In a preferred embodiment of the invention, be provided with a bracing frame in described key base, this bracing frame passes through the second stressed rear easy fracture anatomical connectivity on the inwall of described key base.
In a preferred embodiment of the invention, support frame as described above is a T-shaped bracing frame, adopt the second stressed rear easy fracture anatomical connectivity between the transverse arm two ends of described T-shaped bracing frame and the inwall of described key base, the vertical arm lower end of described T-shaped bracing frame acts on described clear switch.
In a preferred embodiment of the invention, described first stressed rear easy fracture structure is dot structure.
In a preferred embodiment of the invention, described second stressed rear easy fracture structure is dot structure.
Owing to have employed technical scheme as above, the present invention compared with prior art has the following advantages:
1, reduce wiring board area, reduce the cost of wiring board.
2, without the need to doing structure in the circuit board, avoid borehole, grooving destroys wiring board, improves wiring board winding displacement, puts the usable area of components and parts.
3, structure is simple, and product mold is easily manufactured, and stability is strong.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of knob of the present invention.
Fig. 2 is the structural representation of knob dial-up dish of the present invention.
Fig. 3 is the structural representation of keypad of the present invention.
Fig. 4 is the view before knob crumple of the present invention.
Fig. 5 is the view after knob crumple of the present invention.
Embodiment
The present invention is further described below in conjunction with the drawings and specific embodiments.
Button cap 100, case ring 200, key base 300, knob 400, knob dial-up dish 500, firm banking 600 and clear switch 700 is comprised see the knob assembly provided in Fig. 1, Fig. 1.
Firm banking 600 and clear switch 700 are fixed on wiring board 800, and firm banking 600 is a hollow structure, and clear switch 700 is positioned at the center of firm banking 600.
For hollow structure, it overlaps and is supported on firm banking 600 knob dial-up dish 500, and the rotation of knob dial-up dish 500 will be stirred and be dialled volume switch (not shown).
Knob 400 to be enclosed within knob dial-up dish 500 for hollow structure and to drive knob dial-up dish 500 to rotate.
Key base 300 inserts in knob 400, knob dial-up dish, firm banking successively, and button cap 100 is arranged on key base 300, and case ring 200 inserts in the gap between key base 300 and knob 400 and also supports by key base 300 and knob 400.
In conjunction with see Fig. 2, be connected with a support annulus 520 at knob dial-up dish 500 by some fulcrum structures 510, support annulus 520 in order to support knob 400.
In conjunction with see Fig. 3, a bracing frame is provided with in key base 300, bracing frame is a T-shaped bracing frame 310, adopts fulcrum structure 320 to be connected between transverse arm 31 1 two ends of T-shaped bracing frame 31 0 and the inwall of key base 300, and vertical arm 312 lower end of T-shaped bracing frame 310 acts on clear switch 700.
The structure of the crumple endergonic structure of above-mentioned knob is simple, easily manufactured, stability is strong, wiring board (PCB) is not destroyed when there is crumple, avoid borehole, grooving in the circuit board, add the usable area of wiring board, facilitate electronic cable and components and parts are put, because this structure technology crumple is by knob portion complete independently, not strong with wiring board relevance, therefore more save the area (saving the area of about 25% ~ 40%) of wiring board (PCB), greatly save the cost of wiring board (PCB).
The operation principle of the crumple endergonic structure of above-mentioned knob is:
Case ring 200 extrudes the support annulus 520 on knob dial-up dish 500 together with knob 400 when being subject to downward pressure, when power reaches 300 ± 50N, 6 fulcrum structures 510 supported between annulus 520 and knob dial-up dish 500 rupture, case ring 200, knob 400, support annulus 520 sink to producing displacement, and sinking distance is the sinking height h identified in Fig. 4.
When button cap 100 is subject to downward pressure, pressure is imparted to key base 200, when power reaches 300 ± 50N, 2 fulcrum structures 320 between T-shaped bracing frame 31 0 and key base 300 inwall rupture, and button cap 100, key base 200 occur to sink to producing displacement.
Below the invention main points of crumple technology for this reason, the fulcrum structure that fracture occurs is plastic material, and can execute according to the external world fracture pressure that stressed size adjusts each fulcrum structure, has very strong flexibility.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-mentioned specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection range is defined by appending claims and equivalent thereof.
