Working principle of the present utility model is:
During stored energy:
If output gear 20 is in the position of engaging with the second gear 6, then output gear 20 drives the second gear 6, the second largest fluted disc 61 of the second gear 6 drives the second wobble gear 9, under the effect of gear forces, the position of engaging with the first gear 5 (namely the axle of the second wobble gear 9 moves to the position near the first arcuate segment) put by second wobble gear 9, and then drive the first gear 5, first gear 5 volume spiral power spring storaging energy; Meanwhile, the first gear 5 drives the first wobble gear 8 to swing to upper end, thus the first wobble gear 8 is departed from and the engaging of the second gear 6.
If output gear 20 is in the position of engaging with the 3rd gear 7, then output gear 20 drives the 3rd gear 7,3rd gear 7 drives the second gear 6, the second largest fluted disc 61 of the second gear 6 drives the second wobble gear 9, under the effect of gear forces, the position of engaging with the first gear 5 (namely the axle of the second wobble gear 9 moves to the position near the first arcuate segment) put by second wobble gear 9, and then drives the first gear 5, first gear 5 volume spiral power spring storaging energy; Meanwhile, the first gear 5 drives the first wobble gear 8 to swing to upper end, thus the first wobble gear 8 is departed from and the engaging of the second gear 6.
When releasing energy: output shaft 10 is positioned at the left side (11A, 21A) in the first swing hole 11 and the second swing hole 21, and now the left side edge of slide plate 4 exceeds left side edge one segment distance of fixed block 3.Output gear 20 engages with the second gear 6.Gear-box releases energy, clockwork spring drives the first gear 5 to rotate, first gear 5 drives the 3rd small tooth plate of the first wobble gear 8, under the effect of gear forces, first wobble gear 8 swings to the position (namely the 3rd coupling shaft of the first wobble gear 8 moves to the position near the 3rd arcuate segment) of engaging with the second gear 6, the third-largest fluted disc 81 of the first wobble gear 8 drives the second small tooth plate of the second gear 6, the second largest fluted disc 61 of the second gear 6 drives output gear 20, and output gear 20 rotates counterclockwise driven gear case to left movement.When gear-box when having touched some thing in the process of left movement, owing to exceeding fixed plate 3 at left direction slide plate 4, slide plate 4 will be subject to active force to the right, thus drive output shaft 10 to move right, output shaft 10 moves to the right side (11B, 21B) in the first swing hole 11 and the second swing hole 21.Now output gear 20 engages with the 3rd gear 7, and does not engage with the second gear 6.Under the transmission of the 3rd gear 7, output gear 20 rotates clockwise, and driven gear case moves right.On right direction, the certain distance of fixed plate (namely the right side edge of slide plate 4 exceeds right side edge one segment distance of fixed plate 3) is exceeded again to the right after slide plate 4 slides.Gear-box is in movement process to the right, if touch some thing, slide plate 4 is just subject to active force left, so slide plate 4 slides left, output shaft 10 is driven to move to the left side (11A in the first swing hole 11 and the second swing hole 21,21A), got back to again initial state, gear-box is to left movement.Gear-box iterative motion like this.
In a word, the utility model adopts by arranging one group of fixed plate 3 and slide plate 4, and be fixed on slide plate 4 again after output shaft 10 is first swung hole 11 and the second swing hole 21 through first on gear-box, and output gear 20 turns to different gears (the second gear 6 and the 3rd gear 7) to engage from two, thus when gear-box touches some thing in the process of moving, slide plate 4 can drive output shaft 10 to move, and turning to of output shaft 10 itself also can be changed automatically.In a word, the utility model adopts simple mechanical structure, and the left and right achieving gear-box moving direction is freely changed.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also change above-mentioned mode of execution and revise.Therefore, the utility model is not limited to embodiment disclosed and described above, also should fall in the protection domain of claim of the present utility model modifications and changes more of the present utility model.In addition, although employ some specific terms in this specification, these terms just for convenience of description, do not form any restriction to the utility model.
