Embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer, the utility model is further specified below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only is used to explain the utility model, rather than be used to limit the utility model.
Flattening micro-generator unit structure and motion process figure that Fig. 8 is provided for the utility model embodiment for the ease of explanation, only show the relevant part of function therewith among the figure.
When initially not having the state of external force effect, under the attraction force acts of permanent magnet 3, the E of soft magnetic bodies 1, G end is close together with B, the D contact point of permanent magnet 3 respectively, and this moment, the E end of soft magnetic bodies 1 was the N magnetic pole, and the G end is the S magnetic pole.When under the momentary action of external force F, if strength greater than the resistance of magnet suction and spring, the E of soft magnetic bodies 1, G end then moves to A, the C contact point of permanent magnet 3, the magnetic polarity of soft magnetic bodies 1 was inverted to the E end and was the S utmost point this moment, the G end is the N utmost point.In this process, the moment magnetic polarity that conductive coil will be sensed soft magnetic bodies 1 two ends changes and produces electric energy and outwards export through P1 and P2 voltage both positive and negative polarity contact point.Subsequently; After the momentary action of external force F disappears; The elastic force effect of back-moving spring 4 makes E, the G end of soft magnetic bodies 1 break away from the attraction of permanent magnet 3, moves to initial position respectively and is close together with B, the D contact point of permanent magnet 3, and this moment, the magnetic polarity at soft magnetic bodies 1 two ends was reversed once more; The E end becomes the N magnetic pole, and the G end then is the S magnetic pole.Return in the process of initial position at this; The moment magnetic polarity that conductive coil will be sensed soft magnetic bodies 1 two ends once more changes and produces electric energy and by P1 and the output of P2 voltage both positive and negative polarity contact point, and different is this moment, voltage both positive and negative polarity and the voltage both positive and negative polarity that external force F does the time spent generation of P1 and P2 were opposite.
The key innovation of this embodiment is to adopt the electromagnetic induction electrification structure of flattening.This structure significantly reduces height and volume requirement, thereby has satisfied compact, the requirement of flattening self-powered of microsensor and/or control switch.Under external force F effect, the E of soft magnetic bodies 1, G two ends only need the very short distance of displacement, and soft magnetic bodies 1 two ends automatically returned to initial position after external force disappeared.In whole process, twice moment magnetic polarity counter-rotating will be realized in soft magnetic bodies 1 two ends, thereby make conductive coil can export double electric energy.
This embodiment can also have the following innovation that further expands:
A) soft magnetic bodies 1, conductive coil 2 and back-moving spring 4 position relative fixed, back-moving spring 4 links to each other with permanent magnet 3, and the center fixed of permanent magnet 3 is on fulcrum, and two ends then can move up and down.Initial position; The B, the D that remain permanent magnet 3 link to each other with E, the G end of soft magnetic bodies 1 respectively, and when external force F acted on an end of permanent magnet 3, its other end then moved round about; After external force F disappeared, the permanent magnet two ends automatically reset under the elastic force effect of back-moving spring 4.Whole process can make soft magnetic bodies 1 two ends produce the moment counter-rotating of twice magnetic polarity equally, thereby makes conductive coil can export double electric energy.
B) as shown in Figure 9, can load onto spring leaf 5 at an end of soft magnetic bodies, back-moving spring 4 links to each other with spring leaf 5.When external force F presses spring leaf 5, can drive soft magnetic bodies 1 two ends by spring leaf 5 equally and be subjected to displacement motion, produce the magnetic polarity counter-rotating thus, the magnetic polarity that conductive coil 2 is sensed soft magnetic bodies 1 two ends changes, and electromagnetic induction takes place and export electric energy.Spring leaf 5 has certain elasticity, the feel in the time of can improving external force F and press, and can improve the magnetic polarity switch speed at soft magnetic bodies 1 two ends, thus improve energy output, and help to reduce the contact wear between soft magnetic bodies 1 and the permanent magnet 3.
C) shown in figure 10; Can also respectively connect a back-moving spring 4a and 4b at the two ends of soft magnetic bodies 1; Make the two ends initial position of soft magnetic bodies 1 parallel with permanent magnet 3, external force F just can be from two different directive effects up and down like this, thereby have increased the use flexibility of this device.
The utility model is not limited to the execution mode that preceding text are discussed.More than the description of embodiment is intended in order to describe and explain the technical scheme that the utility model relates to.Conspicuous conversion or the alternative protection range that also should be considered to fall into the utility model based on the utility model enlightenment.Above embodiment is used for one of best implementation method that discloses the utility model, so that those of ordinary skill in the art can use numerous embodiments of the utility model and the purpose that multiple alternative reaches the utility model.
