Second vehicle frame 200 is used to saddle horse is stood or set for operator., can be for can be with the vehicles of saddle horse
Buttocks support component is set on two vehicle frames 200.The buttocks support component can be fixedly connected with the second vehicle frame 200, or
It is connected with the folding of the second vehicle frame 200.
In the present embodiment, the second vehicle frame 200 includes main part 220 and mounting seat 230.Main part 220 and mounting seat 230
Formation type structure can be made of 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
Connect.The rotational plane of bearing is parallel with installation portion 232, and the axial direction of steering spindle 300 and the rotational plane of installation portion 232 and bearing hang down
