[0033] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0034] In the related art, electronic devices usually have side buttons or home screen buttons (such as the HOME button), which not only have basic switch functions, but also need to carry complex functions such as fingerprint recognition. To achieve these functions, the internal structure and stacking of the button structure will be very complex. The typical structure includes the stacking of multiple components such as the button housing, circuit board, and fingerprint sensor.

[0035] This complex laminated structure makes it more difficult to control the tolerances between components during production and assembly. Due to the matching issues between multiple components, the cumulative tolerance will be larger. When the cumulative tolerance exceeds a certain range, a gap will be generated between the key structure and the electronic device, which will cause the key structure to become loose after assembly. Loose keys will reduce the user experience of electronic devices and also cause poor signal transmission, affecting the normal function of the keys.

[0036] In order to solve the above technical problem, a key structure 1 is provided according to an embodiment of the present disclosure.

[0037] Figure 1 A schematic diagram of an electronic device is shown according to an exemplary embodiment. Figure 2 yes Figure 1 Schematic diagram of the cross-section of the structure of part A. Figure 3 The figure is a front view of a key structure and a switch assembly according to an exemplary embodiment.

[0038] In some embodiments, Figure 1 As shown, the key structure 1 can be arranged in the electronic device 100, such as Figure 2 or Figure 3 As shown, the key structure 1 mainly includes a key component 2 , a switch component 110 and an elastic component 3 .

[0039] The switch assembly 110 can be used to be triggered by the button assembly 2. The elastic assembly 3 can be arranged between the button assembly 2 and the switch assembly 110. The elastic assembly 3 can include a first side and a second side. The first side can abut the button assembly 2, and the second side can abut the switch assembly 110. The elastic assembly 3 can apply a force to the button assembly 2 away from the switch assembly 110.

[0040] In some embodiments, the button structure 1 may be a volume button or a switch button, etc. The switch component 110 may transmit a corresponding electrical signal based on receiving the pressure of the button component 2, so that the electronic device can adjust the volume, turn off / on the device, etc.

[0041] like Figure 1 or Figure 2 or Figure 3As shown, the button assembly 2 may include a pressing surface 21 and a back surface 22, and the pressing surface 21 may face opposite to the back surface 22. The elastic assembly 3 may be disposed on the back surface 22, and the elastic assembly 3 may be disposed on the electronic device 100. When the elastic assembly 3 is disposed on the electronic device, the elastic assembly 3 may face the main body of the electronic device.

[0042] In the present disclosure, when the key assembly 2 is subjected to an external force, the key assembly 2 may apply a force to the elastic assembly 3. When the key assembly 2 applies a force to the elastic assembly, at least a portion of the elastic assembly 3 may contact the switch assembly 110 to apply a force to the key assembly 2 away from the electronic device 100.

[0043] In this embodiment, the assembly tolerance of the key structure 1 is absorbed by the elastic deformation characteristic of the elastic component 3. Since the elastic component 3 can apply a force to the key component 2 away from the switch component 110, if the tolerance between the key component 2 and the switch component 110 is large, the deformation of the elastic component 3 can be increased accordingly. If the tolerance between the key component 2 and the switch component 110 is small, the deformation of the elastic component 3 can be reduced accordingly. In this way, the tolerance between the key component 2 and the switch component 110 will not affect the looseness of the key component 2, thereby preventing the key structure 1 from loosening.

[0044] It can be further understood that, in the present disclosure, the elastic component 3 can be in an elastic deformation state, and a restoring force can be provided in the elastic deformation state. This restoring force can act on the key component 2, so that the key component 2 is pushed away from the switch component 110 by the force of the elastic component 3. Through this arrangement, the gap between the switch component 110 and the key component 2 can be occupied by the deformed elastic component 3. In this state, there is no longer a gap between the key component 2 and the switch component 110, and the key component 2 is fixed by the force of the elastic component 3, thereby preventing the key from loosening. When the user presses the key structure 1, the elastic component 3 approaches the switch component 110 under the action of the pressing force to trigger the switch component 110. When the user releases the key, the restoring force of the elastic component 3 can reset the key again, and continue to play a role in preventing the key component 2 from loosening.

[0045] It can be understood that the button assembly 2 is a structural form that can realize the button pressing function. From a structural aspect, the button assembly 2 can be a mechanical button assembly, a piezoelectric button assembly, etc. From a functional aspect, the button assembly 2 can also be a fingerprint recognition button assembly, a power switch button assembly, etc., but the present disclosure does not specifically limit the type of the button assembly 2, that is, those skilled in the art can set or adjust it according to actual conditions, as long as the button assembly 2 can realize the button pressing function.

[0046] Figure 4The figure is a front view of a key structure according to an exemplary embodiment. Figure 5 The figure is a front view of a key structure according to an exemplary embodiment. Figure 6 is a front view of a key structure according to another exemplary embodiment.

[0047] In some embodiments, Figure 4 or Figure 5 or Figure 6 As shown, the button assembly 2 may include a pressing surface 21 and a back surface 22 . The pressing surface 21 may face opposite to the back surface 22 , and the first side of the elastic assembly 3 may abut against the back surface 22 .

[0048] It is understandable that the pressing surface 21 can be the surface of the button assembly 2 for receiving pressing force. In other words, the pressing surface 21 can withstand the pressing force and can transmit the pressing force to the switch assembly 110, thereby triggering the switch assembly 110.

[0049] For example, in one possible situation, Figures 3 to 6 As shown, the key assembly 2 may be a mechanical key assembly 2 having a key housing 24 , and the pressing surface 21 may be the outer top surface of the key housing 24 .

[0050] In another possible case, the key assembly 2 may also be a pressure sensor without a key cap, and the pressing surface 21 may be the force-bearing surface of the sensor.

[0051] In another possible case, the key assembly 2 may also be a non-planar key, and the pressing surface 21 may be a protruding portion of the non-planar key, and the protruding portion is a surface for pressing.

[0052] It is understood that the back surface 22 in the key assembly 2 may be a surface for transmitting the pressing force, and the back surface 22 may be opposite to the pressing surface 21. The back surface 22 may be Figure 1 or Figure 2 The flat side shown can also be Figure 3 As for the arc surface shown, the present disclosure does not specifically limit the shape of the back side 22 , that is, those skilled in the art can set or adjust it according to actual conditions, as long as the back side 22 can transmit the pressing force.

[0053] It is understandable that the switch component 110 can be a switch component suitable for controlling the power supply of the electronic device 100 in the electronic device 100, and the switch component 110 can include a mechanical switch and a circuit board, etc. For example, when the user triggers the switch component 110, the switch component 110 will cut off or connect the power supply of the electronic device, so that the electronic device is turned off or turned on. Alternatively, the switch component 110 will cut off or connect the power supply of the display module in the electronic device, so that the display module of the electronic device turns on or off the screen. Alternatively, the switch component 110 can also be used to restart the electronic device, etc. Alternatively, the switch component 110 can also start a specific function or mode. For example, long pressing the switch component 110 can usually open a menu, allowing the user to choose to shut down, restart, or start the flight mode, etc.

[0054] The circuit board can be a printed circuit board (PCB) or a flexible printed circuit (FPC). The circuit board can receive and process signals from the switch component 110. For example, when the user presses the switch component 110, the electronic components integrated on the circuit board can process these signals and execute corresponding instructions, such as adjusting the volume or turning the machine on and off.

[0055] It can be understood that the elastic component 3 is a structure that can provide a force to the key component 2 and has elastic deformation capability. The elastic component 3 can be any one or more combinations of the following types, such as a metal dome, a spring, rubber, etc., but the present disclosure does not specifically limit the type of the elastic component 3, that is, those skilled in the art can set or adjust it according to actual conditions, as long as the elastic component 3 can provide a force to the key component 2 and has elastic deformation capability.

[0056] In an exemplary embodiment of the present disclosure, the elastic component 3 may include a spring, the first side of the elastic component 3 may be one end of the spring, and the second side of the elastic component 3 may be the other end of the spring. For example, when one end of the spring abuts against the key component 2 and the other end abuts against the switch component 110, the spring releases an elastic force, which may be a force applied by the elastic component 3 to the key component 2 to move away from the switch component 110.

[0057] In an exemplary embodiment of the present disclosure, the elastic component 3 may include rubber, the first side of the elastic component 3 may be one end of the rubber, and the second side of the elastic component 3 may be the other end of the rubber. For example, when one end of the rubber abuts against the key component 2 and the other end abuts against the switch component 110, the rubber releases elastic force, which may be a force applied by the elastic component 3 to the key component 2 to move away from the switch component 110.

[0058] However, the present disclosure is not limited thereto. In another possible case, the elastic component 3 may include a spring sheet, such as Figures 3 to 6 As shown, the elastic component 3 may include a deformation portion 31, and a gap 4 may be formed between the deformation portion 31 and the back surface 22, and the deformation portion 31 may be deformed toward the key component 2. In this embodiment, at least a portion of the elastic component 3 may be the deformation portion 31. The deformation portion 31 of the elastic component 3 may be deformed, and when the deformation portion 31 is deformed, the elastic component 3 may provide a restoring force, so the elastic component 3 may provide a force to the key component 2.

[0059] In the present disclosure, when the key assembly 2 applies a force to the elastic assembly 3 , the deformation portion 31 may apply a force to the key assembly 2 away from the switch assembly 110 .

[0060] In the present disclosure, there may be a gap 4 between the first side of the elastic component 3 and the key component 2. When the key component 2 applies a force to the elastic component 3, the elastic component 3 may deform toward the gap 4. In the present disclosure, the gap 4 is set between the first side of the elastic component 3 and the key component 2, and the existence of the gap 4 provides a space for the elastic component 3 to deform.

[0061] In the present disclosure, the shape of the gap 4 is not limited, as long as the gap 4 can provide a deformation space for the deformation part 31, so that the restoring force acts on the key assembly 2, so that the key assembly 2 is pushed away from the electronic device 100 by the force of the elastic assembly 3, thereby avoiding the loosening of the key structure 1.

[0062] In this disclosure, Figure 4 As shown, a buffer component 42 may be further provided in the gap 4 , and the buffer component 42 may provide a buffer force to control the deformation amount of the elastic component 3 .

[0063] It should be noted that the deformation portion 31 may be a portion of the elastic component 3 that can be elastically deformed. For example, if the elastic component 3 is a spring, the entire structure of the spring may have a certain elastic deformation capability, and both ends of the spring may be fixed to the button component 2 and / or the switch component 110. The deformation capability of the middle portion is the largest, and therefore the middle area of ​​the spring may be regarded as the deformation portion 31. It should be noted that in this embodiment, the position and range of the deformation portion 31 may be determined according to the fixing method of the spring, and the present disclosure does not limit this.

[0064] In one possible case, the back side 22 may be a flat surface, the elastic component 3 may be a spring, a gap 4 may be left between a portion of the elastic component 3 and the back side 22, and another portion of the elastic component 3 may be connected to the back side 22 via a connecting structure (such as bolts, supports, etc.).

[0065] In other possible cases, such as Figure 6 As shown, the back side 22 may also be an arc surface, and the elastic component 3 may also be an arc-shaped spring sheet. A gap 4 may be left between at least a portion of the elastic component 3 and the back side 22, and another portion of the elastic component 3 may be connected to the back side 22 via a connecting structure (such as bolts, supports, etc.).

[0066] It should be noted that the present disclosure does not specifically limit the specific form of the back side 22 and / or the elastic component 3. The above situation is only an exemplary description of the forms in which the back side 22 and / or the elastic component 3 can exist, but is not limited to the situations described in the above embodiments.

[0067] In some embodiments, the elastic component 3 may include a support portion, and the support portion 27 may be connected to the key component 2 and / or the switch component 110. With this arrangement, the elastic component 3 may be connected to the key component 2 and / or the switch component 110 through the support portion, and may provide support for the deformation portion 31.

[0068] like Figure 3 and Figure 4 As shown, the support portion 27 can be connected to the key assembly 2. For example, the support portion 27 can be located at the edge of the elastic assembly 3. In a cross-sectional view along the thickness direction of the key structure 1, the support portion 27 can be located on one side or both sides of the deformation portion.

[0069] It is understandable that the support portion 27 can be connected to the key assembly 2 and / or the elastic assembly 3 by any of the following connection methods: for example, welding, bonding, threaded connection, mortise and tenon connection, etc., but the present disclosure does not specifically limit the types of the support portion and the key assembly 2 and / or the elastic assembly 3, that is, those skilled in the art can set or adjust according to actual conditions, as long as the support portion and the key assembly 2 and / or the elastic assembly 3 can be relatively fixed. The term "and / or" means that there are three situations. In the first situation, the support portion can be connected to the key assembly 2; in the second situation, the support portion can be connected to the elastic assembly 3; in the third situation, the support portion can be connected to the key assembly 2 and the elastic assembly 3.

[0070] In some embodiments, Figure 4 or Figure 5 As shown, the back surface 22 may include a recessed portion 41. For example, the back surface 22 may be recessed in a direction toward the pressing surface 21 to form the recessed portion 41. When the key assembly 2 applies a force to the elastic assembly 3, the elastic assembly 3 may deform toward the recessed portion 41. In the present disclosure, the provision of the recessed portion 41 provides a space for the elastic assembly 3 to deform.

[0071] In this embodiment, a recessed portion 41 is provided on the back side 22 so that a gap 4 can be formed between the recessed portion 41 and the deformation portion 31 of the elastic component 3, thereby simplifying the design of the gap 4 and eliminating the need for an additional gap structure, making the key structure 1 more compact and facilitating the miniaturization of the key structure 1.

[0072] It can be understood that the recessed portion 41 can be a portion recessed from the back side 22 toward the pressing surface 21. In the cross-section of the button assembly 2, the recessed portion 41 can be circular or rectangular, etc., but the present disclosure does not specifically limit the shape of the recessed portion 41, that is, those skilled in the art can set or adjust it according to actual conditions, as long as the gap 4 between the recessed portion 41 and the elastic assembly 3 can provide a deformation space for the deformation portion 31.

[0073] In some embodiments, Figure 4 or Figure 5 As shown, the elastic component 3 may further include a first elastic member 32, and the first elastic member 32 may be disposed on a first side of the elastic component 3. When the key assembly 2 applies a force to the elastic component 3, the first elastic member 32 may apply a force to the key assembly away from the switch assembly 110. That is, in the disclosure, the first elastic member 32 may have a deformation portion 31. The deformation portion 31 is located on the first elastic member 32, and can provide a restoring force when the first elastic member 32 is deformed. The restoring force acts on the key assembly 2, and can prevent the key assembly 2 from loosening.

[0074] Among them, the first elastic member 32 can be a metal dome, a spring, rubber, etc., but the present disclosure does not specifically limit the type of the first elastic member 32, that is, technical personnel in this field can set or adjust it according to actual conditions, as long as the first elastic member 32 can provide force to the button assembly 2 and has the ability of elastic deformation.

[0075] In some embodiments, Figure 3 or Figure 4 As shown, the elastic component 3 may further include a contact portion 33, which may be located at the second side of the elastic component 3. When the key component 2 applies a force to the elastic component 3, the contact portion 33 may contact the switch component 110. With this arrangement, after the key structure 1 receives the pressing force, the pressing force may be transmitted to the switch component 110 through the contact portion 33, so as to trigger the switch component 110 and turn the switch component 110 on or off.

[0076] In some embodiments, Figure 4 or Figure 5As shown, the elastic component 3 may also include a second elastic member 34, and the second elastic member 34 may be arranged on the contact portion 33. In the present disclosure, when the key assembly 2 applies a force to the elastic component 3, the side of the second elastic member 34 facing the switch assembly 110 may abut against the switch assembly. In the arrangement of the present disclosure, the second elastic member 34 may buffer the contact stress between the contact portion 33 and the switch assembly 110, and avoid excessive impact force between the contact portion 33 and the switch assembly 110. It is understandable that the second elastic member 34 may be a component for buffering the contact between the contact portion 33 and the switch assembly 110, and the second elastic member 34 may be rubber, silicone, polyurethane, foam or sponge, etc., but the present disclosure does not specifically limit the type of the second elastic member 34, that is, those skilled in the art may set or adjust according to actual conditions, as long as the second elastic member 34 can buffer the contact stress between the contact portion 33 and the switch assembly 110.

[0077] In some embodiments, Figure 4 or Figure 5 or Figure 6 As shown, the key assembly 2 may further include a key housing 24 and a bracket 25 arranged in a stacked manner, the pressing surface 21 may be located on a side of the key housing 24 away from the bracket 25, and the back surface 22 may be located on the bracket 25. In this embodiment, the key housing 24 may be regarded as a pressing component of the key assembly 2, the pressing surface 21 may be the top surface of the key housing 24, the bracket 25 may be regarded as a force conducting component of the key assembly 2, and the back surface 22 may be a side of the bracket 25 facing the switch assembly 110 of the electronic device 100.

[0078] In the present disclosure, the key assembly 2 is arranged on a side of the bracket 25 away from the key housing 24. When a force is applied to the key housing 24, the force can be transmitted from the key housing 24 to the key assembly 2 through the bracket 25. The key assembly 2 is arranged on the bracket 25, and the bracket 25 can be used to fix the key structure 1 on the electronic device.

[0079] like Figure 3 As shown, the bracket 25 may be provided with a limiting member 26, one end of which may be provided on a side of the bracket 25 facing the key housing 24, and the limiting member 26 is used to limit the movement of the bracket 25 in the thickness direction of the key structure 1. In the present disclosure, the thickness direction of the key structure 1 may be the direction from the first side of the elastic component to the second side, such as Figure 3 As shown, the thickness direction may be parallel to the first direction D1 and the second direction D2.

[0080] like Figure 3As shown, the other end of the limiter 26 has a height difference with the end connected to the bracket 25 in the thickness direction. When the key structure 1 is installed in an electronic device, the other end of the limiter 26 is connected to the main body of the electronic device. In some embodiments, taking the electronic device as a mobile phone as an example, the other end of the limiter 26 can be connected to the back shell of the mobile phone or the middle frame of the mobile phone. Since the other end of the limiter 26 has a height difference with the end connected to the bracket 25 in the thickness direction, it is possible to limit the movement of the bracket 26 in the thickness direction of the key structure 1.

[0081] In some embodiments, the key assembly 2 may further include a fingerprint module (not shown), which may be disposed in the key housing 24. By disposing the fingerprint module in the key housing 24, the key structure 1 may have a fingerprint recognition function, thereby improving the functional integration of the key structure 1.

[0082] In some embodiments, Figure 3 As shown, the key assembly 2 may further include a limiter 26, which may be disposed on the bracket 25, and the limiter 26 may be used to limit the relative distance between the key assembly 2 and the switch assembly 110. By providing the limiter 26, the key structure 1 and the electronic device 100 may be mutually limited, thereby realizing a movably connected key structure 1 and the switch assembly 110.

[0083] In some embodiments, when the key structure 1 is in a non-pressed state, the elastic component 3 may apply a reaction force to the switch component 110 . The reaction force may be smaller than the pressing force of pressing the switch component 110 .

[0084] In the present disclosure, when the key assembly 2 does not apply a force to the elastic assembly 3, the elastic assembly 3 generates a first deformation amount in a direction away from the key assembly 2. When the key assembly 2 applies a force to the elastic assembly 3, the elastic assembly 3 generates a second deformation amount in a direction close to the key assembly 2, and the first deformation amount is smaller than the second deformation amount.

[0085] In this embodiment, the elastic component 3 can exert force in two directions. Figure 3 As shown, in the first direction D1, the elastic component 3 applies a force to the key component 2, so that the key component 2 is away from the switch component 110. In the second direction D2, the elastic component 3 applies a reaction force to the switch component 110. The present disclosure can avoid mis-triggering the switch component 110 by setting the first deformation amount to be smaller than the second deformation amount.

[0086] In the present disclosure, since the first deformation amount is smaller than the second deformation amount, the reaction force in the embodiment can be smaller than the pressing force required to press the switch assembly 110. Through this arrangement, when the key structure 1 is not pressed, the elastic component 3 can both give the key an outward force to prevent it from loosening and slightly push the switch assembly 110 without triggering it. When the switch assembly 110 needs to be triggered, as long as the pressing force exceeds the reaction force, the key assembly 2 will continue to move and press the switch assembly 110 to achieve normal triggering. After releasing the key, the two forces of the elastic component 3 return the key structure 1 to a non-pressed state, waiting for the user to press the key structure 1 again.
