As shown in fig. 6, considering that the key 12 moves toward the inside of the housing 11 under an external force, the pressing portion 121 of the key 12 presses the main body portion 131 attached to the pressing portion, the main body portion 131 generates elastic deformation and presses the flange portion 132 connected to the main body portion 131, so that the flange portion 132 generates elastic deformation, and in order to enable the flange portion 132 to generate elastic deformation better under the action of the pressing force, the first through hole 1311 has a central axis 13111, and a cross section of the plane where the flange portion 132 passes through the central axis 13111 has an inner edge 1321 close to the central axis 13111 and an outer edge 1322 far from the central axis 13111, wherein the inner edge 1321 has a first end 1321a and a second end 1321b located on the same side of the central axis 13111, and a first connection 1321c between the first end 1321a and the second end 1321b forms an included angle with the central axis 13111; and/or, outer edge 1322 has a third end 1322a and a fourth end 1322b that are on the same side of central axis 13111, and a second connection 1322c between third end 1322a and fourth end 1322b is angled with respect to central axis 13111. In this design, first line 1321c and/or second line 1322c are the contained angle setting with axis 13111, so flange portion 132 is whole to axis 13111 slope, also flange portion 132 is the cone, through designing flange portion 132 into the cone, make flange portion 132 can be better under the effect of extrusion's production elastic deformation, so after the external force cancellation at button 12, the resilience of button 12 except the resilience that relies on the button 12 switch, the resilience that produces when the flange portion 132 of elastic component 13 resumes deformation also can assist button 12 to kick-back, so can effectively reduce the phenomenon that button 12 kick-backs not in place appears, thereby effectively promote the pressing of button 12 and feel.

The first end 1321a and the second end 1321b are two arbitrary points on the inner edge 1321, for example, the first end 1321a may be an end of the inner edge 1321 near the main body 131, and the second end 1321b may correspond to an end of the inner edge 1321 far from the main body 131, so that the first end 1321c may be understood as a connection line between two ends of the inner edge 1321; of course, the first end 1321a may be located at a point on the inner edge line 1321 adjacent to the body portion 131, and the second end 1321b may be located at a point on the inner edge line 1321 distant from the body portion 131, so the first end 1321c may be a connection line between two points that are located between two ends of the inner edge line 1321 and distant from each other.

Similarly, the third end 1322a and the fourth end 1322b are two arbitrary points on the outer edge 1322, for example, the third end 1322a may be an end of the outer edge 1322 on the side close to the main body 131, and the fourth end 1322b may correspond to an end of the outer edge 1322 on the side far from the main body 131, so that the second connection 1322c may correspond to a connection line between two ends of the outer edge 1322; of course, the third end 1322a may be located at a point on the outer edge line 1322 adjacent to the body 131, and the fourth end 1322b may be located at a point on the outer edge line 1322 away from the body 131, so that the second connection 1322c may be a connection between two points that are located between two end points of the outer edge line 1322 and are away from each other. It is understood that the third end 1322a and the fourth end 1322b are two arbitrary points on the outer edge 1322, and a connection line between the third end 1322a and the fourth end 1322b (i.e., the second connection 1322c) is disposed at an angle with respect to the central axis 13111, i.e., the outer edge 1322 is entirely inclined with respect to the central axis 13111.

The inclination directions of the first line segment 13212 and the second line segment 13213 compared to the central axis 13111 can be, but are not limited to, the following embodiments.

As shown in fig. 7, in the first embodiment, along a direction perpendicular to the central axis 13111, the first line segment 13212 is gradually increased in distance from the end far from the second line segment 13213 to the end connected to the second line segment 13213, at least a portion of the first line segment 13212 is gradually increased in distance from the central axis 13111, the second line segment 13213 is gradually decreased in distance from the end connected to the first line segment 13212 to the end far from the first line segment 13212, that is, the inclination direction of the first line segment 13212 relative to the central axis 13111 is opposite to the inclination direction of the second line segment 13213 relative to the central axis 13111. Where "at least partially" should be understood to mean any sub-line segment contained within the enclosed space of the first line segment 13212. For example, the first line 13212 may be a semicircular arc line segment located on a side of the first connection line 1321c away from the central axis 13111, and the semicircular arc line segment includes a quarter circular arc line segment close to the main body 131 and a quarter circular arc line segment away from the main body 131, wherein, along a direction perpendicular to the central axis 13111, a distance between the quarter circular arc line segment close to the main body 131 and the central axis 13111 gradually increases, and a distance between the quarter circular arc line segment away from the main body 131 and the central axis 13111 gradually decreases. Similarly, the second line 13213 may also be a semicircular arc line, the semicircular arc line is located on one side of the first line 1321c close to the central axis 13111, and the semicircular arc line includes a quarter circular arc line close to the main body 131 and a quarter circular arc line far from the main body 131, wherein, in the direction perpendicular to the central axis 13111, the distance between the quarter circular arc line close to the main body 131 and the central axis 13111 is gradually reduced, and the distance between the quarter circular arc line far from the main body 131 and the central axis 13111 is gradually increased.

As shown in fig. 8, in the second embodiment, along a direction perpendicular to the central axis 13111, the first line segment 13212 is gradually increased in distance from the end far away from the second line segment 13213 to the end connected to the second line segment 13213, at least a portion of the first line segment 13212 is gradually increased in distance from the central axis 13111, the second line segment 13213 is gradually increased in distance from the end connected to the first line segment 13212 to the end far away from the first line segment 13212, and the distance between at least a portion of the second line segment 13213 and the central axis 13111 is gradually increased, that is, the inclination direction of the first line segment 13212 compared to the central axis 13111 is the same as the inclination direction of the second line segment 13213 compared to the central axis 13111. For example, the first line 13212 can be a sixth arc line located on a side of the first connection line 1321c away from the central axis 13111, and the distance between the sixth arc line and the central axis 13111 is gradually increased along a direction perpendicular to the central axis 13111. The second line 13213 may be a one-sixth arc line located on a side of the first line 1321c close to the central axis 13111, and the distance between the one-sixth arc line and the central axis 13111 is gradually increased along a direction perpendicular to the central axis 13111.

As shown in fig. 9, considering that the line shape of the first line segment 13212 may be a straight line or a curved line, and similarly, the line shape of the second line segment 13213 may be a straight line or a curved line, for example, the curved line may be a parabola, and in order to reduce the processing difficulty of the flange portion 132, it is further designed that the first line segment 13212 is one of a straight line segment and an arc line segment; and/or the second line segment 13213 is one of a straight line segment or a circular arc segment.

Specifically, the line type combination of the first line segment 13212 and the second line segment 13213 may be, but not limited to, the following several possible embodiments.

For example, as shown in fig. 9 (a), in one embodiment, the first line segment 13212 is a straight line segment and the second line segment 13213 is a straight line segment. The inclination angle (i.e., the first slope) of the first line 13212 with respect to the central axis 13111 may be the same as or different from the inclination angle (i.e., the second slope) of the second line 13213 with respect to the central axis 13111.

For example, as shown in fig. 9 (b), in one embodiment, the first line segment 13212 is a straight line segment and the second line segment 13213 is an arc line segment.

For example, in one embodiment, the first line segment 13212 is a circular arc line segment and the second line segment 13213 is a straight line segment.

For example, in one embodiment, the first line segment 13212 is a circular arc line segment and the second line segment 13213 is a circular arc line segment. The arc radius of the first line 13212 may be the same as or different from the arc radius of the second line 13213.

It should be noted that the inclination direction of the outer edge line 1322 with respect to the central axis 13111 may be the same as the inclination direction of the inner edge line 1321 with respect to the central axis 13111, and the specific line type of the outer edge line 1322 may also be the same as the specific line type of the inner edge line 1321, so that no further description is provided herein.

As shown in fig. 6, it can be understood that the smaller the thickness dimension of the flange portion 132, the more easily the flange portion 132 is elastically deformed by the pressing force of the main body portion 131, and the greater the amount of the elastic deformation, considering that the flange portion 132 still has a certain structural strength to support the main body portion 131, it is further designed that the distance between the inner edge line 1321 and the outer edge line 1322 in the direction perpendicular to the central axis 13111 is a, and a satisfies the conditional expression: a is more than or equal to 0.15 mm and less than or equal to 0.20 mm. Specifically, a may be, but not limited to, 0.15 mm, 0.18 mm, 0.20 mm, or the like. In the design, when a is more than or equal to 0.15 mm and less than or equal to 0.20 mm, the thickness of the flange part 132 is reasonably designed, so that the flange part 132 has good elastic flexibility under the action of the extrusion force of the main body part 131, and meanwhile, the flange part 132 also has good structural strength to support the main body part 131; when a is less than or equal to 0.15 mm, the flange portion 132 has strong elastic flexibility but weak structural strength; when a is 0.20 mm or more, the flange 132 has a strong structural strength but a weak elastic stretchability.

As shown in fig. 6, it is understood that the inclination of the entire flange portion 132 intersecting the central axis 13111 determines the degree of difficulty of the flange portion 132 elastically deforming under the pressing force of the body portion 131, and in order to make the flange portion 132 more easily elastically deforming under the pressing force of the body portion 131, it is further designed that the acute angle between the straight line of the first connection line 1321c and the central axis 13111 is α, and α satisfies the conditional expression: alpha is more than or equal to 30 degrees and less than or equal to 45 degrees; and/or an acute angle between a straight line of the second connecting line 1322c and the central axis 13111 is β, and β satisfies the conditional expression: beta is more than or equal to 30 degrees and less than or equal to 45 degrees. For example, α may be, but not limited to, 30 degrees, 35 degrees, 40 degrees, or 45 degrees, and β may be, but not limited to, 30 degrees, 35 degrees, 40 degrees, or 45 degrees. In the design, when the angle α is more than or equal to 30 degrees and less than or equal to 45 degrees and/or the angle β is more than or equal to 30 degrees and less than or equal to 45 degrees, through the inclination angle of the flange part 132 relative to the central axis 13111 of reasonable design, the flange part 132 can generate good elastic deformation under the effect of the extrusion force of the main body part 131, after the external force of the key 12 is cancelled, the resilience force generated when the flange part 132 of the elastic part 13 recovers deformation can also effectively assist the key 12 to rebound, so that the phenomenon that the key 12 cannot rebound in place can be effectively reduced, and the pressing hand feeling of the key 12 can be effectively improved.

As shown in fig. 4 and 5, it can be understood that the elastic element 13 is used for sealing the gap between the key 12 and the wall surface of the hole of the housing 11, and the elastic element 13 is also used for structurally supporting the key 12, and considering that the abutment between the flange portion 132 of the elastic element 13 and the housing 11 can be line contact or surface contact, in order to enhance the supporting strength of the elastic element 13 to the key 12, the elastic element 13 further includes a surrounding portion 133, the surrounding portion 133 is connected to the periphery of the flange portion 132, and the surrounding portion 133 is located on the side of the flange portion 132 away from the main body portion 131 and abuts against the housing 11. In the design, the surrounding part 133 is equivalent to a reinforcing rib in the elastic part 13, on one hand, the structural strength of the elastic part 13 is enhanced to improve the support stability of the key 12, and on the other hand, the surrounding part 133 is abutted against the shell 11, so that the contact area between the elastic part 13 and the shell 11 is increased, and the connection stability between the elastic part 13 and the shell 11 is also enhanced; the surrounding portion 133 abuts against the housing 11, and the surrounding portion 133 can also seal the housing 11 side, thereby further improving the good sealing performance of the elastic member 13.

The surrounding portion 133 and the flange portion 132 may be an integrated structure or a split structure, when the surrounding portion 133 and the flange portion 132 are the integrated structure, the surrounding portion 133 may be integrally formed on the flange portion 132 by injection molding, and when the surrounding portion 133 and the flange portion 132 are the split structure, the surrounding portion 133 may be fixed to the flange portion 132 by bonding with glue.

The surrounding portion 133 may be a block-shaped protrusion structure, and the surrounding portions 133 of a plurality of block-shaped protrusion structures are arranged at intervals around the circumference of the flange portion 132. In the embodiment of the present application, the surrounding portion 133 is an annular protruding structure, and the surrounding portion 133 of the annular protruding structure is disposed around the circumference of the flange portion 132.

As shown in fig. 1-3, in order to enhance the connection stability between the key 12 and the casing 11, the key 12 further includes a fastening portion 123, the fastening portion 123 is connected to a side of the first surface 1211 of the pressing portion 121, and the casing assembly 10 further includes a key holder, the key holder is disposed in the casing 11 corresponding to the key hole 111 and is in snap fit with the fastening portion 123. In the sum, the key holder is equivalent to a reinforcing rib for supporting the key 12, and the engaging portion 123 of the key 12 is in snap fit with the key holder, so that the connection stability between the key 12 and the housing 11 is enhanced.

In order to enhance the compactness between the key 12 and the housing 11, the outer surface 113 of the housing 11 is further provided with a sink 112 communicating with the key hole 111, and the side of the flange portion 132 away from the main body portion 131 is in contact with the bottom wall of the sink 112. In this design, the sunken groove 112 is equivalent to the accommodating space for accommodating the key 12 in the housing 11, and the key 12 is at least partially embedded in the sunken groove 112, so as to effectively improve the structural compactness between the key 12 and the housing 11, and certainly, a designer can design the key 12 to be embedded in the sunken groove 112 of the housing 11, and the appearance surface of the key 12 is flush with the appearance surface 113 of the housing 11, so as to enhance the overall aesthetic property of the housing assembly 10.

A second aspect of the present application proposes an electronic device comprising the above-described case assembly 10. The electronic device may be, but not limited to, an electronic device with a structure of keys 12, such as a mobile phone, a tablet computer, a smart watch, or a sports bracelet. In the electronic device with the shell assembly 10, the waterproof and dustproof sealing performance between the key 12 and the shell 11 is good, and a user has good pressing hand feeling for pressing the key 12.
