Description

Technical Field

[0001] The embodiments of the present application relate to the field of terminal technology, and in particular to an electronic device. Background Art

[0002] With the explosive growth of electronic devices such as mobile phones or tablet computers, electronic devices have gradually become one of the frequently used devices in people's daily life or work. Electronic devices are usually equipped with physical buttons, such as volume control buttons. The electronic device includes a shell. A mounting hole is provided on the shell. The button is assembled in the mounting hole. The button is connected to the shell. For example, the shell includes a middle frame. The button is connected to the middle frame. The middle frame has a limiting effect on the button, so that the button can be pressed or released normally and will not fall off the middle frame. The user can perform corresponding operations on the electronic device through the button, for example, by pressing the volume control button, the electronic device can turn up or down the volume. At present, the buttons on the electronic device are mainly operated by pressing, which is a traditional mechanical button with a single function. Summary of the invention

[0003] The embodiment of the present application provides an electronic device, which can diversify the operation mode and function of buttons, which is conducive to improving the operation experience of the electronic device.

[0004] The present application provides an electronic device, which includes a housing, a button, a switch assembly, a cantilever assembly and a detection assembly. The button is arranged on the housing. The button includes a keycap and at least two trigger parts. At least two trigger parts are arranged on the same side of the keycap. At least two trigger parts are arranged at intervals. The switch assembly includes a conductive member arranged in a one-to-one correspondence with the trigger part. The conductive member is arranged on the side of the trigger part facing away from the keycap. The cantilever assembly includes a cantilever arranged in a one-to-one correspondence with the trigger part. The cantilever includes a fixed part and a movable end. The fixed part is connected to the housing. The movable end is connected to the trigger part arranged corresponding to the movable end. And, the detection assembly includes a sensor arranged in a one-to-one correspondence with the cantilever. Among them, the keycap is used to drive the trigger part to move to trigger the conductive member. The trigger part is used to drive the movable end to move so that the cantilever undergoes bending deformation. The sensor is used to detect the bending deformation amount of the cantilever.

[0005] In the electronic device of the embodiment of the present application, a button is arranged on the housing. The button corresponds to the switch assembly. When the user's finger is placed at a predetermined position of the keycap and remains motionless, and a large pressing force is applied to the keycap of the key, the keycap can drive the corresponding trigger part to move to trigger the conductive part of the switch assembly, so that the electronic device can realize the pressing operation of the key, for example, single-clicking the key or double-clicking the key. After the user's finger is placed at the predetermined position of the keycap, the keycap can be slid on the keycap. At this time, the pressing force applied by the finger to the keycap of the key is relatively small, so that the corresponding trigger part moves but the conductive part can not be triggered to realize the conduction of the switch assembly. During the sliding process of the user's finger, different trigger parts can respectively apply forces to the corresponding cantilevers. Each sensor of the detection assembly can respectively detect the bending deformation of each cantilever to determine the first position and the second position of the finger. The electronic device can generate sliding operation information based on the information of the first position and the second position, so that the electronic device can respond to the sliding operation information to perform the corresponding function. Therefore, the electronic device can realize the sliding operation through the key. The key in the electronic device of the embodiment of the present application can realize the pressing operation, and can also realize the sliding operation, so that the operation mode and function of the key are diversified, which is conducive to improving the operation experience of the electronic device.

[0006] In a possible implementation manner, there are two triggering parts, which are respectively located on two sides of the center point of the key cap.

[0007] The two trigger parts are arranged at intervals and are respectively located on both sides of the center point of the keycap, which further reduces the possibility of mutual influence between the two trigger parts. When a pressing force is applied to the area on the keycap corresponding to one trigger part, the pressing force is not easily transmitted through the keycap to the other trigger part far away from the pressing position, so that the trigger part far away from the pressing position may not move or move a small amount.

[0008] In a possible implementation, the two trigger portions are symmetrically arranged relative to the center point of the key cap, and the two cantilevers are symmetrically arranged.

[0009] The structures and sizes of the two trigger parts can be the same, which is conducive to ensuring the consistency of the structures and sizes of the two. The structures and sizes of the two cantilevers can be the same, which is conducive to ensuring the consistency of the structures and sizes of the two, and reducing the possibility of adverse effects on the detection results of the detection component due to differences in the structures and sizes of the two.

[0010] In a possible embodiment, the two trigger parts include a first trigger part and a second trigger part. Along the arrangement direction of the two trigger parts, the fixed part of one cantilever is located at an end of the first trigger part away from the second trigger part, and the fixed part of the other cantilever is located at an end of the second trigger part away from the first trigger part.

[0011] In a possible implementation, along the arrangement direction of the two trigger parts, the minimum distance between the first trigger part and the second trigger part is K0, the minimum distance between the first trigger part and the end edge of the keycap close to the first trigger part is K1, and the minimum distance between the second trigger part and the end edge of the keycap close to the second trigger part is K2. Wherein, K1 and K2 are both smaller than K0.

[0012] In the key of this embodiment, the minimum distance between the two triggering parts is relatively large, so the size of the portion of the keycap located between the two triggering parts is relatively large. Therefore, when a pressing force is applied to the area above one triggering part of the keycap, the area above the other triggering part of the keycap is not likely to be deformed synchronously, so that the keycap is not likely to cause the triggering part away from the pressing position to move.

[0013] In a possible implementation manner, one trigger portion is disposed at an end of the key cap, and the other trigger portion is disposed at the other end of the key cap.

[0014] In a possible implementation, the sensor is disposed between the movable end and the fixed portion of the cantilever.

[0015] When the trigger part drives the movable end to move, the suspended part of the cantilever between the fixed part and the trigger part is prone to bending deformation, which is beneficial to improving the detection accuracy of the sensor between the fixed part and the trigger part.

[0016] In a possible implementation, the movable end of at least one cantilever has a through hole, and the triggering part is disposed through the through hole.

[0017] The corresponding trigger part can be inserted into the through hole, so that the cantilever and the trigger part can limit and constrain each other, reducing the possibility of a large error in the bending deformation of the cantilever due to a large deviation in the relative position of the trigger part and the cantilever during the movement of the cantilever driven by the trigger part.

[0018] In a possible embodiment, the fixing portion of at least one cantilever is detachably connected to the shell, which helps to reduce the difficulty of assembly or disassembly between the cantilever and the shell, facilitates the repair or replacement of the cantilever separately, and improves the maintenance convenience of the electronic device.

[0019] In a possible implementation, the cantilever assembly further includes a fastener, and the fixing portion of at least one cantilever is detachably connected to the housing via the fastener.

[0020] The fastener can effectively limit the fixing part, reducing the possibility that the fixing part is loose and shaken, which may cause the relative position between the cantilever and the shell to change easily.

[0021] In a possible implementation, the fixing portion has an assembly hole, and the fastener is passed through the assembly hole.

[0022] In a possible implementation, a sensor is disposed on a side of at least one cantilever facing the key cap.

[0023] In a possible implementation, sensors are respectively arranged on a side of at least one cantilever facing the keycap and a side of the at least one cantilever facing away from the keycap.

[0024] In a possible implementation manner, there is a gap between at least one triggering portion and a conducting member corresponding to the triggering portion.

[0025] When the keycap of the key is not pressed, there is a distance between the trigger part and the conductive part, so that the trigger part and the conductive part do not contact each other. When the user needs to perform a sliding operation through the key, the keycap is pressed. Since there is a distance between the trigger part and the conductive part, the keycap can relatively easily drive the trigger part to move, which is beneficial to improve the sensitivity of the trigger part to drive the movable end to move. When the distance the trigger part moves is less than the distance between the trigger part and the conductive part, the conductive part will not apply a reaction force to the trigger part, so that the trigger part does not need to overcome the reaction force of the conductive part, so that a small pressing force is applied to the keycap, and the cantilever can be driven to bend and deform through the trigger part.

[0026] In a possible implementation manner, a conducting member is disposed on a side of at least one movable end facing away from the key cap.

[0027] In a possible implementation manner, there is a gap between the cantilever and the key cap.

[0028] After the keycap is pressed, the keycap drives the trigger part to move, and at the same time, the keycap moves closer to the cantilever. Since there is a gap between the cantilever and the keycap, it is not easy for the keycap to contact the cantilever. If the keycap contacts the cantilever, the cantilever will be bent by both the trigger part and the keycap. There is a possibility that the bending deformation amount of the cantilever caused by the trigger part alone and the bending deformation amount of the cantilever caused by both the trigger part and the keycap are different, so there is a possibility that the sensor detection result will be wrong or biased, affecting the detection accuracy of the sensor.

[0029] In a possible implementation, bosses are respectively arranged at two ends of the keycap. At least two triggering parts are located between the two bosses. The bosses are arranged facing the cantilever. There is a gap between the cantilever and the bosses.

[0030] In a possible implementation, at least one triggering portion and a cantilever corresponding to the triggering portion are an integrally formed structure.

[0031] The corresponding trigger part and cantilever form an overall structure with high mechanical strength, making it difficult for the trigger part and cantilever to separate. There is no assembly gap between the integrally formed trigger part and cantilever, which improves the movement synchronization of the trigger part and cantilever, so that when the trigger part moves, the trigger part can synchronously drive the cantilever to bend and deform.

[0032] In a possible implementation manner, at least one triggering portion is clamped with a cantilever corresponding to the triggering portion.

[0033] The trigger part and the cantilever are detachably connected by means of a snap connection. The trigger part and the cantilever are directly connected by a snap connection structure without the need for additional connecting parts, which is conducive to reducing the number of parts used and reducing the difficulty of assembly. In addition, one of the trigger part and the cantilever can be repaired or replaced separately, which is conducive to reducing the difficulty and cost of repair.

[0034] In a possible implementation manner, at least one cantilever is a sheet-like structure.

[0035] Along the thickness direction of the cantilever, the trigger part is located on one side of the keycap. When the cantilever with a sheet structure is subjected to the force of the trigger part, the cantilever is prone to bending deformation, and when subjected to the force along its own thickness direction, it is easy to produce a relatively large bending deformation, which is conducive to the sensor accurately detecting the bending deformation amount of the cantilever and improving the detection precision and accuracy.

[0036] In a possible implementation, at least one sensor includes a strain gauge, so that the sensor itself has a high detection sensitivity, which is conducive to ensuring the precision and accuracy of the detection result.

[0037] In a possible implementation, the electronic device further includes a linear motor and a controller, and the sensor and the linear motor are respectively connected to the controller for communication.

[0038] Every time the user's finger slides a predetermined distance on the keycap, different sensors send detection signals to the controller, and the controller simultaneously controls the linear motor to turn on to provide vibration tactile feedback to the user, allowing the user to judge the current sliding distance of the finger and improve the user experience of the electronic device.

[0039] In a possible implementation, the housing includes a middle frame, the button is arranged in the middle frame, and the fixing portion is connected to the middle frame.

[0040] In a possible embodiment, the middle frame is provided with a receiving groove. The bottom wall of the receiving groove is provided with guide holes corresponding to at least two triggering parts one by one. The guide holes are connected to the receiving groove. At least part of the keycap is located in the receiving groove. The triggering part is passed through the guide hole corresponding to the triggering part. The guide hole is opposite to the conductive part. The bottom wall of the receiving groove is located between the keycap and the cantilever.

[0041] The middle frame can form a limit constraint on the button, which is helpful to reduce the possibility of position deviation of the trigger part.

[0042] In a possible embodiment, the middle frame includes a receiving portion. Along the length direction of the keycap, two ends of the receiving portion are respectively provided with avoidance cavities. The avoidance cavity is connected to the receiving portion. At least part of the keycap is located in the receiving portion. The key further includes hanging platforms arranged at two ends of the keycap in the length direction. The hanging platforms are located in the avoidance cavity.

[0043] In a possible implementation manner, the fixing portion is disposed on the inner side of the middle frame.

[0044] A second aspect of the present application provides a key device, which includes a key, a cantilever assembly and a detection assembly.

[0045] The key includes a keycap and at least two triggering parts. The triggering part is arranged on the same side of the keycap. At least two triggering parts are arranged on the same side of the keycap. At least two triggering parts are arranged at intervals. The cantilever assembly includes a cantilever arranged in a one-to-one correspondence with the triggering part. The cantilever includes a fixed part and a movable end. The movable end is connected to the triggering part. The detection assembly includes a sensor arranged in a one-to-one correspondence with the cantilever. The triggering part is used to drive the movable end to move so that the cantilever is bent and deformed. The sensor is used to detect the bending deformation of the cantilever.

In the embodiment of the present application, the form of the terminal device is not specifically limited.

[0081] In the embodiment of the present application, Figure 1 The structure of the electronic device 10 is schematically shown. Figure 1 As shown, the electronic device 10 is taken as an example of a handheld device with a wireless communication function. The handheld device with a wireless communication function may be, for example, a mobile phone.

[0082] Figure 2A partial exploded structure of the electronic device 10 is schematically shown. Figure 3 The partial cross-sectional structure of the electronic device 10 is schematically shown. Figure 2 and Figure 3 As shown, the electronic device 10 of the embodiment of the present application includes a display assembly 20 , a housing 30 , a mainboard 40 and an electronic device 50 .

[0083] The display assembly 20 has a display area for displaying image information. The display assembly 20 is mounted on the housing 30, and the display area of ​​the display assembly 20 is exposed to the outside so as to present image information to the user. The main board 40 is connected to the housing 30 and is located inside the display assembly 20, so that the user cannot easily observe the main board 40 from the outside of the electronic device 10.

[0084] The electronic device 50 is disposed on the mainboard 40. The mainboard 40 may be a printed circuit board (PCB). The electronic device 50 is soldered to the mainboard 40 by a soldering process. The electronic device 50 includes but is not limited to a central processing unit (CPU), an intelligent algorithm chip or a power management IC (PMIC).

[0085] Devices such as the main board 40 or the battery 60 may be arranged in the housing 30. Exemplarily, the housing 30 may include a middle frame 31 and a back cover 32. The display assembly 20 and the back cover 32 are respectively connected to the middle frame 31. The middle frame 31 has a storage space 31a. Devices such as the main board 40 or the battery 60 may be arranged in the storage space 31a. The material of the middle frame 31 may include but is not limited to aluminum alloy or plastic. The middle frame 31 may include a left side frame, a top frame, a right side frame and a bottom frame. The left side frame, the top frame, the right side frame and the bottom frame are sequentially connected to form a ring-shaped middle frame 31. The middle frame 31 has an outer wall and an inner wall arranged in opposite directions. The outer wall of the middle frame 31 refers to the surface facing away from the storage space 31a. When the electronic device 10 is observed from the outside, the outer wall of the middle frame 31 is in a visible state. The inner wall of the middle frame 31 refers to the surface facing the storage space 31a. When the electronic device 10 is observed from the outside, the inner wall of the middle frame 31 is in an invisible state.

[0086] Figure 4 Schematic showing the partial structure of the switch assembly. Figure 4As shown, the electronic device 10 further includes a switch assembly 70. The switch assembly 70 may include a conductive member 71. The conductive member 71 is used to realize the conduction or disconnection of the switch assembly 70. For example, the conduction member 71 is triggered to realize the conduction of the switch assembly 70. The conduction member 71 is released to realize the disconnection of the switch assembly 70. Exemplarily, the switch assembly 70 may further include a circuit board 72. The conductive member 71 may be disposed on the circuit board 72. When the conductive member 71 is triggered, the conductive member 71 may contact and conduct with the circuit board 72 to realize the conduction of the switch assembly 70.

[0087] Figure 5 The partial structure of the electronic device 10 is schematically shown. Figure 5 As shown, the electronic device 10 further includes a key device. The key device is arranged on the housing 30. Exemplarily, the housing 30 includes a middle frame 31. The key device is arranged on the middle frame 31. The key device includes a key 80. The key 80 is arranged on the housing 30. Exemplarily, the housing 30 includes a middle frame 31. The key 80 is arranged on the middle frame 31. For example, the key 80 can be arranged on the left frame or the right frame of the middle frame 31, so that the user can operate the key 80 with one hand, such as the user can operate the key 80 with a thumb. When the key 80 is pressed, the key 80 can trigger the conductive member 71 to realize the corresponding function of the electronic device 10. Exemplarily, the conductive member 71 can be an elastic body. When the key 80 is pressed, the key 80 moves toward the inside of the electronic device 10. After the key 80 contacts the conductive member 71, a force can be applied to the conductive member 71 to cause the conductive member 71 to undergo elastic deformation. When the force on the key 80 disappears, the key 80 can move toward the outside of the electronic device 10 and return to the initial position, so as to facilitate pressing again. Under the action of the elastic restoring force of the conductive member 71 itself, the conductive member 71 can be restored to the initial position, which is convenient for pressing again. Exemplarily, the conductive member 71 can be, but is not limited to, a metal spring. For example, the metal spring can be a metal dome switch. Exemplarily, the switch assembly 70 can also include a circuit board 72. The circuit board 72 can be a flexible printed circuit board (FPCB).

[0088] Figure 6 A partial structure of the electronic device 10 is schematically shown. Figure 7 The partial cross-sectional structure of the electronic device 10 is schematically shown. Figure 6 and Figure 7As shown, the key 80 of the embodiment of the present application includes a keycap 81 and at least two triggering parts 82. The keycap 81 has a pressing surface 81a. When the key 80 is applied to the electronic device 10, the pressing surface 81a of the keycap 81 can be exposed to the outside of the electronic device 10, so that the pressing surface 81a can be observed when observed from the outside. The user can apply pressing force to the key 80 through the pressing surface 81a. Exemplarily, a part of the keycap 81 can protrude from the outer surface of the housing 30 to facilitate pressing the key 80. At least two triggering parts 82 are arranged on the same side of the keycap 81. The key 80 is applied to the electronic device 10, and when observed from the outside of the electronic device 10, the triggering part 82 is blocked by the keycap 81, so that the triggering part 82 is not easy to observe. At least two triggering parts 82 are arranged at intervals. There is a spacing between each triggering part 82, and there is no contact between two adjacent triggering parts 82. Exemplarily, the keycap 81 of the key 80 is in the shape of a strip. At least two triggering parts 82 are arranged at intervals along the length direction of the keycap 81. Exemplarily, there may be two triggering portions 82 , and the two triggering portions 82 may be located at two sides of the center point S of the key cap 81 , respectively.

[0089] The switch assembly 70 includes a conductive member 71 that is arranged in a one-to-one correspondence with the trigger portion 82, for example, one conductive member 71 is arranged corresponding to one trigger portion 82. The conductive member 71 is arranged on the side of the trigger portion 82 that is away from the key cap 81. The conductive member 71 is arranged corresponding to each trigger portion 82. The key 80 can realize a pressing operation. After the key cap 81 is pressed, the key cap 81 is used to drive the trigger portion 82 to move, so that the trigger portion 82 can apply a force to the conductive member 71 to trigger the conductive member 71, so that the switch assembly 70 is turned on. The trigger portion 82 is used to trigger the corresponding conductive member 71.

[0090] At least two triggering parts 82 are arranged at intervals, so that each triggering part 82 maintains independent operation. By applying a pressing force to the area corresponding to one triggering part 82 on the keycap 81, the triggering part 82 can move and trigger the corresponding conductive member 71, and the pressing force is not easily transmitted to other triggering parts 82 through the keycap 81, so that other triggering parts 82 may not move or move less, which is conducive to ensuring that other triggering parts 82 do not trigger the corresponding conductive member 71.

[0091] For example, the button 80 can be used to control the volume of the electronic device 10. One of the trigger parts 82 can be used as a volume increase trigger part, and the other trigger part 82 can be used as a volume decrease trigger part, so that pressing the corresponding trigger part 82 can trigger the corresponding conductive member 71, thereby achieving volume increase or decrease.

[0092] In some examples, at least one triggering portion 82 may be a columnar structure, for example, may be cylindrical. Exemplarily, each triggering portion 82 may be a columnar structure.

[0093] In some examples, at least one trigger portion 82 and the keycap 81 may be an integrally formed structure, which is beneficial to improving the connection stability and reliability between the trigger portion 82 and the keycap 81. Exemplarily, among all the trigger portions 82, each trigger portion 82 and the keycap 81 may be an integrally formed structure.

[0094] In some examples, at least one trigger portion 82 and the keycap 81 may be a split structure, that is, the trigger portion 82 and the keycap 81 are two separate structural members. The trigger portion 82 and the keycap 81 may be assembled with each other. Exemplarily, the trigger portion 82 and the keycap 81 are detachably connected, which may facilitate the repair or replacement of the trigger portion 82 or the keycap 81 separately. Exemplarily, among all the trigger portions 82, each trigger portion 82 and the keycap 81 may be a split structure.

[0095] Exemplarily, the middle frame 31 includes a housing portion 311. Along the length direction of the keycap 81, avoidance cavities 313 are respectively provided at both ends of the housing portion 311. The avoidance cavity 313 is connected to the housing portion 311. At least part of the keycap 81 is located in the housing portion 311. The key 80 also includes a hanging platform 83 arranged at two ends of the keycap 81 in the length direction. The hanging platform 83 is located in the avoidance cavity 313. The middle frame 31 can limit the key 80 through the hanging platform 83, so that the key 80 can be pressed or released normally, and is not easy to fall off the middle frame 31. Exemplarily, the length direction of the keycap 81 can be the same as the arrangement direction X of the trigger portion 82.

[0096] For example, after the trigger part 82 moves due to the pressing force on the keycap 81, the hanging platform 83 moves relative to the middle frame 31, so that a gap may appear between the hanging platform 83 and the middle frame 31. After the pressing force on the keycap 81 disappears, the keycap 81 may return to its initial position, and the hanging platform 83 also returns to its initial position.

[0097] See also Figures 6 to 8 As shown, in the electronic device 10 of the embodiment of the present application, the key device also includes a cantilever assembly 90. The cantilever assembly 90 includes a cantilever 91. The number of cantilevers 91 is at least two. The triggering portion 82 is arranged in a one-to-one correspondence with the cantilever 91, for example, a cantilever 91 can be arranged corresponding to a triggering portion 82. Cantilevers 91 are respectively arranged corresponding to each triggering portion 82. The cantilever 91 includes a fixed portion 911 and a movable end 912. The fixed portion 911 of the cantilever 91 is connected to the housing 30 to fix the cantilever 91.

[0098] For example, Figure 8 The partial cross-sectional structure of the electronic device 10 is schematically shown. Figure 8As shown, the housing 30 includes a middle frame 31. The key 80 is arranged in the middle frame 31. The middle frame 31 is provided with a receiving groove 312. The bottom wall 312a of the receiving groove 312 is provided with guide holes 312b corresponding to at least two trigger parts 82, that is, the number of guide holes 312b is the same as the number of trigger parts 82. Each trigger part 82 is provided with a corresponding guide hole 312b. The guide hole 312b is connected to the receiving groove 312. At least part of the keycap 81 is located in the receiving groove 312. The trigger part 82 is penetrated in the guide hole 312b corresponding to the trigger part 82. The guide hole 312b is opposite to the conductive member 71. The bottom wall 312a of the receiving groove 312 is located between the keycap 81 and the cantilever 91. The middle frame 31 can separate the keycap 81 from the cantilever 91. The middle frame 31 can form a limit constraint on the key 80, which is conducive to reducing the possibility of position displacement of the trigger part 82.

[0099] Exemplarily, the shell 30 includes a middle frame 31. The fixing portion 911 is connected to the middle frame 31. For example, the fixing portion 911 can be arranged on the inner side of the middle frame 31. The inner side of the middle frame 31 refers to the side of the middle frame 31 facing the accommodating space 31a. The movable end 912 of the cantilever 91 is connected to the trigger portion 82 arranged corresponding to the movable end 912. The trigger portion 82 drives the corresponding movable end 912 to move so that the corresponding cantilever 91 is bent and deformed. The area on the keycap 81 corresponding to the trigger portion 82 is subjected to pressing force, so that when the keycap 81 drives the trigger portion 82 to move, the trigger portion 82 can synchronously drive the movable end 912 of the corresponding cantilever 91 to move, so that the suspended part of the corresponding cantilever 91 is bent and deformed.

[0100] When the conductive member 71 needs to be triggered by the trigger part 82, the user's fingers are required to apply a relatively large pressing force to the keycap 81, thereby performing a significant pressing operation on the keycap 81, so that the corresponding trigger part 82 moves a large amount to meet the displacement requirement of the trigger conductive member 71. Fig. 9 The process of finger 200 sliding on key cap 81 is schematically shown. Fig. 9 As shown in (a) to (c), exemplarily, when the user's finger 200 slides on the keycap 81, the user's finger 200 applies a pressing force to the keycap 81, but the pressing force is relatively small at this time, so that the movement of the trigger part 82 is small, which does not meet the displacement requirement of the triggering conductive member 71, so that although the trigger part 82 moves, it does not trigger the conductive member 71 to realize the conduction of the switch assembly 70. When the user's finger 200 slides on the keycap 81, when the user's finger 200 is located at different positions on the keycap 81, the displacement of each trigger part 82 is different, so that the bending deformation of each cantilever 91 is also different.

[0101] For example, the key 80 includes two trigger parts 82 and two cantilevers 91. Fig. 9 The positions shown are for reference, the triggering part 82 on the left can be used as the first triggering part, and the triggering part 82 on the right can be used as the second triggering part. The sensor on the left can be used as the first sensor, and the sensor on the right can be used as the second sensor. The cantilever 91 on the left can be used as the first cantilever, and the cantilever 91 on the right can be used as the second cantilever.

[0102] See also Fig. 9 As shown in (a), the closer the finger 200 is to the first trigger part, the larger the displacement of the first trigger part is, while the smaller the displacement of the second trigger part is, so the bending deformation of the first cantilever is relatively larger, while the bending deformation of the second cantilever is relatively smaller. Fig. 9 As shown in (c), the closer the position of the finger 200 is to the second trigger part, the larger the displacement of the second trigger part is, and the smaller the displacement of the first trigger part is, so that the bending deformation of the second cantilever is relatively larger, and the bending deformation of the first cantilever is relatively smaller.

[0103] Exemplarily, the cantilever 91 is elastic. When the pressing force on the key cap 81 disappears, the cantilever 91 can move to the initial position under the action of its own elastic restoring force, so as to facilitate pressing again.

[0104] Exemplarily, at least two cantilevers 91 are arranged at intervals. For example, along the arrangement direction X of the triggering portion 82, at least two cantilevers 91 are arranged at intervals. Two adjacent cantilevers 91 do not overlap or contact each other, which helps to reduce the possibility of position interference between the two adjacent cantilevers 91 when one of the two adjacent cantilevers 91 is bent and deformed.

[0105] Exemplarily, the material of at least one cantilever 91 may be, but is not limited to, a metal material, for example, the material of the cantilever 91 may be stainless steel, copper, or a copper alloy. Exemplarily, among all the cantilevers 91, the material of each cantilever 91 may be a metal material.

[0106] See also Figure 6 As shown, in the electronic device 10 of the embodiment of the present application, the key device further includes a detection component 100. The detection component 100 includes a sensor 101. The sensor 101 is respectively set corresponding to each cantilever 91. Exemplarily, the cantilever 91 and the sensor 101 are set in a one-to-one correspondence. The sensor 101 is used to detect the bending deformation of the cantilever 91. The sensor 101 is used to detect the current bending deformation of the cantilever 91, and the sensor 101 can output a corresponding detection signal.

[0107] In some examples, the key 80 includes two triggering parts 82 and two cantilevers 91. Fig. 9The positions shown are for reference, the triggering part 82 on the left can be used as the first triggering part, and the triggering part 82 on the right can be used as the second triggering part. The sensor 101 on the left can be used as the first sensor, and the sensor 101 on the right can be used as the second sensor. The cantilever 91 on the left can be used as the first cantilever, and the cantilever 91 on the right can be used as the second cantilever.

[0108] See also Fig. 9 As shown in (a), the user's finger 200 is placed on the key cap 81 in an area close to the first trigger portion. When the first sensor detects that the first cantilever is bent, the first sensor detects the bending deformation of the first cantilever and outputs a detection signal, while the second sensor detects the bending deformation of the second cantilever and outputs a detection signal. The bending deformation of the first cantilever is greater than the bending deformation of the second cantilever. The current position of the finger 200 is determined to be the first position. Fig. 9 As shown in (a) to (c), when the first sensor detects that the bending deformation of the first cantilever changes from large to small, and the second sensor detects that the bending deformation of the second cantilever changes from small to large, it is determined that the finger 200 is sliding on the key cap 81 and the finger 200 is sliding toward the second triggering portion. Fig. 9 As shown in (c), when the first sensor detects that the bending deformation of the first cantilever no longer changes, and the second sensor detects that the bending deformation of the second cantilever no longer changes, it is determined that the finger 200 stops sliding, and the current position of the finger 200 is the second position. The electronic device 10 can generate sliding operation information based on the information of the first position and the second position.

[0109] The user's finger 200 may also be placed on the keycap 81 in an area near the second trigger portion. When the second sensor detects that the second cantilever is bent and deformed, the second sensor detects the bending deformation of the second cantilever, and the second sensor outputs a detection signal, while the first sensor detects the bending deformation of the first cantilever, and the first sensor outputs a detection signal. The bending deformation of the second cantilever is greater than the bending deformation of the first cantilever. The current position of the finger 200 is determined to be the first position. When the second sensor detects that the bending deformation of the second cantilever changes from large to small, and the first sensor detects that the bending deformation of the first cantilever changes from small to large, it is determined that the finger 200 is sliding on the keycap 81 and the finger 200 is sliding toward the first trigger portion. When the second sensor detects that the bending deformation of the second cantilever no longer changes, and the first sensor detects that the bending deformation of the first cantilever no longer changes, it is determined that the finger 200 stops sliding, and the current position of the finger 200 is the second position. The electronic device 10 can generate sliding operation information based on the information of the first position and the second position.

[0110] For example, the information of the first position and the second position may be a sliding distance from the first position to the second position, or the information of the first position and the second position may be a time difference from sliding from the first position to the second position.

[0111] Exemplarily, the first position can be used as the starting position of the sliding action, and the second position can be used as the ending position of the sliding action. For example, the button device is arranged on the side of the electronic device 10. The first position is close to the top of the electronic device 10, and the second position is close to the bottom of the electronic device 10. When sliding from the first position to the second position, the electronic device 10 generates sliding operation information for sliding downward, for example, functions such as displaying the next page of the document or moving the document content downward can be realized. Alternatively, the first position is close to the bottom of the electronic device 10, and the second position is close to the top of the electronic device 10. When sliding from the first position to the second position, the electronic device 10 generates sliding operation information for sliding upward, for example, functions such as displaying the previous page of the document or moving the document content upward can be realized.

[0112] The electronic device 10 of the embodiment of the present application can determine that the user's finger 200 is sliding on the key cap 81, and can also determine the information of the first position and the second position according to the change in the bending deformation of each cantilever 91. The electronic device 10 can respond to the sliding operation information to perform a corresponding function. For example, the electronic device 10 can adjust the brightness of the display screen according to the sliding operation information, or realize functions such as moving the currently displayed document content up or down.

[0113] In the embodiment of the present application, the trigger parts 82 are arranged at intervals. Therefore, when the finger 200 is placed on the keycap 81 near a trigger part 82, the trigger part 82 can drive the cantilever 91 below to bend and deform. At this time, the pressing force is not easily transmitted through the keycap 81 to the trigger part 82 relatively far away from the finger 200, so that the trigger part 82 far away from the finger 200 is not easy to drive the corresponding cantilever 91 to bend and deform, which can effectively ensure that the bending deformation amount of the cantilever 91 close to the finger 200 is greater than the bending deformation amount of the cantilever 91 far away from the finger 200.

[0114] In addition, the trigger portions 82 are arranged at intervals so that when the finger 200 slides from a position close to one trigger portion 82 toward another trigger portion 82, for example, Fig. 9When the position of the trigger part 82 on the left side slides toward the trigger part 82 on the right side, the change in the bending deformation of each cantilever 91 can be relatively obvious, which is conducive to accurately judging the sliding action of the finger 200 on the keycap 81, and is conducive to accurately judging the current position of the finger 200 when the sliding stops. Therefore, the manner in which the trigger parts 82 are arranged at intervals can effectively identify the sliding action of the finger 200 on the keycap 81, ensure the detection accuracy of the current position of the finger 200, and enable the electronic device 10 to implement the sliding operation through the key 80.

[0115] For example, the finger 200 may slide on the keycap 81 in a manner that is, but not limited to, the finger 200 is placed at a position directly above one trigger portion 82 and slides to a position directly above another trigger portion 82. Fig. 9 The user slides the control panel 100 from a position directly above the trigger portion 82 on the left side of the middle panel to a position directly above the trigger portion 82 on the right side of the middle panel.

[0116] In the related art, only one trigger portion 82 is provided on the keycap 81, and two cantilevers 91 are provided corresponding to the trigger portion 82 at the same time. When the keycap 81 is subjected to pressing force, one trigger portion 82 applies a force to the two cantilevers 91 at the same time, which causes the two cantilevers 91 to bend and deform synchronously, resulting in the two cantilevers 91 being relatively close in bending deformation or the same, so that the electronic device 10 cannot accurately identify the placement position of the finger 200, and further causes the electronic device 10 to be unable to implement a sliding operation. In the embodiment of the present application, each trigger portion 82 is independent and each cantilever 91 is independent, and the trigger portion 82 is individually provided with a cantilever 91, which can effectively avoid the above-mentioned problem, so that the electronic device 10 can implement a sliding operation through the key 80.

[0117] In the electronic device 10 of the embodiment of the present application, a button 80 is provided on the housing 30. The button 80 is provided corresponding to the switch assembly 70. When the user's finger 200 is placed at a predetermined position of the keycap 81 and remains motionless, and a large pressing force is applied to the keycap 81 of the button 80, the keycap 81 can drive the corresponding trigger part 82 to move to trigger the conductive member 71 of the switch assembly 70, so that the electronic device 10 can implement the pressing operation of the button 80, for example, single-clicking the button 80 or double-clicking the button 80. After the user's finger 200 is placed at a predetermined position of the keycap 81, it can slide on the keycap 81. At this time, the pressing force applied by the finger 200 to the keycap 81 of the button 80 is relatively small, so that the corresponding trigger part 82 moves but can not trigger the conductive member 71 to realize the conduction of the switch assembly 70. During the sliding process of the user's finger 200, different trigger parts 82 can respectively apply forces to the corresponding cantilever 91. Each sensor 101 of the detection component 100 can respectively detect the bending deformation of each cantilever 91 to determine the first position and the second position of the finger 200. The electronic device 10 can generate sliding operation information based on the information of the first position and the second position, so that the electronic device 10 can respond to the sliding operation information to perform the corresponding function. Therefore, the electronic device 10 can implement the sliding operation through the button 80. The button 80 in the electronic device 10 of the embodiment of the present application can implement the pressing operation and the sliding operation at the same time, so that the operation mode and function of the button 80 are diversified, which is conducive to improving the operation experience of the electronic device 10.

[0118] In some achievable ways, the number of trigger parts 82 can be two. The two trigger parts 82 are respectively located on both sides of the center point S of the keycap 81. The arrangement of the two trigger parts 82 being arranged at intervals and the two trigger parts 82 being respectively located on both sides of the center point S of the keycap 81 further reduces the possibility of mutual influence between the two trigger parts 82. When a pressing force is applied to an area on the keycap 81 corresponding to one trigger part 82, the pressing force is not easily transmitted through the keycap 81 to another trigger part 82 away from the pressing position, so that the trigger part 82 away from the pressing position may not move or move a small amount.

[0119] In some examples, the two triggering parts 82 are symmetrically arranged relative to the center point S of the keycap 81. The structures and sizes of the two triggering parts 82 can be the same, which is conducive to ensuring the consistency of the structures and sizes of the two. The cantilever assembly 90 may include two cantilevers 91. The two cantilevers 91 are symmetrically arranged relative to the center point S of the keycap 81. The structures and sizes of the two cantilevers 91 can be the same, which is conducive to ensuring the consistency of the structures and sizes of the two, and reducing the possibility of adverse effects on the detection results of the detection assembly 100 due to differences in the structures and sizes of the two.

[0120] Along the arrangement direction X of the triggering portion 82, the movable end 912 of one cantilever 91 can be arranged facing the movable end 912 of the other cantilever 91. The fixed portion 911 and the movable end 912 of the cantilever 91 are distributed along the arrangement direction X of the triggering portion 82. Exemplarily, along the arrangement direction X of the triggering portion 82, there is a spacing between the movable end 912 of one cantilever 91 and the movable end 912 of the other cantilever 91, and the two do not contact each other. Along the arrangement direction X of the triggering portion 82, the fixed portion 911 is located on one side of the triggering portion 82. The two triggering portions 82 include a first triggering portion and a second triggering portion. Among them, the triggering portion 82 on the left can be used as the first triggering portion, and the triggering portion 82 on the right can be used as the second triggering portion. Along the arrangement direction X of the two triggering portions 82, the fixed portion 911 of one cantilever 91 is located at one end of the first triggering portion away from the second triggering portion, and the fixed portion 911 of the other cantilever 91 is located at one end of the second triggering portion away from the first triggering portion.

[0121] The key cap 81 has two opposite ends along the arrangement direction X of the triggering portions 82 . One triggering portion 82 is disposed at one end of the key cap 81 , and the other triggering portion 82 is disposed at the other end of the key cap 81 .

[0122] Fig.10 The schematic diagram shows the partial structure of the key device. Fig.10 As shown, the two triggering parts 82 include a first triggering part and a second triggering part. Among them, the triggering part 82 on the left can be used as the first triggering part, and the triggering part 82 on the right can be used as the second triggering part. Along the arrangement direction X of the triggering part 82, the minimum distance between the first triggering part and the second triggering part is K0, and the minimum distance between the first triggering part and the end edge of the keycap 81 close to the first triggering part is K1, and the minimum distance between the second triggering part and the end edge of the keycap 81 close to the second triggering part is K2. Among them, K1 and K2 are both less than K0. Exemplarily, K1 can be equal to K2. In the key 80 of this embodiment, the minimum distance between the two triggering parts 82 is relatively large, so that the size of the part of the keycap 81 located between the two triggering parts 82 is relatively large. Therefore, when a pressing force is applied to the area above one triggering part 82 on the keycap 81, the area above the other triggering part 82 on the keycap 81 is not easy to deform synchronously, so that the keycap 81 is not easy to drive the triggering part 82 away from the pressing position to move.

[0123] In some examples, the sensor 101 of the detection assembly 100 can be arranged on the side of the trigger portion 82 facing the fixed portion 911. Along the arrangement direction X of the trigger portion 82, the sensor 101 is arranged between the movable end 912 of the cantilever 91 and the fixed portion 911. When the trigger portion 82 drives the corresponding movable end 912 to move, the suspended portion of the cantilever 91 between the fixed portion 911 and the trigger portion 82 is prone to bending deformation, which is conducive to improving the detection accuracy of the sensor 101 located between the fixed portion 911 and the trigger portion 82. Exemplarily, the sensor 101 is arranged in the area between the fixed portion 911 and the trigger portion 82 on the cantilever 91.

[0124] In some examples, Fig.11 The partial cross-sectional structure of the key device is schematically shown. Fig.12 The partial cross-sectional structure of the electronic device 10 is schematically shown. Fig.11 and Fig.12 As shown, the movable end 912 of at least one cantilever 91 has a through hole 91a. The corresponding trigger portion 82 can be inserted into the through hole 91a, so that the cantilever 91 and the trigger portion 82 can limit and constrain each other, thereby reducing the possibility that the relative position of the trigger portion 82 and the cantilever 91 will be greatly offset during the movement of the cantilever 91 driven by the trigger portion 82, resulting in a large error in the bending deformation of the cantilever 91. Exemplarily, the through hole 91a of the movable end 912 can be a circular hole. The portion of the trigger portion 82 located in the through hole 91a is cylindrical. Exemplarily, the trigger portion 82 and the cantilever 91 are snap-fitted. For example, the trigger portion 82 has a limiting recess 821 (see Fig.10 ). The trigger portion 82 is inserted into the through hole 91a, and a portion of the cantilever 91 is inserted into the limiting recess 821 of the trigger portion 82, so as to realize the locking of the trigger portion 82 and the cantilever 91. Exemplarily, the limiting recess 821 on the trigger portion 82 can be annular. The cross-sectional profile of the limiting recess 821 can be arc-shaped. Exemplarily, among all the cantilevers 91, the movable end 912 of each cantilever 91 has a through hole 91a.

[0125] In some examples, the housing 30 has a welding portion. The fixing portion 911 of the cantilever 91 is welded to the welding portion on the housing 30 to achieve fixing of the fixing portion 911 on the housing 30. Exemplarily, the housing 30 includes a middle frame 31. The welding portion is provided on the middle frame 31. The fixing portion 911 is welded to the welding portion on the middle frame 31. Exemplarily, the material of the cantilever 91 and the material of the welding portion are both metal materials. For example, the material of the cantilever 91 and the material of the welding portion are both steel.

[0126] In some examples, the fixing portion 911 of at least one cantilever 91 is detachably connected to the housing 30, which helps to reduce the difficulty of assembling or disassembling the cantilever 91 and the housing 30, facilitates the maintenance or replacement of the cantilever 91 separately, and improves the maintenance convenience of the electronic device 10. Fig.12 As shown, the cantilever assembly 90 further includes a fastener 92. The fixing portion 911 can be detachably connected to the housing 30 via the fastener 92.

[0127] Exemplarily, the fixing portion 911 has a mounting hole 91b (see Fig.11 The fastener 92 is inserted into the assembly hole 91b. The fastener 92 connects the fixing portion 911 and the housing 30. The fastener 92 can effectively limit the fixing portion 911, thereby reducing the possibility that the relative position between the cantilever 91 and the housing 30 is easily changed due to the looseness and shaking of the fixing portion 911.

[0128] For example, the assembly hole 91b may be a round hole. The fastener 92 may be, but is not limited to, a screw.

[0129] Exemplarily, among all the cantilevers 91 , the fixing portion 911 of each cantilever 91 is detachably connected to the housing 30 .

[0130] For some examples, see Fig.12 As shown, a sensor 101 is disposed on a side of at least one cantilever 91 facing away from the key cap 81. Alternatively, Fig.13 The schematic diagram shows the partial structure of the key device. Fig.13 As shown, a sensor 101 is disposed on a side of at least one cantilever 91 facing the key cap 81. Alternatively, Fig.14 The schematic diagram shows the partial structure of the key device. Fig.14 As shown, sensors 101 are respectively arranged on a side of at least one cantilever 91 facing the key cap 81 and a side facing away from the key cap 81 .

[0131] Exemplarily, among all the cantilevers 91, a sensor 101 is provided on the side of each cantilever 91 facing the keycap 81. Alternatively, among all the cantilevers 91, a sensor 101 is provided on the side of each cantilever 91 facing away from the keycap 81. Alternatively, among all the cantilevers 91, a sensor 101 is provided on the side of each cantilever 91 facing the keycap 81 and the side facing away from the keycap 81, respectively.

[0132] Exemplarily, the sensor 101 and the cantilever 91 are connected by bonding.

[0133] In some achievable ways, Fig.15 for Fig.12 Enlarged view of M in the middle. Fig.12 and Fig.15As shown, there is a gap between at least one trigger portion 82 and the conductive member 71 corresponding to the trigger portion 82. The spacing between at least one trigger portion 82 and the conductive member 71 corresponding to the trigger portion 82 is L1. When the keycap 81 of the key 80 is not pressed, there is a spacing (L1) between the trigger portion 82 and the corresponding conductive member 71, so that the trigger portion 82 and the conductive member 71 do not contact each other. When the user needs to perform a sliding operation through the key 80, the keycap 81 is pressed. Since there is a spacing (L1) between the trigger portion 82 and the corresponding conductive member 71, the keycap 81 can relatively easily drive the trigger portion 82 to move, which is beneficial to improve the sensitivity of the trigger portion 82 to drive the movable end 912 to move. When the distance moved by the trigger part 82 is less than the distance (L1) between the trigger part 82 and the corresponding conductive part 71, the conductive part 71 will not apply a reaction force to the trigger part 82, so that the trigger part 82 does not need to overcome the reaction force of the conductive part 71, so that a smaller pressing force is applied to the keycap 81, and the cantilever 91 can be driven to bend and deform through the trigger part 82.

[0134] For example, the distance (L1) between the trigger portion 82 and the corresponding conductive member 71 may be 0.08 mm to 0.13 mm. For example, the distance (L1) between the trigger portion 82 and the corresponding conductive member 71 may be 0.1 mm.

[0135] Exemplarily, among all the triggering parts 82 , there is a gap between each triggering part 82 and the corresponding conductive member 71 .

[0136] In some achievable embodiments, a conductive member 71 is disposed on a side of the movable end 912 of at least one cantilever 91 facing away from the keycap 81. A spacing is provided between the movable end 912 and the conductive member 71. Exemplarily, in all cantilevers 91, a conductive member 71 is disposed on a side of the movable end 912 of each cantilever 91 facing away from the keycap 81.

[0137] In some achievable ways, there is a gap between the cantilever 91 and the keycap 81. The distance between the cantilever 91 and the keycap 81 is L2. After the keycap 81 is pressed, the keycap 81 drives the trigger part 82 to move, and the keycap 81 moves close to the cantilever 91. Since there is a distance (L2) between the cantilever 91 and the keycap 81, it is not easy for the keycap 81 to contact the cantilever 91. If the keycap 81 contacts the cantilever 91, the cantilever 91 will be bent and deformed by the trigger part 82 and the keycap 81 at the same time. When the cantilever 91 is acted on by the trigger part 82 alone, the cantilever 91 is bent and deformed so that the cantilever 91 is in a first bending state. When the cantilever 91 is acted on by the trigger part 82 and the keycap 81 at the same time, the cantilever 91 is bent and deformed so that the cantilever 91 is in a second bending state. There is a possibility that the bending deformation amounts of the cantilever 91 in the first bending state and the second bending state are different, so there is a possibility that the detection result of the sensor 101 will be wrong or biased, affecting the detection accuracy of the sensor 101.

[0138] Exemplarily, the keycap 81 includes a boss 811. The boss 811 is located at the end of the keycap 81. The bosses 811 are respectively arranged at the two ends of the keycap 81. At least two triggering parts 82 are located between the two bosses 811. The boss 811 is arranged facing the cantilever 91. There is a gap between the cantilever 91 and the boss 811. The distance between the boss 811 and the keycap 81 is L2.

[0139] In some achievable embodiments, at least one trigger portion 82 and the cantilever 91 corresponding to the trigger portion 82 are an integrally formed structure. The integral structure formed by the corresponding trigger portion 82 and the cantilever 91 has high mechanical strength, so that the trigger portion 82 and the cantilever 91 are not easily separated. There is no assembly gap between the integrally formed trigger portion 82 and the cantilever 91, which improves the movement synchronization of the trigger portion 82 and the cantilever 91, so that when the trigger portion 82 moves, the trigger portion 82 can synchronously drive the cantilever 91 to bend and deform.

[0140] Exemplarily, among all the trigger parts 82, each trigger part 82 is an integrally formed structure with the corresponding cantilever 91. For example, the number of the trigger parts 82 may be two. The number of the cantilever 91 may be two. The trigger part 82 on the left is an integrally formed structure with the cantilever 91 on the left, and the trigger part 82 on the right is an integrally formed structure with the cantilever 91 on the right.

[0141] In some achievable ways, at least one trigger part 82 is snap-fitted to the cantilever 91 corresponding to the trigger part 82. The trigger part 82 and the cantilever 91 are detachably connected by snap-fitting. The trigger part 82 and the cantilever 91 are directly connected by a snap-fitting structure, and no additional connecting parts are required to achieve the connection, which is beneficial to reducing the number of parts used and reducing the difficulty of assembly. In addition, one of the trigger part 82 and the cantilever 91 can be repaired or replaced separately, which is beneficial to reducing the difficulty and cost of maintenance. Exemplarily, the trigger part 82 has a limiting recess 821. The cantilever 91 has a through hole 91a. The trigger part 82 is inserted into the through hole 91a of the cantilever 91, and a part of the cantilever 91 is snapped into the limiting recess 821 to achieve snap-fitting.

[0142] Exemplarily, among all the triggering parts 82 , each triggering part 82 is engaged with the corresponding cantilever 91 .

[0143] In some achievable ways, at least one cantilever 91 is a sheet structure. Along the thickness direction of the cantilever 91, the trigger portion 82 is located on one side of the keycap 81. When the cantilever 91 of the sheet structure is subjected to the force of the trigger portion 82, the cantilever 91 is prone to bending deformation, and when subjected to the force along its own thickness direction, it is easy to produce a relatively large bending deformation, which is conducive to the sensor 101 accurately detecting the bending deformation amount of the cantilever 91, and improving the detection precision and accuracy. Exemplarily, the cantilever 91 has a through hole 91a. The thickness direction of the cantilever 91 is the same as the axial direction of the through hole 91a. The trigger portion 82 is penetrated through the through hole 91a. Along the thickness direction of the cantilever 91, there is a spacing between the cantilever 91 and the conductive member 71. The trigger portion 82 is located at the end of the cantilever 91 facing away from the keycap 81 for contacting the conductive member 71. Exemplarily, the trigger portion 82 is a columnar structure. The axial direction of the trigger portion 82 is the same as the thickness direction of the cantilever 91. Exemplarily, the arrangement direction X of the triggering portion 82 is perpendicular to the thickness direction of the cantilever 91 .

[0144] Exemplarily, among all the cantilevers 91 , each cantilever 91 is a sheet-like structure.

[0145] In some achievable embodiments, at least one sensor 101 includes a strain gauge, so that the detection sensitivity of the sensor 101 itself is high, which is conducive to ensuring the precision and accuracy of the detection result. Exemplarily, the sensor 101 can be set on the cantilever 91 by bonding. For example, the sensor 101 and the cantilever 91 can be bonded with adhesive. Exemplarily, the sensor 101 can include a piezoresistive strain gauge. For example, the sensor 101 can include a resistance strain gauge. The number of sensors 101 set on each cantilever 91 is at least one. Exemplarily, the number of sensors 101 on each cantilever 91 can be four. Four sensors 101 can form a full-bridge circuit.

[0146] A sensor 101 may be provided on the side of the cantilever 91 facing the keycap 81. When the user presses the keycap 81, the keycap 81 drives the trigger portion 82 to move, thereby driving the cantilever 91 to bend and deform. The sensor 101 provided on the side of the cantilever 91 facing the keycap 81 is stretched by force, so that the resistance of the sensor 101 changes, and the bending deformation of the cantilever 91 can be obtained by detecting the output voltage of the full-bridge circuit.

[0147] Alternatively, a sensor 101 may be provided on the side of the cantilever 91 facing away from the keycap 81. When the user presses the keycap 81, the keycap 81 drives the trigger portion 82 to move, thereby driving the cantilever 91 to bend and deform. The sensor 101 provided on the side of the cantilever 91 facing away from the keycap 81 is compressed by force, so that the resistance of the sensor 101 changes, and the bending deformation of the cantilever 91 can be obtained by detecting the output voltage of the full-bridge circuit.

[0148] Alternatively, a sensor 101 is provided on the side of the cantilever 91 facing the keycap 81, and a sensor 101 is also provided on the side of the cantilever 91 facing away from the keycap 81. For example, when a user presses the keycap 81, the keycap 81 drives the trigger portion 82 to move, thereby driving the cantilever 91 to bend and deform. The sensor 101 provided on the side of the cantilever 91 facing the keycap 81 is stretched by force, while the sensor 101 provided on the side of the cantilever 91 facing away from the keycap 81 is compressed by force, so that the resistance of the sensor 101 changes, so that the bending deformation of the cantilever 91 can be obtained by detecting the output voltage of the full-bridge circuit.

[0149] In some achievable ways, Fig.16 The partial structure of the key device is schematically shown. Fig.17 The schematic diagram shows the partial structure of the key device. Fig.16 and Fig.17 As shown, the button 80 includes three triggering parts 82 and three cantilevers 91. The three triggering parts 82 can be arranged at intervals along the arrangement direction X. Fig.16 The positions shown are for reference, the triggering part 82 on the left can be used as the first triggering part. The triggering part 82 on the right can be used as the second triggering part. The triggering part 82 in the middle can be used as the third triggering part. The sensor 101 on the left can be used as the first sensor. The sensor 101 on the right can be used as the second sensor. The sensor 101 in the middle can be used as the third sensor. The cantilever 91 on the left can be used as the first cantilever. The cantilever 91 on the right can be used as the second cantilever. The cantilever 91 in the middle can be used as the third cantilever.

[0150] Exemplarily, the user's finger 200 is placed on the keycap 81 in an area near the first trigger portion. When the first sensor detects that the first cantilever is bent and deformed, the first sensor detects the bending deformation of the first cantilever, and the first sensor outputs a detection signal. The second sensor detects the bending deformation of the second cantilever, and outputs a detection signal. The third sensor detects the bending deformation of the third cantilever, and outputs a detection signal. The bending deformation of the first cantilever is greater than the bending deformation of the second cantilever. Furthermore, the bending deformation of the first cantilever is greater than the bending deformation of the third cantilever. The current position of the finger 200 is determined to be the first position.

[0151] The first sensor detects that the bending deformation of the first cantilever changes from large to small. When the third sensor detects that the bending deformation of the third cantilever changes from small to large, it is determined that the finger 200 slides on the key cap 81 and slides toward the third triggering portion.

[0152] When the finger 200 slides to the top of the third trigger part, the bending deformation of the third cantilever reaches the maximum. After the finger 200 slides over the third trigger part, the third sensor detects that the bending deformation of the third cantilever changes from large to small. When the second sensor detects that the bending deformation of the second cantilever continues to increase, it is determined that the finger 200 continues to slide toward the second trigger part.

[0153] When the first sensor detects that the bending deformation of the first cantilever no longer changes. The second sensor detects that the bending deformation of the second cantilever no longer changes. The third sensor detects that the bending deformation of the third cantilever no longer changes. It is determined that the finger 200 stops sliding, and the current position of the finger 200 is the second position. The electronic device 10 can generate sliding operation information based on the information of the first position and the second position.

[0154] Exemplarily, the middle trigger portion 82 may be located below the center point S of the keycap 81. The three trigger portions 82 may be arranged at equal intervals along the arrangement direction X, that is, the minimum distance between the trigger portion 82 on the left and the trigger portion 82 in the middle is equal to the minimum distance between the trigger portion 82 on the right and the trigger portion 82 in the middle.

[0155] In some achievable ways, Fig.18 A partial structure of the electronic device 10 is schematically shown. Fig.18 The partial structure of the electronic device 10 is schematically shown. Fig.18As shown, the electronic device 10 also includes a linear motor 110. The linear motor 110 can provide a vibration sense for the electronic device 10, thereby providing tactile feedback for the user to enhance the user's tactile experience of the electronic device 10. The linear motor 110 can provide a variety of vibration modes, so that the user can experience different tactile feedback to enrich the user experience of the electronic device 10. Exemplarily, the linear motor 110 can be an X-axis vibration motor. The linear motor 110 can drive the vibrator to reciprocate through the principle of electromagnetic induction to generate a corresponding vibration sense.

[0156] The electronic device 10 also includes a controller 120. The sensor 101 and the linear motor 110 are respectively connected to the controller 120 for communication. When the sensor 101 detects the current bending deformation of the cantilever 91, the sensor 101 can output a detection signal. The sensors 101 on different cantilevers 91 can send detection signals to the controller 120 respectively. When the user's finger 200 slides on the keycap 81, the bending deformation of different cantilevers 91 changes in real time. By detecting the change in the bending deformation of each cantilever 91, the sliding distance of the user's finger 200 can be obtained.

[0157] In some feasible embodiments, after the user's finger 200 slides a predetermined distance on the keycap 81, different sensors 101 send detection signals to the controller 120 respectively, and the controller 120 simultaneously controls the linear motor 110 to turn on, so as to provide vibration tactile feedback to the user, so that the user can judge the current sliding distance of the finger 200, thereby improving the user experience of the electronic device 10.

[0158] In some examples, the user performs a sliding motion on the keycap 81, and the distance between the first position and the second position is 20 mm. When the user's finger 200 slides 2 mm on the keycap 81, the linear motor 110 is turned on once to provide a vibration tactile feedback to the user. When the user's finger 200 slides from the first position to the second position, the linear motor 110 is turned on 10 times in total.
