Abstract
The utility model relates to a bistable state electromagnet actuator, which comprises an electromagnet, a positioning slide channel which is positioned beside the electromagnet and above the direction of the magnetic-field shaft line of the electromagnet, a steel actuating slide block which can be arranged on the positioning slide channel and can move along the direction of the magnetic-field shaft line, a compression spiral spring arranged between the steel actuating slide block and one end of the positioning slide channel, which approaches to the electromagnet, and a permanent magnet block arranged on one end of the positioning slide channel, which approaches to the electromagnet. When the utility model attracts the steel actuating slide block approaching to one side of the electromagnet, the steel actuating slide block can be attracted through the temporary electric conduction of the electromagnet; because the stable state is kept through the attraction of the magnetic force of the permanent magnet, the long-term electric conduction of the electromagnet can not be required; thereby, the electricity can be saved.
Description
The utility model relates to the structure of a kind of electromagnetic actuator, particularly a kind of electromagnetic actuator.
Electromagnetic Drive such as electromagnetically operated valve, electromagnetic switch product all has electromagnetic actuator, electromagnetic actuator has electromagnet, by the electromagnet, the magnetic field axis direction of electromagnet has and can carry out slide block along the steel that the magnetic field axis direction moves, steel is carried out between close electromagnet one end of slide block and locator slide compression helical spring.In use, when the electromagnet energising produces magnetic force, steel is carried out slide block and is drawn onto near electromagnet one side, this moment, helical spring was compressed, when the electromagnet outage, magnetic force disappears, and steel is carried out the elastic force of slide block because of compression helical spring, be bound to away from electromagnet one side, steel is carried out close electromagnet one side of slide block and be can be used for the opening and closing of drive fluid valve or electric switch away from the electromagnet two states.When this electromagnetic actuator was carried out slide block by the state of close electromagnet one side of electromagnet attraction at steel, electromagnet needed energising always, so relatively take.
The purpose of this utility model is in order to overcome above-mentioned deficiency, proposes a kind ofly when attracting steel to carry out slide block near the state of electromagnet one side, and electromagnet does not need the bistable electromagnetic actuator of always switching on.
The utility model is realized with the following method.
There is electromagnet in bistable electromagnetic actuator, by the electromagnet, have on the magnetic field axis direction of electromagnet and can carry out slide block along the steel that the magnetic field axis direction moves, steel is carried out between slide block and the electromagnet compression helical spring, permanent magnetic iron block is arranged on electromagnet, the magnetic field axis of permanent magnetic iron block and the magnetic field axis of electromagnet coincide, when having forward current to pass through in the electromagnet, the magnetic direction in the magnetic field that electromagnet produces is equal to or greater than the magnetic field intensity of permanent magnetic iron block with the magnetic direction magnetic field intensity identical, electromagnet in permanent magnetic iron block magnetic field.
During use, feed forward current to electromagnet of short durationly, the magnetic force of electromagnet and permanent magnetic iron block is in same direction, can carry out slide block to steel is attracted near electromagnet one side, because permanent magnetic iron block is arranged on electromagnet, after the forward current of short duration in the electromagnet disconnected, the elastic force that the magnetic force of permanent magnetic iron block can overcome spring was drawn onto steel execution slide block near electromagnet one side, although electromagnet is energising not, also can make steel carry out slide block and stably be in a kind of executing state.When more of short durationly when electromagnet feeds reverse current, the magnetic direction that electromagnet generates an electromagnetic field is opposite with the magnetic direction in permanent magnetic iron block magnetic field, the attraction that permanent magnet is carried out slide block to steel is offset, make steel execution slide block because of the elastic force of spring moves to away from electromagnet one side, make steel carry out slide block and stably be in another kind of executing state.
The utility model is when attracting steel to carry out the state of close electromagnet one side of slide block, be to use after the suction of steel execution slide block is come in electromagnet energising of short duration, keep stable state with the magnetic attraction of permanent magnetic iron block, electromagnet do not need to switch on always, so relatively power saving.
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is the schematic diagram of bistable electromagnetic actuator;
Fig. 2 is the schematic diagram of another kind of bistable electromagnetic actuator.
Among Fig. 1, there is electromagnet 1 in bistable electromagnetic actuator, the iron core of electromagnet 1 is a tubular iron core 2, have in the tubular iron core 2 and can carry out slide block 3 along the cylindrical steel that the magnetic field axis direction moves, between at the bottom of the pipe of cylindrical steel execution slide block and tubular iron core 2, compression helical spring 4 is arranged, iron core one end at electromagnet has permanent magnetic iron block 5, the magnetic field axis of permanent magnetic iron block 5 and the magnetic field axis of electromagnet 1 coincide, when when electromagnet 1 feeds forward current, the magnetic direction in the magnetic field that electromagnet 1 produces is identical with the magnetic direction in permanent magnetic iron block 5 magnetic fields, the magnetic field intensity of electromagnet 1 is equal to or greater than the magnetic field intensity with permanent magnetic iron block 5.
Among Fig. 2, there is electromagnet 6 in bistable electromagnetic actuator, the next door of electromagnet 6 has and can carry out slide block 7 along the steel that the magnetic field axis direction moves, steel is carried out on the at one end fixing lever 8 of slide block 7, compression helical spring 9 is arranged between lever 8 and the electromagnet, iron core one end at electromagnet has permanent magnetic iron block 10, the magnetic field axis of permanent magnetic iron block 10 and the magnetic field axis of electromagnet 6 coincide, when when electromagnet 6 feeds forward current, the magnetic direction in the magnetic field that electromagnet 6 produces is identical with the magnetic direction in permanent magnetic iron block 10 magnetic fields, the magnetic field intensity of electromagnet 6 is more than or equal to the magnetic field intensity of permanent magnetic iron block 10.
