Embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed description.
Referring to Fig. 1 and Fig. 2, the utility model device is installed in portable small-sized electronic equipment internal, utilizes the people to walk or rocks namely and can carry out the self power generation charging to portable small-sized electronic equipment.
The utility model self-generating charger mainly comprises: balance staff 1, fork 2, arc-shaped permanent magnet 4, spring 5, stop 6, circuit board 8 and the more than one coil 7 that is complementary with arc-shaped permanent magnet 4.Circuit board 8 is used for the alternating current that coil 7 produces is carried out rectification, filtering, current limliting and voltage stabilizing.
The utility model self-generating charger can self with independent shell 11.For making designs simplification, also can save shell 11, and the shell 11 of the casing 12 of portable small-sized electronic equipment as self-generating charger.
As depicted in figs. 1 and 2, an end and the balance staff 1 of fork 2 are rotationally connected, and balance staff 1 is fixed on the shell 11 of self-generating charger or on the casing 12 of portable small-sized electronic equipment; The other end of fork 2 is the swinging end 3 of fork 2.Such as Fig. 1 and shown in Figure 5, arc-shaped permanent magnet 4 is fixed on the swinging end 3; Coil 7 is adjacent with arc-shaped permanent magnet 4, and coil 7 is fixedly mounted on the casing 12 of the shell 11 of self-generating charger or portable small-sized electronic equipment.When swinging end 3 swings back and forth take balance staff 1 as fulcrum, drive arc-shaped permanent magnet 4 and do oscillating traverse motion take balance staff 1 as fulcrum, form relative motion thereby make between arc-shaped permanent magnet 4 and the coil 7, and then make coil 7 inductions produce alternating current.
Coil 7 can be a coil or a plurality of coil, and a plurality of coils then consist of coil groups.Referring to Fig. 1 and Fig. 5, each coil 7 can be fixed on the shell 11 of the utility model self-generating charger or directly be fixed on the support 16 of casing 12 of portable small-sized electronic equipment.The size of arc-shaped permanent magnet 4, magnetic pole distribute and the intensity that magnetizes, the number of turn of coil groups, wire diameter and number, and the distance between arc-shaped permanent magnet 4 and each coil 7 etc., can determine according to the 13 required charge volumes of rechargeable battery in the portable small-sized electronic equipment.The ends A of coil 7, B link to each other with circuit board 8 by lead-out wire 9, and 10 circuit board 8 are linked to each other with the rechargeable battery 13 of portable small-sized electronic equipment by going between.
Referring to Fig. 6 and Fig. 7, the connected mode with each coil 7 in the coil groups of permanent magnet of the present utility model has two kinds of forms of series and parallel connections.The lead-out wire 9 of coil groups ends A, B links to each other with circuit board 8.
As shown in Figure 1, in the both sides of fork 2 spring 5 is installed respectively, an end of spring 5 is fixedly connected with fork 2, and the other end of spring 5 is fixedly connected with the casing 12 of the shell of self-generating charger 11 or portable small-sized electronic equipment.Like this, fork 2 can form a vibrational system jointly with spring 5, frequency basically identical (generally in the 0.2-5Hz scope) when the natural frequency of this vibrational system can be walked with the user with portable small-sized electronic equipment or rock, thus make this vibrational system and human body be in resonance state.Spring 5 can be column stretching or Compress Spring, leaf spring or wind spring.The installation site of spring 5 can be in the interlude position of fork 2, or in the position near swinging end 3 or balance staff 1.
As shown in Figure 3 and Figure 4, the structure of the magnetic pole of arc-shaped permanent magnet 4 is compartment, magnetizing direction be as shown in Figure 3 radially or as shown in Figure 4 axially.Arc-shaped permanent magnet 4 can carry out segmentation with a monoblock permanent magnet and magnetize, and also can form needed magnet by a plurality of little permanent magnet combinations.
In addition, in the both sides of fork 2 oscillating stroke that 6, two stops 6 of a stop are positioned at swinging end 3 is installed respectively also, is used for limiting the angle that swings back and forth of swinging end 3.Stop 6 is preferably made by having certain flexible material, can prevent like this when swinging end 3 vibration is excessive with the strong bump of stop 6 generations and produces strong vibration.
Because the natural frequency of the vibrational system that fork 2 and spring 5 form is walked with the people or the frequency when rocking is basically identical, when the portable small-sized power consumption equipment in being contained in pocket rocks in people's walking or to it, the 2 pairs of small excitations of fork that are in resonance state produce amplifies, make swinging end 3 produce very large displacement and speed, be installed between the arc-shaped permanent magnet 4 of swinging end 3 and the coil groups 7 and produce relative motion, make on the coil groups 7 and induce alternating current.The large I of the voltage and current of alternating current is adjusted by the number of turn and wire diameter, the Distribution of Magnetic Field of arc-shaped permanent magnet 4 and the distance between remanent magnetism and arc-shaped permanent magnet 4 and the coil 7 of control coil 7.Utilize 8 pairs of alternating currents of circuit board to carry out the processing such as rectification, filtering, current limliting, voltage stabilizing, thereby realize the charging to the rechargeable battery 13 of portable small-sized electronic equipment.
