Description
Technical field
The utility model relates to a kind of piezoelectric generating device, particularly relates to a kind of wireless switch on wall self-power supply device.
Background technology
Before the present utility model, present wireless switch on wall adopts Power supply more, but this mode exists defect, if traditional supply power mode is because its voltage is larger, has certain danger; Use Power supply, also keep away unavoidably and connect up on body of wall, waste resource, mounting arrangement is limited simultaneously, wastes time and energy.
Utility model content
The purpose of this utility model is just to overcome above-mentioned defect, develops a kind of wireless switch on wall self-power supply device.
The technical solution of the utility model is:
Wireless switch on wall self-power supply device, its technical characteristics is that rocker switch is arranged on many cantilever beam piezoelectric vibrators top; Described rocker switch is comprised of seesaw, back-up block, spring, and the V mouth end on back-up block coordinates with the groove rear portion in the middle of seesaw, other end linking springs; Described many cantilever beam piezoelectric vibrators comprise T-shaped mass, multi-disc piezoelectric bimorph, fixed block, there is respectively a fixed block on both sides, and centre is T-shaped mass, and one end of piezoelectric bimorph is arranged on fixed block, the other end is arranged on T-shaped mass, left and right symmetry; In rocker switch, the vertical range of the rotation of one end of seesaw is greater than rocker switch apart from the distance between many cantilever beam piezoelectric vibrators of below.
In described rocker switch, spring housing is connected on the curved end top of back-up block, and the other end withstands on seesaw.
In described many cantilever beam piezoelectric vibrators, it is left and right to being called multilayer that piezoelectric bimorph and T-shaped mass, fixed block form, and forms multilayer cantilever beam structure.
Porose in the middle of on back-up block in described rocker switch, to be connected on switch housing.
Fixed block in described many cantilever beam piezoelectric vibrators is connected on switch housing.
The beneficial effects of the utility model are to adopt piezo-electric generating principle, during break-make, the power acting on switch are converted to electric energy, are provided in signal emission module, and can realize integrated, simple in structure, easy to use.Compare existing wireless switchgear, do not need Power supply, without wiring, energy-conserving and environment-protective.
Accompanying drawing explanation
Fig. 1---the utility model structural principle schematic diagram.
Fig. 2---A-A cutaway view in Fig. 1.
In figure, each label represents that corresponding component names is as follows:
Seesaw 1, back-up block 2, spring 3, switch housing 4, T-shaped mass 5, piezoelectric bimorph 6, fixed block 7.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As shown in Figure 1, 2:
In the middle of back-up block 2, there is a hole for being fixed in switch housing 4, one end is curved end, the other end is V mouth end, V mouth end on back-up block 2 coordinates with seesaw 1 medial launder rear portion, the head of the curved end on back-up block 2 is connected with spring 3 with the front portion of seesaw 1 medial launder, and spring 3 is socketed in curved end top, and the other end withstands on seesaw 1, this is called rocker switch, seesaw, back-up block, spring, consists of; Many cantilever beam piezoelectric vibrators comprise T-shaped mass 5, multi-disc piezoelectric bimorph 6, fixed block 7, there is respectively a fixed block 7 on both sides, centre is T-shaped mass 5, and fixed block 7 is connected on switch housing 4, and one end of multi-disc piezoelectric bimorph 6 is arranged on the fixed block 7 on limit, the other end is arranged on the T-shaped mass 5 mediating, which floor left and right symmetry, has, in this example 4 layers, T-shaped mass 5 is looked almost in vacant state, thereby form multilayer cantilever beam structure; Rocker switch is installed on T-shaped mass 5 tops of many cantilever beam piezoelectric vibrators, both are parallel, and be all mounted in switch housing 4, but the vertical range of rocker switch and many cantilever beam piezoelectric vibrators is less than the vertical range that operation is rotated in any one end of the seesaw 1 in rocker switch.
The explanation of the utility model application process:
Above-mentioned parts are all installed in switch enclosure (omitting, not shown in FIG.), and switch enclosure is embedded on wall.When having turn on demand, press left end or the right-hand member of seesaw 1, the vertical range of operation is rotated in the one end that is less than the seesaw 1 in rocker switch due to the vertical range of rocker switch and many cantilever beam piezoelectric vibrators, therefore seesaw 1 will touch T-shaped mass 5 upper ends, the effect that T-shaped mass 5 is produced to power, and make T-shaped mass 5 produce displacement, thereby drive piezoelectric bimorph 6 flexural deformations on both sides, produce piezoelectric effect, on piezoelectric bimorph 6, produce electric charge, again owing to there being multi-layer piezoelectric twin lamella 6, the whole collections of electric charge that produce can be for the signal transmission circuit required electric energy that transmits, electrical equipment receiving terminal a long way off receives after signal, open electrical equipment, seesaw 1 is by under the effect at spring 3, and T-shaped mass 5 is because the elasticity of multilayer cantilever beam structure all returns to original state, again press seesaw 1 other end, can close electrical equipment.Like this, can realize switch place without wiring, without external power supply, realize switch self-powered.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although more used the terms such as rocker switch, cantilever beam piezoelectric vibrators herein, do not got rid of the possibility of using other term.Use these terms to be only used to describe more easily and explain essence of the present utility model; They are construed to any additional restriction is all contrary with the utility model spirit.
