Specific embodiment
The following further describes the present invention in detail with reference to the accompanying drawings and specific embodiments.
A kind of stroke detection as shown in Fig. 1-17 and the device for judging the direction of motion, in the defeated of electrically driven curtain output mechanism
Corresponding on shaft 5 to be equipped with stroke detection module, the stroke detection module includes grating sensor 1 and grating disc 2, described
Grating disc 2 is mounted on output shaft 5 and rotates synchronously with output shaft 5；The installation corresponding with grating disc 2 of grating sensor 1, institute
Stating grating disc 2 is circular turntable, opens up spaced through-hole in the grating disc 2.
As shown in Figure 1-3, stroke detection module is used to detect electrically driven curtain movement travel and judges its direction of motion, individually
The detection structure of grating sensor 1 only has the function of detection stroke, cannot but detect the positive and negative rotation of grating disc 2, so in order to
Realize the function that curtain will be automatically moved along the direction pulled when pulling dynamic curtain, it is necessary to select two grating sensors
1 detection structure is with the design for unifying an output shaft 5, and in manual pull, corresponding synchronizing wheel is rotated and driven electrically driven curtain
Grating disc 2 rotates, and the rotation direction of grating disc 2 is just detected by the signal of two grating sensors 1 at this time, to identify
Pull the direction of dynamic curtain.It is designed in this way, as shown in figures 4-17, can both realize the detection of electrically driven curtain stroke, while can also be with
Detect the direction that grating disc 2 rotates.
Wherein, as shown in Fig. 4-7 and Figure 11, the grating disc 2 is 2, is mounted on same root up and down with the structure of stratiform
On output shaft 5, and two grating discs 2 are designed as blocking 2 through-hole of half-space grating disc up and down；The grating sensor 1 be 2, two
The position that a grating sensor 1 respectively corresponds grating disc 2 is staggeredly arranged in 5 two sides of output shaft, one of grating sensing up and down
When the inductive head of device 1 is in the through-hole that will enter its corresponding grating disc 2, the inductive head of another grating sensor 1
Positioned at the position of its non-through bore region half of corresponding grating disc 2.
1 testing agency of grating sensor design is there are two grating disc 2, and two 2 layered distributions of grating disc, upper lower pellet
2 through-hole of half-space grating disc, when the inductive head of a grating sensor 1 will just enter 2 through-hole of grating disc, another grating sensing
1 inductive head of device just in the position of the non-through bore region half of grating disc 2, so could more accurately detect grating disc 2 just
Reversion, purpose is exactly to realize being staggered for grating signal, i.e., first recording first is "ON", after record another and be similarly "ON"
When, then it can detect that the positive and negative rotation of grating turntable, two grating discs 2 be designed in this scheme, it is more effective to guarantee grating disc 2
Structure arrangement and grating sensor 1 installation, be easily installed, this scheme be optimal case.
Wherein, as shown in Fig. 8-9 and Figure 11, the grating sensor 1 is 2, and two grating sensors 1 are arranged symmetrically in
The two sides of one grating disc 2, when the inductive head of one of grating sensor 1 is in the through-hole that will enter grating disc 2,
The inductive head of another grating sensor 1 is located at the position of the non-through bore region half of grating disc 2.A light is only designed in this programme
Grid disk 2, and being arranged symmetrically for two grating sensors 1, also for being staggered for grating square-wave signal is realized, that is, realize detection
The positive and negative rotation of grating disc 2, when the inductive head of a grating sensor 1 will just enter 2 through-hole of grating disc, another grating sensing
Device 1 just in the position of the non-through bore region half of grating disc 2, so could more accurately detect the positive and negative rotation of grating disc 2；For
Reach above-mentioned detection function, the installation of two grating sensors 1 needs certain differential seat angle, therefore two in this programme
A grating sensor 1 is relatively difficult during installation, need to can just meet installation requirement by repeatedly subtle angle adjustment.
Wherein, as shown in figs. 10-11, the grating sensor 1 is 2, and two grating sensors 1 are arranged side by side in one
The same side of grating disc 2, when the inductive head of one of grating sensor 1 is in the through-hole that will enter grating disc 2, separately
The inductive head of one grating sensor 1 is located at the position of the non-through bore region half of grating disc 2.Equally, one is designed in this programme
Grating disc 2, and grating sensor 1 is arranged side by side also for being staggered for grating square-wave signal is realized, detects grating disc 2 to realize
Positive and negative rotation requirement；In this detection design scheme, the aperture of 2 through-hole of grating disc requires to be incuded according to grating sensor 1
The distance of head is opened up, but since the distance of grating sensor 1 side by side there are certain requirements, so to detect stroke in high precision
The through-hole of biggish turntable and comparatively dense is then needed to realize, it is bigger than normal so as to cause overall structure.
It wherein, as shown in figs. 12-14, further include having hollow type encoder 3, the hollow type encoder 3 includes fixation
Part 31 and revolving part 32；The revolving part 32 is rotated synchronously with the cooperation of grating disc 2, and it is defeated that the fixing piece 31 is fixed on electrically driven curtain
The corresponding position of mechanism shell out is achieved in the relative motion of revolving part 32 Yu fixing piece 31, the detection of hollow type encoder 3
Principle is as the testing principle of Double-grating sensor 1, again by being staggered for realization 1 two square-wave signals of grating sensor
It opens, to realize the direction of motion of detection grating disc 2.
It wherein, as shown in figs. 16-17, further include having knob encoder 4, the knob encoder 4 and output shaft 5
The rotary motion of grating disc 2, is transferred to knob encoder by gear engagement, similarly, realizes 1 two square-wave signals of grating sensor
Be staggered, with realize detection grating disc 2 the direction of motion.
Wherein, depending on the required precision that the quantity of 2 through-hole of grating disc detects as needed, required precision is higher, leads to
The interval in hole is smaller, and quantity is more.
The implementation of the present invention is not limited to this, and above content according to the invention is known using the ordinary skill of this field
Knowledge and customary means, under the premise of not departing from above-mentioned basic fundamental thought of the invention, the present invention can also make other a variety of shapes
Modification, replacement or the combination of formula, all fall within rights protection scope of the present invention.
