Embodiment
The present invention includes: the container of sealing; The guiding road that in described container, forms; The moving body that can in described guiding road, move; With the detecting sensor that detects moving body, described detecting sensor has: second test section of the heeling condition of first test section of the non-heeling condition of detection inclination sensor and detection inclination sensor, the position of the offset from vertical of the position that moving body stopped when described second test section was configured in and is in non-heeling condition with inclination sensor, thus, even vibrate in vertical direction at inclination sensor, or when being subjected to the impact of vertical direction, also do not judge the situation of inclination of being inverted with making a mistake.
Below, with reference to accompanying drawing, embodiments of the invention are described.Fig. 1 is the right section structural drawing (the F-F sectional view among Fig. 3) of having accommodated the inclination sensor of moving body (gas in cylinder, ball, liquid, the liquid etc.) in the guiding road, Fig. 2 is the further explanatory drawings of detecting sensor shown in Figure 1, and Fig. 3 is the sectional view of the X-X of Fig. 2.
In Fig. 1, the 1st, container.As shown in Figure 3, this container by: for example left and right sides wall 1a, the 1a that constitutes by glass material, be configured in the surrounding wall 1b that for example constitutes by glass material between left and right sides wall 1a, the 1a and be configured in wall 1a and surrounding wall 1b between intermediate materials (for example, the parts that are made of Si material etc.) 1c constitutes, and left and right sides wall 1a, surrounding wall 1b and intermediate member 1c engage with negative electrode.Also have, under the situation that left and right sides wall 1a, 1a, surrounding wall 1b are made of glass material, when engaging with negative electrode, can not be bonding between the glass, so need be by Si material (intermediate member).
These left and right sides wall 1a, surrounding wall 1b, intermediate materials 1c are made of appropriate materials such as resin, stupaliths, they can be engaged by using bonding material or suitable associated methods, or can also integral type form.In described container 1, be formed with subtriangular guiding road 2, in the guiding road, contain moving body 3.The top of guiding road 2 inherent surrounding wall 1b (top when being provided with the state of inclination sensor), be formed with protuberance 2a, make that moving body 3 can not rest on the central portion that guides the road when inclination sensor flips upside down, promptly, when flipping upside down, moving body must be in about the state of portion.And then, in the guiding road, be formed with recess shapes 2b in abutting connection with described protuberance 2a.
Be housed in the guiding road 2 moving body by right cylinder, ball, liquid pearl or charge in the gas in the liquid etc. one of them constitute (it is desirable for electric conductor), if inclination sensor tilts, then moving body 3 is mobile in guiding road 2.
In addition, on the wall around the guiding road 2, be formed with groove 4, described groove 4 prevents that moving body from connecting airtight attached to the wall that forms the guiding road.The section shape of this groove 4 just can adopt different shape so long as can prevent moving body 3 and wall 1a connects airtight the shape of adhering to.
Left and right sides wall 1a, 1a on guiding road 2 are formed with the detecting sensor 5 that detects moving body.Detecting sensor 5 by first test section (electrode) 5a that detects the state that inclination sensor do not tilt and second test section (electrode) 5b that detects the state that inclination sensor tilts constitute, first, second test section 5a, 5b are made of the pair of electrodes of subtend at least, and this electrode is arranged on the wall on guiding road with proper method.In addition, the electrode area of first test section, second test section forms area identical.
As shown in Figure 2, the first test section 5a extends the upper side be configured in the position that state moving body down that inclination sensor do not tilt is positioned at, and in addition, the second test section 5b correspondence is configured in the position, the left and right sides that moving body moves under the state of inclination sensor inclination.Described first, second test section 5a, 5b are when entering between each electrode at moving body, the fact of the electrostatic capacitance change between two electrodes can detect having or not of moving body thus.Also have, the first test section 5a can be cut apart with the X-X axle among Fig. 2, about can being configured to altogether four pairs.By about such formation four pairs, the vergence direction about can judging.
The testing agency that utilizes described test section is described.
Fig. 4 (a) (b) is based on output from electrode, detects the circuit diagram of the position of moving body.
Area in the pair of electrodes that will constitute the first test section 5a, the second test section 5b forms under the identical situation, shown in Fig. 4 (a), with judging the output signal of the electrostatic capacitance of the first test section 5a or resistance etc. and from the output signal of the electrostatic capacitance of the second test section 5b or resistance etc. in differential enlarging section, and judge heeling condition.
In addition, shown in Fig. 4 (b), judge from the output signal of the electrostatic capacitance of the first test section 5a or resistance etc. with from the output signal of the electrostatic capacitance of the second test section 5b or resistance etc. with microcomputer (the A/D port of microcomputer or I/O port), and judge heeling condition.The output state of this moment as shown in Figure 5.In Fig. 5, still judge the inversion heeling condition in the below by exporting the top that relative threshold is positioned at more than the certain value.In addition, Fig. 5 (b) judges the inversion heeling condition by the difference of obtaining output.
In the first test section 5a, the second test section 5b, paired electrode area is made as described above constant, the inversion heeling condition of the inclination sensor that can judge rightly.
Also have, detecting sensor is not limited to above-mentioned example, so long as can realize the sensor of same function, just can adopt the sensor of variety of way.
The effect of the inclination sensor that explanation is made of above structure.
At inclination sensor is under the non-heeling condition, and as shown in Figure 6, moving body 3 is positioned at the position of foot, detects this state by the first test section 5a.
If inclination sensor is inverted as illustrated in fig. 7 from this state, then moving body 3 adippings move, and detect this state by the second test section 5b.
Also having, when inclination sensor does not tilt, as shown in Figure 8, applying under the occasion of above-below direction ground vibratory impulse to inclination sensor, because moving body 3 moves up and down in the first test section 5a, is under non-heeling condition so can judge inclination sensor.
And because be formed with groove 4 on wall 1a, moving body or gas can not connect airtight attached on the wall, can steadily move, thereby can detect correct heeling condition.
More than, inclination sensor of the present invention is illustrated, but the guiding road is not limited to triangle, so long as can realize said function, just can use " V " word shape, circular-arc.In addition, moving body is not limited to cylinder, can also use toroidals such as disk, cylinder.Can also on guiding road, moving body etc., use the good material of slickness, reduce friction between the two, make moving body to move swimmingly.
In addition, in above-mentioned example, the example that guiding is provided with moving body in the road is illustrated, but can also be in the guiding road filling liquid and the moving body of layout circle column, spherical, gas therein.
In addition, stressed, but so long as can realize same function, just can adopt other testing agency the example of electrode as first, second test section.
And then the present invention can not break away from it in a word or under the prerequisite of principal character, implements other any ways.Therefore, the foregoing description only is the simple example of all aspects, does not play the qualification effect.
(industrial utilizability)
The present invention can utilize at cart and be inverted detecting sensor, acceleration transducer, inclination sensing Device etc.
