Abstract

The utility model discloses a vibration diaphragm type resonance relay, characterized in that spring sets with difference mechanical vibration frequencies double as moving contacts are fixed on a vibrating diaphragm. The vibrating diaphragm can be a piezoelectric ceramic slice or a thin film. When an ac signal is additionally arranged on the piezoelectric ceramic slice, or a sound wave is transmitted to the thin film, the micro mechanical vibration of the piezoelectric ceramic slice or the thin film can lead one of reeds to harmonically vibrate. Moreover, the amplitude is slowly increased until the reed is contacted with a fixed contact. Thus, a switch is formed for controlling a corresponding executive circuit. The resonance relay does not need a coil, a magnetic steel or a pole shoe. The utility model has the advantages of light weight, simple structure and less power consumption. The vibration diaphragm type resonance relay is suitable for various remote control apparatus, such as aviation and voyage models and toys.

Description

Vibrating reed membrane type resonant relay

The utility model is about relay, particularly the invention of vibrating reed membrane type resonant relay.

In remote control equipment (touching type, toy) as wireless remotecontrol aviation, navigation, often use various relays, as switch, remove to control corresponding executive circuit.The electromagnetic resonant relay is a kind of public relay in remote control equipment.It mainly by by magnetic conductivity by different mechanical resonant frequencies and form as reed group, fixed contact and the coil of moving contact, pole shoe etc.Any AC signal is added on the coil, can both change reed group magnetic field on every side.When the changes of magnetic field frequency near or when equaling the mechanical resonant frequency of the wherein a slice reed in the reed group, this reed resonance, it is maximum that amplitude reaches, up to connecting with fixed contact by spells, as switch, remove to control corresponding executive circuit.Several reeds are arranged, and the frequency that changes AC signal just can be controlled the corresponding executive circuit in several roads.This electromagnetic resonant relay construction complexity, Heavy Weight, big, the debug difficulties of power consumption.

This novel purpose of usefulness is that a kind of resonant relay that does not need coil, pole shoe, magnet steel will be provided.

Its solution is: a slice vibrating reed film is arranged on base, and the reed group (one or more groups) with different mechanical resonant frequencies as moving contact is being fixed on vibrating reed film surface.When the vibrating reed film carries out slight mechanical oscillation, if its vibration frequency near or when equaling the mechanical resonant frequency of the wherein a slice reed in the reed group, this reed resonance, it is maximum that amplitude reaches, up to connecting with corresponding fixed contact, as switch, remove to control corresponding executive circuit.

In order to make the vibration of vibrating reed film, the material of vibrating reed film can be used piezoelectric ceramic piece, and the utility model promptly becomes the piezoelectric ceramic type resonant relay.Because piezoelectric effect when any AC signal is added on the piezoelectric ceramic piece, can both make piezoelectric ceramic piece vibrate slightly.If the vibrating reed film is made into diaphragm, the utility model then becomes the sound wave type resonant relay.When sound wave passes on the diaphragm, can cause the slight mechanical oscillation of diaphragm.

Further improvement of the utility model is that the two sides of vibrating reed film all has reed and base that corresponding fixed contact is arranged; Vibrating reed film and reed group can directly combine becomes a single piece.

The utility model is compared with prior art, has saved coil, pole shoe, magnet steel, has simplified structure, alleviate weight, reduced power consumption, this requires the lighter remote control equipment that is moving of weight for using powered battery, is particular importance.It can also be directly installed on the printed circuit board (PCB).
