Description

Technical Field

[0001] This application relates to the field of electronic technology, and in particular to a button assembly and an electronic device. Background Technology

[0002] Electronic devices typically have buttons for adjusting volume or controlling power. When a user needs to perform the function corresponding to a button, they press the button to trigger the button switch, thus realizing the corresponding function.

[0003] In related technologies, the end of the button that contacts the push-button switch penetrates through a through-hole on the side frame of the mid-frame to enter the interior of the electronic device, thus enabling the button to trigger the push-button switch inside the device. However, external water can easily enter the electronic device through the gap between the button and the through-hole on the side frame, meaning that this assembly method of the button and mid-frame results in lower waterproof performance of the electronic device. Summary of the Invention

[0014] Optionally, the elastic element is non-transparent.

[0015] Optionally, the keycap has a second groove on the side facing the support member;

[0016] The support member includes a body portion, at least one first overlapping portion and at least one second overlapping portion, wherein the first overlapping portion and the second overlapping portion are located on opposite sides of the body portion and both extend away from the body portion.

[0017] The first overlapping portion and the second overlapping portion abut against the end face of the top of the second groove, so that the body portion is suspended in the second groove, and the adhesive is located in the gap formed between the body portion and the inner wall of the second groove.

[0018] Optionally, the support member includes two first overlapping portions and two second overlapping portions, with the first overlapping portions and the second overlapping portions corresponding to each other and arranged opposite to each other.

[0019] Optionally, the second groove includes a third groove wall and a fourth groove wall disposed opposite to each other, the third groove wall having a first protrusion extending toward the bottom of the first groove, and the fourth groove wall having a second protrusion extending toward the bottom of the first groove.

[0020] The first protrusion is engaged between the two first overlapping portions, and the second protrusion is engaged between the two second overlapping portions.

[0021] Optionally, the main body is provided with a first snap-fit ​​portion on the side facing the bottom of the first groove;

[0022] The abutment portion is provided with a second snap-fit ​​portion on the side opposite to the bottom of the first groove, wherein the first snap-fit ​​portion and the second snap-fit ​​portion are snap-fitted together.

[0023] Optionally, the body portion has a through groove on the side facing the bottom of the first groove, and the through groove extends along the length direction of the body portion;

[0024] The elastic element also includes a connecting part, and the two ends of the connecting part are respectively connected to the abutting part, and the connecting part is inserted into the through groove.

[0025] Optionally, the bottom of the through groove is provided with a third snap-fit ​​part, and the connecting part is provided with a fourth snap-fit ​​part. The third snap-fit ​​part and the fourth snap-fit ​​part are snap-fitted together, and the fourth snap-fit ​​part abuts against the guide member. The two abutting parts are symmetrically arranged about the third snap-fit ​​part.

[0026] Optionally, the button further includes two elastic support members, which are symmetrically arranged about the axis of the guide member. The two sides of the elastic support members abut against the side of the pressing member facing the bottom of the first groove and the bottom of the first groove, respectively.

[0027] Optionally, the button assembly further includes a button switch;

[0028] The support member includes a support surface that intersects with the outer side surface. The support surface is provided with a third groove.

[0029] The push-button switch is located within the third groove and is positioned opposite to the guide member.

[0030] Secondly, embodiments of this application also provide an electronic device, which includes a button assembly as described in any one of the embodiments of the first aspect of this application.

[0031] The button assembly provided in this application includes a carrier and a button. The button includes a pressing member, a guide member, and a sealing member. The outer surface of the carrier is provided with a first groove, the groove wall of which has a first recess. The pressing member includes an abutting portion protruding towards the bottom of the first groove, and the side wall of the abutting portion is provided with a first limiting portion, which extends into the first recess through the first groove. Thus, when the pressing member moves, it will not detach from the carrier due to the limiting effect of the first recess on the first limiting portion. The carrier is provided with a first through hole. One end of the guide member of the button abuts against the pressing member, and the other end extends into the carrier through the first through hole. Thus, when the pressing member is pressed, it can push the guide member to realize the pressing function. A sealing member is sleeved on the guide member, and the sealing member abuts against the wall of the first through hole, so that the sealing member can seal the first through hole. Because the pressing component moves within the first groove rather than inside the carrier, and the first through hole connecting the first groove and the carrier is sealed by a sealant, external water cannot flow into the carrier through the gap between the pressing component and the first groove. In other words, the button assembly provided in this application embodiment has strong waterproof performance. Attached Figure Description

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0047] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0048] Unless otherwise defined, all technical terms used in the embodiments of this application have the same meaning as commonly understood by those skilled in the art.

[0049] To make the technical solutions and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0050] Combination Figure 1 and Figure 2 As shown, this application embodiment provides a button assembly, which includes a carrier 100 and a button 200. It should be noted that the carrier 100 in this application embodiment can be, for example, a structure such as the mid-frame of an electronic device.

[0051] The outer surface 110 of the support member 100 is provided with a first groove 111, the bottom of the first groove 111 is provided with a first through hole 112, and the groove wall of the first groove 111 has a first recess 113. In some embodiments, a section of the groove wall of the first groove 111 near the bottom of the first groove 111 has a first recess 113.

[0052] The button 200 includes a pressing member 210, a guide member 220, and a sealing member 230. The pressing member 210 includes an abutting portion 211 protruding towards the bottom of the first groove 111. A first limiting portion 212 is provided on the side wall of the abutting portion 211, and the first limiting portion 212 extends into the first recess 113 through the first groove 111. It should be noted that, due to the limiting effect of the first recess 113 on the first limiting portion 212, the abutting portion 211 can be prevented from disengaging from the first recess 113, thereby preventing the abutting portion 211 from disengaging from the support member 100, and thus the button 200 will not disengage from the support member 100.

[0053] One end of the guide member 220 abuts against the pressing member 210, and the other end extends into the carrier member 100 through the first through hole 112. The sealing member 230 is sleeved on the guide member 220 and abuts against the wall of the first through hole 112. The pressing member 210 can move towards or away from the bottom of the first groove 111 within the first groove. It should be noted that when the pressing member 210 is pressed, it can move towards the bottom of the first groove 111 until the end face of the abutting part 211 abuts against the bottom of the first groove 111, simultaneously pushing the guide member 220 into the carrier member 100 to realize the function of the button 200. After the pressure is released, the pressing member 210 returns to its initial position, and the guide member 220 also returns to its original position simultaneously.

[0054] It should be noted that, since the pressing member 210 moves within the first groove 111 rather than within the support member 100, and the first through hole 112 is sealed by the sealing member 230, external water cannot flow into the support member 100 from the gap between the pressing member 210 and the first groove 111. In other words, the button assembly provided in this application embodiment has strong waterproof performance.

[0055] The following is in conjunction with the appendix Figures 1 to 7 The various components and functions of the button assembly provided in the embodiments of this application will be described in more detail.

[0056] like Figure 2As shown, in some embodiments, the first groove 111 includes a first groove wall 114 and a second groove wall 115 disposed opposite to each other, and the first groove wall 114 and the second groove wall 115 are respectively provided with a first recess 113. It is understood that the first recess 113 of the first groove wall 114 is recessed away from the second groove wall 115, and the first recess 113 of the second groove wall 115 is recessed away from the first groove wall 114. The first recess 113 may be provided in a section of the first groove wall 114 near the bottom of the first groove 111, and the first recess 113 may be provided in a section of the second groove wall 115 near the bottom of the first groove 111.

[0057] The abutment portion 211 includes opposing first sidewalls 213 and second sidewalls 214. The first sidewall 213 faces the first groove wall 114, and the second sidewall 214 faces the second groove wall 115. First limiting portions 212 are respectively connected to the first sidewalls 213 and 214, and the first limiting portions 212 extend into the corresponding first recesses 113. It should be noted that the first sidewalls 213 and 214 can, for example, be arranged opposite each other in the thickness direction of the support member 100. The first limiting portions 212 can reciprocate within the first recesses 113 in a direction parallel to the pressing direction. By providing first limiting portions 212 on the opposing two sidewalls of the abutment portion 211, the force on the abutment portion 211 can be more balanced, thus balancing the force on the pressing member 210 and preventing the pressing member 210 from shifting or shaking during the pressing process.

[0058] like Figure 2 As shown, in some embodiments, when the pressing member 210 is not pressed, the end face of the first recess 113 is at a predetermined distance from the bottom of the first groove 111. It should be understood that this predetermined distance can provide the pressing member 210 with movement space, so that the pressing member 210 can be pressed to move toward the bottom of the first groove 111 and push the guide member 220.

[0059] Combination Figure 3 , Figure 4 and Figure 5As shown, in some embodiments, the pressing member 210 includes a keycap 240, a support member 250, and an elastic member 260. The side of the support member 250 facing away from the bottom of the first groove 111 is connected to the keycap 240 via an adhesive member 300, and the side of the support member 250 facing the bottom of the first groove 111 is connected to the elastic member 260. The elastic member 260 includes an abutment portion 211. A portion of the orthographic projection of the support member 250 onto the keycap 240 coincides with the orthographic projection of the elastic member 260 onto the keycap, while another portion does not coincide with the orthographic projection of the elastic member 260 onto the keycap. The support member 250 is transparent. It should be noted that the elastic member 260 is elastic; when the pressing member 210 is pressed, the elastic member 260 undergoes elastic deformation under the pressure of the keycap 240 pointing towards the bottom of the first groove 111. Upon release of pressure, the elastic element 260 recovers its initial state, moving the keycap 240 and support element 250 back to their initial positions. The support element 250 supports the elastic element 260, preventing excessive deformation. The keycap 240 protects both the support element 250 and the elastic element 260, enhancing the aesthetics of the key assembly. The adhesive element 300 can be, for example, glue, bonding the keycap 240 and support element 250 together using a dispensing process. It is understood that the keycap 240 can be, for example, made of metal, the support element 250 can be, for example, made of plastic, and the elastic element 260 can be, for example, made of silicone. It should be understood that because the support 250 is made transparent, when assembling the key assembly, the bonding status of the adhesive 300 to the keycap 240 and the support 250 can be observed through the support 250, as well as whether the adhesive 300 is evenly distributed between the keycap 240 and the support 250. This can prevent the support 250 from falling off the keycap 240 due to inadequate bonding of the adhesive 300, thus ensuring the reliability of the bonding between the support 250 and the keycap 240.

[0060] like Figure 3 As shown, in some embodiments, the elastic element 260 is opaque. Because the elastic element 260 is opaque, it is easier to inspect for defects in the elastic element 260 before assembly, allowing for faster identification of whether the elastic element 260 is a good product. This improves assembly efficiency and increases the product yield. It should be noted that the elastic element 260 and the support element 250 can be manufactured using a two-color injection molding process.

[0061] like Figure 5As shown, in some embodiments, the size of the elastic member 260 is smaller than the size of the support member 250 along the length of the key assembly, and the center position of the elastic member 260 coincides with the center position of the support member 250. With this configuration, the elastic member 260 cannot cover both ends of the support member 250 along its length. Therefore, when the keycap 240 is bonded to the support member 250 using an adhesive dispensing process, it is possible to observe through the support member 250 whether there is glue filling between both ends of the support member 250 and the inner wall of the second groove 241. This ensures the reliability of the bonding between the adhesive member 300 and the support member 250, prevents the support member 250 from detaching from the keycap 240, and improves the reliability of the key assembly.

[0062] like Figure 5 As shown, in some embodiments, the support 250, the elastic member 260 and the keycap 240 are symmetrically arranged about the axis of the guide 220, which ensures that the pressing member 210 is subjected to balanced force, so that the user can push the pressing member 210 smoothly and the pressing member 210 is not easy to deviate or wobble.

[0063] Combination Figure 3 and Figure 4As shown, in some embodiments, the keycap 240 has a second groove 241 on the side facing the support member 250. The support member 250 includes a body portion 251, at least one first overlapping portion 252, and at least one second overlapping portion 253. The first overlapping portion 252 and the second overlapping portion 253 are located on opposite sides of the body portion 251 and both extend away from the body portion 251. The first overlapping portion 252 and the second overlapping portion 253 abut against the end face of the top of the groove of the second groove 241, so that the body portion 251 is suspended in the second groove 241, and the adhesive member 300 is located in the gap formed between the body portion 251 and the inner wall of the second groove 241. It should be noted that by utilizing the first overlapping portion 252 and the second overlapping portion 253, it can be ensured that the main body portion 251 is suspended within the second groove 241. This ensures that a predetermined gap is left between the wall surface of the main body portion 251 facing the second groove 241 and the inner wall of the second groove 241 to accommodate the adhesive 300. Furthermore, it ensures that the main body portion 251 provides appropriate pressure to the adhesive 300, preventing the adhesive 300 from overflowing due to excessive pressure or failing to properly bond the main body portion 251 and the keycap 240 due to insufficient pressure. For example, if the adhesive 300 is glue, the process of assembling the support 250 and the main body portion 251 using a dispensing process is as follows: apply glue to the bottom of the groove 241, then gradually insert the main body portion 251 into the second groove 241 and squeeze the glue until the first overlapping portion 252 and the second overlapping portion 253 abut against the top of the groove 241. At this time, the glue is squeezed by the body part 251 and flows into the gap between the body part 251 and the inner wall of the second groove 241. After the glue solidifies, the body part 251 and the keycap 240 can be stably bonded together, that is, the keycap 240 and the support member 250 can be stably bonded together. It should be noted that by using a double-shot injection molding process to make an integral elastic member 260 and support member 250, and using a dispensing process to bond the support member 250 to the keycap 240, the manufacturing cost of the key assembly can be reduced.

[0064] like Figure 5 As shown, in some embodiments, the support member 250 includes two first overlapping portions 252 and two second overlapping portions 253, which are corresponding one-to-one and arranged opposite each other. This ensures that the forces on both sides of the body portion 251 are balanced, thereby keeping the surface of the body portion 251 facing the bottom of the second groove 241 in a horizontal state. This allows the adhesive 300 between the body portion 251 and the second groove 241 to be distributed more evenly, improving the reliability of the connection between the support member 250 and the keycap 240.

[0065] Combination Figure 3 and Figure 5As shown, in some embodiments, the second groove 241 includes a third groove wall 242 and a fourth groove wall 243 disposed opposite to each other. The third groove wall 242 has a first protrusion 244 extending toward the bottom of the first groove 111, and the fourth groove wall 243 has a second protrusion 245 extending toward the bottom of the first groove 111. The first protrusion 244 is engaged between two first overlapping portions 252, and the second protrusion 245 is engaged between two second overlapping portions 253. It can be understood that the first protrusion 244 can position the first overlapping member, and the second protrusion 245 can position the second overlapping portion 253, thereby facilitating the assembly of the keycap 240 and the support member 250 and improving assembly efficiency. At the same time, the opposite arrangement of the first protrusion 244 and the second protrusion 245 can also provide a clamping effect on the support member 250, so as to better position the support member 250.

[0066] Combination Figure 3 and Figure 6 As shown, in some embodiments, a first engaging portion 254 is provided on the side of the body portion 251 facing the bottom of the first groove 111. A second engaging portion 215 is provided on the side of the abutment portion 211 opposite to the bottom of the first groove 111, wherein the first engaging portion 254 and the second engaging portion 215 engage with each other. It should be noted that either the first engaging portion 254 or the second engaging portion 215 is a protrusion, and the other is a groove that matches the shape of the protrusion.

[0067] Combination Figure 3 , Figure 4 and Figure 6 As shown, in some embodiments, the first engaging portion 254 is a protrusion, and the second engaging portion 215 is a slot. A second limiting portion 255 and a third limiting portion 256 are connected to opposite sides of the first engaging portion 254, extending away from the first engaging portion 254. A second recess 218 and a third recess 219 are respectively provided on opposite sides of the inner wall of the second engaging portion 215, wherein the second limiting portion 255 engages with the second recess 218, and the third limiting portion 256 engages with the third recess 219. It can be understood that the limiting effect of the second recess 218 and the third recess 219 prevents the first engaging portion 254 and the second engaging portion 215 from disengaging from the elastic member 260, thereby improving the stability of the connection between the support member 250 and the elastic member 260.

[0068] Combined Figure 3 and Figure 4As shown, in some embodiments, the body portion 251 has a through groove 216 on the side facing the bottom of the first groove 111, and the through groove 216 extends along the length direction of the body portion 251. The elastic member 260 also includes a connecting portion 261, with abutment portions 211 connected to both ends of the connecting portion 261, and the connecting portion 261 is engaged in the through groove 216. It should be noted that the through groove 216 can position and limit the connecting portion 261.

[0069] Combination Figure 3 and Figure 4 As shown, in some embodiments, the top surface of the through groove 216, the surface of the connecting portion 261 facing the bottom of the first groove 111, the surface of the first overlapping portion 252 facing away from the second groove 241, the surface of the second overlapping portion 253 facing away from the second groove 241, the end faces of the first protrusion 244, and the end faces of the second protrusion 245 are flush. It should be noted that when the connecting portion 261 is inserted into the through groove 216, the support member 250 and the elastic member 260 are assembled as one unit. Then, the assembly fixture moves the elastic member 260 and the support member 250 toward the second groove 241 to gradually extend the body portion 251 into the second groove 241. When the assembly fixture abuts against the end faces of the first protrusion 244 and the second protrusion 245, the assembly fixture stops pressing down on the support member 250. That is, the first protrusion 244 and the second protrusion 245 can position the body portion 251 within the second groove 241. With this configuration, during assembly, the main body 251 can be controlled to extend into a preset position within the second groove 241 to ensure that a preset size gap is left for the adhesive 300, so that the main body 251 can provide appropriate compressive force to the adhesive 300.

[0070] Combination Figure 3 and Figure 6 As shown, in some embodiments, the bottom of the through groove 216 is provided with a third engaging portion 217, and the connecting portion 261 is provided with a fourth engaging portion 262. The third engaging portion 217 and the fourth engaging portion 262 engage with each other, and the fourth engaging portion 262 abuts against the guide member 220. The two abutting portions 211 are symmetrically arranged about the third engaging portion 217. It should be noted that either the third engaging portion 217 or the fourth engaging portion 262 is a protrusion, and the other is a groove matching the shape of the protrusion. For example... Figure 3 and Figure 6 As shown, the third latching part 217 is a protrusion, and the fourth latching part 262 is a slot that matches the shape of the protrusion. The third latching part 217 and the fourth latching part 262 make it easier to flexibly fix the main body part 251 and the support part together.

[0071] Combination Figure 3 and Figure 4As shown, in some embodiments, the button 200 further includes two elastic support members 270. The two elastic support members 270 are symmetrically arranged about the axial direction of the guide member 220. The two sides of the elastic support members 270 abut against the side of the pressing member 210 facing the bottom of the first groove 111 and the bottom of the first groove 111, respectively. It should be noted that the elastic support members 270 are elastic. After the pressing force on the pressing member 210 is released, the elastic restoring force of the elastic support members 270 can make the pressing member 210 more easily and quickly return to its original position. By symmetrically arranging the two elastic support members 270, it can be ensured that the pressing member 210 is subjected to balanced force at both ends, and that the pressing member 210 will not wobble or tilt when the user presses it. It should be noted that even when the pressing member 210 is not pressed, it still provides a small compressive force to the elastic support member 270, which is in a deformed state. Furthermore, there is a certain pre-compression between the first limiting part 212 and the inner wall of the first recessed part 113, ensuring that the pressing member 210 remains fixed on the carrier member 100 without any shaking or other issues. This also ensures that the user's feel when pressing the pressing member 210 is not weak. Simultaneously, it allows the pressing member 210 to have excellent elastic feedback, providing a good tactile experience and improving the user experience.

[0072] Combination Figure 3 and Figure 4 As shown, in some embodiments, the surface of the elastic support 270 facing away from the bottom of the first groove 111 abuts against the surface of at least a portion of the connecting portion 261 facing the bottom of the first groove 111 and the top of at least a portion of the through groove 216. This better prevents the connecting portion 261 from disengaging from the through groove 216, improving the reliability of the button assembly.

[0073] Combination Figure 1 and Figure 7 As shown, in some embodiments, the button assembly further includes a button switch 400. The carrier 100 includes a carrier surface 120 intersecting the outer surface 110. The carrier surface 120 has a third groove 121. The two ends of the first through hole 112 respectively penetrate the bottom of the first groove 111 and the wall of the third groove 121 near the first groove 111. The button switch 400 is located within the third groove 121 and is disposed opposite to the guide member 220. It should be noted that the guide member 220 is disposed opposite to the pressing portion on the button switch 400, so that when the pressing member 210 pushes the guide member 220 inward, the button switch 400 can be accurately pressed to achieve the corresponding function of the button switch 400.

[0074] Combination Figure 1 and Figure 7As shown, in some embodiments, the button assembly further includes a button bracket 500, which is located within the third groove 121 and presses the button switch 400 against the groove wall of the third groove 121 away from the guide member 220. It should be understood that the button bracket 500 can more stably fix the button switch 400 within the third groove 121, ensuring that the button switch 400 does not shift, thus improving the reliability of the button assembly.

[0075] As can be seen from the above, the button assembly provided in this application embodiment has high water resistance and reliability, which can improve the user's pressing feel.

[0076] Secondly, this application also provides an electronic device, which includes a button assembly as described in any one of the embodiments of the first aspect of this application. It should be noted that the composition and function of the button assembly in the electronic device are the same as those of any button assembly provided in the first aspect of this application, and therefore will not be repeated here. It should be understood that because the button assembly has strong waterproof performance, external water flow is less likely to enter the electronic device through the button assembly, thereby improving the waterproof performance of the electronic device.

[0077] In this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The term "multiple" refers to two or more unless otherwise expressly defined.

[0078] Other embodiments of this application will readily occur to those skilled in the art upon consideration of the specification and practice of the application disclosed herein. This application is intended to cover any variations, uses, or adaptations of this application that follow the general principles of this application and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only.

[0079] It should be understood that this application is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this application is limited only by the appended claims.
