In one embodiment of the present application, the material of the engaging element 20 is preferably tpu (thermoplastic polyurethanes) soft rubber, and in other embodiments, the material of the engaging element 20 may also be a soft material such as rubber, which is not limited herein.

Referring to fig. 4, fig. 5 and fig. 6, fig. 5 is a schematic structural view of an embodiment of the second frame 130, and fig. 6 is a schematic structural view of an embodiment of the fitting member 20. The mating member 20 includes a first protrusion 210 and a second protrusion 220 spaced apart from each other, and the first protrusion 210 and the second protrusion 220 respectively include at least two abutting ends. When the fitting member 20 is engaged with the key mounting hole 330 along with the extending post 110, the abutting end abuts against the sidewall of the key mounting hole 330 to limit the key body 10. Further, in an embodiment of the present application, the first protrusion 210 and the second protrusion 220, which are projections of the mating member 20 along the axial extension direction of the extension column 110, both protrude from the circumferential profile of the extension column 110, and when the key body 10 is mated with the mating member 20 and the key installation hole 330, the first protrusion 210 and the second protrusion 220 protruding from the extension column 110 abut against the key installation hole 330 to implement installation. In the process of pressing and rebounding the key body 10, compared to the size of the contact area between the conventional key and the key mounting hole 330, the abutting end of the first protruding portion 210 and the abutting end of the second protruding portion 220 of the present application abut against the key mounting hole 330 respectively, specifically refer to fig. 7 and 8, fig. 7 is a schematic structural diagram of a state of the key assembly 320 shown in fig. 4, and fig. 8 is a schematic structural diagram of another state of the key assembly 320 shown in fig. 4. Please refer to the abutting end X, the abutting end Y, the abutting end Z, and the abutting end W shown in fig. it should be noted that the abutting end X and the abutting end Y are disposed at intervals, and the abutting end Z and the abutting end W are disposed at intervals, so when the abutting end X, the abutting end Y, the abutting end Z, and the abutting end W abut against the sidewall of the key mounting hole 330, the effective contact area between the key body 10 and the key mounting hole 330 is small, and the friction force received when the key body 10 moves in the key mounting hole 330 is greatly reduced, so that the key body 10 is not easy to have the problem of hard hand feeling and difficult pressing of the conventional key in the pressing and rebounding processes. In addition, the four abutting ends of the first protruding portion 210 and the second protruding portion 220 can respectively play a lever role, so that the positioning and anti-shaking effects on the key body 10 are good.

The extending column 110 is provided with a first position-limiting part 1110 and a second position-limiting part 1120, and the fitting member 20 is provided with a third position-limiting part 230 matched with the first position-limiting part 1110 and a fourth position-limiting part 240 matched with the second position-limiting part 1120; when the first position-limiting portion 1110 is engaged with the third position-limiting portion 230, the fourth position-limiting portion 240 is sleeved on the second position-limiting portion 1120, so that the engaging member 20 is engaged with the extension column 110. In the long-time pressing and rebounding process of the key body 10, the first protrusion 210 and the second protrusion 220 of the fitting member 20 are always in a state of friction with the key mounting hole 330, and therefore the connection between the fitting member 20 and the key body 10 needs to be in a stable state to ensure the service life of the key body 10.

Referring to fig. 4, in an embodiment of the present application, the first limiting portion 1110 is a limiting groove, the limiting groove is uniformly arranged around the extending column 110 in the axial direction, and the third limiting portion 230 is a limiting protrusion matching with the limiting groove; the second limiting portion 1120 is disposed at one end of the extending column 110 away from the key body 10, the second limiting portion 1120 is a limiting column extending toward the key mounting hole 330, and the fourth limiting portion 240 is a limiting collar sleeved on the limiting column. It can be understood that the fourth position-limiting portion 240 is sleeved on the second position-limiting portion 1120 when the first position-limiting portion 1110 and the third position-limiting portion 230 are limited by the limiting groove and the limiting protrusion. With this arrangement, the fitting member 20 is hardly moved while reciprocating along the key mounting hole 330, so that the stability of the fitting member 20 is improved. In other embodiments, the first position-limiting portion 1110 may be a position-limiting protrusion, and the third position-limiting portion 230 may be a position-limiting groove matched with the position-limiting protrusion. Meanwhile, the second position-limiting portion 1120 is a position-limiting sleeve ring, and the fourth position-limiting portion 240 is a position-limiting post matched with the position-limiting sleeve ring.

Referring to fig. 9 and 10 and fig. 11, fig. 9 is a top view of the electronic device 30 shown in fig. 1, fig. 10 is a cross-sectional view taken along line a-a shown in fig. 9, and fig. 11 is an enlarged schematic structural diagram taken along line C shown in fig. 10. The key body 10 includes a first frame 120 and a second frame 130 detachably connected to each other, the first frame 120 is partially sleeved outside the second frame 130, and the extension column 110 is connected to the second frame 130 and extends along a direction away from the first frame 120.

The first frame 120 has an accommodating groove 1210, and one side of the second frame 130 facing the first frame 120 has a protrusion 1310 adapted to the accommodating groove 1210. In an embodiment of the present invention, an extending direction of the receiving groove 1210 is consistent with an extending direction of the long side of the first frame 120, an extending direction of the engaging protrusion 1310 is also consistent with an extending direction of the long side of the first frame 120, and a size of the engaging protrusion 1310 corresponds to a size of the receiving groove 1210. It is understood that, in other embodiments, the first frame 120 may be provided with a matching protrusion 1310, and the second frame 130 is provided with a receiving groove 1210 facing to a side of the first frame 120 and matching with the matching protrusion 1310. Whether the first frame 120 or the second frame 130 is provided with the receiving groove 1210 or the first frame 120 or the second frame 130 is provided with the engaging protrusion 1310 is within the protection scope of the present application, and is not limited herein.

The first frame body 120 is provided with a first engaging member 1230 and a second engaging member 1250 at two opposite sides along the extending direction of the accommodating groove 1210, and the second frame body 130 is provided with a first engaging groove 1320 matched with the first engaging member 1230 and a second engaging groove 1330 matched with the second engaging member 1250. In an embodiment of the present invention, the first engaging member 1230 and the second engaging member 1250 are disposed at opposite sides and opposite corners of the accommodating groove 1210, and when the first engaging member 1230 and the second engaging member 1250 simultaneously engage with the first frame 120 and the second frame 130, the second frame 130 may not be separated from the first frame 120. It can be understood that, in the present application, the first frame body 120 is provided with one first engaging member 1230 and one second engaging member 1250 respectively at two opposite sides of the receiving groove 1210, in other embodiments, the first frame body 120 may also be provided with a plurality of first engaging members 1230 and second engaging members 1250 respectively at two opposite sides of the receiving groove 1210 to mount and position the first frame body 120 and the second frame body 130, so that when the first frame body 120 and the second frame body 130 reciprocate in the key mounting hole 330, the second frame body 130 is difficult to separate from the first frame body 120. It is noted that, in the description of the present application, "a plurality" means at least two, e.g., two, three, etc., unless explicitly specified otherwise. FIG. 6 illustrates only one embodiment of the present application and not all embodiments of the present application.

With reference to fig. 4 and fig. 11, the first engaging member 1230 and the second engaging member 1250 both include an extending portion 1260 and an engaging portion 1270, the extending portion 1260 of the first engaging member 1230 and the second engaging member 1250 respectively matches with the first engaging groove 1320 and the second engaging groove 1330, the engaging portion 1270 is vertically disposed along the extending direction of the accommodating groove 1210, and an end surface of the engaging portion 1270 far away from the extending column 110 abuts against an end surface of the extending column 110 of the second engaging member 1250. It can be concluded that, when the engaging portion 1270 is vertically disposed along the extending direction of the receiving groove 1210, the second frame 130 is further limited, and the mounting stability between the second frame 130 and the first frame 120 is improved.

The fitting 20 further includes a first retaining portion 250 and a second retaining portion 260, which are oppositely disposed, the first retaining portion 250 and the second retaining portion 260 extend outward along the axial direction of the extension column 110, and the outer circumferential dimensions of the first retaining portion 250 and the second retaining portion 260 are at least partially larger than the circumferential dimension of the axial cross section of the extension column 110; the section size of the anti-drop part along the extending direction of the extending column 110 is gradually reduced. The movable distance of the key body 10 in the key mounting hole 330 is constant, and the first and second

anti-separation portions

250 and 260 mainly prevent the key body 10 from separating from the key mounting hole 330 when the key body 10 moves in the key mounting hole 330, thereby limiting the movable distance and space of the key body 10. Because the fitting member 20 is made of a soft material, and the fitting member 20 is in interference fit with the key mounting hole 330, when the key body 10 drives the fitting member 20 to fit with the key mounting hole 330, the resistance applied when the key body 10 and the fitting member 20 are mounted needs to be reduced, so in an embodiment of the present application, the cross-sectional dimensions of the first anti-separation portion 250 and the second anti-separation portion 260 are gradually reduced along the extending direction of the extending column 110. That is, in the process of matching the key body 10 with the mating member 20 and the key mounting hole 330, the smaller cross-sectional ends of the first and second retaining

portions

250 and 260 enter the key mounting hole 330 first, and then enter the key mounting hole 330 after the larger cross-sectional size. So set up, be more favorable to the cooperation of button body 10 and button mounting hole 330. Further, one side of the first anti-separation portion 250 and the second anti-separation portion 260 away from the first frame body 120 is a chamfer, so that resistance received when the extension column 110 is matched with the key mounting hole 330 is reduced.

It should be noted that the first anti-disengaging portion 250 and the second anti-disengaging portion 260 are accommodated in the second mounting hole 3320, and the second mounting hole 3320 is used for limiting the first anti-disengaging portion 250 and the second anti-disengaging portion 260, so that the fitting piece 20 and the key body 10 are not easily disengaged from the key mounting hole 330 after the fitting piece 20 and the key body 10 are mounted. And the second mounting hole 3320 also defines a movable distance between the key body 10 and the mating member 20 when the key body 10 and the mating member 20 are pressed and rebounded in the key mounting hole 330, so that the key body 10 and the mating member 20 are moved. In addition, the conductive base pillar 140 is correspondingly provided with a fitting hole 1420 for installing the conductive base pillar 140 and the conductive connecting assembly 340.
