Description

Sit happy driving

Technical field:

The present invention relates to the recreational vehicle of a kind of children, particularly one is seated and rides, and bipod tramples the happy driving of the seat that this car is moved ahead up and down in turn.

Background technology:

The recreational vehicle that the bipod that is seated in the market is trampled up and down is more rare, and the recreational vehicle bipod that is seated trampled up and down without hand is rare to see especially, the seat of the design people's earlier application makes merry car (patent No.: ZL2009202089048) although be provided with above-mentioned functions, and its speed is not ideal enough.

Summary of the invention:

Be departure point in line with designing the happy driving of seat that a kind of children's of being more suitable for amusement plays, allow children be sitting on this car, bipod tramples this car up and down in turn, and this car can be made to move ahead faster, the happy driving of the seat playing more refreshing.The object of the present invention is achieved like this: sit happy driving and comprise a vehicle body stand, a rocker, a tread mechanism, four cardan wheels and a vehicle seat, it is characterized in that: vehicle body stand comprises two standpipes of the right and left, a middle pipe and a screw pipe, two standpipes and seat Guan Sanguan example is welded into a chevron pointing, lambdoid two bottoms connect two cardan wheels, on the seat pipe on chevron pointing top, welding one screw pipe, a vehicle seat also installed by seat pipe; Rocker is an inversion T-shaped bar, a pipe is welded on the top of being inverted T-shaped bar, pipe is rotatably socketed on screw pipe, and pin with stifle, two bottoms of being inverted T-bar connect two cardan wheels, a tread mechanism is welded in the front portion of being inverted T-bar, and tread mechanism is made up of a step cross bar and two steps, and two step on the two being installed on step cross bar.

Effective effect of the present invention is: two standpipes and the seat Guan Sanguan also example welding that have employed vehicle body stand, make the outward appearance on these car both sides level and smooth, attractive in appearance, have employed and weld a screw pipe on the seat pipe on vehicle body stand top, and the pipe on rocker top is rotatably connected with it, the amplitude of fluctuation of rocker is strengthened, and the stroke of two cardan wheels be connected with rocker strengthens, thus improve speed, tread mechanism is directly welded on the front portion of rocker, and make the structure of this car more simple, cost is lower.

Accompanying drawing illustrates:

Fig. 1 is structural representation of the present invention

Fig. 2 is diagram before structure of the present invention

Fig. 3 is that left foot of the present invention tramples the schematic diagram that moves ahead

Fig. 4 is that right crus of diaphragm of the present invention tramples the schematic diagram that moves ahead

In figure: 1---vehicle body stand, 2---rocker, 3---tread mechanism, 4---cardan wheel, 5---vehicle seat; Wherein vehicle body stand 1 also comprises: 11---standpipe, and 12---seat pipe, 13---screw pipe; Rocker 2 also comprises: 21---be inverted T-bar, 22---and pipe; Tread mechanism 3 also comprises: 31---step cross bar, and 32---step.

Detailed description of the invention:

The happy driving of seat according to Fig. 1, Fig. 2 comprises vehicle body stand 1, rocker 2, tread mechanism 3, cardan wheel 4 and vehicle seat 5;

Described vehicle body stand 1 also comprises left and right standpipe 11, seat pipe 12 and screw pipe 13, described left and right standpipe 11 and seat pipe 12 3 are managed and example is welded into chevron pointing, the cardan wheel 4 described in two is connected bottom left and right standpipe 11 described in the chevron pointing of described vehicle body stand 1, on seat pipe 12 described in described vehicle body stand 1 chevron pointing top, welding screw pipe 13, described screw pipe 13 is threaded pipes in pipe, described seat pipe 12 is also installed a vehicle seat 5.

Described rocker 2, comprise and be inverted T-shaped bar 21 and pipe 22, described inversion T-shaped bar 21 be two arc-shaped bend pipe on weld a straight tube and form, welded top one pipe 22 of described inversion T-shaped bar 21, described pipe 22 is rotatably socketed on described screw pipe 13, and pin with stifle, two bottoms of described inversion T-bar 21 connect the cardan wheel 4 described in two.

Described tread mechanism 3 comprises step cross bar 31 and two steps 32, described step cross bar 31 is flat tubes, described step cross bar 31 is welded on the front portion of described inversion T-shaped bar 21, two described steps 32 are plastics steps, and two described steps 32 two of bolt and described step cross bar 31 is fixed.

Described cardan wheel 4 refers to: what be connected to described vehicle body stand 1 is welded into cardan wheel 4 described in two bottom lambdoid described two standpipes 11, with be connected to described rocker 2 described inversion T-shaped bar 21 liang of bottoms two described in cardan wheel, described cardan wheel 4 wheel band bearing, rotatably; The neck of wheel fork is also with bearing, rotatably.

When will this car move ahead time, pin 32 is trampled with left foot, the described cardan wheel 4 of described rocker 2 this car related produces forward thrust (see Fig. 3) to the left, pin 32 is trampled with right crus of diaphragm, the described cardan wheel 4 of described this car of rocker 2 inconjunction with produces forward thrust (see Fig. 4) to the right, repetition like this, can make the happy driving of seat move ahead with speed faster.
