[0027] In the related art, when pressing a button on an electronic device, it is usually necessary to apply force to the central area of ​​the button to effectively trigger the key operation. However, when the key has a large pressing area, users may often press the button in the edge area away from the central area. When applying force to the edge area of ​​the key, this force is difficult to effectively trigger the key operation, resulting in poor key triggering effect and low key reliability.

[0028] Figure 1 This is an exploded view of one side of a key assembly provided in an embodiment of the present application. Figure 2 This is an exploded view of the other side of a key assembly provided in an embodiment of the present application. Figure 1 and Figure 2 The button assembly 000 may include: a surface shell 100, a bracket 200, an elastic member 300 and a circuit board 400.

[0029] The housing 100 in the key assembly 000 is connected to the bracket 200. The side of the housing 100 facing the bracket 200 may be provided with a pressing portion 101. The elastic member 300 in the key assembly 000 may be located between the housing 100 and the bracket 200. The elastic member 300 may include a supporting portion 301 and a positioning portion 302. Here, the positioning portion 302 may be connected to the supporting portion 301.

[0030] Figure 3 This is a schematic diagram of the structure of an elastic member provided in an embodiment of the present application. Figure 1 . refer to Figure 1 、 Figure 2 and Figure 3 The support portion 301 of the elastic member 300 may have a first surface S1 and a second surface S2 that are opposite to each other, and the first surface S1 of the support portion 301 is closer to the housing 100 than the second surface S2. That is, the first surface S1 of the support portion 301 may face the housing 100, and the second surface S2 of the support portion 301 may face the bracket 200. The positioning portion 302 of the elastic member 300 may have a positioning cavity K1. Figure 3 and Figure 4 , Figure 4 This is a cross-sectional view of a button assembly provided in an embodiment of the present application. The pressing portion 101 of the cover 100 can be at least partially accommodated in the positioning cavity K1 of the positioning portion 302.

[0031] The circuit board 400 in the key assembly 000 can be located on the side of the bracket 200 facing away from the housing 100, and a trigger key 401 can be provided on the side of the circuit board 400 facing the bracket 200. The portion of the positioning portion 302 protruding from the second surface S2 passes through the bracket 200 to contact the trigger key 401 of the circuit board 400.

[0032] It should be noted that the housing 100 may include a pressing surface 102 connected to the pressing portion 101. When a pressing force is applied to the pressing surface 102 of the housing 100, the pressing surface 102 of the housing 100 may partially deform, thereby causing the pressing portion 101 to move toward the circuit board 400. During this process, the pressing portion 101 may cause the positioning portion 302 to move toward the circuit board 400, causing the positioning portion 302 to press the trigger key 401 provided on the circuit board 400. In this way, after the trigger key 401 is pressed, the circuit board 400 can detect the key operation triggered by the trigger key 401.

[0033] In this embodiment, the positioning portion 302 not only has a portion protruding from the second surface S2 of the support portion 301, but also has a portion protruding from the first surface S1 of the support portion 301. The portion of the positioning portion 302 protruding from the first surface S1 can contact the side of the face shell 100 facing the bracket 200. For example, the portion of the positioning portion 302 protruding from the first surface S1 can contact the pressing surface 102 of the pressing portion 101 provided in the face shell 100. It should be noted that the elastic member 300 can be an elastic structure such as a spring or elastic rubber.

[0034] In this way, when the pressing surface 102 in the cover 100 is subjected to a pressing force, the pressing surface 102 can compress and deform the portion of the positioning portion 302 protruding from the first surface S1 of the support portion 301, thereby causing the portion of the positioning portion 302 protruding from the second surface S1 of the support portion 301 to press the trigger key 401. After the pressing force applied to the pressing surface 102 in the cover 100 is released, the portion of the positioning portion 302 protruding from the first surface S1 of the support portion 301 can return to its undeformed state, thereby causing the portion of the positioning portion 302 protruding from the second surface S1 of the support portion 301 to stop pressing the trigger key 401.

[0035] In the present application, since a pressing portion 101 is provided on the side of the face shell 100 facing the bracket 200, and at least a portion of the pressing portion 101 is accommodated in the positioning cavity K1 of the elastic member 300, when the user presses the face shell 100, the pressing portion 101 can directly act on the supporting portion 301 of the elastic member 300, thereby making the deformation of the elastic member 300 provide the user with clear and powerful feedback.

[0036] In this embodiment, the elastic member 300 not only has a supporting function, but also realizes stable positioning and guidance of the pressing portion 101 through the design of its positioning portion 302. For example, the positioning portion 302 is provided with a positioning cavity K1, which can ensure that the pressing portion 101 does not deviate from the predetermined path during the pressing process. At the same time, the portion of the positioning portion 302 protruding from the second surface K2 of the support portion 301 passes through the bracket 301 and forms an elastic contact with the trigger key 401 on the circuit board 400, thereby enhancing the stability and reliability of the key assembly 000. When the user presses the face shell 101, the deformation of the elastic member 300 will push the positioning portion 302 to contact the trigger key 401, thereby triggering the corresponding circuit signal, so that the trigger mechanism of the key assembly 000 is efficient and sensitive, and can quickly respond to the user's operating instructions.

[0037] like Figure 1 As shown, the surface of the housing 100 facing away from the bracket 200 has a larger area. Therefore, in some embodiments of the present application, the key assembly 100 can be a key with a larger key area. Here, the pressing portion 101 in the housing 100 is generally located in the central area of ​​the corresponding pressing surface 102. Since the portion of the positioning portion 302 protruding from the first surface S1 of the support portion 301 can be located toward the pressing surface 102 in the housing 100 and can contact the pressing surface 102, whenever the pressing surface 102 is deformed under pressure, the portion of the positioning portion 302 protruding from the first surface S1 of the support portion 301 is compressed and deformed. Therefore, whether pressing the central area of ​​the pressing surface 102 in the housing 100 or the edge area of ​​the pressing surface 102, the portion of the positioning portion 302 protruding from the first surface S1 of the support portion 301 can be compressed and deformed normally. In this way, the reliability of pressing the key assembly 000 to trigger a key operation can be effectively improved.

[0038] Figure 5 This is an exploded schematic diagram of another key assembly on one side of the embodiment of the present application. Figure 5 As shown, the side of the bracket 200 in the key assembly 000 facing the housing 100 may be provided with a mounting groove U. The support portion 301 may be at least partially accommodated in the mounting groove U of the bracket 100. After the support portion 301 is at least partially accommodated in the mounting groove U of the bracket 100, the second surface S2 of the support portion 301 may contact the bottom of the mounting groove U.

[0039] In the present application, the support portion 301 is at least partially accommodated in the mounting groove U, which can achieve a tight fit between the support portion 301 and the bracket 200, enhance the stability of the overall structure, and reduce vibration caused by loose components. The design of the mounting groove U provides clear positioning and guidance for the installation of the support portion 301.

[0040] like Figure 5As shown, the side of the bracket 200 in the key assembly 000 facing the housing 100 may further be provided with a positioning hole V, which may be in communication with the mounting groove U. Thus, after the support portion 301 is at least partially accommodated in the mounting groove U of the bracket 100, the portion of the positioning portion 302 in the elastic member 300 protruding from the second surface S2 passes through the positioning hole V to contact the trigger key 401 on the circuit board 400.

[0041] In this application, the coordination of the positioning hole V and the positioning portion 302 ensures precise alignment between the bracket 200 and the trigger key 401. The positioning portion 302 passes through the positioning hole V and forms elastic contact with the trigger key 401, providing a certain resistance feedback when the trigger key 401 is pressed, thus providing a good tactile feel. The coordinated design of the positioning hole V and the positioning portion 302 helps to disperse stress during key operation.

[0042] In addition, by providing a mounting groove U on the bracket 200, the support portion 301 in the elastic member 300 can be hidden, so that after the portion of the positioning portion 302 protruding from the first surface S1 contacts the side of the face shell 100 facing the bracket 200, the portion of the positioning portion 302 protruding from the first surface S1 can be compressed and deformed more stably.

[0043] It should be noted that the key assembly 000 in this application can be used in both single-key and multi-key scenarios. Here, the application of the key assembly 000 in a single-key scenario means that the key assembly 000 is provided with only one pressing portion 101, one positioning portion 302, and one trigger key 401. The application of the key assembly 000 in a multi-key scenario means that the key assembly 000 is provided with multiple pressing portions 101, multiple positioning portions 302, and multiple trigger keys 401.

[0044] Figure 6 This is an exploded schematic diagram of another key assembly on the other side of an embodiment of the present application. Figure 7 This is a schematic diagram of the structure of another elastic member provided in an embodiment of the present application. Figure 5 、 Figure 6 and Figure 7 The side of the housing 100 in the key assembly 000 facing the bracket 200 may be provided with multiple pressing portions 101. Here, the housing 100 may include multiple pressing surfaces 102, each of which may correspond to the multiple pressing portions 101 one by one, and each pressing portion 101 may be provided in the central area of ​​the corresponding pressing surface 102.

[0045] In this embodiment, the elastic member 200 in the key assembly 000 may include multiple positioning portions 302. In the elastic member 200, each positioning portion 302 may be connected to the support portion 301. The multiple positioning portions 302 in the elastic member 200 may correspond one-to-one with the multiple pressing portions 101 in the housing 100. The mating relationship between each pressing portion 101 and the positioning portion 302 can be referenced to the content in the previous embodiment and will not be further described here.

[0046] In this embodiment, a plurality of trigger keys 401 may be provided on the side of the circuit board 400 facing the bracket 200. The plurality of trigger keys 401 may correspond one-to-one with the plurality of positioning portions 302. The coordination relationship between each trigger key 401 and the positioning portion 302 can be referred to in the previous embodiment and will not be further described here.

[0047] In this embodiment, the housing 100 may be provided with two pressing portions 101. Accordingly, the housing 101 may include two pressing surfaces 102 connected to the two pressing portions 101 in a one-to-one correspondence, the elastic member 200 may include two positioning portions 302 corresponding to the two pressing portions 101 in a one-to-one correspondence, and the side of the circuit board 400 facing the bracket 100 may be provided with two trigger keys 401 corresponding to the two positioning portions 302 in a one-to-one correspondence.

[0048] Here, after applying pressing force to a pressing surface 102 in the face shell 100, the pressing surface 102 can be locally deformed to drive the corresponding pressing portion 101 to move in the direction toward the circuit board 400, and then drive the corresponding positioning portion 302 to move in the direction toward the circuit board 400 to press the corresponding trigger key 401.

[0049] In the present application, due to the presence of multiple pressing portions 101 and positioning portions 302, different functions or operations can be triggered by pressing different locations on the cover 100. When multiple pressing portions 302 are simultaneously subjected to pressure, each corresponding to a positioning portion 302, it can ensure that the elastic member 300 is subjected to uniformly distributed force, thereby improving the durability and reliability of the key assembly 000.

[0050] It should be noted that the support portion 301 and the plurality of positioning portions 302 in the elastic member 300 can be an integral structure. For example, the elastic member 300 can be formed using an integral molding process using a material having elasticity. Here, the support portion 301 and the plurality of positioning portions 302 in the elastic member 300 are both thin layer structures at various locations. This allows the portion of each positioning portion 302 that protrudes outward from the first surface S1 of the support portion 301 to better undergo compression deformation and rebound restoration.

[0051] In this embodiment, in order to improve the structural strength of the positioning portion 302 in the elastic member 300 , a buffer portion 303 may be provided on the first surface S1 of the supporting portion 301 in the elastic member 300 .

[0052] In this embodiment, the elastic member 300 in the key assembly 000 may further include: a plurality of buffer portions 303, each of which may be located on the first surface S1 of the support portion 301. Here, in the elastic member 300, the two positioning portions 302 may be arranged alternately with the two buffer portions 303. That is, in the elastic member 300, two oppositely disposed buffer portions 303 may be distributed between two adjacent positioning portions 302, and the arrangement direction of the two oppositely disposed buffer portions 303 may intersect with the arrangement direction of the two oppositely disposed buffer portions 303. For example, the arrangement direction of the two positioning portions 302 may be perpendicular to the arrangement direction of the two oppositely disposed buffer portions 303. The plurality of buffer portions 303 in the elastic member 300 may also be integrally formed with the support portion 301 and the plurality of positioning portions 302. In the elastic member 300, the portion of the positioning portion 302 protruding from the first surface S1 of the support portion 301 may be connected to the buffer portion 303 located on the first surface S1.

[0053] In this application, the buffering portion effectively absorbs the impact force generated when a user presses the cover. When multiple buffering portions are staggered with the positioning portions, the pressure is more evenly distributed, making the pressing process smoother and gentler, and enhancing the overall structural strength of the elastic member. The positioning portion ensures that the key is pressed in the correct direction, while the buffering portion provides additional support and stability. Together, they reduce any wobble or shifting of the key during pressing.

[0054] In this embodiment, the side of the positioning portion 302 facing the housing 100 can be flush with the side of the buffer portion 303 facing the housing 100. That is, the side of the buffer portion 303 facing the housing 100 can also contact the side of the housing 100 facing the bracket 200.

[0055] In this case, by providing a buffer portion 303 in the elastic member 300, the portion of the positioning portion 302 protruding from the first surface S1 and the side of the buffer portion 303 facing the face shell 100 can both contact the side of the face shell 100 facing the bracket 200, thereby increasing the contact area between the elastic member 300 and the side of the face shell 100 facing the bracket 200, so that the structural strength of the positioning portion 302 in the elastic member 300 is higher, which can be more conducive to the stable compression deformation and rebound restoration of the portion of the positioning portion 302 protruding from the first surface S1.

[0056] In the present application, when the positioning portion 302 and the buffer portion 303 are flush with the side of the face shell 100, the user will not experience additional resistance or a sense of jamming due to the unevenness between the components when pressing the face shell 100, thereby reducing stress concentration points caused by height differences between the components and reducing the risk of damage due to long-term use or external force.

[0057] In this embodiment, in the elastic member 300, the two positioning portions 302 and the two buffer portions 303 enclose a cavity K2. Here, in the elastic member 300, the two adjacent positioning portions 302 and the two oppositely disposed buffer portions 303 can enclose the cavity K2. An exhaust channel L communicating with the cavity K2 can be provided between the positioning portions 302 and the buffer portion 202. Here, an exhaust channel L can be provided between the portion of the positioning portion 302 protruding from the first surface S1 and the buffer portion 202.

[0058] In this case, since the sides of the positioning portion 302 and the buffer portion 303 in the elastic member 300 facing the face shell 100 will both contact the side of the face shell 100 facing the bracket 200, the cavity K2 enclosed by the two positioning portions 302 and the two oppositely arranged buffer portions 303 may be sealed by the face shell 100. After the cavity K2 is sealed by the face shell 100, the compression deformation of the portion of the positioning portion 302 protruding from the first surface S1 may be affected. To this end, an exhaust channel L connected to the cavity K2 can be provided between the portion of the positioning portion 302 protruding from the first surface S1 and the buffer portion 202, so that the cavity K2 is connected to the external environment through the exhaust channel L, thereby ensuring that the face shell 100 will no longer seal the cavity K2. In this way, it can be ensured that the portion of the positioning portion 302 protruding from the first surface S1 can be compressed and deformed more smoothly.

[0059] In this application, the presence of cavity K2 provides a compressible space for key assembly 000. When the housing 100 is pressed by an external force, the air within cavity K2 can flow through the exhaust channel L, thereby achieving pressure balance. This reduces the impact force and vibration generated during the pressing process and improves the cushioning effect of key assembly 000. After the external force is released, the presence of the exhaust channel L allows the housing 100 to return to its original state more quickly.

[0060] For example, an exhaust channel L is formed between the buffer member 303 and the adjacent positioning portion 302. This exhaust channel L connects the cavity K1 enclosed by the positioning portion 302 and the buffer member 303 to the outside world. During the pressing and rebounding process of the cover 100, the exhaust channel L balances the air pressure between the cavity and the outside world, reducing the sticky feeling of the key. When any pressing portion 101 is pressed, the pressure applied to the pressing portion 101 is relatively evenly distributed to the elastic member 300, thereby enhancing the reliability of key triggering operations across the entire surface of the cover 100.

[0061] like Figure 5 and Figure 6 As shown, a snap-fitting member 103 is provided on the side of the face shell 100 facing the bracket 200. A snap-fitting groove 201 is provided on the side of the bracket 200 facing the face shell 100. The snap-fitting member 103 can be snap-fitted with the snap-fitting groove 201. After the snap-fitting member 103 is snap-fitted with the snap-fitting groove 201, the face shell 100 can be connected to the bracket 200. With respect to the elastic member 300 located between the face shell 100 and the bracket 200, the supporting portion 301 in the elastic member 300 is distributed in the mounting groove U provided on the side of the bracket 200 facing the face shell 100. The portion of the positioning portion 302 protruding from the first surface S1 and the buffer layer 303 are both in contact with the side of the face shell 100 facing the bracket 200. Furthermore, the pressing portion 101 provided on the face shell 100 is distributed in the positioning cavity K1 of the positioning portion 302.

[0062] It should be noted that the embodiment of the present application is schematically described by taking as an example an example where the side of the face shell 100 facing the bracket 200 is provided with the snap-fitting member 103, and the side of the bracket 200 facing the face shell 100 is provided with the snap-fitting slot 201. In other possible implementations, the side of the bracket 200 facing the face shell 100 may also be provided with the snap-fitting member 103, and the side of the bracket 200 facing the face shell 100 may also be provided with the snap-fitting slot 201, and the effect of connecting the face shell 100 and the bracket 200 may also be achieved. The embodiment of the present application is not limited to this.

[0063] In the present application, a secure connection between the face shell 100 and the bracket 200 is ensured by the snap-fit ​​design of the snap-fit ​​member 103 and the snap-fit ​​groove 201. When the face shell 100 is pressed by an external force, the elastic member 300 between the face shell 100 and the bracket 200 undergoes elastic deformation. After the external force is released, the presence of the elastic member 300 causes the snap-fit ​​member 103 on the face shell to move to its initial position. During the pressing and rebounding process of the face shell 100, the snap-fit ​​groove 201 on the bracket 200 limits the snap-fit ​​member 103 on the face shell 100.

[0064] In addition, in order to ensure that the circuit board 400 in the key assembly 000 is not easily corroded by water vapor invading from the outside after the key assembly 000 is subsequently assembled into the shell of the electronic device, the snap-in groove 201 provided on the bracket 200 can be sealed.

[0065] In this embodiment, the key assembly 000 may further include: a plurality of sealing gaskets 500 corresponding one-to-one to the plurality of snap-in grooves 201. Each sealing gasket 500 may be located on the side of the bracket 200 facing away from the housing 100, and each sealing gasket 500 may cover the snap-in groove 201 on the side of the bracket 200 facing away from the housing 100. Here, in the case where the snap-in groove 201 is a snap-in groove, each sealing gasket 500 may be distributed and arranged in a corresponding snap-in groove on the side of the bracket 200 facing away from the housing 100. In this way, the snap-in groove 201 provided on the bracket 200 can be sealed by the sealing gasket 500.
