Referring to fig. 1, a schematic diagram of a part of a structure of an electronic device according to an embodiment of the present application may specifically include: a bezel 10 and a key assembly;

The key assembly includes a key cap 20, a connection plate 30, and a sensor 40;

The frame 10 is provided with an opening 11, the connecting plate 30 is connected to the opening 11 of the frame 10, and the key cap 20 is embedded in the opening 11 and connected to the connecting plate 30;

The sensor 40 is connected to the connection plate 30, and when the sensor 40 detects that the pressure applied to the key cap 20 is transmitted to the connection plate 30, the key cap 20 is triggered to generate vibration.

In the embodiment of the application, by connecting the keycap 20 to the connecting plate 30, the keycap 20 is not required to be movably connected to the fixed plate of the frame 10, so that a larger movement stroke between the keycap 20 and the fixed plate is avoided, and the problems of easy blocking, sinking or unsuccessful pressing of the keycap 20, virtual position and the like of the keycap 20 are avoided. Specifically, when the key cap 20 is subjected to external pressure, the pressure is transmitted to the connection plate 30, the sensor 40 is connected to the connection plate 30, and the pressure transmitted to the connection plate 30 by the key cap 20 is detected to generate mechanical vibration, so as to trigger the corresponding functions of the key cap 20, such as power on, power off, screen lighting, screen extinction, volume adjustment, screen capturing or quick start, etc. In addition, since the pressure transmitted to the connecting plate 30 by the key cap 20 is sensed by the sensor 40 in the embodiment of the application, the function of the key cap 20 can be triggered without pressing the key cap 20 to move towards the fixed plate so that the convex blocks on the key cap 20 are abutted against the dome on the fixed plate, so that the key cap 20 can transmit the pressure to the sensor 40 by the connecting plate 30 under the conditions of touching, clicking, sliding, pressing and the like, and the triggering mode and the function of the key cap 20 are enriched.

For example, in the embodiment of the present application, the function corresponding to the key cap 20 being touched once may be set to be on screen, the function corresponding to the key cap being touched twice may be set to be off screen, and the function corresponding to the key cap 20 being slid on may be set to be on volume, for example, up to turn up volume and down to turn down volume. Different functions of the key cap 20 may be set according to the touch time, for example, the key cap is turned off or turned on after being touched for more than three seconds, which is not limited in the embodiment of the present application.

In the embodiment of the present application, the frame 10 may be also referred to as a middle frame, for example, to support the overall structure of the electronic device. The key cap 20 may be a key cap for receiving external forces such as touch, click, slide, and press applied by a user. The connecting plate 30 may be a steel sheet, which has a better force transmission effect, and when the key cap 20 receives an external force from a user, the steel sheet may have a better transmission effect on the external force, for example, the steel sheet may have elastic deformation so as to generate pressure change, so that the sensor 40 is convenient to detect the external force received by the key cap 20 through the deformation of the steel sheet, for example, the force application size, the force application position, and the like.

Specifically, in the embodiment of the present application, the sensor 40 may be a pressure sensor, which can detect the change of the pressure caused by the external force transmitted from the key cap 20 to the connecting plate 30, or the time of the pressure, so as to have better sensing sensitivity, so as to conveniently detect the touch, sliding, and so on operation of the key cap 20. For example, the sensor 40 may be adhered to the connection board 30 by an adhesive such as double-sided tape, so that the sensor 40 and the connection board 30 have good connection reliability and simple operation. In addition, the sensor 40 may be connected to the connection board 30 by other manners, such as welding, and the specific connection manner between the sensor 40 and the connection board 30 in the embodiment of the present application may not be limited.

Specifically, in the embodiment of the present application, the opening 11 on the frame 10 is used for accommodating the keycap 20, and the opening 11 is matched with the keycap 20, that is, the size and shape of the opening and the keycap are the same or similar, and the frame 10 and the keycap 20 can be flush, so that the electronic device has better flatness and aesthetic property in appearance. For example, the shape of the opening 11 may be concave, rectangular, or the like, and the specific shape of the opening 11 may not be limited in the embodiment of the present application.

Optionally, in the embodiment of the present application, the electronic device further includes a soft magnetic member 50 and an inductor 60, the soft magnetic member 50 is connected to a side of the connecting plate 30 away from the keycap 20, the inductor 60 is movably connected to the soft magnetic member 50, and the inductor 60 is electrically connected to the sensor 40; in the case where the sensor 40 detects that the pressure applied to the key cap 20 is transmitted to the connection plate 30, the inductor 60 is energized and moves toward the soft magnetic member 50, and the soft magnetic member 50 generates vibration and transmits the vibration to the key cap 20 along the connection plate 30, so that the key cap 20 generates trigger feedback. In this way, when the key cap 20 realizes the corresponding function, the inductor 60 is electrified to generate magnetic force, and magnetic attraction is generated between the inductor 60 and the soft magnetic piece 50, so that the inductor 60 moves towards the soft magnetic piece 50, the soft magnetic piece 50 is impacted to generate vibration, and the vibration is transmitted to the key cap 20 through the connecting plate 30 to generate triggering feedback, and a user can feel the triggering feedback through the key cap 20 to confirm successful triggering of the key cap 20 function.

For example, in the embodiment of the present application, the soft magnetic member 50 may be connected to the connecting plate 30 by laser welding, so that the soft magnetic member 50 has better connection reliability and stability, and in addition, the soft magnetic member 50 may also be adhered to the connecting plate 30 by using an adhesive, such as a double sided adhesive tape or a structural adhesive, etc., and the specific connection manner of the soft magnetic member 50 to the connecting plate 30 in the embodiment of the present application may not be limited.

Specifically, in the embodiment of the present application, the soft magnetic member 50 refers to an object whose magnetization occurs at a coercive force (Hc) of not more than 1000 (a/m), and can achieve maximum magnetization with a minimum external magnetic field, having a low coercive force and a high magnetic permeability. The use of hard magnetic elements to cause greater vibrations of the connection plate 30 to affect the user experience is avoided. For example, the soft magnetic member 50 may be an iron-silicon alloy, an iron-aluminum alloy, a nickel-iron alloy, an iron-cobalt alloy, an ultra-microcrystalline soft magnetic alloy, a silicon steel sheet, or a soft magnetic ferrite lamp strip, and the specific material of the soft magnetic body may not be limited in the embodiments of the present application.

In an embodiment of the present application, optionally, the electronic device further includes a guide post 70, where the guide post 70 is connected to the soft magnetic component 50, and the inductor 60 is sleeved on the guide post 70 and is slidingly connected to the guide post 70. In this way, the guide post 70 realizes the movable connection between the inductor 60 and the soft magnetic member 50, and the inductor 60 slides along the guide post 70 with better stability and reliability. The guide post 70 may be a cylinder, a cuboid, or the like, and the specific type of the guide post 70 may not be limited in the embodiment of the present application.

In some alternative embodiments of the present application, a stopper may be disposed at an end of the guide post 70 remote from the soft magnetic member 50, and the disposition position of the inductor 60 on the guide post 70 is restricted by the stopper, so that the inductor 60 slides between the stopper of the guide post 70 and an end thereof near the soft magnetic member 50. The limiting piece can be a limiting plate or a limiting block and the like, and the specific type of the limiting piece is not limited in the embodiment of the application.

Specifically, in the embodiment of the present application, the inductor 60 includes a housing 61, a coil 62, and a bushing 63; the coil 62 is disposed in the housing 61, the bushing 63 is embedded in a side of the coil 62 away from the housing 61, and the bushing 63 is sleeved on the guide post 70 and slidably connected to the guide post 70. In this way, the coil 62 is protected by the housing 61, adverse effects caused by interference of the coil 62 with other structures are avoided, and the connection between the inductor 60 and the guide post 70 is realized by the bushing 63, so that the application effect of the inductor 60 is prevented from being influenced by abrasion easily caused by directly sliding the coil 62 to the guide post 70.

Optionally, in an embodiment of the present application, the electronic device further includes a buffer member 51, where the buffer member 51 is connected to a side of the soft magnetic member 50 near the inductor 60, so as to buffer the movement of the inductor 60 toward the soft magnetic member 50. In this way, the impact of the inductor 60 on the soft magnetic member 50 can be reduced through the buffer member 51, and on the basis that the connecting plate 30 can transmit the feedback of the key cap 20 to the key cap 20, the electronic device can generate smaller vibration to avoid noise from affecting the user experience.

In an embodiment of the present application, optionally, the electronic device further includes an elastic member 52, where the elastic member 52 is connected between the soft magnetic member 50 and the inductor 60; in the case that the sensor 40 does not detect that the pressure applied to the key cap 20 is transmitted to the connecting plate 30, the inductor 60 is powered off, and the elastic member 52 drives the inductor 60 to move away from the soft magnetic member 50. In this way, when the key cap 20 is not pressed by external force, the inductor 60 is powered off and the magnetic field is finally disappeared, no magnetic attraction exists between the inductor 60 and the soft magnetic member 50, the inductor 60 is driven to move away from the soft magnetic member 50 by the elastic force of the elastic member 52, and the key cap is restored to the initial position so as to be ready for the next triggering feedback of the key cap 20.

Optionally, in an embodiment of the present application, the electronic device further includes a processor electrically connected to the sensor 40 and the inductor 60, respectively, and the processor controls the inductor 60 to be powered on or off based on the pressure detected by the sensor 40. Specifically, when the pressure detected by the sensor 40 is greater than zero, that is, when the key cap 20 is subjected to external pressure, the sensor 40 transmits a pressure signal to the processor, the processor receives the pressure signal and then controls the inductor 60 to be electrified, and the inductor 60 generates a magnetic field to magnetically adsorb the soft magnetic member 50, so that the inductor 60 moves towards the soft magnetic member 50, and the soft magnetic member 50 is impacted to generate vibration to realize triggering feedback of the key cap 20. When the pressure detected by the sensor 40 is zero, that is, when the key cap 20 is not subjected to external pressure, the sensor 40 transmits a pressure signal to the processor, the processor receives the pressure signal and then controls the inductor 60 to be powered off, and finally the magnetic field of the inductor 60 disappears, the inductor 60 and the soft magnetic member 50 do not have magnetic attraction force, and the inductor 60 is driven to move away from the soft magnetic member 50 by the elastic force of the elastic member 52, so that the inductor 60 is restored to the initial position.

For example, in the embodiment of the present application, when the key cap 20 receives different external pressures, the sensor 40 may transmit different pressure signals to the processor, and the processor may correspondingly output different electrical signals when receiving the pressure signals, so that the power-on strength of the inductor 60 is different, or the power-on time is different, so that the force or frequency of the movement of the inductor 60 towards the soft magnetic member 50 is different, so as to implement triggering feedback of different key cap 20 functions, and improve the accuracy and richness of the feedback function of the key cap 20.

In some alternative embodiments of the present application, a gap is provided between the key cap 20 and the opening 11 to avoid the pressure applied to the key cap 20 from being transferred to the frame 10. Like this for when keycap 20 receives the external force such as touch, click, slip and press that the user applyed, owing to be equipped with the clearance between the opening 11 of keycap 20 and frame 10, the vibration that above-mentioned keycap 20 received external force to produce can not directly transmit to frame 10, reduced the vibration that frame 10 produced, promoted user experience.

Alternatively, in the embodiment of the present application, the sensor 40 includes a first sensor 41 and a second sensor 42, the first sensor 41 is connected to one end of the connection board 30, and the second sensor 42 is connected to the other end of the connection board 30. In this way, the first sensor 41 and the second sensor 42 can respectively detect the pressure transmitted to the two ends of the connecting plate 30 by the keycap 20, when the user applies an external force near one end of the keycap 20, the pressure is transmitted to the connecting plate 30, the pressure detected by the first sensor 41 is greater than the pressure detected by the second sensor 42, one keycap 20 function can be correspondingly arranged, when the user applies an external force near the other end of the keycap 20, the pressure detected by the second sensor 42 is greater than the pressure detected by the first sensor 41, the other keycap 20 function can be correspondingly arranged, and the triggering mode and the triggering function of the keycap 20 are further enriched.

In an embodiment of the present application, optionally, the electronic device further includes a first fastener 80 and a second fastener 81; the first fastener 80 sequentially penetrates through the connecting plate 30 and the keycap 20 to fix the keycap 20 to the connecting plate 30; the second fastening member 81 sequentially penetrates through the connecting plate 30 and the frame 10 to fix the connecting plate 30 to the frame 10. In this way, the connection reliability and stability between the key cap 20 and the connection plate 30 are improved by the first fastener 80, and the connection reliability and stability between the connection plate 30 and the frame 10 are improved by the first fastener 80, which is simple and reliable, and convenient to operate.

In addition, the number of the first fasteners 80 may be 1 or 2, 3, etc., and the plurality of first fasteners 80 may be distributed at intervals, and the specific number and arrangement manner of the first fasteners 80 may not be limited in the embodiment of the present application.

Likewise, the second fastening member 81 may also include bolts, studs, screws, etc., and the embodiment of the present application may not be limited to the specific type of the second fastening member 81.
