Specific embodiment
With reference to embodiment and compares attached drawing the utility model is described in further details.It is wherein identical
Appended drawing reference indicates identical component, unless stated otherwise.It is emphasized that following the description is only exemplary,
Rather than in order to limit the scope of the utility model and its application.
Fig. 1 is the broken section structural schematic diagram after all parts of waterproof key component are assembled together.This is practical new
The waterproof key component of type, as shown in Figure 1, including key 1, key sealing 2, control panel 3, control switch 4.The knot of key 1
Structure as shown in Fig. 2, the inside top surface of key 1 (" inside " herein refers in Fig. 1 in assembly towards " pcb board control switch 4 "
Direction) by the position of two close end be equipped with button buckle 11, be equipped with key compression bar 13 close to intermediate position, and in key
Direction on 1 from top surface toward inside has extended to form key boss 12.Preferably, key 1 is made of plastic material.
The structure of key sealing 2 is as shown in figures 1 and 3, including skew wall 21 and positioning convex platform 23, and key seals during installation
2 is bowl-shape in the strip of back-off, and offers hole location 22 in bowl-shape bottom, hole location 22 be respectively used to button buckle 11, by
Key compression bar 13 is interference fitted, and key sealing 2 is made of silica gel, rubber elastomeric material.Assembly when, first by key 1 with press
Key sealing 2 is assembled together, the two be assembled together after structure as shown in figure 4,1 both ends of key button buckle 11 and centre
Key compression bar 13 be respectively assembled at key sealing 2 hole location 22 in, the key boss 12 of key 1 be located at key seal 2 it is oblique
The top of wall 21.
The structure of control panel 3 is as shown in Figure 1 and Figure 5, can be set more than one slot position 32 on control panel 3, and one
1, the key sealing 2 of the corresponding key of a slot position 32 and a control switch 4, the two sides of the bottom of each slot position 32 are opened
Equipped with button hole 31, centre offers strut kong 33, wherein button hole 31 is for assembling button buckle 11, and strut kong 33 is for filling
With key compression bar 13 and control switch 4.Control switch 4 is located in PCB circuit board, as shown in fig. 6, can set in PCB circuit board
Set more than one control switch 4.
In assembly, first key 1, key sealing 2 are assembled together, the two be assembled together after structure such as Fig. 4 institute
Show, then the two is assembled in the slot position 32 of control panel 3 again, wherein the positioning convex platform 23 of key sealing 2 is stuck in slot position 32
Bottom and be interference fitted with slot position 32, the button buckle 11 of key 1 is inserted into the button hole 31 of control panel, key 1, key
Sealing 2, control panel 3, the structure after control switch 4 is assembled together are as shown in Figure 1.When pressing down on key 1, key is close
Envelope 2 by pressure flexible deformation, is embodied in the skew wall 21 of key sealing 2 to lower recess in key 1, then key compression bar 13
Touch control switch 4 makes its movement.After the active force acted on key 1 removes, 2 rebound of key sealing restores original
Shape, so that key 1 resets.
In the present invention, key sealing 2 is arranged between key 1 and control panel 3 by compression, since key seals
Hole location 22 on 2 is interference fitted with button buckle 11, key compression bar 13 respectively, and the positioning convex platform 23 in key sealing 2 is stuck in slot
It the bottom of position 32 and is interference fitted with slot position 32, therefore, key sealing 2 can play sealing waterproof action, so that external
Water will not enter PCB circuit board.In addition, key 1, when moving up and down, key sealing 2 is tied by the bowl-shape elasticity of its back-off
Structure also acts as good rebound effect, so that the button assembly of the utility model is not in clamping stagnation, recess in normal action
Defect, and then phenomena such as avoid card key.In addition, by the way that positioning convex platform 23 is arranged in key sealing 2, when key 1 is super in pressing
When stroke, the position that key boss 12 is limited by positioning convex platform 23 is realized, so as to avoid 4 quilt of control switch on pcb board
Damage.
In addition, in the present invention, button buckle 11 passes through the hole location 22 of key sealing 2, and is buckled in control panel 3
On button hole 31 in, when carrying out button operation, hole location 22, button hole 31 play guiding role to button buckle 11, in addition, control
Slot position 32 on panel 3 processed also functions to guiding role to key boss 12, this structural advantages is, can for strip key
To guarantee that key is not in wide-angle deviation, its position is made arbitrarily will not to deviate or shake, and is set when on control panel
When setting more keys, as long as setting the position of slot position 32 and button hole 31 on the control panel, it will be able to determine the position of key 1
It sets, realizes overall aesthetics.
In addition, the waterproof key component of the utility model, key 1 is directly realized by by key compression bar 13 on pcb board
Control switch 4 is pressed, and middle flexible material is avoided, to improve handfeel of keys.In addition, it can be seen from figure 4 that
After the button assembly of the utility model assembles, the key boss 12 of key 1 is located at the upper of the skew wall 21 of key sealing 2
Side, when about 1 push action of key, residual moisture content can be squeezed out the slot position 32 of control panel by key boss 12.Excellent
In the embodiment of choosing, control panel slot position 32 is skew wall slot, as shown in fig. 7, the position dimension of notch is big, the position dimension of slot bottom
It is small, it is designed in this way, it is convenient with 2 assembly of key sealing, and the shape of positioning convex platform 23 will not be made to be squeezed and deformed, meanwhile, when pressing
When about 1 push action of key, residual moisture content is easier to be squeezed out the slot position 32 of control panel by key boss 12.And in the reality
Apply in example, after button buckle 11 is buckled on control panel 3, positioning convex platform 23 equally meet be stuck in slot position 32 bottom and
It is interference fitted with slot position 32, so that sealing waterproof action is played in key sealing 2.
In addition, in a preferred embodiment, being additionally provided with the hook portion for limit in the bottom end of button buckle 11, such as scheme
Shown in 1 and Fig. 2, after all parts of button assembly assemble, the button buckle 11 at 1 both ends of key is inserted into control plane respectively
In the corresponding button hole 31 of board ends, the hook portion of button buckle 11 can be contacted with the bottom surface of control panel, as shown in Figure 1, can also
Not contact, may exist certain gap therebetween.As shown in Figure 1, when left and right one end of pressing keys 1, key 1 by
A degree of inclination can occur in See-saw effect, the button buckle 11 for being pressed one end can be along corresponding on control panel 3
Button hole 31 move downward, the button buckle 11 of the other end can be upturned along button hole 31 corresponding on control panel 3, herein
In the process, the button hole 31 on control panel plays guiding role to the movement of button buckle 11, deviate its movement will not, and
When the button buckle 11 of 1 other end of key is upturned, the hook portion of the button buckle 11 by resisting the bottom of control panel,
So as to limit See-saw effect so that when one end of key 1 is pressed, the other end of key 1 will not stick up it is very high so that
Key 1 is whole to be pulled down, so that key compression bar 13 can press control switch 4.Meanwhile key sealing 2 passes through
Its bowl-shape elastic construction being buckled to has good rebound effect, and therefore, the waterproof key component of the utility model can be avoided
The defects of keyed recess or switch are failure to actuate when pressing left and right one end.
The waterproof key component of the utility model, application places can be applied on any electric appliance without limiting.In
In one embodiment, the waterproof key component of the utility model is applied on dish-washing machine, since dish-washing machine is generally placed on kitchen
In, and kitchen is greasy dirt important place, the surface of dish-washing machine can be by frequent wiping cleaning, and therefore, the surface of general dish-washing machine is right
Waterproof has certain requirement.
