Abstract

The invention relates to a teeterboard-driven trishaw. The teeterboard-driven trishaw is that a front wheel is about 10cm in length, and two rear wheels are about 25cm in diameter; a beam is arranged between a steering axle sleeve of the front wheel and rear wheel axles; a board is arranged on the beam; a handle above a vertical lock on the upper surface of the front wheel steering axle shaft can be folded and turned back; when a traction handle is backwards overlapped, the carrying is convenient; a steering handle head of the trishaw can be vertically locked; the rear wheels are two bicycle rear wheels provided with fly wheels and mounted on the same rear axle; the two fly wheels are mounted at the inner sides of the rear wheels and both have the function of driving the wheels to move forwards in one direction; teeth of the two fly wheels are tapered rather than quadrangular; arc-shaped racks of which the top and bottom are provided with the tapered teeth engage with the tapered teeth of the fly wheels, wherein the arc-shaped racks are arranged at two ends of a teeterboard which rotates around the beam; the teeterboard can rotate up and down within 15 degrees; when the trishaw is used as a luggage barrow, the rear wheel axles and the teeterboard are provided with tilting stopping type horizontal inserting pins. The teeterboard-driven trishaw needs a small space, and is small in size and light in weight.

Description

The trishaw that seesaw drives

Technical field

The invention belongs to human powered vehicle technical field, relate to a kind of manpower pedal three-wheel vehicle.

Background technology

Existing manpower pedal three-wheel vehicle generally has saddle, pedal wheel and chain, and the space shared by such three-wheel vehicle is large, and volume is large, and vehicle body weight, can not fold, and is not easy to carry with, and also uncomfortable cooperation baggage car uses.

Summary of the invention

The technical problem to be solved in the present invention is, provides one not have saddle, does not have the seesaw of pedal wheel and chain to drive trishaw, it takes up room little, and volume is little, and vehicle body is light, folded after the front folding of energy, easily carry with, work as walking-replacing tool at the Shi Jike that goes out and can work as again baggage car use.

The technical scheme that the present invention takes is: before this trishaw, wheel diameter is at about 10cm, rear two wheel diameters are at about 25cm, it is car beam between front-wheel steering axle sleeve to hind axle, car beam there is sweep, the above handlebar of upright lock above front-wheel steering axle sleeve can be turned back forward, works as tow handle, stacks backward, be easy to carry, erect the direction labour contractor that locking is three-wheel vehicle; Trailing wheel is that the trailing wheel of two bicycle band flywheels is arranged on same rear axle, two flywheels are all arranged on the inner side of trailing wheel, and two flywheels all have the unidirectional function driving forwards wheel and advance, the teeth of two flywheels are not four rib teeth, circular cone teeth, engage with flywheel circular cone teeth be rotate around car beam stick up the arc-shaped rack of pedal two ends up and down with circular cone teeth, the rotation amplitude of seesaw is between upper and lower 15 ° of angles, when baggage car uses, axletree of rear wheel and seesaw have only lifts up horizontal pin.

After adopting above technical scheme, this three-wheel vehicle front and back wheel diameter is little, so its volume is little, because there is no saddle, there is no pedal wheel and chain, so it occupies little space, because handlebar can be turned back forward, so the tow handle can working as baggage car uses, because handlebar can fold back, so easy to carry, because handlebar head can uprightly be locked, people stands on seesaw and just can advance voluntarily with foot-operated turning, so can walking-replacing tool be worked as, because of seesaw with car beam for fulcrum, so one, two, left and right pin presses down a rising, can driven; Both lain fallow satisfied, tempered again health; Only lift up horizontal pin because seesaw and axletree have, when baggage car uses, plug this latch, loading area can be increased again.

Accompanying drawing explanation

Fig. 1 is the plan structure schematic diagram of the trishaw that seesaw of the present invention drives.

Fig. 2 is the seesaw backsight structural representation of the trishaw that seesaw of the present invention drives.

In figure: 1, front-wheel; 2, trailing wheel; 3, Che Liang; 4, sweep; 5, handlebar; 6, brake handle; 7, flywheel; 8, seesaw; 9, seesaw bearing carrier ring; 10, the arc-shaped rack of circular cone teeth is with; 11, seesaw only lifts up horizontal pin; 12, axletree of rear wheel.

Detailed description of the invention

Concrete structure of the present invention and service condition is described in detail below in conjunction with accompanying drawing.

Trishaw front-wheel (1) diameter that this seesaw drives is at about 10cm, rear two-wheeled (2) diameter is at about 25cm, car beam (3) between front-wheel (1) steering column jacket to hind axle (15), car beam (3) there is sweep (4), the above handlebar (5) of upright lock above front-wheel (1) steering column jacket can be turned back forward, works as tow handle, stacks backward, be easy to carry, erect the direction labour contractor that locking is three-wheel vehicle; Trailing wheel (2) is that the trailing wheel of two bicycle band flywheels (7) is arranged on same rear axle (15), two flywheels are all arranged on the inner side of trailing wheel (2), and two flywheels (7) all have the unidirectional function driving forwards wheel and advance, the teeth of two flywheels are not four rib teeth, circular cone teeth, engage with flywheel circular cone teeth be rotate around car beam stick up the arc-shaped rack of pedal two ends up and down with circular cone teeth, the rotation amplitude of seesaw is between upper and lower 15 ° of angles, when baggage car uses, axletree of rear wheel and seesaw have only lifts up horizontal pin.After adopting above technical scheme, this three-wheel vehicle front and back wheel diameter is little, so its volume is little, because there is no saddle, there is no pedal wheel and chain, so it occupies little space, because handlebar (5) can be turned back forward, so the tow handle can working as baggage car uses, because handlebar (5) can fold back, so easy to carry, because handlebar (5) head can uprightly be locked, people stands on seesaw and just can advance voluntarily with foot-operated turning, so can walking-replacing tool be worked as, because of seesaw with car beam for fulcrum, so one, two, left and right pin presses down a rising, can driven, both lain fallow satisfied, tempered again health, only lift up horizontal pin because seesaw and axletree have, when baggage car uses, plug this latch, loading area can be increased again.

Claims
