For achieving the above object, the technical solution of the utility model is:
A kind of magnetic suspension drive mechanism, comprise lower casing (1), the upper casing (8) that matches with lower casing (1), bearing (2) between lower casing (1) and the upper casing (8), bouncing plate (7), shaker arm (3), run through bearing (2) successively, the axle core (6) of shaker arm (3) and bouncing plate (7), magnetic receiver (4), ferro-aluminum boron magnets (5), it is characterized in that: described axle core (6) one ends connect lower casing (1) by bearing (2), axle core (6) other end connects upper casing (8) by bouncing plate (7), shaker arm (3) is fixedly mounted on the core (6), and ferro-aluminum boron magnets (5) relies on magnetic receiver (4) to be fixed on the shaker arm (3);
Further, it is characterized in that: the inner ring of described axle core (6) one ends and bearing (2) is nested together, and is fixed in the lower casing (1); Axle core (6) other end passes the center of bouncing plate (7), welds together with bouncing plate (7), and is fixed on the upper casing (8), thereby make a core (6) left-right rotation on the fixedly center of circle of standard;
Further, it is characterized in that: described bouncing plate (7) is vertical with axle core (6), comprises outer enclosed construction and internal layer chip architecture of the spring, and its internal layer chip architecture of the spring is the skew symmetry structure.
The electromagnet that the utility model employing magnetic can be regulated variation drives shaker arm and does movement in a curve as electromagnetic induction device, makes core left-right rotation on the fixedly center of circle of standard, thereby has improved the transmission efficiency of magnetic suspension drive mechanism, has reduced the structure wearing and tearing; Be stopping means with the bouncing plate simultaneously, can make the motion amplitude of shaker arm remain on optimum range; In addition, it is rational in infrastructure, uses and installs simply, and stability is high, is applicable to electric cleaning series products such as electronic clean brush, electric toothbrush, electric shaver.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
In description of the present utility model, it will be appreciated that, term " on ", close the orientation of indications such as D score, " preceding ", " back ", " interior ", " outward " or position is based on orientation shown in the drawings or position relation, only be the utility model and simplification description for convenience of description, rather than indication or the hint device of indication or element must have specific orientation, with specific orientation structure and operation, therefore can not be interpreted as restriction of the present utility model.
In description of the present utility model, need to prove that unless clear and definite regulation and restriction are arranged in addition, term " installation ", " linking to each other ", " connection " should be done broad understanding, for example, can be fixedly connected, connect integratedly, also can be to removably connect; It can be the connection of two element internals; Can be directly to link to each other, also can link to each other indirectly by intermediary, for the ordinary skill in the art, can concrete condition understand the concrete implication of above-mentioned term in the utility model.
Please refer to shown in Figure 1, the utility model magnetic suspension drive mechanism, comprise lower casing (1), the upper casing (8) that matches with lower casing (1), bearing (2) between lower casing (1) and the upper casing (8), bouncing plate (7), shaker arm (3), run through bearing (2) successively, the axle core (6) of shaker arm (3) and bouncing plate (7), magnetic receiver (4), ferro-aluminum boron magnets (5), it is characterized in that: described axle core (6) one ends connect lower casing (1) by bearing (2), axle core (6) other end connects upper casing (8) by bouncing plate (7), shaker arm (3) is fixedly mounted on the core (6), and ferro-aluminum boron magnets (5) relies on magnetic receiver (4) to be fixed on the shaker arm (3).
