Description

A kind of switch kinetic energy with door is the doorbell of the energy

Technical field

The utility model relates to a kind of doorbell, and especially a kind of switch kinetic energy with door is the doorbell of the energy.

Background technology

Present modal doorbell refers to electronic door bell more, and it generally uses two joint No.5 cells as the energy, and after triggering push button was outdoors pressed by the people, the doorbell circuit in the door will drive loudspeaker and send prompt tone or play the music of storage in advance.

But this electronic door bell power consumption is more, and a pair of No.5 cell generally only can use about half a year.And scrap dry battery can cause environmental pollution, and the production run of dry cell also can produce detrimental substance.

On the contrary, human living environment all can have the existence of door, the action of opening the door, closing the door and also just having become people almost must do every day.In the process of opening the door, closing the door, have the transfer of energy, if be not used, these energy will consume in vain.Therefore, make full use of the kinetic energy that opens the door and close the door, be translated into electric power and supply doorbell to use, see through and save the effect that the used electric power of doorbell can reach environmental protection.

The utility model content

The switch kinetic energy with door that the technical matters that the utility model will solve provides a kind of energy-saving and environmental protection is the doorbell of the energy.

For solving the problems of the technologies described above, the technical scheme that the utility model is taked is: a kind of switch kinetic energy with door is the doorbell of the energy, comprises doorbell circuit and is installed in the loudspeaker on the door; The input end of the output termination loudspeaker of said doorbell circuit; Its key is: also comprise TRT and energy-storage units; Said TRT comprises support, hinge, push rod, torsion spring, arc-shaped rack and Dyn.; One end of said support is fixed on the wall of rotating shaft one side of door; Its other end is fixed with the hinge of the rotating shaft that is parallel to door; Hinge is connected with the bottom of the push rod that can rotate around it, and the bottom of push rod also is with torsion spring, and the two ends of torsion spring are separately fixed on support and the push rod; The top of said push rod is fixed with the arc-shaped rack of a relative side that is positioned at door; The gear of installing in the rotating shaft of said arc-shaped rack and Dyn. is meshed; Said Dyn. is fixed on the wall above the door, and its output terminal connects the input end of doorbell circuit through energy-storage units.

Said energy-storage units comprises rectification circuit, super capacitor and mu balanced circuit; The output terminal of said Dyn. connects the input end of super capacitor through rectification circuit, and the output terminal of said super capacitor connects the input end of doorbell circuit through mu balanced circuit.

Said TRT also comprises the pulley that is installed in the push rod top.

Adopt the beneficial effect that technique scheme produced to be: the utility model with the kinetic energy of door in the open and close process as the energy; Utilize push rod and arc-shaped rack to drive the Dyn. generating; And energy storage device adopts the super capacitor of life-span length, reliable operation, has the advantage of energy-saving and environmental protection.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.

A kind of switch kinetic energy with door shown in Fig. 1-2 is the doorbell of the energy, comprises doorbell circuit and the loudspeaker that is installed on the door 8; The input end of the output termination loudspeaker of said doorbell circuit; Its key is: also comprise TRT and energy-storage units; Said TRT comprises support 1, hinge 2, push rod 3, torsion spring 4, arc-shaped rack 5 and Dyn. 6; One end of said support 1 is fixed on the wall 9 of door 8 rotating shaft one side; Its other end is fixed with the hinge 2 of the rotating shaft that is parallel to door 8; Hinge 2 is connected with the bottom of the push rod that can rotate around it 3, and the bottom of push rod 3 also is with torsion spring 4, and the two ends of torsion spring 4 are separately fixed on support 1 and the push rod 3; The top of said push rod 3 is fixed with the arc-shaped rack 5 of a relative side that is positioned at door 8; The gear of installing in the rotating shaft of said arc-shaped rack 5 and Dyn. 6 is meshed; Said Dyn. 6 is fixed on the wall above the door 8, and its output terminal connects the input end of doorbell circuit through energy-storage units.

Above-mentioned doorbell circuit and loudspeaker can be selected universal circuit or model for use.When door 8 was opened or closed, the arc-shaped rack 5 on push rod 3 tops all can drive Dyn. 6 and rotate, and makes its output DC ability.

Be illustrated in figure 3 as the schematic block circuit diagram of the utility model.Said energy-storage units comprises rectification circuit, super capacitor and mu balanced circuit; The output terminal of said Dyn. 6 connects the input end of super capacitor through rectification circuit, and the output terminal of said super capacitor connects the input end of doorbell circuit through mu balanced circuit.Rectification circuit is transformed into the unipolarity direct current with the bipolarity direct current of Dyn. 6 output, then super capacitor is charged, and the utility model can be chosen more than the 2.5V withstand voltage and appearance value at the super capacitor of 5-10F specification; Because the direct current of super capacitor output is not constant, therefore can not doorbell circuit be directly supplied with in its output, but handled via mu balanced circuit earlier, be stable voltage of doorbell circuit output.

The initial energy storage of super capacitor is zero, need could accomplish initial charge through the normal switch door about five times, and doorbell circuit gets final product work; Each switch door subsequently all can in case be charged to the fullest degree, charge into even without new electric energy super capacitor accumulation charging afterwards, and this doorbell is also sustainable to be pressed aloud more than 20 times.

Said TRT also comprises the pulley 7 that is installed in push rod 3 tops.When push rod 3 is promoted by door or under the effect of torsion spring 4, returns back to initial bit, can abut against on the door, pulley 7 can be prevented the scratch between the throw-out lever 3 and the shop front.
