Every other embodiment obtained under the premise of creative work is made, shall fall in the protection scope of this application.
Fig. 1 and Fig. 2 are please referred to, the embodiment of the present application provides a kind of electronic equipment 100, including shell 10, side key 20, side
Button circuit board 30, the first waterproof case 40 and the second waterproof case 50, shell 10 is equipped with side key channel 22 and side key accommodates
Chamber 24, side key 20 protrude into side key channel 22 along first direction and are partially disposed in side key accommodating chamber 24；Side key circuit
Plate 30 is set to side key accommodating chamber 24, and side button circuit board 30 includes contact 26 (Dome)；First waterproof case 40 is set to side
The circumferential direction of key 20 is simultaneously interference fitted with shell 10；Second waterproof case 50 between side key 20 and side button circuit board 30,
Second waterproof case 50 is connected to side key 20 and is interference fitted with contact 26.
Shell 10 can be the front housing or center component of electronic equipment 100, for carrying the various electricity of electronic equipment 100
Subcomponent, such as battery, display screen etc..Electronic equipment 100 can be intelligent mobile terminal, tablet computer, handheld terminal, electricity
The equipment such as sub- reader.
Shell 10 offers side key channel 22 and side key accommodating chamber 24, side key channel 22 and side key accommodating chamber 24
It is interconnected, side key channel 22 is the channel that side key 20 extends into, and direction is first direction X.Side key accommodating chamber 24
For accommodating end 27 and the side button circuit board 30 of side key 20.The general waterproof seal that can only pay close attention to side key 20, example
Such as the sealing waterproofness in side key channel 22, but few technical solutions are concerned about the sealing waterproof of side key accommodating chamber 24
Property.
Side key 20 is the key positioned at 10 side of shell, such as can be the function buttons such as volume adjustment key, closing key.
Side key 20 includes keycap 28 and key column 29, and keycap 28 is located at one end of key column 29 and part is exposed.The other end of key column 29
Side key channel 22 is protruded into along first direction X, and the end 27 of key column 29 is placed in side key accommodating chamber 24.
Side button circuit board 30 is the circuit board connecting with side key 20, and side button circuit board 30 is arranged in shell 10
Portion, side button circuit board 30 include contact 26, and side key 20 is electrically connected with contact 26.
First waterproof case 40 is set to the circumferential direction of side key 20 and is interference fitted with shell 10, specifically, side key 20
The outer diameter of key column 29 is less than 22 internal diameter of side key channel, to reserve certain gap between key column 29 and shell 10.First
Waterproof case 40 is the circumferential direction for being set in side key 20, and the first waterproof case 40 is annular in shape, from section, the ring of the first waterproof case 40
The gap width being wider than between key column 29 and shell 10 improves side key to form the relationship of interference fit with shell 10
20 sealing waterproofness.The quantity of first waterproof case 40 can be 1,2 or multiple, mainly with the length of side key 20
And the structure of shell 10 is reference, such as gap distribution between shell 10 and key column 29 it is uneven, when varying, can be with
First waterproof case 40 of multiple and different thicknesses is targetedly set respectively.
To further increase the sealing waterproofness for putting the first waterproof case 40, in one embodiment, the first waterproof case 40
It is an integral molding structure with side key 20.Specifically, in one embodiment, the material of side key 20 be aluminium alloy, first
The material of waterproof case 40 is that silica gel, side key 20 and the first waterproof case 40 pass through hydro-forming formation integral structure, such as silica gel
The molded method of fluid oil.
In 20 container of side key, 27 position of end of side key 20 one end container can be further set
270, for accommodating the end 27 of side key 20, and obstruct around possible steam approaching side key 20 and side button circuit board 30
The region touched.
The size of the junction of the end 27 and key column 29 of side key 20 becomes smaller, and receives to make side key 20 protrude into side key
It is not easy to exit after cavity 24, here in order to further block side key 20, a settable side switch spacing shim 25, with solid
The position for determining side key 20 is unlikely to deviate or drop out.
For second waterproof case 50 between side key 20 and side button circuit board 30, the second waterproof case 50 is connected to side key
20 and with contact 26 be interference fitted.
