DETAILED DESCRIPTION

[0008] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described below in connection with specific embodiments of the present application and corresponding drawings.

[0010] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connecting" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0011] Please refer to Figures 1 to 11 The embodiments of the present application disclose an electronic device, and the disclosed electronic device comprises a shell 100 and a key 200.

[0012] The shell 100 is a basic component of the electronic device, and is configured to provide a mounting position for other components of the electronic device, wherein the key 200 is arranged on the shell 100. In addition, the shell 100 is also configured to form or assist in forming some functional spaces or structures, such as the mounting hole 110, the inner cavity 120, the third buffer structure 131, the mounting groove 140, and the buffer space 141, which will be described below.

[0013] The key 200 is a core component of the electronic device for realizing a key function (such as a screen locking function, a volume adjustment function, etc.). The shell 100 has the mounting hole 110, and the key 200 includes the pressing structure 210 and the transmission rod 220. The pressing structure 210 is movably arranged on the shell 100, so that the pressing structure 210 can be moved relative to the shell 100 by pressing the pressing structure 210. The transmission rod 220 is movably arranged in the mounting hole 110 and is in transmission connection with the pressing structure 210, so that the pressing structure 210 can drive the transmission rod 220 to slide along the mounting hole 110. Specifically, the pressing structure 210 is configured to drive the transmission rod 220 to slide along the mounting hole 110 when the pressing structure 210 is pressed, so as to cooperate with the flexible circuit board 320 described below through the transmission rod 220, thereby realizing the key function.

[0014] The pressing structure 210 has the first buffer structure 211, which is opposite to the transmission rod 220 to buffer the transmission rod 220. Specifically, the first buffer structure 211 can be a buffer groove, or can be a buffer closed space, and the specific type of the first buffer structure 211 is not limited in the embodiments of the present application.

[0015] Optionally, the pressing structure 210 and the transmission rod 220 can be in transmission connection through abutting, so that the pressing structure 210 can push the transmission rod 220 to slide along the mounting hole 110 by abutting the transmission rod 220, so that the pressing structure 210 can drive the transmission rod 220 to slide along the mounting hole 110. This structure does not need intermediate components to connect, and is beneficial to simplify the structure. It should be noted that the specific transmission connection manner between the pressing structure 210 and the transmission rod 220 is not limited in the embodiments of the present application. For example, in other embodiments, a transmission component can be arranged between the pressing structure 210 and the transmission rod 220, and in this case, the pressing structure 210 and the transmission rod 220 do not contact.

[0016] The electronic device disclosed by the embodiments of the present application improves the structure of the electronic device related to the prior art, sets the pressing structure 210 as a structure with the first buffer structure 211, and sets the first buffer structure 211 opposite to the transmission rod 220, so that in the case that the pressing structure 210 drives the transmission rod 220 to slide along the mounting hole 110 by being pressed, the first buffer structure 211 can be used for buffering, thereby buffering the transmission rod 220. This makes it possible to buffer the pressing structure 210 by the first buffer structure 211 in the case that the electronic device is impacted, falls, or the like, and the impact of the pressing structure 210 is buffered, the impact of the pressing structure 210 transmitted to the transmission rod 220 is reduced, the impact on the transmission rod 220 is reduced, the transmission rod 220 is buffered, and the impact of the transmission rod 220 on the related electronic components in the electronic device is reduced, thereby reducing the risk of failure of the key 200.

[0017] In a further technical solution, the electronic device can further include a circuit board assembly 300, and the electronic device can have an inner cavity 120, which can be in communication with the mounting hole 110. The circuit board assembly 300 can be arranged in the inner cavity 120 and can be opposite to the transmission rod 220. The pressing structure 210 can be arranged on the side of the mounting hole 110 away from the inner cavity 120, and the pressing structure 210 is used to drive the transmission rod 220 to slide along the mounting hole 110 towards the circuit board assembly 300 in the case that the pressing structure 210 is pressed, so that the transmission rod 220 can contact the circuit board assembly 300.

[0018] That is, the circuit board assembly 300 can be arranged on the side of the mounting hole 110 facing the inner cavity 120 and can be opposite to the transmission rod 220. The transmission rod 220 can extend into the inner cavity 120 through the mounting hole 110, and the transmission rod 220 is located between the pressing structure 210 and the circuit board assembly 300. This makes it possible to drive the transmission rod 220 to slide along the mounting hole 110 towards the circuit board assembly 300 by pressing the pressing structure 210, so that the transmission rod 220 can be close to the circuit board assembly 300 and contact the circuit board assembly 300, thereby realizing the key function. It should be noted that the mechanism and cooperation mode of the transmission rod 220 contacting the circuit board assembly 300 to realize the key function are known technologies, which will not be described here.

[0019] Meanwhile, the circuit board assembly 300 can have a second buffering structure 310, which can be opposite to the transmission rod 220 to buffer the transmission rod 220, so that when the electronic device is impacted, dropped or the like to impact the pressing structure 210, the pressing structure 210 drives the transmission rod 220 to impact the circuit board assembly 300, the second buffering structure 310 can be used for buffering to further buffer the transmission rod 220, thereby facilitating to further reduce the impact of the transmission rod 220 on the related electronic components (such as the circuit board assembly 300, etc.) in the inner cavity 120, and further facilitate to further reduce the risk of failure of the key 200. Specifically, the second buffering structure 310 can be a buffering groove or a buffering hole, and the specific type of the second buffering structure 310 is not limited in the embodiments of the present application.

[0020] Optionally, the electronic device can further include a screen 500, and the shell 100 and the screen 500 can jointly form the inner cavity 120. In addition, when the electronic device can further include a cover 700, and the shell 100 can include the first frame 150 and the second frame 160 described below, the first frame 150, the second frame 160, the cover 700 and the screen 500 can jointly form the inner cavity 120. Of course, the specific forming mode of the inner cavity 120 is not limited in the embodiments of the present application, and the types of electronic devices are different, and the forming modes of the inner cavity 120 are different.

[0021] In one embodiment, the circuit board assembly 300 can include a flexible circuit board 320 and a reinforcing plate 330 connected to each other, thereby facilitating to flexibly arrange the circuit board assembly 300 in the inner cavity 120. The flexible circuit board 320 can be arranged on the side of the reinforcing plate 330 facing the transmission rod 220, and the second buffering structure 310 can be arranged on the reinforcing plate 330, so as to avoid arranging the second buffering structure 310 on the flexible circuit board 320, thereby being able to avoid affecting the overall mechanical strength of the flexible circuit board 320 as much as possible, and further facilitating to improve the reliability of the flexible circuit board 320. Specifically, the flexible circuit board 320 can be electrically connected to the main board or the auxiliary board of the electronic device, so that when the pressing structure 210 is pressed, the electrical signal can be transmitted to the main board or the auxiliary board through the flexible circuit board 320, thereby realizing the input of instructions and further realizing the key function. In addition, the material of the reinforcing plate 330 can be metal or alloy, and the main board or the auxiliary board can be a printed circuit board or a flexible printed circuit board, and the embodiments of the present application do not limit this.

[0022] In an alternative technical solution, the circuit board assembly 300 can further include an elastic electrical connecting piece 340, which can be arranged on the side of the flexible circuit board 320 facing the transmission rod 220. Specifically, the elastic electrical connecting piece 340 can be fixed to the flexible circuit board 320 by means of the glue 600, and the embodiments of the present application do not limit the specific connection mode between the elastic electrical connecting piece 340 and the flexible circuit board 320.

[0023] In the specific working process, when the pressing structure 210 is pressed to drive the transmission rod 220 to slide along the mounting hole 110 towards the circuit board assembly 300, the transmission rod 220 can elastically abut against the elastic electrical connecting piece 340, and the elastic electrical connecting piece 340 can be electrically connected with the flexible circuit board 320, so as to realize the input of the instruction and further realize the key function. At this time, the elastic electrical connecting piece 340 can be elastically deformed, and is used to drive the transmission rod 220 to drive the pressing structure 210 to reset, i.e., the elastic electrical connecting piece 340 is used to drive the transmission rod 220 to drive the pressing structure 210 to reset by means of elastic deformation recovery, so as to realize the automatic reset of the transmission rod 220 and the pressing structure 210, and further facilitate the user operation. Specifically, the elastic electrical connecting piece 340 can be a spring, or can be an electrical connecting arm, and the embodiments of the present application do not limit the specific type of the elastic electrical connecting piece 340.

[0024] It should be noted that after the elastic electrical connecting piece 340 drives the transmission rod 220 to drive the pressing structure 210 to reset by means of elastic deformation, the elastic electrical connecting piece 340 can return to the natural state (i.e., the state without deformation caused by external force), at this time, the elastic electrical connecting piece 340 can no longer be electrically connected with the flexible circuit board 320.

[0025] In addition, when the key 200 drives the transmission rod 220 to slide along the mounting hole 110 by means of the pressing structure 210, so as to switch the key 200 between the first position and the second position described below, when the key 200 is in the second position, the transmission rod 220 can elastically abut against the elastic electrical connecting piece 340, and the elastic electrical connecting piece 340 can be electrically connected with the flexible circuit board 320, and at the same time, the elastic electrical connecting piece 340 can be elastically deformed, and the elastic electrical connecting piece 340 is used to drive the transmission rod 220 to drive the pressing structure 210 to reset by means of elastic deformation recovery, so as to enable the key 200 to reset to the first position, and of course, when the key 200 is in the first position, the elastic electrical connecting piece 340 can no longer be electrically connected with the flexible circuit board 320.

[0026] Furthermore, the housing 100 may include a mounting portion 130, which may be disposed within the inner cavity 120. The circuit board assembly 300 may be disposed within the mounting portion 130. The mounting portion 130 may have a third buffer structure 131, which may be opposite to the transmission rod 220 to buffer the transmission rod 220. This structure allows for buffering of the circuit board assembly 300 in the event of an impact, drop, or other event that causes the pressing structure 210 to impact the pressing structure 210, thereby driving the transmission rod 220 to impact the circuit board assembly 300, and subsequently the circuit board assembly 300 to impact the mounting portion 130. This buffering effect is achieved through the third buffer structure 131, thus more effectively buffering the transmission rod 220. This reduces the impact on the circuit board assembly 300 and more effectively reduces the impact of the transmission rod 220 on other related electronic components in the inner cavity 120, thereby further reducing the risk of button 200 failure. Specifically, the third buffer structure 131 can be a buffer groove or a buffer hole. The specific type of the third buffer structure 131 is not limited in the embodiments of this application.

[0027] In this embodiment of the application, the pressing structure 210 may include a first limiting protrusion 212. The first limiting protrusion 212 may be provided on the side of the pressing structure 210 facing the transmission rod 220. The button 200 can drive the transmission rod 220 to slide along the mounting hole 110 through the pressing structure 210, so that the button 200 can switch between a first position and a second position.

[0028] In actual operation, when button 200 is in the first position, the pressing structure 210 can be moved away from the mounting hole 110 and exposed outside the housing 100, so that the user can press button 200 again. The first limiting protrusion 212 can be separated from the end face of the mounting hole 110 facing outside the housing 100, thereby avoiding obstruction when pressing button 200.

[0029] When button 200 is in the second position, the pressing structure 210 is pressed and can approach the mounting hole 110, thereby driving the transmission rod 220 to slide along the mounting hole 110, so that the transmission rod 220 slides into the electronic device. At this time, the first limiting protrusion 212 can abut against the end face of the mounting hole 110 facing away from the housing 100, preventing the pressing structure 210 from moving further towards the mounting hole 110, and thus preventing the pressing structure 210 from driving the transmission rod 220 to slide further into the electronic device along the mounting hole 110, which could easily cause the transmission rod 220 to impact the relevant electronic components inside the electronic device, thereby helping to reduce the risk of button 200 failure.

[0030] Furthermore, there can be multiple first limiting protrusions 212, which can be spaced apart and evenly distributed around the central axis of the transmission rod 220. This allows the pressing structure 210 to more stably abut against the end face of the mounting hole 110 facing away from the housing 100 through the multiple first limiting protrusions 212, thereby minimizing stress concentration. Of course, the first limiting protrusion 212 can also be an annular protrusion extending around the central axis of the transmission rod 220, which helps to increase the contact area between the first limiting protrusion 212 and the end face of the mounting hole 110 facing away from the housing 100, so that the pressing structure 210 can stably abut against the end face of the mounting hole 110 facing away from the housing 100 through the first limiting protrusions 212.

[0031] In one embodiment, the pressing structure 210 may further include a pressing body 213, a first connecting member 214, and a second connecting member 215, which are sequentially fixedly connected. The second connecting member 215 can be connected to the transmission rod 220. The first buffer structure 211 can be located on the side of the pressing body 213 facing the first connecting member 214, and the first limiting protrusion 212 can be located on the side of the second connecting member 215 facing away from the first connecting member 214, thus avoiding the transmission rod 220. This structure is relatively simple and easy to manufacture. In addition, for ease of installation, the first limiting protrusion 212 and the second connecting member 215 can be an integral structure.

[0032] In the specific working process, the side of the pressing body 213 away from the first connector 214 can be exposed outside the housing 100, so that the user can press the side of the pressing body 213 away from the first connector 214 to drive the first connector 214 and the second connector 215 to move synchronously with the pressing body 213, so that the second connector 215 can drive the transmission rod 220 to slide along the mounting hole 110.

[0033] Specifically, the pressing body 213 can be made of metal or alloy, the first connector 214 can be made of PC (polycarbonate), and the second connector 215 can be made of TPU (thermoplastic polyurethane). The pressing body 213, the first connector 214, and the second connector 215 can be sequentially fixed together by adhesive bonding. Alternatively, the pressing body 213 and the first connector 214 can also be fixed together by injection molding, and the first connector 214 and the second connector 215 can be fixed together by adhesive bonding. This application embodiment does not limit these aspects.

[0034] In an optional technical solution, the housing 100 may be provided with a mounting groove 140, and a mounting hole 110 may be provided on the bottom wall of the mounting groove 140 and may communicate with the mounting groove 140. The pressing structure 210 is slidably provided in the mounting groove 140, so that the pressing structure 210 can be driven to slide along the depth direction of the mounting groove 140 by pressing the pressing structure 210. The pressing structure 210 can drive the transmission rod 220 to slide along the mounting hole 110 by sliding along the mounting groove 140, so that the button 200 switches between a first position and a second position.

[0035] In the specific operation, when the button 200 is in the first position, the pressing structure 210 can be moved away from the mounting hole 110 and exposed outside the housing 100 through the mounting groove 140. The pressing structure 210 can be spaced apart from the bottom wall of the mounting groove 140. When the button 200 is in the second position, the pressing structure 210 is pressed and can move closer to the mounting hole 110. The pressing structure 210 and the mounting groove 140 can form a buffer space 141. In this case, the existence of the buffer space 141 ensures that part of the pressing structure 210 does not contact the bottom wall of the mounting groove 140. This structure allows the impact on the pressing structure 210 to diffuse on the pressing structure 210 in the event of a collision or drop. This allows the area of ​​the pressing structure 210 opposite to the buffer space 141 to be cushioned by the buffer space 141, thus better buffering the pressing structure 210. This reduces the impact transmitted from the pressing structure 210 to the transmission rod 220, thereby reducing the impact on the transmission rod 220 and its impact on related electronic components within the electronic device, ultimately reducing the risk of button 200 failure. This structure can be achieved by further deepening the mounting groove 140, ensuring that a portion of the button 200 never contacts the bottom wall of the mounting groove 140 within its travel range.

[0036] Furthermore, when the pressing structure 210 may include a first limiting protrusion 212 and the button 200 is in the second position, the end face of the mounting hole 110 facing the outside of the housing 100 may be distributed on the bottom wall of the mounting groove 140. In this case, the first limiting protrusion 212 may abut against the bottom wall of the mounting groove 140, and the part of the pressing structure 210 other than the first limiting protrusion 212 may still not contact the bottom wall of the mounting groove 140, so that part of the structure of the button 200 will never contact the bottom wall of the mounting groove 140 within its travel range.

[0037] Furthermore, the pressing structure 210 may include a limiting portion 216, and the housing 100 may also include a second limiting protrusion 180. The second limiting protrusion 180 may be disposed at the opening of the mounting groove 140 and protrude towards the mounting groove 140. In specific operation, when the button 200 is in the first position, the limiting portion 216 abuts against the second limiting protrusion 180 in a direction away from the mounting hole 110, thereby preventing the pressing structure 210 from sliding further along the mounting groove 140 in a direction away from the mounting hole 110, so as to minimize the risk of the pressing structure 210 falling out of the mounting groove 140. Of course, in this case, the limiting portion 216 may be spaced apart from the bottom wall of the mounting groove 140. When the button 200 is in the second position, the limiting portion 216 may be spaced apart from the bottom wall of the mounting groove 140 so that the pressing structure 210 and the mounting groove 140 form a buffer space 141.

[0038] Optionally, there can be multiple limiting portions 216, so that the pressing structure 210 can more stably abut against the second limiting protrusion 180 in a direction away from the mounting hole 110 through multiple limiting portions 216, wherein the second limiting protrusion 180 can be provided around the opening of the mounting groove 140. In addition, when the pressing structure 210 includes a second connector 215, a portion of the structure of the second connector 215 can form a limiting portion 216 to avoid providing an additional limiting portion 216, thereby making fuller use of the second connector 215.

[0039] In one feasible technical solution, the electronic device further includes a screen 500 and a cover 700. The housing 100 may include a first frame 150, a second frame 160, and a support member 170. The second frame 160 may be disposed within the first frame 150, and the support member 170 may be disposed within the second frame 160. The screen 500 and the cover 700 may respectively block the opposite ends of the first frame 150 and the opposite ends of the second frame 160, so that the first frame 150, the second frame 160, the screen 500, and the cover 700 can together form an inner cavity 120, and the support member 170 may be disposed within the inner cavity 120. This structure helps to reduce the manufacturing difficulty of the housing 100. In this case, the housing 100 can be a middle frame, the mounting hole 110 can be provided on the second frame 160, the first frame 150 and the second frame 160 can form a mounting groove 140, and a part of the structure of the first frame 150 or a part of the structure of the second frame 160 can form a limiting part 216.

[0040] Specifically, the second frame 160 can be connected to the first frame 150 and the support member 170 by snap-fit ​​or adhesive bonding, respectively. The screen 500 and the cover 700 can be connected to the first frame 150 and the second frame 160 by snap-fit ​​or adhesive bonding, respectively. This embodiment of the application does not limit this. Of course, in other embodiments, the electronic device may also include the screen 500, and the housing 100 may include the first frame 150, the second frame 160, the support member 170, and the cover 700.

[0041] Furthermore, when the housing 100 includes the mounting portion 130, a portion of the structure of the support member 170 can form the mounting portion 130, thereby avoiding the need to additionally provide the mounting portion 130. This allows for more full utilization of the support member 170, which in turn helps to improve the compactness of the electronic device structure.

[0042] In the embodiments disclosed in this application, there can be multiple buttons 200 and multiple mounting holes 110. These mounting holes 110 can be uniformly disposed on the bottom wall of the mounting groove 140 and can all communicate with the mounting groove 140. Each mounting hole 110 corresponds one-to-one with a multiple transmission rod 220. Multiple pressing structures 210 can be connected sequentially and can all be movably disposed within the mounting groove 140. When at least one button 200 is in the second position, the multiple pressing structures 210 can all form a buffer space 141 with the mounting groove 140. This structure allows for buffering of the pressing structure 210 in the event of an impact, drop, or other event that affects it. This buffer space 141 provides cushioning, reducing the impact transmitted from the pressing structure 210 to the transmission rod 220, thereby reducing the impact on the transmission rod 220 and consequently reducing the impact on related electronic components within the electronic device. This, in turn, helps to reduce the risk of button 200 failure.

[0043] Of course, the connected parts of adjacent pressing structures 210 can be opposite to the buffer space 141, so that when the electronic device is impacted or dropped and the corresponding pressing structure 210 is impacted, the buffer space 141 can protect the connected parts of adjacent pressing structures 210, thereby minimizing the possibility of the connected parts of adjacent pressing structures 210 impacting the housing 100 and causing damage to the two pressing structures 210, and thus the two buttons 200, which helps to further improve the reliability of the buttons 200.

[0044] Furthermore, when the electronic device includes a circuit board assembly 300, and the circuit board assembly 300 includes a flexible electrical connector 340, there can be multiple flexible electrical connectors 340, and multiple flexible electrical connectors 340 can correspond one-to-one with multiple transmission rods 220, so that when the corresponding pressing structure 210 is pressed and drives the corresponding transmission rod 220 to slide along the corresponding mounting hole 110 toward the circuit board assembly 300, the corresponding transmission rod 220 can elastically abut against the corresponding flexible electrical connector 340, and the corresponding flexible electrical connector 340 can be electrically connected to the flexible circuit board 320.

[0045] Optionally, there can be two buttons 200, and the two button pressing structures 210 can be connected. In this case, the two buttons 200 can be volume buttons, so as to realize the volume increase adjustment function and the volume decrease adjustment function respectively.

[0046] In an optional embodiment, the electronic device may further include a sealing structure 400, which may be disposed between the transmission rod 220 and the mounting hole 110 to achieve a sealed fit between the transmission rod 220 and the mounting hole 110, thereby preventing dust, moisture, etc. from entering the electronic device from between the transmission rod 220 and the mounting hole 110 and affecting the electronic components inside the electronic device. Specifically, the sealing structure 400 may be a sealing ring, which may be sleeved outside the transmission rod 220 and disposed in the mounting hole 110 to achieve a sealed fit between the transmission rod 220 and the mounting hole 110. The specific type of sealing structure 400 is not limited in this embodiment.

[0047] The electronic devices disclosed in this application can be smartphones, tablets, e-book readers, wearable devices (such as smartwatches), video game consoles, etc. This application does not limit the specific types of electronic devices.
