As shown in Figure 1, be the utility model structural representation.As seen from Figure 1, distinguishing feature of the present utility model is in front tube＜4〉and vehicle seat＜19 below vehicle frame＜3 between an extension spring＜13 are housed; And vehicle frame＜3 formed by two zigzag pipes. this structure with traditional three-wheel vehicle is just different widely.As can be known from Fig. 2, in front tube＜4〉the lower end weld last extension spring header board＜12, there is a hole its outer end, extension spring＜13〉an end make form of hooks, penetrate in this hole; Extension spring＜13〉the other end also make form of hooks, penetrate extension spring bolt＜14〉an end with holes, and extension spring bolt＜14〉the other end screw thread is arranged, it is penetrated plate＜15 after the extension spring〉an end with holes, then with adjusting female＜16〉with extension spring＜13〉and extension spring bolt＜14 be connected front tube＜4 and vehicle frame＜3 between, plate after the extension spring＜15〉be to be welded on vehicle seat＜19 vehicle frame＜3 of below on. in vehicle frame＜3〉the front portion of two zigzag pipes, promptly in front tube＜4〉the front, corresponding aperture is arranged, front limit pipe＜2〉with front limit bolt＜23〉pass this hole, use front limit nut＜26 again〉fixing, front limit pipe＜2〉an outside and front tube＜4 outside contact. rear position margining plate＜24〉be to be welded on vehicle frame＜3 two zigzag pipes on, its position is in front tube＜4〉the back, apart from front tube＜4〉be the 5-10 centimetre; At back limiting stopper＜22〉a side have one highly be slightly larger than rear position margining plate＜24 breach of thickness, this breach is stuck in rear position margining plate＜24〉on, back limiting stopper＜22〉with rear position margining plate＜24 on corresponding aperture is arranged, with back limited bolt＜21〉and back stop nut＜25 with after limiting stopper＜22 be fixed on rear position margining plate＜24 on.As can be known from Fig. 3, preceding ratchet＜8〉be screwed in front-wheel＜10 on, before ratchet holder＜7 be fastened on bent axle＜9 on, in preceding ratchet holder＜7〉the upper end with bearing pin with preceding ratchet＜6 be connected preceding ratchet holder＜7 on, before ratchet＜6 the top have one before reed＜28 push down preceding ratchet＜6, preceding reed＜28〉be with front pressuring plate＜27 be fixed tightly in preceding ratchet holder＜7 by screw on.As can be known from Fig. 4, back ratchet＜18〉be screwed in trailing wheel＜20 on, back ratchet＜29〉by back detent pin＜33〉be connected and rear axle＜17 with spring cotter close vehicle frame＜3 on, at back ratchet＜29〉the top back reed＜31 are housed push down back ratchet＜29, back reed＜31〉be with rear fender＜30 be fixed tightly in vehicle frame＜3 by screw on.

The utility model is finished it in use like this and is advanced:

1. the people is in vehicle seat＜19〉on, with pin by pedal＜11 drive bent axle＜9 thus ratchet＜6 before driving drive before ratchet whole car is travelled forward.

2. the people spurs handle＜1 〉, make front tube＜4〉by front limit pipe＜2〉limiting stopper＜22 backward〉when moving, front fork＜5〉make front-wheel＜10〉move forward, whole vehicle frame＜3〉move downward, and meanwhile, extension spring＜13〉be stretched, because back ratchet＜29〉be connected vehicle frame＜3〉on, it has stoped trailing wheel＜20〉motion backward, so when handle＜1〉when the swivel motion, even extension spring＜13〉when compressing, then by vehicle frame＜3〉and rear axle＜17 drive trailing wheel＜20 move forward; Because this moment, pin was just pedaled pedal＜11 〉, ratchet＜6 before the institute controlling before ratchet＜8, make front-wheel＜10〉can not move backward. and meanwhile, and whole vehicle frame＜3〉upward movement, till returning to reference position.This travelling forward allows the user feel to be similar to the sensation in wave advancing in the fluctuation up and down, and be joyful.

3. above-mentioned 1 and 2 action is combined, promptly one side goes to pedal pedal＜11 with pin 〉, one side spurs handle＜1 with hand again backward 〉, like this, whole car had both rotated and had advanced, and advanced doing up and down fluctuation again, thereby increase the speed that it advances, excited user's great interest again.

The utility model has changed the structure of existing three-wheel vehicle, the structure that adds forward and backward ratchet, ratchet with its unique extension spring reach not only rotate advance but also up and down fluctuation advance, not only increased the speed of advance of car, but also have the effect of exercising abdominal muscles, arm strength, grip and leg muscle, and greatly increased user's interest.This is that a kind of collection is ridden, body-building and amusement are the novel three-wheeled car of one.
