Detailed Description

Objects, advantages and features of the present invention will be illustrated and explained by the following non-limiting description of preferred embodiments. The embodiments are merely exemplary for applying the technical solutions of the present invention, and any technical solution formed by replacing or converting the equivalent thereof falls within the scope of the present invention claimed.

The invention discloses a reverse tricycle, which comprises a main support 9, two front wheels 92 and a rear wheel 93, wherein the two front wheels 92 and the rear wheel 93 are respectively positioned at the front side and the rear side of the main support 9, a T-shaped support 96 is arranged at the front end of the main support 9, and the two front wheels 92 are respectively and symmetrically arranged at the two sides of the T-shaped support 96. The main support 9 is approximately vertically provided with a head support tube 13 and a cushion rod 94, and a cushion 95 is installed on the cushion rod 94. The vehicle head support tube 13 is provided with a vehicle head 1, and the vehicle head 1 comprises a faucet handle 11 and a brake 12. The head support tube 13 is approximately perpendicular to the main support 9 and is fixed relative to the main support 9. Of course, when the tricycle is in a foldable style, the head support tube 13 and the main support 9 can be folded relatively. The head support tube 13 is used for supporting the head 1 and is provided with a telescopic tube 16 in a sliding manner and a steering tube 14 in a rotating manner, and the telescopic tube 16 is fixed or loosened with the steering tube 14 through a fastener 18. The top end of the telescopic pipe 16 is provided with a faucet handle 11. As in the prior art, rotation of the faucet handle 11 rotates the steering tube 14. The bottom end of the steering tube 14 is provided with a rotating plate 15. The steering tube 14 and the rotary plate 15 form in combination the rotary drive of the invention.

A connecting rod type steering connecting mechanism is arranged between the T-shaped support 96 and the front wheel 92, the steering connecting mechanism comprises the rotary driving piece and symmetrically arranged pull rods 21 driven by the rotary driving piece, one end of each of the two pull rods 21 is respectively fixed on a driving piece 22, each driving piece 22 comprises a pivot 23, and the pivot 23 is arranged on the T-shaped support 96.

Specifically, as shown in fig. 4 and 5, the driving plate 22 includes a first pivot hole 221, and the pivot 23 passes through the first pivot hole 221 and is disposed on the T-shaped bracket 96; the driving plate 22 further comprises a second pivot hole 222, the front wheel shaft 17 passes through the second pivot hole 222 and penetrates into the front wheel 92 to enable the front wheel to rotate around the front wheel shaft 17; the driving plate 22 further includes a third pivot hole 223, and the pull rod 21 is hinged in the third pivot hole 223. The driving plate 22 includes two first pivot holes 221, the T-shaped bracket 96 is located between the two first pivot holes 221, and the second pivot hole 222 and the third pivot hole 223 are located on the same side of the axis X formed by the two first pivot holes 221.

The driving plate 22 further comprises a first fixing hole 224 for fixing the front wheel brake piece 19; the driving plate 22 further includes a second fixing hole 225 for fixing the front wheel fender 20.

The opposite ends of the symmetrically arranged pull rods 21 are all pivoted on the same connecting piece 24. The connecting piece 24 is a symmetrical two-half structure which is inserted into each other, and the opposite ends of the symmetrically arranged pull rods 21 are respectively pivoted on one half of the two-half structure; the two half structures are spliced together through a round pin 25; the rotating plate 15 of the rotary driving member is erected on the connecting member 24, and both ends of the round pin 25 extend into the rotating plate 15.

As shown in fig. 2, the ground height of the end of the pull rod 21 pivoted to the connecting member 24 is smaller than the ground height of the end of the pull rod 21 pivoted to the driving piece 22, and the two have a height difference H. When the faucet handle 11 is rotated to rotate the steering tube 14, the rotating plate 15 is rotated at the same time. Since the swivel plate 15 is fixed relative to the connecting member 24, the connecting member 24 is also rotated substantially about the axis of the steering tube 14, and the tie rods 21 on both sides of the connecting member 24 are pulled or pushed. Taking fig. 4 as an example, when the tricycle needs to turn left, the pull rod 21 in the figure pushes the front wheel 92 to rotate, and specifically, when the pull rod 21 receives a pushing force, the driving plate 22 receives a pushing force due to the pivot 23, so that the driving plate 22 rotates counterclockwise in the figure around the axis X. Since the second pivot hole 222 and the third pivot hole 223 are located on the same side of the axis X, a left turn of the front wheel 92 will occur. Likewise, the other front wheel 92 will turn left under the tension of the other tie rod 21. At this moment, the wheels will roll left first when turning left due to certain friction and height difference H between the wheels and the ground, so that the vehicle turns more smoothly. The same principle and the opposite force are applied to the right-hand turn of the vehicle, and the description thereof is omitted.

The main bracket 9 is also provided with a battery bracket 91, so that the tricycle can be an electric tricycle.

Of course, in other embodiments, the folding frame can also be connected with a front wheel mechanism and a rear wheel mechanism of a common bicycle to form the common bicycle.

The invention has various embodiments, and all technical solutions formed by adopting equivalent transformation or equivalent transformation are within the protection scope of the invention.
