It repeats again.
Resistance is provided to the rotation of idler wheel for how the present embodiment passes through magnetic damping force, is described as follows:
When idler wheel 111 rotates, multiple second magnetic substances 13 on the first plane of rotation 1111 will receive turning for idler wheel 111
It moves traction and sequentially intersects and interlock with the first magnetic substance 12, since the second magnetic substance 13 and the first magnetic substance 12 to each other can magnetic
Property attract, thus the first magnetic damping force can be generated between the second magnetic substance 13 and the first magnetic substance 12, the first magnetic damping force
Can decay the rotational energy of idler wheel 111, and provide resistance to the rotation of idler wheel 111.The peak value of first magnetic damping force i.e.
The maximum value and the valley i.e. minimum value of the first magnetic damping force of one magnetic damping force, can be respectively in the second magnetic substance 13 and first
Magnetic substance 12 intersection with staggeredly when generate.The peak value of first magnetic damping force can be in every one second magnetic substance 13 and the first magnetic substance
It is generated when 12 intersection, the valley of the first magnetic damping force can be produced when every one second magnetic substance 13 interlocks with the first magnetic substance 12
It is raw.Thus, the every rotation first angle θ of idler wheel 1111When, the second magnetic substance 13 and the first magnetic substance 12 can complete the friendship in a stage
Can and staggeredly, and the first magnetic damping force is allowed to generate the variation in a stage between peak value and valley, due to the first magnetic damping force
Can decay the rotational energy of idler wheel 111, thus variation of the first magnetic damping force between peak value and valley, can all make idler wheel
The Resistance Value being subjected to when 111 rotation changes correspondingly, and the Resistance Value of the change will form the sense of touch of user, in this way, using
Person can be current by touch feeling idler wheel rotational angle.
Similarly, when idler wheel 111 rotates, multiple 4th magnetic substances 19 on the second plane of rotation 1113 will receive idler wheel
111 rotation traction and sequentially intersect with third magnetic substance 18 and staggeredly, due to the 4th magnetic substance 19 and third magnetic substance 18 that
Around here can magnetic attraction, thus the second magnetic damping force is generated between the 4th magnetic substance 19 and third magnetic substance 18, the second magnetic
Damping force can also decay the rotational energy of idler wheel 111, and provide resistance to the rotation of idler wheel 111.Second magnetic damping force
The peak value i.e. maximum value of the second magnetic damping force and the valley i.e. minimum value of the second magnetic damping force, can be respectively in the 4th magnetic substance
19 intersected with third magnetic substance 18 with staggeredly when generate.The peak value of second magnetic damping force can be in every 1 the 4th magnetic substance 19 and
Three magnetic substances 18 generate when intersecting, and the valley of the second magnetic damping force can be handed in every one the 4th magnetic substance 19 with third magnetic substance 18
It staggers the time generation.Thus, the every rotation second angle θ of idler wheel 1112When, the 4th magnetic substance 19 can complete single order with third magnetic substance 18
The intersection of section and allows the second magnetic damping force to generate the variation in a stage between peak value and valley with staggeredly, due to the second magnetic
Damping force can decay the rotational energy of idler wheel 111, thus variation of the second magnetic damping force between peak value and valley, can all make
The Resistance Value that idler wheel 111 is subjected to when rotating changes correspondingly, and the Resistance Value of the change will form the sense of touch of user, and allowing makes
User can easily pass through the actual rotational angle of touch feeling idler wheel.
It should be noted that in this present embodiment, it can be by reduction first angle θ1, and reach and improve the first magnetic damping force
The frequency changed between peak value and valley, to promote the sensitivity that user can be allowed to pass through touch feeling idler wheel rotational angle, because
This, the quantity for the second magnetic substance 13 that ring is set on the first plane of rotation 1111 can cooperate the sensitivity of adjustment idler wheel and increase and decrease, not
It is limited with content disclosed by Fig. 1.It similarly, can also be by reduction second angle θ2, and reach and improve the second magnetic damping force
The frequency changed between peak value and valley, to promote the sensitivity that user can be allowed to pass through touch feeling idler wheel rotational angle, because
This, second angle θ2It might not substantially identical first angle θ1, and the 4th magnetic substance 19 that ring is set on the second plane of rotation 1112
Quantity can also cooperate the sensitivity of adjustment idler wheel and increase and decrease, and be not limited with content disclosed by Fig. 2.
In this present embodiment, rotation sensing unit 16 is grating sensing device, the every rotation of idler wheel 111 and first angle θ1Essence
Identical third angle θ3When, optical signal conveyer 161 is blocked and one of multiple unthreaded holes 1114 by the light of idler wheel 111 itself
Light penetrate variation between the two formed optical signal send to rotation sensing unit 16, and then provide rotation sensing unit 16 sense
The current rotational angle of idler wheel 111.As shown in figure 3, processor 17 enables rotation sensing unit 16 execute sensing operation, and receives and turn
The sensing result of dynamic sensing unit 16, it is for processing and obtain the current rotational angle of idler wheel 111, and send about idler wheel 111
For the signal of current operation angle to computer, the rotational angle for keeping computer current according to idler wheel executes operation.
Though should be noted that third angle θ in the present embodiment3It is substantially identical in first angle θ1, but in addition can be by reduction
Third angle θ3, and reach and improve the frequency that optical signal conveyer 161 transmits optical signal to rotation sense side unit 16, turned with being promoted
Dynamic sensing unit 16 senses the sensitivity of 111 rotational angle of idler wheel, therefore, third angle θ3It is not necessarily to substantially identical first
Angle, θ1, also therefore, the quantity for the unthreaded hole 1114 that ring is set on idler wheel 111 should not be limited with the content disclosed by Fig. 1.
