 away from the assembly side 111 is flat, and the side of the limiting part 1212 facing the metal stop 122 is flat. In this way, when the button structure 10 is in the installed state, the flat side of the metal stop 122 abuts against the flat side of the limiting part 1212, making the contact area between the metal stop 122 and the limiting part 1212 larger. The metal stop 122 can better support the limiting part 1212, thereby improving the reliability of the engagement between the limiting part 1212 and the frame 20.

[0068] In some alternative embodiments, the metal hanger 121 and the metal stop 122 are integrally formed with the button body 11, which makes the button structure 10 stronger and can further improve the structural stability and reliability of the button structure 10 assembled into the frame 20.

[0069] In some alternative embodiments, the button structure 10 may include one or two sets of mounting components 12, such as Figure 1 and Figure 2As shown, the button structure 10 may include two sets of mounting components 12. The mounting components 12 may include metal hangers 121 and metal stops 122. One set of mounting components 12 is disposed near the first end 113 of the button body 11, and the limiting portion 1212 of the metal hanger 121 in the first set of mounting components 12 is inclined toward the first end 113 of the button body 11. The other set of mounting components 12 is disposed near the second end 114 of the button body 11, and the limiting portion 1212 of the metal hanger 121 in the other set of mounting components 12 is inclined toward the second end 114 of the button body 11. The metal stops 122 in the other set of mounting components 12 are disposed along the length direction of the button body 11 between the second end 114 and the connecting portion 1211 in the other set of mounting components 12.

[0070] In this embodiment of the application, when the button structure 10 is installed on the electronic device, the first end 113 of the button body 11 can be engaged with the frame 20 through the limiting part 1212 of one of the mounting components 12, and the second end 114 can be engaged with the frame 20 through the limiting part 1212 of another mounting component 12, so that both ends of the button body 11 can be engaged, and the engagement with the frame 20 is more stable.

[0071] Specifically, two mounting components 12 are arranged at intervals along the length of the button body 11 on the mounting side 111 of the button body 11. In some embodiments, the two mounting components 12 may be mirror-mounted at both ends of the button body 11 along its length, making the button structure 10 more structurally stable and improving the reliability of its assembly with the frame 20.

[0072] Specifically, the two mounting components 12 are mirror images of the button body 11 at both ends along its length, that is, the metal stops 122 of the two mounting components 12 are mirror images of the button body 11 at both ends along its length, and the metal feet 121 of the two mounting components 12 are mirror images of the button body 11 at both ends along its length. Figure 1 As shown, in the left mounting assembly 12, the metal stop 122 is disposed between the first end 113 and the limiting part 1212, and the end of the limiting part 1212 away from the connecting part 1211 is inclined toward the first end 113. In the right mounting assembly 12, the metal stop 122 is disposed between the second end 114 and the limiting part 1212, and the end of the limiting part 1212 away from the connecting part 1211 is inclined toward the second end 114.

[0073] In some optional embodiments, the button structure 10 further includes a pressing member 14 for triggering the button function. The pressing member 14 is connected to the assembly side 111. In the length direction of the button body 11, the pressing member 14 is disposed on the side of the connecting part 1211 away from the first end 113, and the pressing member 14 and the connecting part 1211 are spaced apart.

[0074] In this embodiment, the pressing member 14 and the limiting part 1212 are located on opposite sides of the connecting part 1211, so that they do not interfere with each other. By operating the pressing member 14, the button function can be triggered, which is simple and convenient.

[0075] Specifically, the pressing element 14 can be configured corresponding to the mounting component 12. When there is one mounting component 12, one pressing element 14 can be provided; when there are two mounting components 12, two pressing elements 14 can be provided. Alternatively, the number of pressing elements 14 and mounting components 12 can be designed to be different, and this embodiment does not specifically limit this.

[0076] like Figure 1 and Figure 2 As shown, in some examples, both pressing members 14 are disposed between the connecting portions 1211 of the two mounting components 12, and the pressing members 14 are disposed close to the adjacent connecting portions 1211. In this way, when the first end 113 of the button body 11 is pressed, one button function can be triggered by one pressing member 14, and when the second end 114 of the button body 11 is pressed, another button function can be triggered by the other pressing member 14. The button structure 10 in the embodiments of this application can be used to implement at least two button functions.

[0077] Specifically, the button structure 10 can be a volume button, with one press 14 corresponding to the volume up function and the other press 14 corresponding to the volume down function; or, the button structure 10 can also be a music button, with one press 14 corresponding to the previous track selection function and the other press 14 corresponding to the next track selection function.

[0078] In some optional embodiments, the button structure 10 further includes a support boss 13, which is disposed between the first end 113 and the second end 114, so that the support boss 13 can divide the button body 11 into two parts and act as a fulcrum of a lever, so that both ends of the button body 11 can be pressed, thereby realizing that by pressing both ends of the button body 11, different button functions can be triggered by different pressing members 14 respectively.

[0079] The button structure 10 described in this application embodiment has at least the following advantages:

[0080] In the embodiments of this application, when the button structure is in the installed state, the end of the limiting part away from the connecting part protrudes from the end face of the first end of the button body in the length direction of the button body, so that the part of the limiting part 1212 protruding from the button body 11 can be locked with the frame 20 of the electronic device, realizing the assembly between the button structure 10 and the frame 20 of the electronic device. Since the metal hanging foot 121 has high structural strength, the limiting part 1212 can be locked with the frame 20 more firmly and is not easy to shake, thereby greatly reducing the risk of the button structure 10 falling off.

[0081] Secondly, this application discloses an electronic device including the aforementioned button structure 10, which can be mounted on the electronic device in an installed state.

[0082] Optionally, the electronic device further includes: a frame 20, the frame 20 being provided with a button groove 21 for mounting the button body 11, and a limiting protrusion 22 being provided on the side wall of the button groove 21; one end of the limiting part 1212 away from the connecting part 1211 is engaged with the limiting protrusion 22 through the end face of the first end 113 protruding from the button body 11, thereby restricting the button body 11 from coming out of the button groove 21, so that the button body 11 is sealed in the groove opening of the button groove 21.

[0083] In this embodiment, when the limiting part 1212 is in the first state, it is squeezed into the button groove 21. After the limiting part 1212 abuts against the bottom of the button groove 21, it is squeezed and then switches to the second state. At least a portion of the limiting part 1212 protrudes from the button body 11 and can engage with the limiting protrusion 22, so that the limiting protrusion 22 can restrict the limiting part 1212 from sliding out.

[0084] Specifically, the limiting protrusion 22 and the bottom of the key groove 21 are spaced apart, and the portion of the limiting part 1212 that protrudes from the key body 11 can be accommodated between the limiting protrusion 22 and the bottom of the key groove 21.

[0085] In some alternative embodiments, the electronic device further includes a guide 30, a push-button switch assembly 41, and a circuit board 40. The push-button switch assembly 41 is disposed on the circuit board 40. The frame 20 is provided with a through hole 23 and a mounting groove 24. The circuit board 40 is disposed in the mounting groove 24. One end of the through hole 23 is connected to the push-button groove 21, and the other end of the through hole 23 is connected to the mounting groove 24. The guide 30 is slidably fitted in the through hole 23, with one end opposite to the push-button switch assembly 41 and the other end opposite to the pressing member 14 of the push-button structure 10.

[0086] In this embodiment, when the pressing member 14 presses the guide member 30, the guide member 30 can press and trigger the button switch assembly 41 on the circuit board 40, thereby realizing the button function. Since the guide member 30 and the through hole 23 are in sliding fit, the direction of the pressing force applied to the button switch assembly 41 can be restricted, thereby improving the reliability of triggering the button switch assembly 41.

[0087] In some alternative embodiments, the frame 20 is provided with a clearance hole 25 for the top rod to pass through, and the circuit board 40 is disposed between the clearance hole 25 and the through hole 23; when the circuit board 40 is removed, the clearance hole 25 and the through hole 23 are connected, and the top rod passes through the clearance hole 25 and the through hole 23 to press the guide 30, which can push the button structure 10 out of the button slot 21.

[0088] In this embodiment, when the circuit board 40 is removed, the guide member 30 can be squeezed by passing the push rod through the clearance hole 25 and the through hole 23 in sequence, and then the pressing member 14 can be squeezed through the guide member 30, thereby pushing the button structure 10 out of the button slot 21, which facilitates the replacement of the button structure 10.

[0089] Specifically, when the button structure 10 has a poor feel, instead of scrapping the entire frame 20 assembly, the circuit board 40 can be removed first, such as... Figure 8 As shown, a push rod is used to apply a thrust F2 to the guide 30. When the thrust F2 exceeds the metal shear strength, the connection between the limiting part 1212 and the connecting part 1211 will break, thereby enabling the defective button structure 10 to be removed.

[0090] Specifically, the electronic devices described in the embodiments of this application include, but are not limited to, mobile phones, computers, tablets, etc.

[0091] The electronic device described in this application embodiment can achieve the same beneficial effects as the button structure described above, and will not be repeated here.
