Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification does not necessarily mean the same embodiment.

[0026] In a first aspect, Fig. 1 is a structural schematic view of a key assembly provided by the embodiment of the present application, Fig. 2 is an exploded view of the key assembly provided by the embodiment of the present application, Fig. 3 is a structural schematic view of another key assembly provided by the embodiment of the present application, as Figs. 1 to 3 The embodiment of the present application provides a key assembly, and the key assembly comprises:

[0027] The key main body 1 comprises a pressing surface 11 and a bearing surface 12 arranged oppositely.

[0028] The pressing piece 2 is arranged on the bearing surface 12, and the pressing piece 2 and the key main body 1 are integrally formed. At least part of the pressing piece 2 is deformable, so that when the pressing surface 11 is pressed, at least part of the pressing piece 2 is deformed.

[0029] As can be seen from the above embodiments, in the embodiments of the present application, since the pressing piece 2 is arranged on the bearing surface 12, and the pressing piece 2 and the key body 1 are integrally formed, at least part of the pressing piece 2 is deformable, so that when the pressing surface 11 is pressed, at least part of the pressing piece 2 deforms, thus, while meeting the pressing feeling of the key assembly through the deformation of the pressing piece 2, the pressing piece 2 and the key body 1 are integrally formed, the assembly process of the key assembly is reduced, the labor cost is reduced, and the loss of the pressing piece 2 in the production process of the key assembly can be avoided, so as to improve the yield of the key assembly.

[0030] In the above embodiments, the key body 1 can be any one of a rectangular plate structure, an elliptical plate structure, a polygonal plate structure, etc., which is not limited in the embodiments of the present application. The key body 1 can include the pressing surface 11 and the bearing surface 12 arranged oppositely, the pressing surface 11 can be a curved surface or a plane, and the pressing surface 11 is mainly used to provide a stable pressing area for the user. The bearing surface 12 can be a curved surface or a plane, which is not limited in the embodiments of the present application. In some embodiments, the pressing surface 11 and the bearing surface 12 are two surfaces with larger areas among the outer surfaces of the key body 1 arranged oppositely, so as to provide larger pressing surface 11 and bearing area.

[0031] The pressing piece 2 can be a protruding structure arranged on the bearing surface 12, which can be any one of a cylindrical structure, a prism structure, etc., or the pressing piece 2 can be a frame structure with a deformation space arranged on the bearing surface 12, which is not limited in the embodiments of the present application. The integrally formed manner of the pressing piece 2 and the key body 1 can be any one of insert injection molding, double-color injection molding, secondary injection molding, or thermoplastic forming, so that the pressing piece 2 and the key body 1 form an integral whole without the need for assembly through other processes, thereby reducing the assembly process of the key assembly, and avoiding the loss of the pressing piece 2 and the key body 1 in the assembly process.

[0032] To meet the pressing feeling of the key assembly, the pressing feeling of the key assembly can be understood as the indirect force applied by the key body 1 to the pressing piece when the key body 1 is subjected to an external force, so that the elastic force or the deformation force of the at least partially deformed pressing piece 2. Based on this, in the embodiments of the present application, at least part of the pressing piece 2 is deformable, which can be understood as that at least part of the pressing piece 2 has a deformable structure, which can be a deformable structure formed of a flexible material, such as a rubber material, an elastomer plastic, an elastic foam material, etc., or a structure with a bending deformation space, such as an arm-shaped structure with a certain distance from the bearing surface 12, or a shell structure with a deformation space, which is not limited in the embodiments of the present application.

[0033] It should be noted that the pressing piece 2 can be deformed in the direction close to the pressing surface 11, that is, after the pressing surface 11 is subjected to an external force, the piece in contact with the end of the pressing piece 2 applies a support force to the pressing piece 2 in the opposite direction, so that the pressing piece 2 is deformed in the direction close to the pressing surface 11. The pressing piece 2 can also be deformed in the circumferential direction, that is, after the pressable surface 11 is subjected to an external force, the external force is not a force perpendicular to the plane where the pressable surface 11 is located (it can be understood that the pressable surface 11 is subjected to a force obliquely), then the piece in contact with the end of the pressing piece 2 applies a support force to the pressing piece 2 in the first direction, the first direction is any direction in the circumferential direction of the pressing piece 2, thereby making the pressing piece 2 deform in any direction in the circumferential direction, or the pressing piece 2 can also deform in other directions, the specific deformation direction is determined according to the force condition of the key body 1, and the embodiments of the present application do not limit this.

[0034] In some embodiments, the pressing piece 2 comprises a deformable flexible block 21, and the flexible block 21 is integrally formed with the key body 1.

[0035] In this embodiment, the flexible block 21 can be a convex structure protruding from the bearing surface 12, and the flexible block 21 can be any one of a rectangular plate structure, an elliptical plate structure, a polygonal plate structure and the like, and the embodiments of the present application do not limit this. In this way, since the flexible block 21 is integrally formed with the key body 1, the flexible block 21 and the key body 1 can form an integrated structure, and the flexible block 21 can be avoided to be installed on the key body 1 by other means, and the loss of the flexible block 21 in the assembly process can be avoided. In addition, the flexible block 21 can be a block-shaped convex structure composed of rubber material, elastic plastic, elastic foam material and the like, so that the flexible block 21 can have a certain elasticity, and the pressing feeling of the key body 1 as a whole can be improved by the flexible block 21.

[0036] In some embodiments, the key body 1 further comprises a containing piece 13 for containing the flexible block 21, and the containing piece 12 is protruded from the bearing surface 11, and part of the flexible block 21 is protruded from the containing piece 13.

[0037] In this embodiment, the containing piece 13 can be a structure with a certain cavity, such as a cylinder structure, a box structure, a shell structure and the like, so that the containing piece 13 can be arranged around the circumferential side of the flexible block 21, and the flexible block 21 is at least partially protruded from the containing piece 13. In this way, by the containing piece 13, the injection molding of the flexible block 21 is facilitated, and the strength of the key body 1 as a whole can be improved by the containing piece 13.

[0038] In some embodiments, the accommodating member 13 has an accommodating cavity 131, and a first opening 132 and a second opening 133 in communication with the accommodating cavity 131 respectively, the first opening 132 is arranged away from the pressing surface 11, a part of the flexible block 21 protrudes from the accommodating member 13 through the first opening 132, the second opening 133 extends in a direction away from the pressing surface 11, the accommodating member 13 and the flexible block 21 are injection molded in two colors, and the second opening 133 is a feeding port for injection molding of the flexible block 21.

[0039] In this embodiment, the accommodating member 13 and the flexible block 21 are injection molded in two colors, which facilitates the molding and processing of the flexible block 21 and helps to improve the manufacturing efficiency of the key assembly. It should be noted that two-color injection molding refers to injection molding of two different materials into the same mold, so that the molded part is formed by two materials. Therefore, when the accommodating member 13 and the flexible block 21 are injection molded in two colors, the accommodating member 13 and the flexible block 21 can be integrally formed in different material states, for example, the accommodating member 13 and the key body 1 are made of hard glue, and the flexible block 21 is made of soft glue.

[0040] In addition, since the second opening 133 extends in a direction away from the pressing surface 11, the accommodating member 13 and the flexible block 21 are injection molded in two colors, and the second opening 133 is a feeding port for injection molding of the flexible block 21, the injection molding material of the flexible block 21 can be injected into the accommodating cavity 131 through the second opening 133, which facilitates the injection molding of the flexible block 21. At the same time, since the first opening 132 is arranged away from the pressing surface 11, a part of the flexible block 21 protrudes from the accommodating member 13 through the first opening 132, so that the arrangement of the accommodating member 13 does not affect the contact between the flexible block 21 and other components, and at the same time, the deformation of the flexible block 21 can be ensured.

[0041] In some embodiments, the pressing member 2 includes a base 23 and a cantilever 22 connected to the base 23, the base 23 is arranged on the bearing surface 12, the base 23, the cantilever 22 and the key body 1 are integrally formed, and when the pressing surface 1 is pressed, the cantilever 22 deforms towards the bearing surface 11.

[0042] In the embodiment, since the abutting member 2 comprises the base body 23 and the cantilever 22 connected with the base body 23, the base body 23 is arranged on the bearing surface 12, and the base body 23, the cantilever 22 and the key body 1 are integrally formed, thus the assembly process of the abutting member 2 can be reduced, the labor cost is lowered, and the formation of the abutting member 2 is facilitated. In addition, since the cantilever 22 deforms towards the bearing surface 11 when the pressing surface 1 is pressed, the cantilever 22 can deform towards the bearing surface 11 when the abutting member 2 is subjected to an external force. In summary, in the embodiment, the pressing feeling of the key assembly can be ensured by the deformation of the cantilever 22, and the base body 23, the cantilever 22 and the key body 1 are integrally formed, thus the cantilever 22 can be avoided to be installed on the key body 1 by other means, and the loss of the cantilever 22 in the assembly process can be avoided.

[0043] In some embodiments, the base body 23 comprises a first bearing portion 231 and a second bearing portion 232 arranged oppositely, and two ends of the cantilever 22 are connected with the first bearing portion 231 and the second bearing portion 232 respectively.

[0044] In the embodiment, since the two ends of the cantilever 22 are connected with the first bearing portion 231 and the second bearing portion 232 respectively, the connection between the cantilever 22 and the base body 23 can be ensured by the first bearing portion 231 and the second bearing portion 232, and the cantilever 22 can deform towards the bearing surface 11. In addition, it should be noted that the first bearing portion 231 and the second bearing portion 232 can each comprise an elastic deformation structure, which can be at least one of a U-shaped bending structure, an arch-shaped plate structure and an M-shaped bending structure, thus the deformation ability of the key assembly as a whole can be further improved by the elastic deformation structure comprised by the first bearing portion 231 and the second bearing portion 232, and the pressing feeling of the key assembly as a whole can be further improved. Meanwhile, buckles can be arranged at the edge positions of the first bearing portion 231 and the second bearing portion 232, so as to facilitate the assembly of the key assembly and other components.

[0045] In some embodiments, the cantilever 22 comprises a contact portion 221, a first connecting portion 222 and a second connecting portion 223, the first bearing portion 231, the first connecting portion 222, the contact portion 221, the second connecting portion 223 and the second bearing portion 232 are connected in sequence, and the width of the contact portion 221 is greater than the widths of the first connecting portion 222 and the second connecting portion 223.

[0046] In this embodiment, since the cantilever 22 comprises the contact portion 221, the first connecting portion 222 and the second connecting portion 223, the first bearing portion 231, the first connecting portion 222, the contact portion 221, the second connecting portion 223 and the second bearing portion 232 are sequentially connected, and the width of the contact portion 221 is greater than the width of the first connecting portion 222 and the second connecting portion 223, so that a larger contact area can be provided by the contact portion 221, which is beneficial to ensure the contact area between the cantilever 22 and other components and ensure the pressing contact effect of the key assembly. It should be noted that the contact portion 221 can be a circular plate-shaped structure located between the first connecting portion 222 and the second connecting portion 223, or the contact portion 221 can be a square plate-shaped structure located between the first connecting portion 222 and the second connecting portion 223, or the contact portion 221 can be a polygonal plate-shaped structure located between the first connecting portion 222 and the second connecting portion 223, and the embodiments of the present application do not limit this. The width of the first connecting portion 222 and the second connecting portion 223 can be understood as the size of the first connecting portion 222 and the second connecting portion 223 in the extension direction of the pressing body 1, and the width of the contact portion 221 can be understood as the size of the contact portion 221 in the extension direction of the pressing body 1.

[0047] In some embodiments, the first connecting portion 222 and the second connecting portion 223 each comprise a bending structure, and the first connecting portion 222 and the second connecting portion 223 are centrally symmetrical.

[0048] In this embodiment, the bending structure can be a bending structure with an included angle formed by two plate-shaped structures with different extension directions, or the bending structure 221 can be a wave-shaped plate-shaped structure, or the bending structure 221 can be an S-shaped plate-shaped structure, or a plate-shaped structure with an arc-shaped corner, or other structures with a bending included angle, and the embodiments of the present application do not limit this. For example, taking the bending structure with an included angle formed by two plate-shaped structures with different extension directions as an example, the first connecting portion 222 and the second connecting portion 223 each can comprise a first pressing plate and a second pressing plate, the end of the first pressing plate and the end of the second pressing plate are connected, and the extension direction of the first pressing plate and the extension direction of the second pressing plate intersect, so that the bending included angle is formed between the first pressing plate and the second pressing plate. In this way, the first connecting portion 222 and the second connecting portion 223 each comprise a bending structure, so that the deformation ability of the cantilever 22 as a whole can be improved by the bending structure comprised by the first connecting portion 222 and the second connecting portion 223, and the elastic recovery ability of the cantilever 22 can be improved by the bending structure. Since the first connecting portion 222 and the second connecting portion 223 are centrally symmetrical, the structure of the cantilever 22 can be simplified, the molding of the cantilever 22 is facilitated, and the cantilever 22 can be dispersed to the first connecting portion 222 and the second connecting portion 223 along the central symmetry point when subjected to force.

[0049] In some embodiments, there is a gap between the cantilever 22 and the bearing surface 12 in a first direction, and the first direction intersects with the plane in which the bearing surface 12 is located.

[0050] In this embodiment, since there is a gap between the cantilever 22 and the bearing surface 12 in the first direction, and the first direction intersects with the plane where the bearing surface 12 is located, the gap between the cantilever 22 and the bearing surface 12 in the first direction can provide sufficient deformation space for the deformation of the cantilever 22, which is beneficial to enhancing the overall deformation capability of the pressing member 2.

[0051] As can be seen from the above embodiments, in this embodiment, since the pressing member 2 is disposed on the bearing surface 12 and the pressing member 2 and the button body 1 are integrally formed, at least part of the pressing member 2 is deformable so that when the pressing surface 11 is pressed, at least part of the pressing member 2 deforms. Therefore, while satisfying the pressing feel of the button assembly through the deformation of the pressing member 2, the pressing member 2 and the button body 1 are integrally formed, reducing the assembly process of the button assembly, reducing labor costs, and avoiding the loss of the pressing member 2 during the production process of the button assembly, thereby improving the yield rate of the button assembly.

[0052] Secondly, embodiments of this application also provide an electronic device, which includes the button assembly described in any embodiment of the first aspect.

[0053] It should be noted that the electronic device can be a smart writing device, such as an electronic pen, or a smart wearable device, such as a smartwatch, or other devices with button components. This application does not limit the specific device to this type. Thus, in an electronic device including the button component described in any embodiment of the first aspect, since the pressing member 2 and the button body 1 are integrally formed, the assembly process of the button component can be reduced, labor costs can be lowered, and the loss of the pressing member 2 during the production process can be avoided, thereby improving the yield rate of the button component. Therefore, the manufacturing cost and efficiency of the electronic device can also be improved.
