Description
Affiliated technical field
The present invention relates to the to stroke key switch of operation particularly is loaded in as the key switch in the keyboard of the input unit of electronic instrument.The invention still further relates to the keyboard that is provided with a plurality of this key switchs.
Background technology
Slim in being assemblied in portable electron devices such as notebook computer type or palmtop computer promptly in the low clearance type keyboard, requires to impact the low level of the key switch of operation, and to improve its operability be good hand touch-----.Generally speaking, the key switch that can use in low clearance type keyboard is provided with: supporting bracket (for example, the lower raft of sheet metal or keyboard), be arranged on the keycap of supporting bracket top, interlock opens and closes the switching mechanism of the contact portion of circuit to support a pair of plastic rod parts of keycap towards the lifting direction guiding above supporting bracket corresponding to the elevating movement of keycap mutually.By the mutual interlock of a pair of plastic rod parts, keycap can be with respect to supporting bracket, keep the attitude of regulation towards vertical direction in fact, carries out elevating movement simultaneously.The operating characteristic of stroking of key switch can be subjected to the path increment of lifting action of described keycap and the influence of following in the lifting action operating characteristic of stroking of the so-called sensation of stroking.
Generally adopt slim plastics X support structure apparatus in the portable electron devices such as existing notebook type or palmtop computer.Hinged with the housing pivot hole on the housing connecting rod 8 referring to this device of Fig. 1, Fig. 2 by pivot 5 in the inside casing on the inside casing connecting rod 4, housing down hinge 9 and in lower slide of frame axle 7 respectively with metal profile 15 on rotation section 13 and sliding part 14 be rotating, be slidingly matched.On the plastics inside casing on hinge 10 and the plastics housing slide-bar 6 respectively with keycap 1 on keycap rotation section 2 and keycap sliding part 3 be rotating, be slidingly matched.Form plastics X support structure apparatus, and the rubber bullet circle 11 by being positioned at inside casing connecting rod 4 is with keycap 1 jack-up that makes progress.This key switch is mainly by being made of independent plastics X support structure apparatus, rubber bullet circle 11 etc. under keycap 1, thin film switch sheet 12, metal profile 15 and each keycap 1.
The switching circuit of the thin film switch sheet 12 under keycap 1 exposes keycap 1 time fully by a hundreds of technology through hole, and thin film switch sheet 12 influence that very easily is subjected to liquid causes short circuit in use,
The waterproof technology of thin film switch sheet 12 is very complicated, keyboard with 90 key positions is an example, thin film switch sheet 12 constitutes by the three-layer thin-film that is printed on 90 switch contacts, densely covered matrix circuit is superimposed, the three-layer thin-film that constitutes thin film switch sheet 12 simultaneously has the technology through hole about 500, make thin film switch sheet 12 waterproof must seal technology through hole about 500, while can't be polluted 90 switch contacts, densely covered matrix circuit causes and scraps, and existing viscose glue waterproof sealing complex process and technological requirement are higher.
(expose fully the cooperating of rotation section 13 on inside casing connecting rod 4 that 6mm * 10mm * 0.7mm) and intensity, rigidity are all relatively poor and housing connecting rod 8 and the metal profile 15 and sliding part 14 because size is very small keycap 1 time, plastics X supporting construction is influenced by slime body, dust, solid granule very easily and causes the feel variation, not clearing up use for a long time will cause plastics X supporting construction to lose efficacy
The hot-tempered sound that is unfavorable for keystroke simultaneously further reduces.
Summary of the invention
Technical problem to be solved by this invention provides the low outer bullet circle X support structure apparatus of a kind of cost of manufacture.
The technical solution adopted for the present invention to solve the technical problems is: comprising: between keycap 1 and thin film switch sheet 12 and support rubber bullet circle 11, the inside casing connecting rod 4 of keycap 1, the upper and lower side of housing connecting rod 8 is connected with keycap 1, supporting bracket 15 respectively, it is characterized in that: rotation section 13 and sliding part 14 that rubber bullet circle 11 contains on inside casing connecting rods 4, housing connecting rod 8 and the supporting bracket 15.
Further be: enclose 17 on the end connection bullet circle of rubber bullet circle 11 its bullet circle sidewalls 16, the other end of bullet circle sidewall 16 connects bullet circle lower wall 18, and the lower end of bullet circle lower wall 18 is connected with bullet circle foundation ring 19, and bullet circle sidewall 16 is mutually acute angle with bullet circle lower wall 18.
Further be: near the rubber bullet circle 11 bullet circle sidewall corresponding 16 thickened wall 23 can be arranged, also reinforcement 24 can be arranged with four bights of keycap (1).
Further be: rubber bullet circle 11 with the space of bullet circle through hole 20 about circle 17 is separated on the bullet circle, has bullet circle switch triggering platform 22 at the lower surface of bullet circle top brace 21 by bullet circle top brace 21.
Further be: the bottom of four sides of keycap 1 has inner groovy 1a
Good effect of the present invention is:
The X supporting construction keyboard that outer bullet circle X support structure apparatus of the present invention is applied to notebook computer has: the waterproof technology of significantly having simplified thin film switch sheet 12, the water resistance and the reliability of thin film switch sheet 12 have been improved, make rubber bullet circle 11 not only have the elastic reset effect simultaneously, also make it have the effect of anti-slime body, dust, solid granule plastics the influence of X supporting construction.
Because rubber bullet circle 11 has contained the X support structure apparatus, thereby having intercepted the hot-tempered sound of keystroke outwards propagates, the hot-tempered sound of keystroke further reduces, and simultaneously because the contact-making surface of rubber bullet circle 11 and keycap 1 is near the outer rim of lower surface of keycap 1, helps the further raising of keystroke feel.
Should can be widely used in computer keyboard, palmtop computer, all kinds of embedded keyboard and the key switch of the operation of stroking by outer bullet circle X support structure apparatus.
