Button motion mode mainly contains two kinds: rectilinear motion and rotary motion, for solving the button same minor face cover being installed two kinds of Different Exercise Mode, mentality of designing provided by the invention: first according to the component function demand that button triggers, the output variable of confirming button, the i.e. rectilinear path of direct acting button or the corner of rotary knob, determine the relation of the key function size of two kinds of buttons again, determine the functional dimension of another kind of button according to a kind of functional dimension of button, then design the structures such as button installation module, direct acting button, rotary knob, torsion spring, axle.
1. the functional dimension design of button:
The functional dimension of button has: the boss center line of the boss height of direct acting button, the stroke of direct acting button, direct acting button is to the rotational angle of the distance of pin shaft hole center line, rotary knob, the boss height of rotary knob, the boss center line of rotary knob to the distance of pin shaft hole center line.Wherein the stroke of direct acting button and the rotational angle of rotary knob are subject to the structure influence of trigger unit, generally as the primary data of design.
Because direct acting button and rotary knob all must meet the triggering requirement of miscellaneous part, following relational expression can be obtained:
H'＝H-(L*tanθ-S)(1)
L'＝L/cosθ(2)
In formula, S is the rectilinear path of direct acting button, is generally not less than 2mm, and L is the distance of the first cylindrical boss center line to the pin shaft hole center line of face shield of direct acting button, and H is the height of the first cylindrical boss on direct acting button; H' is the height of the second cylindrical boss on rotary knob, and L' is that on rotary knob, the second cylindrical cylindrical boss center line is to the distance of the pin shaft hole center line of installation face shield, and θ is the design rotational angle of rotary knob, is generally not less than 10 °.
In Fig. 1, geometrical model shows that the center, top of rotary knob and pin shaft hole center are on same vertical line, in order to increase the effective range of rotary knob; Meanwhile, on direct acting button, the height of the first cylindrical boss is a little more than the second cylindrical boss on rotary knob, because longer relative to the EFFECTIVE RANGE of rotary knob direct acting button, and moves after being conducive to the center by pin shaft hole.
2. button installation module: the appearance profile of button generally adopts rectangular configuration, the utility model adopts the button of rectangular profile, and its vertical direction is long limit, and the long limit of rectangle is greater than minor face is not less than 1.5mm, the mistake of assembling process is avoided to fill, as rectangular channel in Fig. 21.Design the guide rail of two semi-circular recesses as direct acting button, circular configuration has excellent guidance quality, manufacturability, uses two semi-circular recesses separated to be to ensure that button only has one degree of freedom, namely axially moving, prevent axial-rotation, as semi-circular groove in Fig. 22.Determine in the press-button structure design below of the position of pin shaft hole.
3. direct acting button: in Fig. 3, the first cylindrical boss 5 is as the key feature of button, for triggering miscellaneous part, direct acting button is generally placed in the symmetrical centre of button, the utility model adopts the structure of design placed in the middle, therefore in conjunction with formula (2) and engineering experience to determine the position in face shield upper pin hole.Top and the idle stroke between parts that is triggered of the first cylindrical boss are generally not less than 1mm, and therefore in formula (1), the first cylinder boss height H of direct acting button is determined.Coordinate with the semi-circular recesses installed on face shield with two semicircle boss, there is the function such as location of guiding, slip, reset mode, as boss 6 semicircle in Fig. 3.For preventing button on face shield assembly from coming off, button designs a circular hole feature---the first circular hole 7 (as circular hole in Fig. 3 7), for assembling the haptic element of the kirby of reduction torsion spring.
4. rotary knob: in Fig. 4, the height of the second cylindrical boss 8 can be determined according to the height of formula (1) with direct acting button, its position is determined by formula (2), designs the location (as rectangular boss in Fig. 4 9) that a rectangular boss solves reset mode.In Fig. 4, button support hole 10 coordinates with bearing pin, ensures that rotary knob rotates around the pin shaft hole of face shield, should have comparatively small―gap suture, prevent button from occurring rocking of left and right directions at course of action between the end face of button support hole and installation face shield upper wall.Rotary knob identical with direct acting button with the contact characteristic of reduction torsion spring (as circular hole in Fig. 4 11).
5. reduction torsion spring and bearing pin: reduction torsion spring haptic element is kirby feature, and another haptic element is linear pattern, bearing pin two ends with jump-ring slot, for preventing axial motion.
6. button installation steps:
Direct acting button: first round boss of direct acting button is put into the rectangular channel installing face shield along the semi-circular groove of installing face shield, the round hook-type haptic element of reduction torsion spring is first put in the assembling circular hole of button, then torsion spring passes the pin shaft hole installed on face shield with bearing pin, another pin of torsion spring rides on face shield one wall, jump ring on bearing pin two ends, as Fig. 5 (a) after installation, as Fig. 5 (b) after promotion direct acting button actions.
Rotary knob: the round hook-type haptic element of reduction torsion spring is first put in the assembling circular hole of button, bearing pin is passed the supported hole of button from one end, then through reduction torsion spring, again through another supported hole of button, another pin of reduction torsion spring rides over to be installed on face shield one wall, as Fig. 6 (a) after installation, as Fig. 6 (b) after promotion direct acting button actions.
7. button replacing options:
Direct acting button is replaced with rotary knob: one end jump ring laying down bearing pin, extracts bearing pin, takes off direct acting button, according to the installation steps assembling rotary knob of direct acting button.
Rotary knob is replaced with direct acting button: one end jump ring laying down bearing pin, extracts bearing pin, takes off rotary knob, according to the installation steps assembling direct acting button of direct acting button.Renewal process does not change other parts, achieves quick-replaceable.
