In conjunction with attached drawing, the utility model is described in further detail.This specific embodiment is only to the utility model
Explanation, be not limitations of the present invention, those skilled in the art, can be according to need after reading this specification
The modification of not creative contribution is made to the present embodiment, but as long as in the scope of the claims of the utility model all by
The protection of Patent Law.
Embodiment 1: as depicted in figs. 1 and 2, a kind of more wheel bicycles of front-treadle type, including vehicle frame 1, it is installed on 1 front end of vehicle frame
Front fork 2, the front-wheel 6 for being installed on 2 lower end of front fork, the handlebar 3 for being installed on 2 upper end of front fork, the vehicle seat 4 being arranged on vehicle frame 1, with
And the foot pedal 5 on vehicle frame 1 is mounted on by central axis, 1 rear end of vehicle frame is equipped with transmission case 8, sets on the transmission case 8
There are several pairs of rear-wheels 7, the axis drives the rear-wheel 7 to rotate by chain conveyer.Chain conveyer is passed using conventional sprocket wheel chain
Sprocket wheel, winding chain between two sprocket wheels is arranged in axis and rear-wheel shaft in flowing mode, foot pedal 5 drives central axis, in
Axis drives rear wheel by chain conveyer.
Axis is arranged in the lower section of the vehicle seat 4, and the axis is located at the front of the handlebar 3, the axis, described
Handlebar 3 and the vehicle seat 4 it is in the horizontal direction projection be sequentially distributed from the front to the back, the axis to the front and back of the vehicle seat 4 away from
From be greater than the axis to the vehicle seat 4 up and down with a distance from.Vehicle seat 4 is movably arranged on the vehicle frame 1, can the relatively described vehicle frame
1 is moved forward and backward.Mounting plate 406 is fixedly installed on vehicle frame 1, the mounting plate 406 is equipped with elongated slot, the sliding of vehicle seat 4 peace
On the mounting plate 406, the lower section of the vehicle seat 4 is equipped with the guide post being plugged in the elongated slot, is spirally connected on the guide post
There is locking nut.The line at the center of axis and vehicle seat 4, minimum 20 ° of angle formed with horizontal plane, is up to 30 °.
As shown in Fig. 2, vehicle seat 4 includes seat plate 401 and backup plate 402, the backup plate 402 is articulated on the seat plate 401 simultaneously
The hinged place of relatively described 401 swing of seat plate, the seat plate 401 and the backup plate 402, which is equipped with, makes the backup plate 402 forward
The torsional spring 403 rotated afterwards.The rear end of seat plate 401 is equipped with mounting groove, the lower end of the backup plate protrude into the mounting groove and with institute
State seat plate 401 hingedly, the rear cell wall of the mounting groove is equipped with the arc convex 405 for being used to support the backup plate toppled over backward.Arc
Shape protrusion 405 at least two, above and below, the setting of front and back, two formation of arc convex 405 are used to support the backup plate
402 supporting oblique surface.Backup plate 402, which is equipped with, swings backward amplitude for protruding into the mounting groove, to adjust the backup plate 402
Adjustment block 404, the adjustment block 404 slip the backup plate 402 the back side and the relatively described backup plate 402 move up and down.It adjusts
The cross section of monolith 404 is right angled triangle, and the straight flange and bevel edge of the adjustment block 404 are caught between backup plate 402 and seat plate 401
Gap in, the bevel edge linear distribution of adjustment block 404 has multiple fixing grooves for being recessed inwardly, matching with arc convex 405.
Embodiment 2: as shown in figure 3, difference from Example 1 is, mounting plate 406 is rotatably installed in by articulated shaft
On vehicle frame 1,406 relative frame 1 of mounting plate is swung in left and right directions, vehicle seat 4 and 406 mounting means of mounting plate and 1 phase of embodiment
Together.When both legs are when forward to pedal, mounting plate 406 swings accordingly with having an effect for leg, reduces seat plate 401 to leg
Pressure.The lower end of backup plate 402 is equipped with the adjustable plate 407 for extending to 406 lower section of mounting plate, and articulated shaft is arranged in adjustable plate 407
The left and right sides is equipped with gap between adjustable plate 407 and mounting plate 406, equipped with spring 408 in gap, when 402 swing of backup plate
Adjustable plate 407 is adjusted at a distance from mounting plate 406, i.e. elastic force of the spring 408 to mounting plate 406, the back rake angle of backup plate 402
Degree is bigger, and adjustable plate 407 is smaller at a distance from mounting plate 406, and spring 408 is bigger to the elastic force of mounting plate 406, mounting plate 406
Amplitude of fluctuation in left and right directions is smaller.Because the hypsokinesis angle of backup plate 402 is bigger, when 406 amplitude of fluctuation of mounting plate is larger, vehicle
4 easier shakings of seat, and bicyclist almost rides in lying position at this time, balanced capacity control is relatively poor, is easy from vehicle body
Rolling is got off.
