The present invention is also directed to an electronic device including a housing, a main board disposed in the housing, and a switch component disposed on the main board, the electronic device including a button structure, the button structure being at least one a button and a gasket, a protrusion is formed on the lower surface of the button, and a hole is formed on the upper surface of the button, and the protrusion is movably received in the hole. The lower surface of the button is adhered to the upper surface of the gasket, and the housing is provided with a receiving hole. The button structure of the button structure is accommodated in the receiving hole, and the inner surface of the shell is adhered to the upper surface of the gasket.

The button structure of the present invention and the electronic device having the button structure can prevent water from penetrating from the button by adhering the lower surface of the button on the button structure to the upper surface of the pad.

Please refer to FIG. 1 to FIG. 2 , which is an electronic device 1 . The electronic device 1 includes a housing 10 , a main board 20 disposed in the housing 10 , a switch component 30 disposed on the main board 20 , and a button structure 40 movably received in the housing 10 and disposed opposite to the switch component 30 . The other components of the electronic device 1 are identical to the prior art electronic devices and are not listed here.

The housing 10 includes a first housing 101 and a second housing 102 that is engaged with the first housing 101. A first receiving hole 103 and a second receiving hole 104 are defined in the first housing 101 .

Referring to FIG. 3 to FIG. 4, the button structure 40 is composed of at least one button and a spacer 42. In a specific embodiment of the present invention, the button structure 40 is composed of two buttons, which are a first button 411 and a second button 412, respectively. The shim 42 is a rubber shim to provide better flexibility. In other embodiments, the gasket 42 may also be a gasket made of other elastic materials. The first button 411 is movably received in the first receiving hole 103 , and the second button 412 is movably received in the second receiving hole 104 , so that the button structure 40 is movably received in the casing 10 .

A first protrusion 401 is protruded from the lower surface 403 of the first button 411. A second protrusion 402 and a third protrusion 403 are protruded from the lower surface 405 of the second button 412. The upper surface 421 of the spacer 42 is provided with a first through hole 424 matching the first protruding portion 401, a second through hole 425 matching the second protruding portion 402, and a third through hole matching the third protruding portion 403. 426. The first protruding portion 401 is movably received in the first through hole 424 , and the second protruding portion 402 is movably received in the second through hole 425 . The third protruding portion 403 is movably received in the third through hole 426 . The lower surface of the button is adhered to the upper surface of the gasket, and the inner surface of the first casing 101 is adhered to the upper surface of the gasket 42, thereby preventing water from penetrating into the electronic device 1. In this embodiment, the lower surfaces of the first button 411 and the second button 412 are adhered to the upper surface of the gasket 42 by adhesive, and the inner surface of the first casing 101 is adhered to the gasket by adhesive. 42 upper surface.

Further, the upper surface of the spacer 42 is recessed inwardly around the first through hole 424 to form a first recessed portion 427. The upper surface of the spacer 42 is recessed inwardly around the second through hole 425 to form a second recessed portion 428. . The upper surface of the spacer 42 is recessed inwardly around the third through hole 426 to form a third recessed portion 429. The first recessed portion 427 is configured to provide a returning force to the first protruding portion 401 after the first protruding portion 401 is compressed by the external force, to help the first protruding portion 401 return to the position before pressing and prevent The first protrusion 401 has a plurality of button linkage problems due to the pulling force of the upper surface of the spacer 42 during pressing. The second recessed portion 428 is configured to provide a returning force to the second protruding portion 402 after the second protruding portion 402 is compressed by the external force, to help the second protruding portion 402 return to the position before pressing and The occurrence of a plurality of key linkage problems due to the pulling force of the upper surface of the spacer 42 during the pressing of the second protrusion 402 is prevented. The third recessed portion 429 is configured to provide a returning force to the third protruding portion 403 after the third protruding portion 403 is compressed by the external force, to help the third protruding portion 403 return to the position before pressing and The occurrence of a plurality of key linkage problems due to the pulling force of the upper surface of the spacer 42 during the pressing of the third protrusion 403 is prevented.

Referring to FIG. 5, when the electronic device 1 is assembled, the first protrusion 401 on the first button 411 and the second protrusion 402 and the third protrusion 403 on the second button 412 are first passed through the spacer. The first through hole 424, the second through hole 425 and the third hole 426 are attached to the upper surface of the spacer 42 and then the first button 411 and the second button 412 are respectively respectively The first protruding portion 401, the second protruding portion 402, and the third protruding portion 403 are respectively aligned with the switch member 30 on the main board 20, and the first housing 101 is received. The inner surface is adhered to the upper surface of the spacer 42 and finally the second housing 102 is engaged with the first housing 101.

When the button structure 40 is used, the user presses the first button 411 or the second button 412, the first protrusion 401 on the first button 411 or the second protrusion 402 and the third protrusion 403 on the second button 412. Compressing the spacer 42 under external force and contacting the switch member 30 on the main board 20 controls the electronic device 1 to perform a related operation. After the external force is released, the first recessed portion 427 and the second recessed portion 428 on the spacer 42 or The elastic recovery of the third recessed portion 429 drives the first button 411 or the second button 412 to return to the initial position. During the pressing process, since the first recessed portion 427, the second recessed portion 428 or the third recessed portion 429 can provide sufficient elasticity after being compressed, the first button 411 or the second button 412 is returned to the initial position, thereby It avoids the occurrence of multiple button linkage problems during pressing.
