Description
The bond structure device and its installation method of a kind of new button cap structure
Technical field
The present invention relates to the key switch of operation of stroking is carried out, the key switch in the keyboard as the input unit of electronic instrument is more particularly to loaded in.
Background technology
It is slim in the portable electron devices such as laptop type or palmtop computer are assemblied in, i.e. in low clearance type keyboard, it is required that carrying out the low level of the key switch of beating operation, and improving its operability, i.e. good hand touch --- generally, the key switch used in low clearance type keyboard is provided with：Supporting plate is (for example, the lower raft of sheet metal or keyboard）It is arranged on the keycap above supporting plate, mutually link and installed in a pair of plastic supporting pieces for being guided towards vertical direction and supporting keycap of the top of supporting plate, corresponding to the switching mechanism of the contact portion of the elevating movement opening and closing circuit of keycap, it is ensured that keycap can recover to high-order elastic construction（Generally rubber bullet circle）.Mutually linked by a pair of plastic rod parts, it is ensured that the posture that keycap can remain parallel to supporting plate relative to supporting plate towards substantial orthogonality direction carries out elevating movement.The operating characteristic of stroking of key switch can be by the path increment of the lifting action of the keycap, the rigidity of plastic rod part, plastic rod part and keycap fit clearance, and with the influence of the operating characteristic of stroking of so-called sensation of stroking in lifting action.
Thin plastic X support structure apparatus is generally used in the portable electron devices such as existing notebook type or palmtop computer.Include keycap 1, elastomer 11, thin film switch piece 12, the supporting plate 15 for having auxiliary section, a pair of support members for having support member auxiliary section, i.e. the first support member 4 and the second support member 8 referring to the bond structure device of the existing keyboard of Fig. 1, Fig. 2.Auxiliary section of the plastic supporting pieces by support member auxiliary section respectively with keycap 1, supporting plate 15 rotates or is slidably connected.From the side in X shapes install plastic supporting pieces by near middle each other power transmission constitute synchronous interaction supporting construction, to ensure keycap 1 parallel to the elevating movement of supporting plate 15..
Fitted shaft 9 is constituted under the support member of fitted shaft 6 and second on fitted shaft 7 under fitted shaft 10, the first support member on the first support member, the second support member respectively for the auxiliary section of support member.The near middle of the wherein pitman arm of the first support member 4 forms middle pivot 5, the near middle of the pitman arm of second support member 8 forms pivot hole 5a, wherein middle pivot 5 and pivot hole 5a formation is rotatably assorted, so constitute ensure keycap 1 can parallel to the elevating movement of supporting plate 15 synchronous interaction supporting construction.For the ease of installing, first support member pivot hole 5a many be all provided with mounting groove 19 as depicted.
The auxiliary section of supporting plate 15 is made up of support plate rotation section 13 and support plate sliding part 14, and to ensure that support member does not come off from the auxiliary section of supporting plate, supporting plate positive stop lug boss 16 is typically provided in supporting plate 15.The auxiliary section of supporting plate 15 is slidably matched or is rotatably assorted with the formation of fitted shaft 9 under fitted shaft 7, the second support member under the first support member respectively.The auxiliary section of keycap 1 is slidably matched or is rotatably assorted with the formation of fitted shaft 6 on fitted shaft 10 on the first support member, the second support member respectively.
Elastomer 11 is fixed on the upper surface of thin film switch piece 12 and corresponding with the interior concave surface of keycap 1, and the support plate rotation section 13 and support plate sliding part 14 that thin film switch piece 12 is fixed in the upper surface of supporting plate 15, supporting plate 15 are passed through
Corresponding through hole on thin film switch piece 12, and near the top of the upper surface of thin film switch piece 12.
Referring to Figure 45, Figure 46, Figure 47 to realize preferably feel, prior art is used mostly：Support member rotates one using one with keycap 1 and is slidably matched；Support member rotates one using one with supporting plate 15 and is slidably matched, when keycap 1 is installed, and the first support member, the second support member are in limit inferior position, referring to Figure 47.
During installation, keycap 1 moves down extruding elastomer 11 first, the lower end of elastomer 11 is fixedly mounted on the upper surface of thin film switch piece 12, deform elastomer 11, during to limit inferior position, the upper auxiliary section of one of support member is first allowed to enter an auxiliary section of keycap 1, again by another auxiliary section of the upper auxiliary section force fit keycap 1 of another support member, keycap 1 is not parallel in installation process and supporting plate 15, to ensure the reliability installed, must assure that during design the upper auxiliary section of support member by interference extrusion completely into the space of the auxiliary section of keycap 1 after, keycap 1 can also move down the 2mm of 0. lmm -0. idle stroke, because considering feel and thin type structure design, idle stroke can not design too big, could be with the upper surface of thin film switch piece 12 installed in supporting plate 15, in whole installation process, there is the displacement of horizontal direction in the upper end of elastomer 11, the phenomenon for being fixedly connected with degumming and separating of elastomer 11 and thin film switch piece 12, simultaneously because the auxiliary section of supporting plate 15, the lower auxiliary section mismachining tolerance of keycap 1, when keycap 1 and thin film switch 12 upper surface of piece, occur an other support member upper auxiliary section can not completely into the adapted space of the auxiliary section of keycap 1 situation, batch installs keycap 1 and cannot ensure reliable installation.Cause batch to make installation keycap 1 is difficult to become big automatically, qualification rate can not reach requirement, often need the keycap that will do not installed reliably to install by hand.
The keycap 1 of this structure, generally using a keycap rotation section 2, a keycap sliding part 3.During installation, the support member being slidably matched with keycap formation is first installed.Then the support member that is rotatably assorted will be formed with keycap using the deformation of keycap rotation section 2 to be installed on keycap 1.
Because the attachment structure of keycap rotation section 2 is each perpendicular to the plate face of keycap 1, length is not typically long, and no more than 1. 5mm, auxiliary section on support member is installed in keycap rotation section 2, and the attachment structure deflection of keycap rotation section 2 cannot be too big.On the other hand, in order to ensure that auxiliary section is not fallen off on support member, it is necessary that the deflection of keycap rotation section 2 can not be too small when installing, so often occurring the situation of the fracture of keycap rotation section 2 in installation process.Typically now using improve production precision, and using some higher material of intensity to solve this contradiction the problem of.But this will undoubtedly increase production cost, also it is unfavorable for realizing multiple installation.
In installation process, the support member being slidably matched with keycap formation is first installed, then the support member being rotatably assorted with keycap formation is installed, is divided to two installations, influences installation effectiveness, also increase installation difficulty.
When installing keycap 1 now, support member is approximately to lie low in supporting plate 15, and when installing keycap, support member stress is perpendicular to support member plate face, easily causes the flexural deformation of support member, influences handfeel of keys.The uniformity of keyboard height is particularly influenceed, causes keyboard not attractive in appearance enough.
