Embodiment
See also Fig. 1 to shown in Figure 3, find out that by knowing among the figure drive unit of the present invention is provided with housing 1, be provided with coil winding 2, rotor 3, turn axle 4, rotating moving piece 5, deceleration fluted disc 6 in the housing 1, wherein:
This housing 1 is provided with upper shell 11 and lower house 12, upper shell 11 covers mutually with lower house 12, upper shell 11 inside surfaces are concaved with annular groove 111, convex with stopper section 112 in the annular groove 111, oblique first guiding incline 113 that is provided with of stopper section 112 1 side surfaces.
This coil winding 2 is positioned lower house 12, rotor 3 and turn axle 4 are articulated in coil winding 2 one sides, rotor 3 upper ends are provided with driving cog 31, and turn axle 4 one ends are articulated in the driving cog 31 of rotor 3, the other end passes upper shell 11, and turn axle 4 outer rims are arranged with and drive the rotating moving piece 5 that turn axle 4 rotates, and rotating moving piece 5 is near the bottom surface of upper shells 11, rotating moving piece 5 surfaces convex with the reference column 51 that is positioned at annular groove 111, and rotating moving piece 5 outer rims have passive tooth 52.
This deceleration fluted disc 6 is arranged at rotor 3 one sides, and deceleration fluted disc 6 has the first deceleration tooth 61 and the second deceleration tooth 62, and the first deceleration tooth 61 is engaged in the passive tooth 52 that driving cog 31, the second deceleration teeth 62 of rotor 3 are engaged in rotating moving piece 5.
See also Fig. 1 to shown in Figure 5, find out by knowing among the figure, the present invention is when using, pointer 7 is connected in the end that turn axle 4 passes upper shell 11, when coil winding 2 drives rotor 3 rotations, because driving cog 31 is engaged in the first deceleration tooth 61, the second deceleration tooth 62 is engaged in passive tooth 52, make deceleration fluted disc 6 drive rotating moving piece 5 turns, make rotating moving piece 5 drive turn axle 4 and pivot, allow pointer 7 be subjected to turn axle 4 to drive to pivot and indicate; When pointer 7 makes zero, see also Fig. 4 and shown in Figure 5, when driving rotating moving piece 5, rotor 3 pivots, and when the reference column 51 of rotating moving piece 5 touches the stopper section 112 that is convexly equipped with in the annular groove 111, because oblique first guiding incline 113 that is provided with of stopper section 112 1 side surfaces, and first guiding incline 113 becomes skewed with rotating moving piece 5 turn directions, therefore when reference column 51 touches first guiding incline 113 of stopper section 112, the acting force that reference column 51 is bestowed for stopper section 112, can be divided into the parallel component of parallel rotating moving piece 5 turn directions and the vertical stress component of vertical rotating moving piece 5 turn directions because of first guiding incline 113, wherein vertical stress component can be absorbed by stopper section 112, and parallel component just can produce reacting force to reference column 51, therefore reference column 51 suffered reacting forces can reduce relatively, so that rotating moving piece 5 can oppositely not pivoted or produce collision shake because of reacting force, to allow the state of making zero that indicates that pointer 7 can be correct.
See also shown in Figure 6 again, find out by knowing among the figure, oblique second guiding incline 511 that is provided with of these reference column 51 1 side surfaces, and second guiding incline 511 is parallel to first guiding incline 113, when second guiding incline 511 of reference column 51 touches first guiding incline 113 of stopper section 112, the acting force that reference column 51 is bestowed for stopper section 112, can be divided into the parallel component of parallel rotating moving piece 5 turn directions and the vertical stress component of vertical rotating moving piece 5 turn directions because of first guiding incline 113, wherein vertical stress component can be absorbed by stopper section 112, and parallel component can produce reacting force to reference column 51, and this reacting force can be divided into the parallel component of parallel rotating moving piece 5 turn directions and the vertical stress component of vertical rotating moving piece 5 turn directions via second guiding incline 511 again, and vertical stress component can be absorbed by reference column 51, and just can driving rotating moving piece 5, parallel component oppositely pivots, but because the effect of first guiding incline 113 and second guiding incline, 511 secondary component, making this drive the rotating moving piece 5 reverse parallel component that pivot greatly reduces, make rotating moving piece 5 can oppositely not pivot or produce collision shake more, make the state of making zero that indicates that pointer 7 can be correct because of reacting force.
Be with, the present invention is for solving the deficiency and the disappearance of known technology, its gordian technique is, the present invention utilizes the component effect of first guiding incline 113 and second guiding incline 511, the reacting forces that rotating moving piece 5 is oppositely pivoted greatly reduce can not shake rotating moving piece 5 because of reacting force oppositely pivots or produces to collide, and makes the state of making zero that indicates that pointer 7 can be correct.
Only the above, only be preferred embodiment of the present invention, when can not limiting scope of the invention process, so the displacement of the change of numerical value or equivalent elements such as with this, or, all should still belong to the category that patent of the present invention contains according to equalization variation and modification that the present patent application claim is done.
