In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0012] The electronic device provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0013] refer to Figure 1-Figure 10An electronic device provided in an embodiment of the present application may include a housing 600 and a key 200.

The key 200 may include an elastic connection portion 212 and a key cap body 211 connected to the elastic connection portion 212, and here, the key cap body 211 may cover the elastic connection portion 212. At least part of the keycap body 211 can be located outside the shell 600, so that the keycap body 211 is exposed outside the shell 600 to facilitate user operation; and, at least part of the elastic connecting part 212 can be arranged in the key mounting groove 110, and a clamping part 230 can be arranged on the elastic connecting part 212. In the direction from the elastic connecting part 212 to the keycap body 211, the clamping part 230 can cooperate with the limiting part 113 to limit the position, that is, in the direction from the inside to the outside of the shell 600, the clamping part 230 cooperates with the limiting part 113 to limit the position, so that the key 200 can be fixed.

[0014] Here, the limiting portion 113 is disposed close to the notch of the key installation slot 110 , which is beneficial to reducing the thickness of the key 200 and further to reducing the thickness of the housing 600 .

[0015] 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 enclose a space for accommodating components such as a battery and a circuit board of the electronic device, and the button mounting groove 110 may be provided on the frame 100 .

[0016] In the embodiment of the present application, since the elastic connecting portion 212 is elastic and can be deformed under force, when assembling the key 200, the key 200 can be directly installed in the key mounting groove 110 by external pressing, and the clamping portion 230 is limitedly cooperated with the limiting portion 113, so there is no need to open a fixing groove on the shell 600 and there is no need to use a key fixing bracket to fix the key 200, which saves the installation space of the key fixing bracket, and is conducive to thinning the shell 600, providing space for the arrangement of other components inside the shell 600, which is beneficial to the layout of components inside the electronic device.

[0017] In an optional embodiment, the clamping portion 230 may be an elastic clamping portion. In this way, when assembling the button 200 , it is more convenient to assemble the button 200 into the button installation slot 110 .

In this way, each key 200 can be fixed without using a key fixing bracket, thereby reducing the installation space of each key 200, so that the housing 600 can be further thinned.

[0021] Here, the first limiting portion 1131 can be set close to the notch of the first button mounting groove 111, and the second limiting portion 1132 can be set close to the notch of the second button mounting groove 112, which is beneficial to thinning the thickness of the elastic connecting portion 212 of the first button 201 and the second button 202, and then to thinning the shell 600, so as to increase the installation space of the battery.

[0022] In other embodiments, the housing 600 may be provided with only one key installation slot 110, and the electronic device may include only one key 200. Of course, the housing 600 may be provided with at least two key installation slots 110, and the electronic device may include at least two keys 200, and only some of the key installation slots 110 may be provided with the limiting portion 113 on the slot wall, and some of the keys 200 may be provided with the clamping portion 230 on the elastic connection portion 212.

[0023] 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, wherein at least a portion of the first portion 130 may be disposed opposite to a battery of the electronic device, the first button mounting groove 111 may be disposed on the first portion 130, the second button mounting groove 112 may be disposed on the second portion 140, and, in a direction from the battery to the first portion 130, the inner side surface of the first portion 130 may be recessed relative to the inner side 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 disposed offset from 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 to further provide a larger installation space for the battery, which is beneficial to increase the volume of the battery, and the thickness of the second part 140 can be made greater than the thickness of the first part 130, so that the second part 140 can provide a larger installation space for the second button 202, which is beneficial to improve the stability of the installation of the second button 202.

[0024] Of course, in the direction from the battery to the first part 130, the inner side surface of the first part 130 may not be recessed relative to the inner side surface of the second part 140. Optionally, the inner side surfaces of the first part 130 and the second part 140 may be flush, and the inner side surfaces of the first part 130 and the second part 140 are both closer to the appearance surface of the shell 600, which is more conducive to thinning the shell 600.

It should be noted that the depth of the key installation groove 110 can be the depth of the key installation groove 110 in the direction from the elastic connecting portion 212 to the keycap body 211.

[0027] In an optional embodiment of the present application, the electronic device may further include a key circuit board 300, which may be disposed in the housing 600, and may include a first circuit board 310 and a second circuit board 320, wherein the first circuit board 310 may be disposed opposite to the first key 201, and a first triggering member 351 may be disposed on the first circuit board 310, and the first key 201 may trigger the first triggering member 351, so that the electronic device implements a first function; the second circuit board 320 may be disposed opposite to the second key 202, and a second triggering member 352 may be disposed on the second circuit board 320, and the second key 202 may trigger the second triggering member 352, so that the electronic device implements a second function.

[0028] The distance between the first circuit board 310 and the notch of the first button installation groove 111 may be smaller than the distance between the second circuit board 320 and the notch of the second button installation groove 112. In this way, the first circuit board 310 can be closer to the appearance surface of the housing 600 to avoid interference with the battery, and a larger installation space can be provided for the battery.

[0029] In other embodiments, the distance between the first circuit board 310 and the notch of the first button mounting slot 111 may also be greater than or equal to the distance between the second circuit board 320 and the notch of the second button mounting slot 112 .

[0030] Optionally, at least two second triggering members 352 may be provided on the second circuit board 320, and the second button 202 may trigger each second triggering member 352 respectively. In this way, by triggering each second triggering member 352 respectively by the second button 202, the electronic device can realize different functions. Specifically, two second triggering members 352 may be provided on the second circuit board 320, where the second button 202 may be a volume button, and the two second triggering members 352 may be triggered respectively by pressing different positions of the second button 202, thereby increasing or decreasing the volume of the electronic device. Similarly, at least two first triggering members 351 may also be provided on the first circuit board 310, so that the electronic device can realize different functions.

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 mainboard of the electronic device only through one electrical connector 330. This can help reduce the number of electrical connectors 330, thereby simplifying the structure of the electronic device and reducing the space occupied by the electrical connector 330, which is beneficial to increase the installation space of the battery.

[0032] 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 mainboard of the electronic device through two electrical connectors 330 , respectively.

Here, when the first button mounting groove 111 and the second button mounting groove 112 are connected, the first frame 410 and the second frame 420 can be connected into an integrated structure through a connecting plate, so that the strength of the fixing frame 400 can be improved, thereby improving the supporting strength of the button circuit board 300.

[0034] In addition, the distance between the side of the first frame 410 away from the notch of the first button mounting groove 111 and the notch of the first button mounting groove 111 can be smaller than the distance between the side of the second frame 420 away from the notch of the second button mounting groove 112 and the notch of the second button mounting groove 112. In this way, the first frame 410 can be prevented from interfering with the battery, and a larger installation space can be provided for the battery.

[0035] Of course, the distance between one side of the first frame 410 away from the slot of the first button mounting slot 111 and the slot of the first button mounting slot 111 may also be greater than or equal to the distance between one side of the second frame 420 away from the slot of the second button mounting slot 112 and the slot of the second button mounting slot 112.

[0036] Optionally, the fixing frame 400 may be made of a hard material to facilitate better assembly. Here, the fixing frame 400 may be made of a polycarbonate (PC) material. Of course, the fixing frame 400 may also be made of other hard materials.

[0037] In an optional embodiment, the electronic device may further include a first reinforcement plate 510, which may be disposed in the housing 600 and connected to the housing 600, and may be located on a side of the first circuit board 310 away from the first button 201, and the first reinforcement plate 510 may be attached to the first circuit board 310.

In this way, the second reinforcement plate 520 may further support and fix the second circuit board 320, thereby improving the stability of the fixation of the second circuit board 320.

[0039] The distance between the first reinforcing plate 510 and the notch of the first button installation slot 111 may be smaller than the distance between the second reinforcing plate 520 and the notch of the second button installation slot 112. In this way, the first reinforcing plate 510 can be prevented from interfering with the battery, and a larger installation space can be provided for the battery.

[0040] Of course, the distance between the first reinforcement plate 510 and the notch of the first button installation slot 111 may also be greater than or equal to the distance between the second reinforcement plate 520 and the notch of the second button installation slot 112 .

[0041] Optionally, when the first reinforcement plate 510 and the second reinforcement plate 520 are close to the antenna component of the electronic device, the first reinforcement plate 510 and the second reinforcement plate 520 can be made of glass fiber epoxy resin material (FR4) to prevent the key circuit board 300 from causing electromagnetic interference to the antenna component. Here, the thickness of the first reinforcement plate 510 and the second reinforcement plate 520 can be at least 0.25 mm. Of course, the first reinforcement plate 510 and the second reinforcement plate 520 can also be made of other materials that can isolate electromagnetic interference. When the first reinforcing plate 510 and the second reinforcing plate 520 are far away 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 plates. In this way, the strength of the first reinforcing plate 510 and the second reinforcing plate 520 can be ensured, and the thickness of the first reinforcing plate 510 and the second reinforcing plate 520 can be made thinner, thereby further increasing the installation space of the battery. Here, the thickness of the first reinforcing plate 510 and the second reinforcing plate 520 can be as small as 0.15 mm. 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 to make the first reinforcing plate 510 and the second reinforcing plate 520 can be determined and selected based on whether it affects the performance of the antenna component.

[0046] Here, the fixing frame 400 is provided with an avoidance opening 401 opposite to the trigger member 350, so that the second end of the striking column 220 can directly contact the trigger member 350. Compared with the contact with the trigger member 350 through the elastic part on the fixing frame 400, the elastic part is reduced to further reduce the space occupied by the button 200, the circuit board and the fixing frame 400, so as to provide a larger installation space for the battery, which is conducive to increasing the volume of the battery.

[0049] Here, the waterproof column 222 can be sealed with the shell 600, so that external moisture or dust can be prevented from entering the shell 600 through the gap between the waterproof column 222 and the shell 600.

[0050] Of course, the striking column 220 may also only include the waterproof column 222 . Specifically, the first end of the waterproof column 222 is connected to the elastic connecting part 212 , and the second end of the waterproof column 222 passes through the shell 600 and the avoidance opening 401 and can contact the trigger member 350 .
