Description
Technical field
The utility model relates to a kind of sensor for tilt angle, especially a kind of sensor for tilt angle that is used for electronic products such as mobile phone, handheld device, game paddle, MP3.
Background technology
Now, the various consumer goods of gravity sensing function have appearred having on the market, as mobile phone, mp3, game console etc.They can analyze its present located locus by gravity sensor, and the user can control them by changing its residing state (as tilting, rocking) in the space.But gravity sensor on the market, tilt sensor are very expensive.Not high at (electronic product of little cost) in some cases to the accuracy requirement of measurement of dip angle, just need this moment a kind of mode of cheapness to realize the inclination angle inducing function.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of sensor for tilt angle of little cost is provided.
According to the technical scheme that the utility model provides, a kind of sensor for tilt angle, feature is: comprise disk, in a side of disk infrared receiving device is set, opposite side is provided with the infraluminescence pipe; Be evenly distributed with grating by circumference on disk, the center of disk is provided with second rotating shaft, and being provided with in second rotating shaft can be around the pinion wheel of second rotating shaft rotation, pinion wheel and gear wheel engagement; The center of gear wheel is provided with first rotating shaft, and being provided with in first rotating shaft can be around the fork of first rotating shaft rotation, and an end of fork is provided with to hang and weighs; The output terminal of infrared receiving device is connected with the input end of single-chip microcomputer.
Described infrared receiving device is formed by two photodiodes or phototriode encapsulation.
The utility model measures by infrared receiving device that infrared ray is blocked and the number of times by grating changes into pulse and sends the single-chip microcomputer analysis to, and cost is low, and practical.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As Fig. 1～shown in Figure 2: sensor for tilt angle comprises gear wheel 1, pinion wheel 2, grating 3, fork 4, hang and weigh 5, first rotating shaft 6, second rotating shaft 7, disk 8, infrared receiving device 9, infraluminescence pipe 10 etc.
The utility model comprises disk 8, in a side of disk 8 infrared receiving device 9 is set, and opposite side is provided with infraluminescence pipe 10; Be evenly distributed with grating 3 by circumference on disk 8, the center of disk 8 is provided with second rotating shaft 7, and being provided with in second rotating shaft 7 can be around the pinion wheel 2 of second rotating shaft rotation, pinion wheel 2 and gear wheel 1 engagement; The center of gear wheel 1 is provided with first rotating shaft 6, and being provided with in first rotating shaft 6 can be around the fork 4 of first rotating shaft, 6 rotations, and an end of fork 4 is provided with to hang and weighs 5; The output terminal of infrared receiving device 9 is connected with the input end of single-chip microcomputer 11; Described infrared receiving device 9 is formed by two photodiodes or phototriode encapsulation.
In use, sensor for tilt angle described in the utility model is installed in mobile phone, handheld device, game paddle, electronic product inside such as MP3, the infrared ray that infraluminescence pipe 10 sends can pass grating 3 and be received by infrared receiving device 9, when device described in the utility model tilts with respect to first rotating shaft 6, because fork 4 and hanging weighs the 5 deviation of gravity center centers of circle that make gear wheel 1, make gear wheel 1 rotate, drive disk 8 and grating 3 rotations indirectly for pinion wheel 2 transmission of power by gear wheel 1 again, the infrared ray that infraluminescence pipe 10 sends is blocked by disk 8 discontinuously, infrared receiving device 9 outputs to single-chip microcomputer 11 with the form of pulse with the number of times of infrared ray by grating 3, by single-chip microcomputer 11 this pulse count signal is calculated corner again, be blocked and the sequencing of illumination can be judged disk 8 counterrotating directions according to two photoelectric receiving tubes in the infrared receiving device 9.
Feature of the present utility model is, hanging heavy 5 drive gear wheels 1 when the device run-off the straight relatively rotates, driving pinion wheel 2 by gear wheel 1 rotates, drive disk 8 and grating 3 rotations indirectly, the break-make number of times of infrared receiving device 9 when having increased disk 8 and turn over same angle, increased precision, measure that infrared rays are blocked and number of times by grating changes into pulse and sends single-chip microcomputer 11 to and analyze by infrared receiving device 9, judge the sense of rotation of disk 8 by the phase place difference of two photoelectric tube pulses in the infrared receiver 9, calculate inclination angles by single-chip microcomputer 11 more at last and be further processed or export.
