The beneficial effect who so sets up is: set up like this, set up two flexure strips on the rotor subassembly, flexure strip one end sets up on the support, the other end sets up in the connecting seat, rotate the in-process at the rotor subassembly, the flexure strip rotates thereupon, two flexure strips are owing to be the criss-cross form, the one end that the flexure strip inserted the connecting seat can be contradicted on cross slot inner wall, thereby make two flexure strips take place to twist reverse, thereby the energy storage, after reaching certain limit, can order about whole rotor subassembly gyration, reciprocating cycle, realize the control to the output shaft position, avoid the phenomenon of rotor subassembly off tracking to appear, simple structure simultaneously, do benefit to the realization, effectively improve overall structure's stability and result of use.

As a further setting of the utility model, the two elastic pieces are arranged at one end of the bracket far away from the output shaft.

The beneficial effect who so sets up is: the arrangement is more reasonable, the layout is simpler, and the production and the processing are more convenient.

As a further setting of the utility model, two flexure strips are first shell fragment and second shell fragment respectively, first shell fragment one end and support fixed connection, the other end are formed with the passageway groove, the inserting groove has been seted up on the second shell fragment, the second shell fragment corresponds inserting groove open-ended one end and support fixed connection, the inserting groove forms the cross of first shell fragment and second shell fragment with the cooperation of pegging graft of passageway groove.

The beneficial effect who so sets up is: set up like this, adopt this kind of form, it is more convenient to produce and process, and the equipment is maintained also very conveniently, has the clearance as preferring between first shell fragment and the second shell fragment, has certain floating space, can make full use of the elasticity of flexure strip, and better realization resets or the twisting motion effectively improves overall structure's result of use.

As the utility model discloses a further setting, be provided with the spacing groove on the shells inner wall, it is protruding to correspond the spacing groove position on the output shaft outer wall and be provided with the conflict, the protruding conflict of conflict forms spacing to output shaft pivoted on the spacing groove lateral wall.

The beneficial effect who so sets up is: through spacing groove and the bellied cooperation of contradicting, avoid the output shaft to excessively rotate, the width of spacing groove and output shaft pivoted scope looks adaptation here certainly can not interfere the rotation of output shaft, nevertheless when excessively deflecting, can play spacing effect, simple structure does benefit to the realization simultaneously, effectively improves overall structure's stability in use.

Detailed Description

The embodiment of the driving motor of the present invention is shown in fig. 1, fig. 2 and fig. 3: including casing 1, set up rotor subassembly and stator module in the casing 1, stator module sets up along rotor subassembly circumference, the rotor subassembly includes support and output shaft 2, the support cover is established outside output shaft 2, be formed with the holding chamber that is used for holding rotor core on the output shaft 2, output shaft 2 wears out the setting of casing 1, still be provided with two flexure strips 4 along 1 length direction of casing on the support, the setting of two 4 cross of flexure strip, it is provided with connecting seat 3 to correspond two 4 positions of flexure strip on the casing 1, be formed with in the connecting seat 3 and be used for supplying 4 male cross slots 31 of flexure strip, clearance fit between flexure strip 4 and the cross slot 31. The beneficial effect who so sets up is: set up like this, set up two flexure strips 4 on the rotor subassembly, 4 one ends of flexure strip set up on the support, the other end sets up in connecting seat 3, rotate the in-process at the rotor subassembly, flexure strip 4 rotates along with it, two flexure strips 4 are owing to be the criss-cross form, the one end that flexure strip 4 inserted connecting seat 3 can be contradicted on cross slot 31 inner wall, thereby make two flexure strips 4 take place to twist reverse, thereby the energy storage, after reaching certain limit, can order about whole rotor subassembly gyration, reciprocating cycle, realize the control to output shaft 2 positions, avoid the phenomenon of off tracking to appear in the rotor subassembly, and simple structure simultaneously, do benefit to the realization, effectively improve overall structure's stability and result of use.
