Abstract
The invention discloses a device on electrical equipment for quickly replacing buttons with different motion modes. The button motion modes comprise a linear motion mode and a rotary motion mode, and buttons can be divided into a straight moving button and a rotary button. The device provided by the invention is composed of a button installation module, the buttons, a reset torsional spring, a pin shaft and the like, wherein the button installation module is a component of a surface cover on the electrical equipment, achieves the purpose of installing the two kinds of buttons of different structural types on one surface cover, and realizes the effects of being diversified in operation and reducing surface cover cost. Problems of structural design of the two kinds of buttons and critical dimensions such as the position of a pin shaft hole in the surface cover are effectively solved according to a button functional dimension design formula disclosed by the invention. The straight moving button and the rotary button adopt the same reset torsional spring and the same pin shaft, so that the effect of replacing the buttons with different motion modes quickly without replacing other components is achieved. During the structural design process of the straight moving button and the rotary button, the problems such as guidance, positioning and displacement in the motion process and error-assembly in the assembling process of the buttons are solved, thereby ensuring stability and accuracy of the button motion process.

On mask is installed.
Button motion mode mainly has two kinds：Linear motion and rotary motion, for solving to install two kinds on same minor face cover
The button of Different Exercise Mode, the mentality of designing that the present invention provides：Component function demand first according to button triggering, determination is pressed
The output quantity of button, i.e. the corner of the rectilinear path of direct acting button or rotary knob, then determine the key function size of two kinds of buttons
Relation, determine the functional dimension of another kind of button according to a kind of functional dimension of button, then module, straight installed by design button
The structures such as dynamic button, rotary knob, torsion spring, axle.
1. the functional dimension design of button：
The functional dimension of button has：The boss height of direct acting button, the stroke of direct acting button, the boss center of direct acting button
Line is to the distance of bearing pin centerline hole, the rotational angle of rotary knob, the boss height of rotary knob, the boss of rotary knob
Heart line to bearing pin centerline hole distance.Wherein the stroke of direct acting button and the rotational angle of rotary knob are tied by trigger unit
Structure affects, generally as the primary data of design.
Because direct acting button and rotary knob must all meet the triggering requirement of miscellaneous part, following relation can be obtained
Formula：
H'=H- (L*tan θ-S) (1)
L'=L/cos θ (2)
In formula, S is the rectilinear path of direct acting button, and typically no less than 2mm, L are in the first cylindrical boss of direct acting button
Heart line to the bearing pin centerline hole of mask distance, H be direct acting button on the first cylindrical boss height；H' is rotary knob
The height of upper second cylindrical boss, L' is the pin that on rotary knob, the second cylindrical cylindrical boss center line extremely installs mask
The distance of axis hole center line, θ is the design rotational angle of rotary knob, typically no less than 10 °.
In Fig. 1, geometrical model shows the top center of rotary knob and pin shaft hole center on same vertical line, in order to increase
Plus the effective range of rotary knob；Meanwhile, on direct acting button, the height of the first cylindrical boss is slightly above on rotary knob
Second cylindrical boss, because longer with respect to the EFFECTIVE RANGE of rotary knob direct acting button, and is conducive to bearing pin
Move behind the center in hole.
2. module installed by button：The appearance profile of button typically adopts rectangular configuration, the present invention pressing using rectangular profile
Button, its vertical direction is long side, and the long side of rectangle is more than minor face and is not less than 1.5mm, it is to avoid the mistake dress of assembling process, such as schemes
Rectangular channel 1 in 2.Two semi-circular recesses of design have excellent guidance quality, technique as the guide rail of direct acting button, circular configuration
Property, it is to ensure that the button only one of which free degree using two separate semi-circular recesses, that is, moves axially so, prevent axle
To rotation, semi-circular groove 2 in such as Fig. 2.The position of pin shaft hole determines in following press-button structure design.
3. direct acting button：In Fig. 3, the first cylindrical boss 5 is as the key feature of button, for triggering miscellaneous part, directly
Dynamic button is generally placed upon in the symmetrical centre of button, and the present invention, using the structure of design placed in the middle, therefore combines formula (2) and engineering
Experience is to determine the position in mask upper pin hole.The top of the first cylindrical boss and the idle stroke between part that is triggered are general not
Less than 1mm, therefore in formula (1), the first cylinder boss height H of direct acting button determines.With two semicircle boss and installation
Semi-circular recesses cooperation on mask, has the functions such as the positioning of guiding, slip, reset state, semicircle boss 6 in such as Fig. 3.
For preventing button on face shield assembly from coming off, button designs circular hole feature first circular hole 7 (circular hole 7 in as Fig. 3),
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 is permissible with the height of direct acting button according to formula (1)
Determine, its position is determined by formula (2), one rectangular boss of design solves the positioning of reset state (as rectangular boss in Fig. 4
9).In Fig. 4, button support hole 10 coordinates it is ensured that rotary knob rotates around the pin shaft hole of mask with bearing pin, the end of button support hole
Should there is small gap between face and installation mask upper wall, prevent button from course of action, rocking of left and right directions occurring.Rotation is pressed
Button identical with direct acting button with the contact characteristic of reduction torsion spring (as circular hole 11 in Fig. 4).
5. reduction torsion spring and bearing pin：One haptic element of reduction torsion spring is kirby feature, and another haptic element is linear pattern, bearing pin
Two ends carry jump-ring slot, are used for preventing axial motion.
6. button installation steps：
Direct acting button：Direct acting button upper half round boss is put into the square installing mask along the semi-circular groove installing mask
In shape groove, the round hook-type haptic element of reduction torsion spring is first put in the assembling circular hole of button, and then torsion spring passes through with bearing pin and installs
Pin shaft hole on mask, another pin of torsion spring rides on mask one wall, jump ring on bearing pin two ends, as Fig. 5 (a) after installation,
Promote such as Fig. 5 (b) after 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, and bearing pin is passed through from one end
The supported hole of button, then passes through reduction torsion spring, is then passed through another supported hole of button, and another pin of reduction torsion spring rides over installation
On mask one wall, as Fig. 6 (a) after installation, promote such as Fig. 6 (b) after direct acting button actions.
7. button replacing options：
Direct acting button is replaced with rotary knob：Lay down one end jump ring of bearing pin, extract bearing pin, take off direct acting button, according to
The installation steps assembling rotary knob of direct acting button.
Rotary knob is replaced with direct acting button：Lay down one end jump ring of bearing pin, extract bearing pin, take off rotary knob, according to
The installation steps assembling direct acting button of direct acting button.Renewal process does not change other parts it is achieved that quick-replaceable.
