Below in conjunction with accompanying drawing the utility model is done detailed explanation:
Fig. 1 is an explosive view of the present utility model;
Fig. 2 is the diagrammatic sketch of bowing behind the cover plate that removes of the utility model;
Fig. 3 is a kind of user mode figure of the present utility model;
Fig. 4 is another kind of user mode figure of the present utility model.
5, the specific embodiment:
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the utility model comprises the near front wheel (1), left socle (2), off-front wheel (3), right support (4), steering control level (5) and spring reset mechanism, wherein the near front wheel (1) and off-front wheel (3) are installed in respectively on left socle (2) and the right support (4), left socle (2) and right support (4) are installed on the chassis (12) by the rotating shaft above it (11) respectively, spring reset mechanism is connected with steering control level (5), steering control level (5) both sides are connected respectively on the protruding axle (13) of left socle (2) and right support (4), it also comprises magnet (8) and coil (9) and cover plate (10) in addition, cover plate (10) is installed in chassis (12) front top, between cover plate (10) and chassis (12), form an accommodation space (14), the boss (15) that protrude in the centre position of steering control level (5) places the middle part of accommodation space (14), coil (9) is installed in the inside, boss (15) bottom, both sides in coil (9), accommodation space (14) the inside is separately installed with magnet (8), and the terminals of coil (9) are connected on the control circuit board (16).Spring reset mechanism comprises back-moving spring (6) and backstay (7), the top of boss (15) is provided with alignment pin (17), back-moving spring (6) top is enclosed within on the alignment pin (17), the both sides of back-moving spring (6) are passed the dovetail groove (18) that steering control level (5) is provided with later respectively, and two tails of back-moving spring (6) place backstay (7) both sides.
Principle of the present utility model is as follows: when coil (9) is in circuit separately when connecting, because of there being electric current to produce magnetic field by causing self-induction of loop, directed moving under magnet (8) effect of coil (9) both sides, the orientation of coil (9) moves and can drive a retaining element, and--orientation of----steering control level (5) moves, the orientation of steering control level (5) moves and drives left socle (2) and right support (4) and do circle swing around axle center separately, thereby causes that left socle (2) and right support (4) make divertical motion;
When coil (9) is in circuit separately when disconnecting, because of no current passes through, self-induction magnetic field disappears,------spring (6) has the trend of the minimal deformation of returning to flexible member under the elastic force effect,------steering control level (5) is directed to be moved will to drive retaining element in spring (6) returns to the motion of minimal deformation, the orientation of steering control level (5) moves and will coil (9) be resetted in returning, left socle (2) and right support (4) are made circle swing around axle center separately, thereby cause that left socle (2) and right support (4) directed movement recover the origin-location.By the sense of current of change coil (9), can change self-induction of loop and produce magnetic direction, thereby the direction that the orientation of change steering control level (5) moves makes the utility model realize or right-hand rotation.
