In the present embodiment, the second vehicle frame 200 includes main part 220 and mounting seat 230.Main part 220 and mounting seat 230
The structure that can be formed in one.Second wheel 210 is located on the main part 220 of the second vehicle frame 200 and rotatable.In this implementation
In example, the second wheel 210 has two, and two the second wheels 210 and first wheel 110 form tricycle structure.It can manage
Solution, in other embodiments, the quantity of the second wheel 210 is not limited to two, can also such as there was only one, or three or three
With first-class.
The total quantity of first wheel 110 and the second wheel 210 is preferably at least three, or and two, for sum
Measure as two, the first wheel 110 and 210 at least one of wheel of the second wheel are wide larger, steady in order to be formed when turning to
Fixed support.
Mounting seat 230 has two installation portions 232 being oppositely arranged.There is gap between two installation portions 232.It is preferred that
, two installation portions 232 tilt upward setting relative to main part 220, namely installation portion 232 and main part 220 (or it is horizontal
Face) between setting at an acute angle.It is furthermore preferred that the angle between installation portion 232 and main part 220 is 10 °~60 °.
Steering spindle 300 is fixed or is rotatably located on the second vehicle frame 200.Specifically, in the present embodiment, steering spindle 300
Two installation portions 232 of mounting seat 230 are arranged in, and are rotatably connected by bearing (not shown) respectively with two installation portions 232

Be rotatably connected between the vehicle frame 200 of frame 100 and second, operator need turn to when, can by tilt the first vehicle frame 100,
Make the first wheel 110 direct of travel and the second wheel 210 direct of travel it is inconsistent, and the deviation side of the second wheel 210
Cooperation can be turned to the direct of travel just with the first wheel 100, so as to which turning radius is small, operator can easily, easily
Realize and turn to.The above-mentioned vehicles 10 are with radius of turn is small, be easy to folding, safe, easily operated, simple in construction, cost is low
The advantages that.
Further, by setting steering spindle 300 from its bottom to sensing opposed vertical direction the second car of direction at the top of it
The afterbody of frame 200 deviates, and angle formed by the axial direction of steering spindle 300 and vertical direction is preferably acute angle, and operator tilts the
The direction of one vehicle frame 100 is consistent with the direction that the vehicles 10 rotate, and ensure that the gravity of body with turning to caused centrifuge
Dynamic balance, and the second wheel 210 will not be liftoff easily when turning to, so as to ensure that the security of operator；It is this in addition
Steering mode more meets the engineering mechanics and body intuition of people, can bring the more experience senses of operator and enjoyment of riding, have
Higher practical value.
It is understood that in other embodiments, be also not necessarily limited to whole first vehicle frame 100 relative to the second vehicle frame tiltable or
Rotatably, as long as the first vehicle frame 100 can close to one end of steering spindle 300 close to one end of steering spindle 300 and the second vehicle frame 200
Relatively rotate, and the first wheel 110 is different from the direct of travel of the second wheel 210, realizes that synchronous matching turns to, accordingly
Ground, when the first vehicle frame 100 close to one end of steering spindle 300 and the second vehicle frame 200 close to one end of steering spindle 300 in same direction
When, the straight line of the vehicles 10 is advanced.
In addition, it is appreciated that in other embodiments, the steering mode and traditional level that can also use the present embodiment turn
Motor-car handle drives the mode that the mode of the first wheel steering is combined.
Position is relatively fixed between " fixation " described herein refers to each part, including fixed using welding, threaded connection etc.
Mode is fixed, and the position of each part is relatively fixed under certain the one-level state being also included within multistage adjustable state.
Each technical characteristic of embodiment described above can be combined arbitrarily, to make description succinct, not to above-mentioned reality
Apply all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, the scope that this specification is recorded all is considered to be.
Embodiment described above only expresses several embodiments of the present utility model, and its description is more specific and detailed,
But therefore it can not be interpreted as the limitation to utility model patent scope.It should be pointed out that the common skill for this area
For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to
The scope of protection of the utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
