Referring to FIG. 3 and FIG. 4 together, each of the buttons 20 includes at least a keycap 21 and a connecting portion 23.

In the embodiment, the key cap 21 includes at least a body 211 and an extension portion 213. The body 211 includes a top wall 2111 and a peripheral wall 2113. The top wall 2111 is substantially rectangular. The peripheral wall 2113 is disposed around the circumference of the top wall 2111, and further forms a groove 2112 with the top wall 2111. Preferably, the peripheral wall 2113 is disposed perpendicular to the top wall 2111.

In this embodiment, the extension portion 213 is a ring structure. The extending portion 213 is disposed at an intermediate position of the groove 2112 and spaced apart from the peripheral wall 2113. The extension portion 213 and the top wall 2111 together form a receiving portion 2131. The extension portion 213 is provided with a hook portion 2133 for connecting the connection portion 23. Preferably, the extending portion 213 extends away from the end of the top wall 2111 in a direction toward the peripheral wall 2113 to extend out the hook portion 2133. The hook portion 2133 may be plural and evenly distributed around the extension portion 213. Of course, in other embodiments, the hook portion 2133 may be formed to extend away from the end portion of the extension portion 213 away from the top wall 2111 in a direction away from the peripheral wall 2113.

The connecting portion 23 includes a guiding portion 231 and an elastic portion 233. In the embodiment, the guiding portion 231 is movably connected to the hook portion 2133.

Specifically, the guiding portion 231 is a telescopic structure. The guiding portion 231 includes a base 2311 and a guide sleeve 2313. The base 2311 is mounted in the housing 10. The base 2311 has an annular structure. The base 2311 extends away from the surface of the housing 10 along a central position of the base 2311 to form a mating portion 2315.

The guide sleeve 2313 has an annular structure. The guide sleeve 2313 is movable relative to the base 2311 , and the guide sleeve 2313 can be received in the base 2311 . The guide sleeve 2313 includes a first edge 2312 and a second edge 2314 disposed opposite the first edge 2312. The first edge 2312 extends toward a central position of the guide sleeve 2313 to form a first protrusion 2316. The first protruding portion 2316 is matched with the hook portion 2133 to be in active contact with the hook portion 2133 to connect the key cap 21 . Further, the second edge 2314 extends in a direction away from the first protrusion 2316 to form a second protrusion 2318. The second protruding portion 2318 is matched with the engaging portion 2315 and is movably engaged with the engaging portion 2315 to connect the base 2311.

The elastic portion 233 is mounted in the housing 10 , and the elastic portion 233 is disposed corresponding to the receiving portion 2131 and abuts against the top wall 2111 . The elastic portion 233 is for supporting the key cap 21 . The key cap 21 is movable relative to the elastic portion 233 to drive the guiding portion 231 to move in opposite directions or opposite to the key cap 21 . Specifically, when the body 211 is pressed, the elastic portion 233 is deformed by the pressure of the key cap 21. At the same time, the guide sleeve 2313 gradually disengages from the hook portion 2133 as the body 211 moves, and is received in the base 2311. In this embodiment, the elastic portion 233 is an inflatable silicone. The gas in the aerated silicone is an inert gas.

Further, the elastic portion 233 is further provided with a card slot 2331. The elastic portion 233 is engaged with the housing 10 by the card slot 2331 to position the elastic portion 233 to prevent the elastic portion 233 from being displaced relative to the housing 10. In the embodiment, the card slot 2331 is disposed on a surface of the elastic portion 233 away from the key cap 21 . The card slot 2331 is a groove structure. Of course, in other embodiments, the elastic portion 233 can also be fixed to the housing 10 or the keycap 21 by means of bonding, screwing or the like.

In another embodiment, the extension 213 can be omitted. At this time, the elastic portion 233 is installed in the casing 10, and the elastic portion 233 is disposed corresponding to the groove 2112 and abuts against the top wall 2111. The hook portion 2133 is formed to extend in a direction toward or away from the elastic portion 233 at an end portion of the peripheral wall 2113 away from the top wall 2111.

Further, in the embodiment, the button 20 further includes a button post 215. The button post 215 is disposed in the accommodating portion 2131 and abuts against the elastic portion 233 . As such, when the body 211 is pressed, the elastic portion 233 is deformed by the pressure of the button post 215. The button post 215 is a cylindrical structure.

It can be understood that the button 20 further includes a sensor 25. Correspondingly, a circuit board 200 is further disposed in the casing 10. The sensor 25 is disposed on the circuit board 200 and is in contact with the elastic portion 233. In this embodiment, the shape and size of the card slot 2331 and the sensor 25 match each other. The sensor 25 is correspondingly disposed on the card slot 2331. Wherein, the sensor 25 is a pressure sensor.

Referring to FIG. 5 , it can be understood that, in this embodiment, before the button 20 is pressed, one end of the elastic portion 233 abuts against the button post 215 to support the key cap 21 . The other end of the elastic portion 233 is in contact with the sensor 25. At the same time, the first protruding portion 2316 on the guiding sleeve 2313 is engaged with the hook portion 2133 on the extending portion 213. The engaging portion 2315 of the base 2311 is engaged with the second protruding portion 2318 of the guide sleeve 2313. At this time, the body 211 is partially exposed to the casing 10, and the elastic portion 233 is not deformed.

Referring to FIG. 6, when the body 211 is pressed, the button post 215 moves in the direction of the elastic portion 233 with the body 211, and the elastic portion 233 is pressed to be elastically deformed. At this time, the button post 215 moves the extending portion 213 toward the elastic portion 233 such that the second protruding portion 2318 is separated from the engaging portion 2315. At the same time, the hook portion 2133 hooks the first protruding portion 2316, and drives the guiding sleeve 2313 to move away from the direction of the keycap 21 until the second protruding portion 2318 abuts against the circuit board. The first protruding portion 2316 is separated from the hook portion 2133 , and the guiding sleeve 2313 is received in the base 2311 . At this time, the elastic portion 233 triggers the sensor 25 to form a trigger signal under the pressure of the button post 215.

In summary, the button 20 is disposed on the housing 10 of the electronic device 100 and partially exposed on the outer surface of the housing 10. The guiding portion 231 adopts a telescopic structure, so that the button 20 has both a long keystroke and a small overall size. In addition, the button 20 has a simple structure and a better hand feel.
