Perhaps plastics are made into a structural member and then key part are dug on wooden shell or wood panel again on structural member
A hole, then structural member is fixed on plank with screw or other way.Structure is complicated for this method, directly affects wood
The globality and aesthetics of matter shell or wood panel, especially for the electric appliance for having seal request, it is easy to cause gas leakage.
Summary of the invention
The present invention is to lead to that structure is complicated using multiple independent keys in the electric appliance for overcome the prior art, influences wood panel
The technical issues of globality and sealing performance, provides a kind of insertion plank formula touch key-press.
In order to achieve the above object, technical solution provided by the invention is as follows:
A kind of insertion plank formula touch key-press comprising the blind hole that is set on the inner surface of the wooden shell of electric appliance and embedding
Enter to the pcb board in the blind hole, be provided with touch sensible chip on the pcb board and be connected with the touch sensible chip
Induction metal pad, the outer surface of the wooden shell is provided with multiple key symbols, the position of the multiple key symbols
It is corresponded with the position of the multiple induction metal pad.
Further, the pcb board is fixed in the blind hole by glue, double-sided adhesive or screw.
Further, the bottom of the blind hole and plank show that the thickness range for retaining part is 1-5mm.
Further, the key symbols are realized by the way of silk-screen, laser engraving or labeling.
Further, the induction metal pad and the touch sensible chip are respectively arranged at two of the pcb board
The one side that the induction metal pad is provided on face, and on the pcb board is disposed adjacent with the bottom surface of the blind hole.
Further, the touch sensible chip uses chip MM2323.
Further, the present invention also provides a kind of electric appliances, use above-mentioned insertion plank formula touch key-press.
Compared with the existing technology, the present invention has the advantage that and the utility model has the advantages that
A blind hole is arranged, in institute in insertion plank formula touch key-press of the invention on the inner surface of the wooden shell of electric appliance
It states and is embedded into pcb board in blind hole, be provided with touch sensible chip on the pcb board and be connected with the touch sensible chip
Incude metal pad, the outer surface of the wooden shell is provided with multiple key symbols, the position of the multiple key symbols with
The position of the multiple induction metal pad corresponds, when touching the key symbols, the induction metal pad
It generates sensor current signal and is transmitted to the touch sensible chip and responded, pressed without punching installation on wooden shell
Key, structure is simple, overall beautiful, good airproof performance.
Detailed description of the invention
Fig. 1 is the schematic cross-section of the insertion plank formula touch key-press of the embodiment of the present invention.
Fig. 2 is the schematic diagram of multiple key symbols in the embodiment of the present invention on wooden shell surface.
Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
As shown in Figure 1 and Figure 2, the embodiment of the invention provides a kind of insertion plank formula touch key-press comprising is set to wood
Blind hole 1 on 100 inner surface of matter shell and the pcb board 2 being embedded into the blind hole.Touch sensible is provided on the pcb board 2
Chip 21 and the induction metal pad 22 being connected with the touch sensible chip 21.The outer surface of the wooden shell 100 is set
It is equipped with multiple key symbols 3, one a pair of position of the position of the multiple key symbols 3 and the multiple induction metal pad 22
It answers.
The shapes and sizes of the blind hole 1 are corresponding with the pcb board 2, so that the pcb board 2 is embedded just below
In the blind hole 1.The pcb board 2 can be fixed in the blind hole 1 by glue, double-sided adhesive or screw.The blind hole
1 depth bounds are slightly larger than the thickness of the pcb board 2, so that the pcb board 2 can be completely embedded into the blind hole 2
In.The bottom of the blind hole and plank show that the thickness range for retaining part is 1-5mm.
It is described induction metal pad 22 size can determine according to actual needs, it is described induction metal pad 22 number
Amount is determined according to actual use quantity.The induction metal pad 22 and the touch sensible chip 21 are respectively arranged at described
The bottom of the one side and the blind hole 1 of the induction metal pad 22 is provided on two faces of pcb board 2, and on the pcb board 2
Face is disposed adjacent.
The effect of the induction metal pad 22 is felt for being formed with the finger for touching 3 corresponding position of key symbols
Capacitor is answered, it is mobile to detect human finger bring charge, to form inductive signal.The inductive signal is sent to the touching
Induction chip 21 is touched, the touch sensible chip 21 is used to judge finger according to the signal that the induction metal pad 22 senses
Touch action, to realize button operation.Chip MM2323 can be used in the touch sensible chip.
The wooden shell 100 does not limit solid wood board, can be original plank, medium density fiberboard, particieboard, the sham woods such as clamping plate
