[0001] Cross-reference to related applications

[0002] This application claims priority to Chinese Patent Application No. 202411503998.7, filed on October 25, 2024, entitled “Electronic Device”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application belongs to the field of electronic technology, specifically relating to an electronic device. Background Technology

[0004] Buttons, as the operating mechanism of electronic devices such as mobile phones, are usually located on the side of the electronic device for user operation.

[0005] In the prior art, in order to facilitate the assembly of buttons, a fixing groove is opened on the housing of the electronic device, and a button fixing bracket is installed in the fixing groove so that the button fixing bracket and the button form a snap-fit ​​engagement to fix the button on the housing. However, this arrangement will increase the space occupied by the button and the component that installs the button, which will be detrimental to the arrangement of other components inside the housing.

[0006] Therefore, existing electronic devices use button mounting brackets to fix the buttons, resulting in the buttons and the components that mount the buttons occupying a large amount of space. Summary of the Invention

[0007] The purpose of this application is to provide an electronic device that can solve the problem in related technologies where buttons are fixed by a button fixing bracket, resulting in a large space occupied by the buttons and the components that install the buttons.

[0008] This application provides an electronic device, including: a housing with a button mounting slot, wherein a limiting portion is provided on the wall of the button mounting slot and the limiting portion is disposed near the opening of the button mounting slot; a button including an elastic connecting portion and a keycap body connected to the elastic connecting portion, wherein at least a portion of the keycap body is located outside the housing, at least a portion of the elastic connecting portion is disposed within the button mounting slot, and a snap-fit ​​portion is provided on the elastic connecting portion, wherein the snap-fit ​​portion can engage with the limiting portion in the direction from the elastic connecting portion to the keycap body.

[0009] In this embodiment, the button includes an elastic connecting part and a keycap body connected to the elastic connecting part. At least a portion of the keycap body is located outside the housing so that it can be exposed outside the housing for easy user operation. At least a portion of the elastic connecting part is disposed in the button mounting slot, and a snap-fit ​​part is provided on the elastic connecting part. A limiting part is provided on the groove wall of the button mounting slot of the housing. In the direction from the elastic connecting part to the keycap body, the snap-fit ​​part and the limiting part limit each other. That is, in the direction from the inside to the outside of the housing, the snap-fit ​​part and the limiting part limit each other. In this way, the button can be fixed. Furthermore, since the elastic connecting part is elastic and can deform under force, when assembling the button, the button can be directly installed into the button mounting slot by external pressing, and the snap-fit ​​part and the limiting part limit each other. Therefore, it is not necessary to open a fixing slot on the housing or use a button fixing bracket to fix the button, saving the installation space of the button fixing bracket. This is conducive to the thinning of the housing and provides space for the arrangement of other components inside the housing, thereby facilitating the layout of components inside the electronic device.

Detailed Implementation

[0021] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0022] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0023] The electronic device provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0024] Referring to Figures 1-10, an electronic device provided in this application embodiment may include a housing 600 and a button 200. The housing 600 may be provided with a button mounting groove 110, and a limiting portion 113 may be provided on the groove wall of the button mounting groove 110. The button 200 may include an elastic connecting portion 212 and a keycap body 211 connected to the elastic connecting portion 212. Here, the keycap body 211 may cover the elastic connecting portion 212. At least a portion of the keycap body 211 may be located outside the housing 600, so that the keycap body 211 is exposed outside the housing 600 for user operation; and at least a portion of the elastic connecting part 212 may be disposed in the key mounting groove 110. The elastic connecting part 212 may be provided with a snap-fit ​​part 230. In the direction from the elastic connecting part 212 to the keycap body 211, the snap-fit ​​part 230 may engage with the limiting part 113 for limiting, that is, in the direction from the inside to the outside of the housing 600, the snap-fit ​​part 230 engages with the limiting part 113 for limiting, thus achieving the fixation of the key 200.

[0025] Here, the limiting part 113 is positioned close to the groove of the button mounting slot 110, which helps to reduce the thickness of the button 200, and thus helps to reduce the thickness of the housing 600.

[0026] It should be noted that the housing 600 may include a frame 100 and a back cover. The frame 100 is connected to the back cover to form a space for accommodating components such as batteries and circuit boards of electronic devices. The button mounting slot 110 may be provided on the frame 100.

[0027] In this embodiment, since the elastic connecting part 212 is elastic and can deform under force, when assembling the button 200, the button 200 can be directly installed into the button mounting slot 110 by external pressing, and the snap-fit ​​part 230 and the limiting part 113 are limited and engaged. Therefore, it is not necessary to open a fixing slot on the housing 600 or to use a button fixing bracket to fix the button 200, which saves the installation space of the button fixing bracket, thereby facilitating the thinning of the housing 600 and providing space for the arrangement of other components inside the housing 600, which is beneficial to the layout of components inside the electronic device.

[0028] In an optional embodiment, the snap-fit ​​portion 230 can be a resilient snap-fit ​​portion. This makes it easier to assemble the button 200 into the button mounting slot 110 when assembling the button 200.

[0029] Optionally, the elastic connection portion 212 and the snap-fit ​​portion 230 can be made of the same material, such as thermoplastic polyurethane (TPU), or other elastic materials. Of course, the elastic connection portion 212 and the snap-fit ​​portion 230 can also be made of different materials.

[0030] In an optional embodiment of this application, the housing 600 may be provided with at least two button mounting slots 110, which may include a first button mounting slot 111 and a second button mounting slot 112. The electronic device may include at least two buttons 200, which may include a first button 201 and a second button 202. At least a portion of the elastic connecting portion 212 of the first button 201 may be disposed in the first button mounting slot 111, and at least a portion of the elastic connecting portion 212 of the second button 202 may be disposed in the second button mounting slot 112. In this way, pressing different buttons 200 can enable the electronic device to perform different functions.

[0031] Furthermore, a first limiting part 1131 can be provided on the groove wall of the first key mounting groove 111, and a second limiting part 1132 can be provided on the groove wall of the second key mounting groove 112. A first snap-fit ​​part 231 can be provided on the elastic connecting part 212 of the first key 201, and a second snap-fit ​​part 232 can be provided on the elastic connecting part 212 of the second key 202. In the direction from the elastic connecting part 212 to the keycap body 211, the first snap-fit ​​part 231 can engage with the first limiting part 1131, and the second snap-fit ​​part 232 can engage with the second limiting part 1132. In this way, each key 200 can be fixed without the use of a key fixing bracket, thereby reducing the installation space of each key 200 and allowing the housing 600 to be further thinned.

[0032] Here, the first limiting part 1131 can be set close to the opening of the first button mounting slot 111, and the second limiting part 1132 can be set close to the opening of the second button mounting slot 112. This is beneficial to reduce the thickness of the elastic connection part 212 of the first button 201 and the second button 202, thereby reducing the thickness of the housing 600 and increasing the battery installation space.

[0033] In other embodiments, the housing 600 may have only one button mounting slot 110, and the electronic device may have only one button 200. Of course, the housing 600 may also have at least two button mounting slots 110, and the electronic device may have at least two buttons 200, with limiting portions 113 provided on the groove walls of some of the button mounting slots 110, and snap-fit ​​portions 230 provided on the elastic connecting portions 212 of some of the buttons 200.

[0034] In an optional embodiment, the housing 600 may include a first portion 130 and a second portion 140 connected to the first portion 130. Specifically, the frame 100 of the housing 600 may include the first portion 130 and the second portion 140. At least a portion of the first portion 130 may be disposed opposite to the battery of the electronic device. A first button mounting groove 111 may be disposed on the first portion 130, and a second button mounting groove 112 may be disposed on the second portion 140. Furthermore, in the direction from the battery to the first portion 130, the inner surface of the first portion 130 may be recessed relative to the inner surface of the second portion 140. In this embodiment, at least a portion of the first button mounting groove 111 is disposed opposite to the battery, the second button mounting groove 112 may be misaligned with the battery, and the depth of the first button mounting groove 111 may be less than the depth of the second button mounting groove 112. In this way, the thickness of the first part 130 can be made thinner, so as to provide more installation space for the battery, thereby facilitating the increase of battery volume. Furthermore, the thickness of the second part 140 can be greater than the thickness of the first part 130, so that the second part 140 can provide more installation space for the second button 202, thereby improving the stability of the installation of the second button 202.

[0035] Of course, in the direction from the battery to the first portion 130, the inner side of the first portion 130 may not be recessed relative to the inner side of the second portion 140. Optionally, the inner sides of the first portion 130 and the second portion 140 may be flush, and both the inner sides of the first portion 130 and the second portion 140 may be relatively close to the outer surface of the housing 600, which is more conducive to the thinning of the housing 600.

[0036] Here, the width of the first button mounting slot 111 can be 0.75mm, and in order to meet the actual mass production of electronic devices, the second button mounting slot 112 can be machined by an end mill, and the first button mounting slot 111 can be machined by a saw blade with a smaller machining width.

[0037] In the prior art, the depth of the button mounting groove in the method of fixing the button 200 using a button fixing bracket is 5.3mm; in this embodiment, the depth of the second button mounting groove 112 can be 4.04mm. Therefore, in this embodiment, the battery can be provided with 1.26mm of space in the depth direction of the button mounting groove 110, which greatly enhances the product competitiveness. It should be noted that the depth of the button mounting groove 110 can be the depth of the button mounting groove 110 in the direction from the elastic connecting part 212 to the keycap body 211.

[0038] In an optional embodiment of this application, the electronic device may further include a button circuit board 300. The button circuit board 300 may be disposed within the housing 600, and may include a first circuit board 310 and a second circuit board 320. The first circuit board 310 may be disposed opposite to the first button 201, and a first trigger 351 may be disposed on the first circuit board 310. The first button 201 may trigger the first trigger 351 to enable the electronic device to perform a first function. The second circuit board 320 may be disposed opposite to the second button 202, and a second trigger 352 may be disposed on the second circuit board 320. The second button 202 may trigger the second trigger 352 to enable the electronic device to perform a second function. Here, at least a portion of the first circuit board 310 may be located within the first button mounting slot 111, and at least a portion of the second circuit board 320 may be located within the second button mounting slot 112.

[0039] The distance between the first circuit board 310 and the opening of the first button mounting slot 111 can be smaller than the distance between the opening of the second circuit board 320 and the opening of the second button mounting slot 112. This allows the first circuit board 310 to be closer to the outer surface of the housing 600, avoiding interference with the battery and providing more installation space for the battery.

[0040] In other embodiments, the distance between the first circuit board 310 and the slot of the first button mounting slot 111 may be greater than or equal to the distance between the second circuit board 320 and the slot of the second button mounting slot 112.

[0041] Optionally, the second circuit board 320 may have at least two second triggers 352, and the second button 202 may trigger each of the second triggers 352 respectively. Thus, by triggering each of the second triggers 352 separately by the second button 202, the electronic device can perform different functions. Specifically, the second circuit board 320 may have two second triggers 352. Here, the second button 202 can be a volume button. By pressing different positions of the second button 202, the two second triggers 352 can be triggered respectively, thereby adjusting the volume of the electronic device. Similarly, the first circuit board 310 may also have at least two first triggers 351 to enable the electronic device to perform different functions. Of course, the second circuit board 320 may also have only one second trigger 352, and the first circuit board 310 may also have only one first trigger 351.

[0042] In one embodiment, the first button mounting slot 111 and the second button mounting slot 112 can be connected, and the first circuit board 310 and the second circuit board 320 can be connected as an integrated circuit board through an adapter plate 340. The first circuit board 310 and the second circuit board 320 can be electrically connected. Here, the first circuit board 310 and the second circuit board 320 can be electrically connected to the motherboard of the electronic device through only one electrical connector 330. This helps to reduce the number of electrical connectors 330, thereby simplifying the structure of the electronic device, reducing the space occupied by the electrical connectors 330, and thus increasing the battery installation space.

[0043] In another embodiment, the first button mounting slot 111 and the second button mounting slot 112 may not be connected, and the first circuit board 310 and the second circuit board 320 may be electrically connected to the motherboard of the electronic device through two electrical connectors 330 respectively.

[0044] In an optional embodiment, the electronic device may further include a mounting bracket 400 disposed within the housing 600. The mounting bracket 400 may include a first bracket 410 and a second bracket 420. The first bracket 410 may be connected to the housing 600 and may be connected to a first circuit board 310, serving to support the first circuit board 310. Specifically, the first bracket 410 may be provided with a first receiving groove, and a portion of the first circuit board 310 may be embedded in the first receiving groove and limited in engagement with the groove wall of the first receiving groove to achieve support for the first circuit board 310. The second bracket 420 may be connected to the second circuit board 320 and serve to support the second circuit board 320. Specifically, the second bracket 420 may be provided with a second receiving groove, and a portion of the second circuit board 320 may be embedded in the second receiving groove and limited in engagement with the groove wall of the second receiving groove to achieve support for the second circuit board 320. Here, with the first button mounting slot 111 and the second button mounting slot 112 connected, the first frame 410 and the second frame 420 can be connected into an integrated structure by a connecting plate. This can improve the strength of the fixing frame 400, thereby improving the support strength of the button circuit board 300.

[0045] Furthermore, the distance between the side of the first frame 410 facing away from the opening of the first button mounting slot 111 and the opening of the first button mounting slot 111 can be smaller than the distance between the side of the second frame 420 facing away from the opening of the second button mounting slot 112 and the opening of the second button mounting slot 112. This avoids interference between the first frame 410 and the battery and provides more installation space for the battery.

[0046] Of course, the distance between the side of the first frame 410 facing away from the opening of the first button mounting slot 111 and the opening of the first button mounting slot 111 can also be greater than or equal to the distance between the side of the second frame 420 facing away from the opening of the second button mounting slot 112 and the opening of the second button mounting slot 112.

[0047] Optionally, the mounting bracket 400 can be made of a rigid material for better assembly. Here, the mounting bracket 400 can be made of polycarbonate (PC) material, but of course, the mounting bracket 400 can also be made of other rigid materials.

[0048] In an optional embodiment, the electronic device may further include a first reinforcing plate 510. The first reinforcing plate 510 may be disposed within and connected to the housing 600. The first reinforcing plate 510 may be located on the side of the first circuit board 310 opposite to the first button 201, and the first reinforcing plate 510 may be in contact with the first circuit board 310. In this way, the first reinforcing plate 510 can further support and fix the first circuit board 310, thereby improving the stability of the fixation of the first circuit board 310.

[0049] The electronic device may also include a second reinforcing plate 520, which may be disposed within and connected to the housing 600. The second reinforcing plate 520 may be located on the side of the second circuit board 320 opposite to the second button 202, and may be in contact with the second circuit board 320. In this way, the second reinforcing plate 520 can further support and fix the second circuit board 320, thereby improving the stability of the second circuit board 320.

[0050] The distance between the first reinforcing plate 510 and the opening of the first button mounting slot 111 can be smaller than the distance between the opening of the second reinforcing plate 520 and the opening of the second button mounting slot 112. This avoids interference between the first reinforcing plate 510 and the battery and provides more installation space for the battery.

[0051] Of course, the distance between the first reinforcing plate 510 and the slot of the first button mounting groove 111 can also be greater than or equal to the distance between the second reinforcing plate 520 and the slot of the second button mounting groove 112.

[0052] Optionally, when the first reinforcing plate 510 and the second reinforcing plate 520 are close to the antenna component of the electronic device, the first reinforcing plate 510 and the second reinforcing plate 520 can be made of glass fiber epoxy resin material (Flame-Retardant). 4. The first reinforcing plate 510 and the second reinforcing plate 520 are made of FR4 to avoid electromagnetic interference from the button circuit board 300 to the antenna component. Here, the minimum thickness of the first reinforcing plate 510 and the second reinforcing plate 520 can be 0.25mm. Of course, the first reinforcing plate 510 and the second reinforcing plate 520 can also be made of other materials capable of isolating electromagnetic interference. When the first reinforcing plate 510 and the second reinforcing plate 520 are far from the antenna component of the electronic device, the first reinforcing plate 510 and the second reinforcing plate 520 can also be made of stainless steel. This ensures the strength of the first reinforcing plate 510 and the second reinforcing plate 520 while allowing for a thinner thickness, thereby further increasing the battery installation space. Here, the minimum thickness of the first reinforcing plate 510 and the second reinforcing plate 520 can be 0.15mm. Of course, the first reinforcing plate 510 and the second reinforcing plate 520 can also be made of other materials. It should be noted that the specific material used for the first reinforcing plate 510 and the second reinforcing plate 520 can be determined based on whether it will affect the performance of the antenna components.

[0053] Furthermore, the button circuit board 300 described above may include at least two circuit boards, including the first circuit board 310 and the second circuit board 320 described above. Here, each circuit board may correspond one-to-one with each button 200, and each circuit board is provided with a trigger 350. Each button 200 can trigger each trigger 350 to enable the electronic device to perform different functions.

[0054] Furthermore, the mounting bracket 400 described above may also include at least two brackets, which may include the first bracket 410 and the second bracket 420 described above. Here, each bracket is connected to each circuit board to support each circuit board. Of course, the electronic device may also include at least two reinforcing plates 500, which may include a first reinforcing plate 510 and a second reinforcing plate 520. Each reinforcing plate 500 may be connected to each circuit board to further support and strengthen each circuit board.

[0055] In an optional embodiment of this application, the button 200 may further include a resilient striking post 220, and the electronic device may further include a button circuit board 300 and a mounting bracket 400 for supporting the button circuit board 300. Both the button circuit board 300 and the mounting bracket 400 may be disposed within the housing 600. A trigger 350 may be disposed on the button circuit board 300, and a clearance opening 401 opposite to the trigger 350 may be disposed on the mounting bracket 400 to avoid the striking post 220. The first end of the striking post 220 may be connected to the resilient connecting part 212, and the second end of the striking post 220 may pass through the housing 600 and the clearance opening 401 and may contact the trigger 350 to trigger the trigger 350, thereby enabling the electronic device to perform the corresponding function. Optionally, the button 200 may include at least two striking posts 220, and the button circuit board 300 may be provided with at least two triggers 350. The first end of each striking post 220 may be connected to the elastic connection part 212, and the second end of each striking post 220 may pass through the housing 600 and the clearance opening 401 to contact the trigger 350, so that the electronic device can perform different functions.

[0056] In this embodiment, the trigger 350 can be a micro switch, a photoelectric switch, or other components capable of triggering.

[0057] Here, the mounting bracket 400 is provided with a clearance opening 401 opposite to the trigger 350, which allows the second end of the striking post 220 to directly contact the trigger 350. Compared with the method of contacting the trigger 350 through the elastic part on the mounting bracket 400, the elastic part is reduced, which further reduces the space occupied by the button 200, the circuit board and the mounting bracket 400, so as to provide more installation space for the battery, thereby helping to increase the size of the battery.

[0058] In other embodiments, the bracket 400 for supporting the button circuit board 300 may be provided with an elastic part, which may be located between the trigger 350 and the striking post 220, and the striking post 220 may drive the elastic part to contact the trigger 350 to trigger the trigger 350.

[0059] In an optional embodiment, the striking post 220 may include an elastic post 221 and a waterproof post 222. The first end of the elastic post 221 may be connected to the elastic connecting part 212, and the first end of the waterproof post 222 may be connected to the second end of the elastic post 221. The second end of the waterproof post 222 may pass through the housing 600 and the clearance opening 401 and may contact the trigger 350. In this way, by providing the elastic post 221 between the waterproof post 222 and the elastic connecting part 212, the pressing feel of the button 200 can be further improved, thereby enabling the button 200 to have a good pressing feel. At the same time, the strength and hardness of the striking post 220 can be guaranteed so that the striking post 220 can trigger the trigger 350.

[0060] Here, the waterproof column 222 can be sealed with the housing 600, thus preventing external moisture or dust from entering the housing 600 through the gap between the waterproof column 222 and the housing 600.

[0061] Of course, the striking post 220 may also include only the waterproof post 222. Specifically, the first end of the waterproof post 222 is connected to the elastic connection part 212, and the second end of the waterproof post 222 passes through the housing 600 and the clearance opening 401 and can contact the trigger 350.

[0062] It should be noted that the button mounting slot 110 may include a first mounting slot 114 and a second mounting slot 115. A portion of the elastic connecting part 212 may be disposed within the first mounting slot 114, and the limiting part 113 may be disposed on the slot wall of the first mounting slot 114. At least a portion of the button circuit board 300, the fixing bracket 400, and the reinforcing plate 500 may all be disposed within the second mounting slot 115. To prevent moisture or dust from entering the second mounting slot 115 and damaging the button circuit board 300, a waterproof part 120 may be provided between the first mounting slot 114 and the second mounting slot 115. Here, the waterproof part 120 may be part of the housing 600, and the second end of the waterproof column 222 may pass through the waterproof part 120 and extend into the second mounting slot 115 to contact the trigger 350.
