Abstract

The utility model relates to a micro-electricity energy-saving reciprocating device, comprising coils and a coil bobbin, wherein, a soft iron core is arranged in the coils, and the end surface of the iron core is provided with a permanent magnet. When the coils are applied with pulse current, generant magnetic field causes the iron core to generate polarity, which causes a reciprocating action of homopolarity repulsion and heteropolarity attraction for attracting and releasing to the permanent magnet without sustaining current. The utility model has the advantages of low coil temperature rise, no noise, energy saving, stable work, high accuracy rate and long service life, and be free from the influence of network voltage variation. The utility model can be used for low-voltage electrical equipment, such as a contactor, a circuit breaker, a relay, an electromagnetic valve, etc. The utility model can also be used for various locks, such as, a puzzle lock, an anti-theft lock and a remote control lock with a central control room.

Description

At present, the low-voltage electrical apparatus series products start enter operating state after, control circuit must be to the actuating coil continued power, consumed power not only, and produce AC noise and make coil heating; When net voltage changed, contact trembled, and formed electric arc easily, caused the contact adhesion and released and can not let go, and the action accuracy rate is low, not clear-cut, poor stability, and function is incomplete, and the useful life of product is low.

At present, various locks all are to use theory of mechanics, and key is inserted lock core, and the pellet shot from a slingshot that spring is headed on is parallel to plug face; Rotational lock core is stirred pintle hook lock, reaches the purpose of unlatching or blocks with pintle hook lock, is pinning.Its shortcoming is in any case, can only be single control, and it is poor to cause lock property, reliability, confidentiality, coding, is very easily opened by the robber, particularly can not manage control concentratedly.

A purpose of the present utility model is for overcoming the above-mentioned shortcoming of low-pressure electronic equipment product, replace former electromagnet part with the energy-conservation reciprocating apparatus of little electricity, reaching economize on electricity, noiseless, action accuracy rate height, strong interference immunity, highly sensitive, the adhesive rate of release is fast, the effect that mechanical endurance is long.

Another purpose of the present utility model is thoroughly to change present mechanical lock, the principle of permulation lock, produces novel locking device with the energy-conservation reciprocating apparatus of little electricity, and can make lock reach central authorities' control, and codified enters program control; Also the robber can be put into consciously, not need the Security Services to show up, only need the central control room button input signal, just the robber can be locked and enter house.

The purpose of this utility model realizes in the following manner:

This device comprises a coil, coil on coil rack, the iron core that has soft iron core or silicon copper sheet punching press to rivet in the coil rack; Wherein in the coil outside along being provided with permanent magnet on the end face of central shaft and iron core.

During work, coil is applied pulse current, the coil internal magnetic field makes iron core form the polarity of continuous variation, and with the operation principle that permanent magnet formation homopolar-repulsion and heteropole are inhaled mutually, promptly an end pushes away, and an end is inhaled, thereby reaches the reciprocating motion of adhesive and release.

The utility model compared with prior art has following advantage:

Owing to adopted permanent magnet, changed and commonly used the operation principle that low-voltage electrical apparatus generates an electromagnetic field with the coil power consumption, starting moment, change the polarity of soft iron core with a small pulse current, produce adhesive with permanent magnet and discharge, rely on the characteristic of permanent magnet to keep its operating state again, thereby reach energy-efficient, realized quick pick-up release, it is minimum to beat arc, atremia, and action is clear-cut, accurate, stable, and having multi-functionally, mechanical endurance is long.
