In order to achieve the above purpose, the utility model adopts the technical scheme that: a flat plate voice coil motor, comprising: the stator is a conductor and comprises a base, a guide rail positioned on the base and an electric connector positioned at one end of the base; the rotor is a permanent magnet, and can move along the length direction of the stator after the stator is electrified.
In a preferred embodiment of the present invention, the base is a flat plate-shaped structure.
In a preferred embodiment of the present invention, the mover is a plate-shaped structure.
In a preferred embodiment of the present invention, the number of the guide rails is two and the guide rails are respectively located on two sides of the base.
In a preferred embodiment of the present invention, the rotor is connected to the guide rail through a plurality of sliding blocks.
In a preferred embodiment of the present invention, the fastening plates are disposed at both ends of the base.
The utility model discloses a preferred embodiment, be provided with the stopper on the mounting plate, the stopper with the active cell cooperation.
In a preferred embodiment of the present invention, the stator is a conductive metal material.
The utility model provides a defect that exists among the background art, the utility model discloses possess following beneficial effect:
the utility model discloses after the stator circular telegram, because the active cell is the permanent magnet, the stator is fixed mounting, so the active cell can follow stator length direction and move, the utility model discloses small can install in less space, compare in traditional linear electric motor and have higher precision to have high rigidity, do not have transmission clearance and flexibility, have advantages such as linear force journey characteristic and higher motor energy conversion rate.
Drawings
The present invention will be further explained with reference to the drawings and examples;
fig. 1 is a schematic overall structure diagram of the preferred embodiment of the present invention;
in the figure: 1. a stator; 11. a base; 12. a guide rail; 13. an electrical connection; 2. a mover; 3. a slider; 4. a fastening plate; 5. and a limiting block.
Detailed Description
The invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic drawings and illustrate, by way of illustration only, the basic structure of the invention, and which therefore show only the constituents relevant to the invention.
As shown in fig. 1, a flat type voice coil motor includes: the stator 1 is a conductive body, and the stator 1 comprises a base 11, a guide rail 12 positioned on the base 11, and an electric connector 13 positioned at one end of the base 11; active cell 2, active cell 2 is the permanent magnet, works as after stator 1 circular telegram, active cell 2 can be followed 1 length direction of stator moves the utility model discloses in, adopt the permanent magnet as active cell 2, after stator 1 circular telegram, because the permanent magnet has magnetic field, so can produce the electromagnetic force, because stator 1 is the stationary state, so under the electromagnetic force effect, 1 length direction of stator will be followed to power and moved, drives the load and moves, and active cell 2's stroke is let in the intensity decision of electric current in by stator 1, so the utility model discloses have better precision for traditional linear electric motor, and the utility model has the advantages of high rigidity, no transmission clearance and flexibility, have linear force stroke characteristic and higher motor energy conversion rate, can obtain more extensive use in the precision manufacturing field.
Specifically, the base 11 is a flat plate-like structure.
Specifically, the mover 2 is a flat plate-shaped structure.
Further, the number of the guide rails 12 is two and the guide rails are respectively located on two sides of the base 11, and the guide rails 12 can play a role in guiding the mover 2 in the moving process, so that the stability of the mover 2 in the moving process is ensured.
Specifically, the mover 2 is connected to the guide rail 12 through a plurality of sliders 3.
Further, the base 11 both ends all are provided with mounting plate 4, and the existence of mounting plate 4 can be consolidated base 11 both ends.
Specifically, be provided with stopper 5 on the mounting plate 4, stopper 5 with the active cell 2 cooperation, the existence of stopper 5 can be injectd the motion stroke of active cell 2.
Specifically, the stator 1 is a conductive metal material, in this embodiment, the stator 1 is an iron member, and the electrical connection member 13 is a copper member.
In summary, the utility model discloses after stator 1 circular telegram, because runner 2 is the permanent magnet, stator 1 is fixed mounting, so runner 2 can follow stator 1 length direction and move, the utility model discloses small can install in less space, compare in traditional linear electric motor and have higher precision to have high rigidity, do not have transmission clearance and flexibility, have advantages such as linear force stroke characteristic and higher motor energy conversion rate.
In light of the foregoing, it is to be understood that various changes and modifications may be made by those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
