Brief description
Fig. 1 is the structural representation of an embodiment of the present invention；
Fig. 2 is the tangent plane structural representation of screw of the present invention, elastic component and screw.
Detailed description of the invention
By describing technology contents, the structural feature of the present invention in detail, being realized purpose and effect, below in conjunction with embodiment
And coordinate accompanying drawing to be explained in detail.
Referring to Fig. 1 and Fig. 2, the present invention provides a kind of adjustable acceleration transducer of precision, including light shelter is the 1st, horizontal
To light path 2 and longitudinal light path 3, lateral light paths 2 and longitudinal light path 3 square crossing form light face, lateral light paths 2 and longitudinal light path 3
All including the parallel and equidistant light path of two or more, it is adjacent that the adjacent optical path spacing in lateral light paths is equal in longitudinal light path
Light path spacing, the diameter of light shelter is more than the spacing of adjacent optical path, and light path includes luminescence unit and corresponding photosensitive unit,
Photosensitive unit is for detecting the circumstance of occlusion of light path, and described photosensitive unit is used for transmitting acceleration information.Described smooth shelter leads to
Crossing elastic component 4 to be connected with four sides of acceleration transducer, one end of elastic component is fixed on light shelter, elastic component 4 another
One end connects with screw 5 ball, and screw is arranged in the screw 6 of acceleration transducer side.Elastic component should be that elastic force is uniform, when
Light shelter is at Guang Mian center, and now in all directions, acceleration should be zero.Wherein, screw can be arranged on acceleration transducer
Four sides in the center of every one side.Elastic component can be rubber band or spring etc..By adjusting screw in screw
The degree of depth, can regulate the elastic force of elastic component, and as screwed out screw, then elastic force becomes big, and under same acceleration, light shelter moves
Distance shortens, thus under same testing conditions, corresponding accekeration can become big, so that acceleration transducer can produce
Raw different acceleration precision.I.e. by screwing screw or unscrew screw, precision can be changed, easily.
Such as Fig. 1, acceleration transducer includes longitudinal direction (Y and Y ' direction) light path four and horizontal (X and X ' direction) light path
Four, four lateral light paths equidistantly and are parallel to each other, and four longitudinal light paths are parallel to each other.Lateral light paths four is respectively A and A '
To D and D ', longitudinal light path four is respectively E and E ' and arrives H and H ', and lateral light paths and longitudinal light path are in same level, i.e.
Light face.Acceleration transducer horizontal and vertical all there is no acceleration when, light shelter is placed in position, middle, light face.This time
Shelter can block four light paths near Guang Mian center, and photosensitive unit can send signal light path being detected, by this
Signal is not it is known that horizontal and vertical all have acceleration.And when horizontal (such as X-direction) has acceleration, light shelter can be to X '
Move in direction, then light shelter can block the light path of GG ' or HH ', then the photosensitive unit of GG ' or HH ' can export and be not detected by
The signal of light, such that it is able to know that acceleration transducer is in X-direction acceleration.With the increase of acceleration, light shelter is also
Further from center, thus farther light path can be blocked, from the light path farther from Guang Mian center it is known that acceleration is bigger
?.I.e. when horizontal and vertical all there is no acceleration when, light shelter is in Guang Mian center, the increasing of acceleration on different directions
Adding, light shelter also can increase toward acceleration opposite direction away from the distance at Guang Mian center, thus blocks the light path at edge, by inspection
Survey the light path at edge it is known that the situation of acceleration.
In certain embodiments, described luminescence unit is the light emitting diode of relative power saving.Described photosensitive unit is low one-tenth
This photo resistance.
In certain embodiments, in order to avoid the interference of other light, luminescence unit has glow frequency, described photosensitive unit
Described glow frequency then output detections signal detected.The i.e. only light of the glow frequency of response, photosensitive unit just can export inspection
Survey signal, otherwise, not output detections signal.This glow frequency can be 38KHZ.38KHZ is the luminous frequency of IR remote controller
Rate, relatively common, cheap.
The foregoing is only embodiments of the invention, not thereby limit the scope of patent protection of the present invention, every utilization
Equivalent structure or equivalence flow process that description of the invention and accompanying drawing content are made convert, or it is related to be directly or indirectly used in other
Technical field, all in like manner include in the scope of patent protection of the present invention.
