Abstract
The utility model provides a button system which substantially includes a switch and a button, wherein the button includes a pressing part for accepting the pressure force, a driving part for driving the switches and a connection part for connecting the pressing part and the driving part. The button also includes a flexible supporting part. As the utility model of a new button system is provided with the flexible supporting part, the button is stressed uniformly during the journey and has good rebound elasticity and had feeling.
Description
[technical field]
The present invention relates to a kind of key system, refer to a kind of key system that can be used on the electronic equipment especially.
[background technology]
Usually, button is used for the start switch, is the requisite elements of electronic equipment such as computer, household electrical appliances.
With reference to shown in Figure 1, a kind of common existing button 100 comprises portion of exerting pressure 101 and Actuator Division 102, and the portion 101 that wherein exerts pressure accepts pressing force, impels Actuator Division 102 to switch 200 application of forces, thereby reaches the effect of control switch 200.Should existing button 100 be eccentric structures, the center of promptly exert pressure portion 101 and Actuator Division 102 be in different straight lines, and therefore, external force is not to the application point of 102 pairs of switches 200 of application point and Actuator Division of the portion of exerting pressure 101 not point-blank.When being subjected to pressing force, existing button 100 often tilts and is movement in a curve, rather than desirable rectilinear motion.Yet, the movement in a curve of this inclination often cause button card key and can't resilience, problem such as keys deactivation and feel difference.
For addressing the above problem, 102 places are provided with lead 103 to a kind of improvement button 100 ' as shown in Figure 2 in the Actuator Division, are used to impose restrictions on the inclination of button 100 '.Yet in the process that restriction button 100 ' tilts, lead 103 produces friction with Actuator Division 102 inevitably, has increased the stroke of button 100 ', thereby has reduced the service speed and the sensitivity of button 100 '.
Therefore, be necessary to provide a kind of new button to solve the existing in prior technology defective.
[summary of the invention]
The object of the present invention is to provide a kind of key system, it is simple in structure, have good resilience and feel.
For achieving the above object, the present invention adopts following technical scheme: key system of the present invention mainly includes: switch and button.Wherein button comprises the press section that is used to accept pressing force, the actuation part that is used for actuation switch and the connecting portion that connects press section and actuation part.Button also comprises the rubber-like support portion.
Compared to prior art, the button of key system of the present invention is provided with the rubber-like support portion, thereby makes button stress equalization and make button have good resilience and feel in stroke.

Fig. 2 is the structural representation of another kind of existing button.
Fig. 3 is the structural representation of key system of the present invention.
[embodiment]
Please refer to shown in Figure 3ly, the key system of preferred embodiment of the present invention comprises: button 10, switch 20 and panel 30.Button 10 comprise level connecting portion 12, be arranged on the press section 11 of connecting portion 12 tops, from actuation part 13 and rubber-like support portion that connecting portion 12 protrudes out downwards.The support portion comprises support column 14 and the resilient portion 15 that cooperates with support column 14.Support column 14 and actuation part 13 are separately positioned on the opposite end of connecting portion 12.In this preferred embodiment, support column 14 is cylindrical, and resilient portion 15 can be a spring, also can be rubber-like rubber ring or other flexible members.The length of resilient portion 15 is greater than support column 14.Panel 30 can be that the plastic rubber panel below the button 10 can be selected other single part, in order to support the support portion.
When pushing button 10 the time, clockwise pressing force F1 is accepted in press section 11, impels actuation part 13 to inspire switch 20 to switch 20 application of forces, drives support column 14 and resilient portion 15 simultaneously to panel 30 displacements.Support column 14 arrives the range of the distance of panel 30 less than button 10.Stressed switch 20 applies anticlockwise reaction force F2 to actuation part 13, thereby resilient portion 15 is pressed to panel 30 and is subjected to the anticlockwise reaction force F3 that panel 30 applies.
The a certain moment that is in operation with button 10 is an example, and the stressed and moment of button is seen Fig. 3, and wherein F1 is the suffered extraneous pressing force of button 10, and F2 is the active force of switch to button 10, and F3 is the active force of 15 pairs of buttons 10 of resilient portion; L2 is the arm of force of F2 with respect to button 10 centers, and L3 is the arm of force at the relative button of F3 10 centers.By as can be known above-mentioned, F2, L2 are definite values, and L3 can select according to space structure, if this moment the choose reasonable spring elastic force F3, just can satisfy following formula:
F1＝F2+F3
F2×L2-F3×L3＝0
This moment button clockwise moment and anticlockwise moment equal and opposite in direction, moment obtains balance, according to mechanics law, button 10 will keep balance, that is to say: button can obtain desirable rectilinear motion in this moment.
In fact, button be pressed and the whole process returned in, button 10 all can obtain the rectilinear motion of near ideal.Reason is: according to the internal structure of switch 20, F2 can change from small to big then from large to small gradually, and the performance of resilient portion 15 has determined the elastic force F3 of resilient portion 15 also to have same change procedure, thereby makes the moment of button 10 keep approximate dynamic equilibrium.
By above analysis, can reach a conclusion, the stretch parameter of choose reasonable resilient portion 15, in the stroke of whole button 10, button 10 can obtain to approach desirable rectilinear motion.
Because the button 10 of key system of the present invention is provided with the rubber-like support portion, make button 10 stress equalization and make button have good resilience and feel in stroke.
