Detailed description of the invention
In conjunction with accompanying drawing, this utility model is described in detail.
As it is shown in figure 1, this utility model electromotor includes upper shell 4, lower house 5, push rod 2, return spring 3, permanent magnet 6, coil 7, buffering colloid 8, piezoelectric patches 9, push rod supporter 10.Setting circular cylindrical cavity in upper shell 4, lower house 5, and cross section is all in inverted U, lower house 5 is fixed at upper shell 4 lower end, and the cross section of lower house 5 is more than the cross section of upper shell 4.Push rod 2 is in T shape, and push rod top 1 is positioned at above upper shell 4.The lower section length thereof of push rod 2 through upper shell 4, after, stretch in lower house 5.It is provided with permanent magnet 6 at the left and right inner surface of upper shell 4.Push rod 2 lower end is cased with coil 7, and coil 7 is positioned at upper shell 4.Push rod 2 upper end is cased with return spring 3, and return spring 3 two ends are inconsistent with push rod top, upper shell 4 upper end outer surface respectively.Push rod 2 and upper shell 4, the contact portion of lower house 5 are respectively equipped with push rod supporter 10, and two push rod supporters 10 are respectively arranged on below the inner surface of upper shell 4 upper end and above the outer surface of lower house 5 upper end (namely bottom of upper shell 4).It is provided with the piezoelectric patches 9 of area equation at the upper base surface of lower house 5, between piezoelectric patches 9 and lower house 5 top, is filled with buffering colloid 8.The bottom of push rod 2 sequentially passes through the top of upper shell 4, two push rod supporters 10 and the top of lower house 5, is fixedly linked with buffering colloid 8.
When External Force Acting is in push rod top 1, power is transmitted push rod 2 by push rod top 1 stress, and push rod 2 moves down, and return spring 3 is compressed.Now can be divided into two power generation processes simultaneously.
First process: push rod 2 moves down, driving upper shell 4 inner wrap coil 7 on push rod 2 to move down, owing to the permanent magnet 6 of upper shell 4 inner surface produces permanent magnetic field, coil 7 moves down inside upper shell 4, the magnetic induction line that cutting permanent magnetic field produces, thus produce electromotive force；When external force disappears, return spring 3 acts on, and makes push rod 2 move up, and drive is wrapped in coil 7 thereon and moves up, coil 7 cutting magnetic induction line again, produces electromotive force.
Second process: push rod 2 moves down, drives the internal buffering colloid 8 being fixed on push rod 2 of lower house 5 to compress, by pressure transmission to piezoelectric patches 9 after buffering colloid 8 pressurized, piezoelectric patches 9 compressive deformation, when external force disappears, return spring 3 acts on, and makes push rod 2 move up, buffering colloid 8 is driven to move up, it acts on the distress resolves on piezoelectric patches 9, and piezoelectric patches 9 recovers deformation, and piezoelectric patches 9 is at pressurized and recovers in deformation process, produce piezoelectric effect, produce electromotive force.
