Embodiment
The present invention is described in detail below in conjunction with drawings and Examples:
Consult Fig. 3 and Fig. 4, the preferred embodiment of inclination inducing system 10 of the present invention comprises the magnetic sensors group 4 of the position of a housing 1, a tumbler 2, a permanent magnet 5 and a detecting permanent magnet 5.
This housing have a diapire 13, by the upwardly extending surrounding wall of the periphery of this diapire 13 14, by the upwardly extending pivot 11 in the center of diapire 13, an and top cover 3 of removably being located on the surrounding wall 14, in the present embodiment, this surrounding wall 14 is to be the center around this diapire 13 and pivot 11 with pivot 11, and diapire 13, surrounding wall 14 and top cover 3 define an accommodation space 18 jointly, and this tumbler 2 promptly is to be placed in this accommodation space 18 with permanent magnet 5.What deserves to be mentioned is that the housing 1 in the present embodiment is for by 5 magnetic conductions of the permanent magnet in it, and have influence on the accuracy of the position of magnetic sensors group 4 detecting permanent magnets 5, the material of housing 1 is non-magnetic diamagnetism (dianagnetic) material.
What deserves to be mentioned is, because the electronic installation that inclination inducing system 10 goes into to use in installing is not when (figure shows), must be with specific orientation installing, so magnetic sensors group 4 could correctly be exported the electric signal of the position of representing permanent magnet 5, therefore, the surrounding wall 14 of present embodiment is formed with two big projections 15 that raise up in the side away from diapire 13, and two small convex pillars that raise up 16, big projection 15 lays respectively on a pair of relative corner of surrounding wall 14, small convex pillar 16 then lay respectively at surrounding wall 14 another on the relative corner, on the top cover 3 with respect to the position of big projection 15 with small convex pillar 16, then be formed with two large perforations 32 that can supply big projection 15 to be snapped into, and two little perforation 33 that can supply small convex pillar 16 to snap in; The snap-in structure of above-mentioned surrounding wall 14 and top cover 3, except can fixing for top cover 3, when also being available for users to install this inclination inducing system 10, by inspecting the position of large perforation on the top cover 3 32 with little perforation 33, just the mark feature on the present embodiment top cover 3 is judged the direction that inclination inducing system 10 should be installed.
In addition, in the present embodiment, one side of the diapire 13 contiguous top covers 3 of housing 1 also is formed with one first groove 121 and one second groove 122, this two groove 121,122 lays respectively at the opposite both sides of pivot 11, and respectively in order to ccontaining described magnetic sensors group 4, except this two groove 121,122, a side of these diapire 13 contiguous these top covers 3 also is formed with a collar flange that raises up 17, and this collar flange 17 is that center ring is around pivot 11 and described groove 121,122 with pivot 11.The quantity that the quantity that it should be noted that groove 121,122 will be looked the included magnetic sensors of magnetic sensors group 4 is provided with, and does not exceed with two shown in the present embodiment.
In the present embodiment, this tumbler 2 is generally to be a umbrella, having a transverse section is the handle shape and is hubbed at pivoting part 21 on the pivot 11 of housing 1, an and rotation section 23 that is connected in a side and the transverse section semicircular in shape of pivoting part 21, be formed with a storage tank 24 on the rotation section 23, this permanent magnet 5 promptly is to be installed in this storage tank 24, in the present embodiment, rotation section 23 can be subjected to the effect of gravity with this permanent magnet 5, and along with the inclination of housing 1 turns to the minimum position of surface level along this pivot 11.What deserves to be mentioned is, in order to reduce rotation section 23 when the turn, the friction that produces with diapire 13 and cause rotation sliding suitable, rotation section 23 is when rotating, its bottom surface 25 is to contact with collar flange 17 on the diapire 13, and can not allow whole bottom surface 25 and diapire 13 contact friction in large area.
In the present embodiment, this magnetic sensors group 4 comprises that one is embedded in first magnetic sensors 41 in first groove 121, and be embedded in second magnetic sensors 42 in second groove 122, first, second magnetic sensors 41,42 can be Hall magnetic force induction integrated circuit (Hall IC) or magnetic resistance inductor (Magneto-resistivesensor, be called for short MR sensor), and the situation that included inductor quantity of magnetic sensors group 4 and kind model thereof all must be looked practical application is set.It should be noted that in addition, in that being set, magnetic sensors to note its orientation at 41,42 o'clock, the permanent magnet 5 of make suring can match with the response characteristic of first, second magnetic sensors 41,42 when falling desired location, the response characteristic of various magnetic sensors such as Hall IC or MR sensor should be to be familiar with known to this technical field person, no longer adds to give unnecessary details at this.
Consult Fig. 5 and Fig. 6, set adopted in the present embodiment first, second magnetic sensors 41, the 42nd, HallIC, the N utmost point of permanent magnet 5 and the S utmost point then are the two ends of difference position in vertical direction, when the direction of inclination inducing system 10 past arrows 91 tilts, tumbler 2 and permanent magnet 5 just can drop on the position among Fig. 5, this moment, first magnetic sensors 41 and second magnetic sensors 42 all failed to sense permanent magnet 5, with first, second magnetic sensors 41,42 circuit that are electrically connected (figure does not show) just can utilize this state to do some corresponding application, for example: make straight the advancing of racing car in the electronic recreation.And when the direction of inclination inducing system 10 past arrows 92 tilts, tumbler 2 and permanent magnet 5 just can drop on the position among Fig. 6, just overlapping with second magnetic sensors 42, this moment, second magnetic sensors 42 just can be sensed permanent magnet 5, and to the corresponding signal of circuit (figure does not show) output that is electrically connected with it, this circuit just can utilize this signal to do other corresponding application, for example: make the racing car in the electronic recreation turn right.
Comprehensive the above, the known tilt sensor of similar size in Fig. 1, the structure that inclination inducing system 10 of the present invention combines tumbler 2 and permanent magnet 5, the influence that quality is brought when more increasing its rotation, just the gravity that is subjected to of permanent magnet 5 is bigger, also the direction that can be tilted along with housing 1 is exactly advanced toward the position that should go, and the vergence direction that inclination inducing system 10 is detected also just can more verily reflect the vergence direction of its applied electronic installation.
