The utility model is achieved in that
A kind of easy acceleration transducer, comprise light shelter, lateral light paths and longitudinal light path, lateral light paths and longitudinal light path square crossing form light face, lateral light paths and longitudinal light path all include the parallel and equidistant light path of two or more, adjacent optical path spacing in lateral light paths equals the adjacent optical path spacing in longitudinal light path, the diameter of light shelter is greater than the spacing of adjacent optical path, light path includes luminescence unit and corresponding photosensitive unit, photosensitive unit is for detecting the circumstance of occlusion of light path, described smooth shelter is when the acceleration of the different directions of acceleration transducer changes, light shelter changes its position in light face and blocks different light paths, described photosensitive unit is for transmitting acceleration information, described smooth shelter is connected with the rope tying up to side, light face, described smooth shelter is placed in described light face, rope is on the axis at Guang Mian center.
Further, described luminescence unit is light emitting diode.
Further, described photosensitive unit is photoresistance.
Further, described luminescence unit has glow frequency, and described photosensitive unit detects described glow frequency then output detections signal.
Further, described glow frequency is 38KHZ.
The utility model tool has the following advantages: the simple cost of structure is low, can customize the acceleration transducer of different accuracy easily.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model one embodiment.
Embodiment
By describing technology contents of the present utility model, structural attitude in detail, realized object and effect, accompanying drawing is coordinated to be explained in detail below in conjunction with embodiment.
Refer to Fig. 1, the utility model provides a kind of easy acceleration transducer, comprise light shelter 1, lateral light paths 2 and longitudinal light path 3, lateral light paths 2 and longitudinal light path 3 square crossing form light face, lateral light paths 2 all includes the parallel and equidistant light path of two or more with longitudinal light path 3, adjacent optical path spacing in lateral light paths equals the adjacent optical path spacing in longitudinal light path, the diameter of light shelter is greater than the spacing of adjacent optical path, light path includes luminescence unit and corresponding photosensitive unit, photosensitive unit is for detecting the circumstance of occlusion of light path, described smooth shelter is when the acceleration of the different directions of acceleration transducer changes, light shelter changes its position in light face and blocks different light paths, described photosensitive unit is for transmitting acceleration information.Described smooth shelter is connected with the rope tying up to side, light face, and described smooth shelter is placed in described light face.In certain embodiments, rope is on the axis in light face, and when zero acceleration, light shelter is in center, light face under gravity, and when there being acceleration, light shelter can center, offset light face.By adjusting the length of rope, the deviation distance size of light shelter in same acceleration can be changed, thus make acceleration transducer can produce different acceleration ranges and precision.
As Fig. 1, acceleration transducer includes longitudinal direction (Y and Y ' direction) light path four and horizontal (X and X ' direction) light path four, and four lateral light paths are equidistant and be 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 ', and longitudinal light path four is respectively E and E ' to 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 an acceleration time, 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, can know horizontal and vertically all do not have acceleration by this signal.And when laterally (as X-direction) has acceleration, light shelter can move to X ' direction, then light shelter can block the light path of GG ' or HH ', then the photosensitive unit of GG ' or HH ' can export signal light not detected, thus can know that acceleration transducer is in X-direction acceleration.Along with the increase of acceleration, light shelter also further from center, thus can block farther light path, can know that acceleration is larger from the light path farther from Guang Mian center.Namely when horizontal and vertical all there is no an acceleration time, light shelter is in Guang Mian center, along with the increase of acceleration on different directions, light shelter also can increase away from the distance at Guang Mian center in the other direction toward acceleration, thus block the light path at edge, the situation of acceleration can be known by the light path of Edge detected.
In certain embodiments, described luminescence unit is the light emitting diode of relative power saving.Described photosensitive unit is the photoresistance of low cost.
In certain embodiments, in order to avoid the interference of other light, luminescence unit has glow frequency, and described photosensitive unit detects described glow frequency then output detections signal.Namely only have the light of the glow frequency of response, photosensitive unit is meeting output detections signal, otherwise, not output detections signal.This glow frequency can be 38KHZ.38KHZ is the glow frequency of Infrared remote controller, relatively common, cheap.
The foregoing is only embodiment of the present utility model; not thereby scope of patent protection of the present utility model is limited; every utilize the utility model instructions and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
