Fig. 1 is the structural representation of an embodiment of the present invention；
Fig. 2 is the structural representation of another embodiment of the present invention；
Fig. 3 is the structural representation of another embodiment of the present invention.
Detailed description of the invention
By describing the technology contents of the present invention, structural feature in detail, being realized purpose and effect, below tie
Close embodiment and coordinate accompanying drawing to be explained in detail.
Referring to Fig. 1 to Fig. 3, the present invention provides a kind of acceleration transducer based on photoconductive resistance, including
Light shelter 1, lateral light paths 2 and longitudinal light path 3, lateral light paths 2 and longitudinal light path 3 square crossing shape
Becoming bright finish, lateral light paths 2 and longitudinal light path 3 all to include plural light path, light path includes to be sent out
Light unit and corresponding photosensitive unit, photosensitive unit is for detecting the circumstance of occlusion of light path, and described light blocks
Thing is when the acceleration of the different directions of acceleration transducer changes, and light shelter changes it in bright finish
Different light paths is also blocked in position, and described photosensitive unit is used for transmitting acceleration information.
Such as Fig. 1 to Fig. 3, acceleration transducer includes longitudinal direction (Y and Y ' direction) light path four and horizontal stroke
To (X and X ' direction) light path four, four lateral light paths equidistantly and are parallel to each other, four longitudinal light
Road is parallel to each other.Lateral light paths four is respectively A and A ' to D and D ', longitudinal four difference of light path
It is in same level for E and E ' to H and H ', lateral light paths and longitudinal light path, i.e. bright finish.
Acceleration transducer horizontal and vertical all there is no acceleration time, light shelter is placed in position, bright finish middle.
This time shelter does not block arbitrary light path, and photosensitive unit can send signal light path being detected,
By this signal it is known that horizontal and vertical all there is no acceleration.And add when horizontal (such as X-direction) has
During speed, light shelter can move to X ' direction, then light shelter can block the light of GG ' or HH '
Road, then the photosensitive unit of GG ' or HH ' can export the signal being not detected by light, such that it is able to know
Acceleration transducer is in X-direction acceleration.Along with the increase of acceleration, light shelter also can be further from
Center, thus block farther light path, from the light path farther from bright finish center it is known that acceleration
Bigger.I.e. when horizontal and vertical all there is no acceleration time, light shelter is in bright finish center, along with not
The increase of equidirectional upper acceleration, light shelter also can toward acceleration opposite direction away from the distance at bright finish center
Increase, thus block the light path at edge, by the light path at detection edge it is known that the situation of acceleration.
In the present invention, the size of light shelter then can not have more than the spacing of two adjacent optical path
During acceleration, two light paths near bright finish center can be blocked, and when there being less acceleration, then only has
One can be blocked near bright finish central optical path, when acceleration is bigger, near the two of side, bright finish center
Individual light path can be blocked, by the circumstance of occlusion of detection light path it is known that the size of acceleration.
The concrete structure of acceleration transducer can be multiple, three embodiments given below.
Embodiment one
As it is shown in figure 1, light shelter is spherical, the side of described bright finish has the centre of sphere at bright finish opposite side
The first spherical structure, the concave surface of the i.e. first spherical structure points to bright finish or perhaps bright finish is in the first ball
In the concave surface of face structure, described smooth shelter is placed in described bright finish and is placed on the first spherical structure.The
The centre of sphere of one spherical structure is on the central axis of bright finish.So, as long as there being acceleration, spherical light hides
Block material will be away from central motion along the sphere of the first spherical structure, and acceleration is the biggest, and spherical light blocks
It is the most remote that thing moves, then can obtain acceleration value by detection photosensitive unit.
In certain embodiments, the opposite side of described bright finish has the centre of sphere the second sphere knot in bright finish side
Structure.I.e. first spherical structure has the second symmetrical therewith spherical structure, the second sphere knot relative to bright finish
Structure can avoid spherical smooth shelter to run out of, and acceleration transducer can be used reversely with front.
In the embodiment that the curvature of the first spherical structure is different from the curvature of the second spherical structure, the present invention adds
Velocity sensor, when front or back is placed, has different certainties of measurement.By adjusting the first sphere
The curvature of structure, thus it is possible to vary light shelter is in the deviation distance size of same acceleration, so that add
Velocity sensor can produce different acceleration ranges and precision.
Embodiment two
As in figure 2 it is shown, described smooth shelter is connected with bright finish surrounding by elastic component.Elastic component can be
Elastic force is uniform, and when light shelter is at bright finish center, now in all directions, acceleration should be zero.Specifically
Embodiment in four sides of acceleration transducer, can all connect a bullet in the center of every one side
The elastic component that power, length are equal, the other end of elastic component is connected with light shelter again.Elastic component can
To be rubber band or spring etc..By adjusting elastic force or the weight of light shelter of elastic component, permissible
Change the light shelter deviation distance size in same acceleration, so that acceleration transducer can produce
Raw different acceleration range and precision.
Embodiment three
As it is shown on figure 3, described smooth shelter is connected with the rope tying up to bright finish side, described smooth shelter
It is placed in described bright finish.In certain embodiments, rope is on the axis of bright finish, when zero acceleration,
Light shelter is in bright finish center under gravity, and when there being acceleration, light shelter can offset
Bright finish center.By adjust rope length, thus it is possible to vary light shelter same acceleration deviation away from
From size, so that acceleration transducer can produce different acceleration ranges and precision.
In certain embodiments, described luminescence unit is the light emitting diode of relative power saving.Described photosensitive list
Unit is the photoconductive resistance of low cost.
In certain embodiments, in order to avoid the interference of other light, luminescence unit has glow frequency, institute
State photosensitive unit and described glow frequency then output detections signal detected.The glow frequency i.e. only responded
Light, photosensitive unit just meeting output detections signal, otherwise, not output detections signal.This glow frequency can
Think 38KHZ.38KHZ is the glow frequency of IR remote controller, relatively common, cheap.
The foregoing is only embodiments of the invention, not thereby limit the scope of patent protection of the present invention,
Every equivalent structure utilizing description of the invention and accompanying drawing content to be made or equivalence flow process conversion, or directly
Or indirectly it is used in other relevant technical fields, the most in like manner it is included in the scope of patent protection of the present invention.
