Embodiment
The below lifts a preferred embodiment, and comes by reference to the accompanying drawings the clearer the present invention that intactly illustrates.
The electronic scales that the present invention has self-powered function comprises electrification structure and linkage structure.As depicted in figs. 1 and 2, electrification structure comprises first connecting rod 1, second connecting rod 2, universal driving shaft 3, main drive gear 4, the first duplicate gear 5, the second duplicate gear 6, generator 7 (generator 7 is microgenerator, and its rotor is the outer ring), unilateral bearing 8, back-moving spring 9, coupling shaft 10 and pin 19.As shown in Figure 3 and Figure 4, linkage structure comprises the scale pan 11, keeper 12, hoistable platform 13, base 14, connecting rod rack 15, balance bracket connecting rod 16, abutment sleeve 17 and register pin 18.First connecting rod 1 is connected by pin 19 with second connecting rod 2, and unilateral bearing 8 is put into the groove of second connecting rod 2, and universal driving shaft 3 passes unilateral bearing 8, and universal driving shaft 3 is fixed together by square hole and main drive gear 4.The pinion of main drive gear 4 and the first duplicate gear 5, the pinion of the gear wheel of the first duplicate gear 5 and the second duplicate gear 6, the gear engagement on the gear wheel of the second duplicate gear 6 and the generator 7.The central shaft of each gear is fixed on the gear mounting bracket (not shown), and the gear mounting bracket is fixed on the inside of base 14.Back-moving spring 9 is fixed on the two ends of coupling shaft 10.Coupling shaft 10 passes the upper hole of first connecting rod 1 and the preformed hole of hoistable platform 13, is fixed with jump ring, thereby makes both reach interlock.Keeper 12 is fixed together with hoistable platform 13, is positioned at the superiors of whole linkage structure, when needs generate electricity, the scale pan 11 can be placed directly on the keeper 12 at two ends.In twos cross connection of balance bracket connecting rod 16 is in the both sides of hoistable platform 13, and hoistable platform 13 is fixed on the base 14 by connecting rod rack 15.Abutment sleeve 17 is fixed on the preformed hole of hoistable platform 13 both sides with register pin 18.
During generating, the user puts into keeper 12 with the scale pan 11, press the scale pan 11, the scale pan 11 and hoistable platform 13 are moved downward, the coupling shaft 10 that links to each other with hoistable platform 13 drives first connecting rod 1 and second connecting rod 2 motions, at this moment second connecting rod 2 drives universal driving shaft 3 by unilateral bearing 8 and rotates (as shown by arrows, angle is as the criterion with material object).The main drive gear 4 that links to each other with universal driving shaft 3 by square hole drives the pinion rotation of the first duplicate gear 5, and the gear wheel of the first duplicate gear 5 drives the pinion rotation of the second duplicate gear 6.The gear that the gear wheel of the second duplicate gear 6 drives generator 7 rotates, thereby drives the rotor short time high-speed rotation of generator 7, thereby generates electricity.
In the upper end of first connecting rod 1 coupling shaft 10 being arranged, be provided with back-moving spring 9 at the two ends of coupling shaft 10, also can be Compress Spring or other elastic components.When the applied pressure effect finished, back-moving spring 9 will reset by coupling shaft 10 drive first connecting rods 1 and second connecting rod 2.Owing to adopted unilateral bearing 8, first connecting rod 1 and second connecting rod 2 can not drive main drive gear 4 backward rotation when resetting.
During movement, link up in order to make whole action, stressedly evenly in linkage structure, adopted balance bracket connecting rod 16 to intersect the structure of placing, like this can hoistable platform 13 in motion process, even be not center stressed, also can whole vertical motion.On two vertical direction, used array abutment sleeve 17 and register pin 18 (as shown in Figure 3), can make like this sliding friction be converted into rolling friction, reduced friction, thereby avoided locked.High-abrasive material is all used in the junction of all axles or pin, thereby increases the service life.In the process of user to this linkage structure acting, electrification structure produces alternating current simultaneously, is converted into direct current by rectifier, is sent to energy storing structure, and the supplied for electronic scale uses.
In sum, the present invention has long, low in energy consumption characteristics of low-carbon (LC), environmental protection and life-span.The present invention utilizes kinetic transformation to be the principle of electric energy, has self-powered function, so do not need external power supply, does not use dry cell, can not impact environment, very environmental protection.
Although more than described the specific embodiment of the present invention, it will be understood by those of skill in the art that these only illustrate, under the prerequisite that does not deviate from principle of the present invention and essence, can make various changes or modifications to these embodiments.Therefore, protection scope of the present invention is limited by appended claims.
