Description
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 the portable electron devices such as laptop type or palmtop computer namely 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-----.The key switch that can use in low clearance type keyboard generally speaking, is provided with: supporting bracket (for example, the lower raft of sheet metal or keyboard); Be arranged on the keycap of supporting bracket top; Mutually link and be installed in a pair of plastic rod parts towards vertical direction guiding and supporting keycap of the top of supporting bracket; Open and close the switching mechanism of the contact section of circuit corresponding to the elevating movement of keycap.Mutually link by a pair of plastic rod parts, keycap can be with respect to supporting bracket, remain parallel to the attitude of supporting bracket towards vertical direction in fact, carries out simultaneously elevating movement.The operating characteristic of stroking of key switch can be subject to the path increment of the lifting action of described keycap, rigidity, plastic rod parts and the keycap fit clearance of plastic rod parts, and the impact of following the operating characteristic of stroking of the so-called sensation of stroking in the lifting action.
Generally adopt thin plastic 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 plastics outside connecting rod 8 by pivot 5 in the plastics on the plastics inside connecting rod 4 referring to this device of Fig. 1, Fig. 2 (formation of the support structure apparatus of a keycap), in the outer down hinge 9 of plastics and the plastics lower slide-bar 7 respectively with supporting bracket 15 on support plate rotation section 13 and support plate sliding part 14 be rotating, be slidingly matched.On the plastics the outside upper slide-bar 6 of hinge 10 and plastics respectively with keycap 1 on keycap sliding part 3 and keycap rotation section 2 be and be slidingly matched, be rotatably assorted.Form plastics X support structure apparatus, and by being circular arch shape action component--rubber bullet circle 11 is with keycap 1 jack-up upwards, and the linkage portion of outside connecting rod 8 and inside connecting rod 4 is rotatably assorted with pivot hole by the middle pivot 5 that lays respectively at outside connecting rod arm, inside connecting rod arm near middle and consists of; The connecting portion that outside connecting rod 8, inside connecting rod 4 are connected with keycap 1 and supporting bracket 15 respectively by be distributed in respectively outside connecting rod arm, inside connecting rod arm upper end or the interior upper hinge 10 of lower end, interior lower slide-bar 7 and outside upper slide-bar 6, outer down hinge 9 consists of.The plastics X support structure apparatus that mainly is made of the pair of links of the mutual interlock under keycap 1, thin film switch sheet 12, supporting bracket 15, the keycap 1 referring to Fig. 1, Fig. 2, this key switch, rubber bullet circle 11 etc. consist of.
Wherein rubber bullet circle 11 is fixed on thin film switch sheet 12 upper surfaces and corresponding with the indent lower surface of keycap 1, thin film switch sheet 12 is fixed on the upper surface of supporting bracket 15, support plate rotation section 13 on the supporting bracket 15 and support plate sliding part 14 pass the corresponding through hole on the thin film switch sheet 12, and be positioned near the thin film switch sheet 12 upper surfaces top, by plastics outside connecting rod 8, the lower end of the link supports that plastics inside connecting rod 4 consists of respectively with supporting bracket 15 on support plate rotation section 13 and support plate sliding part 14 rotate, be slidingly connected, its upper end respectively with keycap 1 on keycap sliding part 2 and keycap rotation section 3 be rotating, be slidingly matched.
Although be widely used in the low clearance keyboard by the plastics inside connecting rod 4 of mutual interlock, the link supports parts (afterwards referred to as plastic rod) that plastics outside connecting rod 8 consists of, there is following some deficiency in it always:
1, small (high (the sectional dimension 0.7mm of plastic rod arm * 1mm) of 6mm * 10mm * 0.7mm), rigidity requirement of plastic rod structure.Many employings of present stage high strength plastics is produced still and can not be satisfied rigidity requirement, and material cost is always high.
2, the plastic rod structure smaller, have hole axle construction, production technology more complicated.All there was side core-pulling in the mould of production and application (mould structure was complicated present stage, cost is high, and the defectives such as injection moulding deficiency appear in the production process easily), and a large amount of production must be adopted hot channel injecting formation (the injection molding machine input cost is high, energy consumption high).
3, the production of existing keyboard, packaging technology complexity:--punching production of supporting bracket panel beating--is assembled into plastics X support structure apparatus with plastic rod--the X support structure apparatus is assembled in supporting bracket in plastic rod injection moulding production, the packaging technology efficient of existing keyboard is low, and cost is high.
Each parts comparision of production of keyboard disperses, and the turnover cost is relatively high.
4, the fit clearance of plastic rod (0.08mm-0.12mm), plastic rod respectively with supporting bracket, keycap close gap also large (0.08mm-0.12mm), with regard to the keyboard by common 2.5mmm stroke, when finger stroke arrived the edge of keycap, keycap is impacted a side the idle stroke of the side displacement of 0.24mm---0.36mm.
5, the sectional dimension 0.7mm of plastic rod arm * 1mm, four pitman arm take up spaces that form plastics X support structure apparatus are 2.8mm, rubber bullet circle minimum diameter is 4.5mm, consider the fit clearance between connecting rod, connecting rod and rubber bullet circle do not interfere headspace, keycap and connecting rod do not interfere headspace, the existing extra small keycap minimum dimension in one direction that adopts the keyboard of plastic rod be 8.5mm (the first row of existing keyboard be the F key and up and down key all adopt little key), just be of a size of the keyboard of 15mm * 15mm by the standard keycap, the optimum size 15mm * 7.2mm of extra small keycap.
Although 6, plastic rod adopts high-strength engineering plastics to improve rigidity, further improve operability, its rigidity still causes not when finger stroke arrives the edge of keycap, and keycap is impacted a side the idle stroke of the side displacement about 0.5mm.
Produce existing keyboard of notebook computer equipment needed thereby:
Produce the injection molding machine of keycap
Connecting rod injection-moulding device-----high speed and precision injection molding machine----hundreds of thousands/platform
-----injection moulding can be produced two pairs of---die cost 1,000,000---2,000,000 of hot runner mould of 64 small rods to the connecting rod injection mold, a keyboard needs 90 pairs of connecting rods, suppose die life 1,000,000 times, the die cost of each keyboard is at 1.2 yuan/---and 2.4 yuan/.
The material cost of pressing equipment, diel link supports and die cost in rubber bullet circle production equipment, the metal profile, production technology cost and the installation cost that link supports is installed on the supporting bracket are high, are that the keyboard of notebook computer cost is far above the principal element of conventional desktop computor-keyboard.Simultaneously plastic rod poor rigidity, fit clearance are large, are the keyboard of notebook computer urgent problems.
How to enhance productivity and reduce the keyboard of notebook computer of link supports cost is arranged, how to improve the durability (also namely improving the very thin durability of moulding section's link supports of structure) of keyboard of notebook computer, how to improve connecting rod rigidity and reduce fit clearance, when thereby the minimizing finger stroke arrives the edge of keycap, the idle stroke of the side displacement when keycap is impacted.Become and perplexed keyboard of notebook computer manufacturer hard nut to crack so far always.
