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 acceleration transducer of sphere formula, 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, 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.Light shelter is the spheroid that diameter is greater than adjacent optical path spacing, the side in described light face has first spherical structure of the centre of sphere at light face opposite side, namely the concave surface of the first spherical structure refers to that phototropic face or perhaps light face are in the concave surface of the first spherical structure, and described smooth shelter is placed in described light face and is placed on the first spherical structure.The centre of sphere of the first spherical structure is on the central axis in light face.Like this, as long as there is acceleration, spherical smooth shelter will along on the sphere of the first spherical structure away from central motion, acceleration is larger, spherical smooth shelter motion far away, then can obtain acceleration value by detection photosensitive unit.
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.
The utility model is not when having acceleration, two light paths near Guang Mian center can be blocked, when there being less acceleration, then only have one can be blocked near light face central optical path, when acceleration is larger, two light paths near side, Guang Mian center can be blocked, and can be known the size of acceleration by the circumstance of occlusion detecting light path.
In certain embodiments, the opposite side in described light face has second spherical structure of the centre of sphere in side, light face.Namely the first spherical structure has the second symmetrical with it spherical structure relative to light mask, and the second spherical structure can avoid spherical smooth shelter to run out of, and acceleration transducer can be used in front reversely.In the embodiment that the curvature of the first spherical structure is different from the curvature of the second spherical structure, acceleration transducer of the present utility model, when front or reverse side are placed, has different measuring accuracy.By adjusting the curvature of the first spherical structure, the deviation distance size of light shelter in same acceleration can be changed, thus make 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 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.
