Embodiment 1

[0012] Example 1: see figure 1 . The bottom of the front fork 2 is equipped with the front wheel 12 and the drive mechanism 1, the top is equipped with the seat 6, and the middle part is located in the steering tube 3 and can rotate therein. The steering tube is connected with the vehicle frame 9 through a pin shaft 10 . The lower end of the vehicle frame is equipped with a rear wheel 8, and a shock absorber 7 is provided between the top of the vehicle frame and the steering tube. Both sides of seat are provided with driving handle 4, and the lower end of driving handle is installed on the steering pipe. The backrest of the seat is provided with a cart handle 5. The driving mechanism can utilize the expansion and contraction of the air rod spring 11 to swing on the front fork, so that it is convenient to push the cart in the folded state, see figure 2 .

Embodiment 2

[0013] Example 2: see image 3 . The vehicle frame is provided with a gear box 13, and the driving handle is connected with the gear in the gear box in a swinging manner, and the gear box is connected with the flywheel 16 of the rear wheel through an output sprocket 14 and a chain 15. Swing the ride handle up and down or back and forth to turn the rear wheels.

Embodiment 3

[0014] Embodiment 3: see Figure 4 . The bottom of the seat is provided with a standpipe 19 , and the standpipe and the front fork are installed on the vehicle beam 17 with respective steering tubes, and the two are connected in a hinged manner through a pull rod 20 . Front wheel and drive mechanism are housed on the front fork. The rear end of the car beam is equipped with two rear wheels. The two rear wheels are installed on the vehicle beam through the vehicle frame and pin shaft 10, and can swing forward and backward relative to the vehicle beam. The vehicle frame is connected with the lower end of the vertical tube of the vehicle seat in a hinged manner through the rear tie rod 18. When the seat rotates, it can drive the front wheels to turn and the two rear wheels to swing back and forth. Steering rollover improves steering stability.

[0015] For vehicles with rear three-wheel structure, each rear wheel can be provided with a set of independent swing drive mechanism...

Abstract

The invention relates to a seat steering bicycle. A seat is connected with a front fork and is arranged on a bicycle frame by a steering pipe, and the seat and the front fork can turn in a linkage manner; a front wheel and a driving mechanism are arranged on the front fork, and a rear wheel and a traveling handle are arranged on the bicycle frame; when the bicycle is ridden and turned, the traveling handle is gripped and pushed, and a human body and the seat can turn and drive the front fork, the front wheel and the driving mechanism to turn in a linkage manner; the driving force is internal force of the steering system, does not work on the steering operation and cannot disturb the travelling direction of the vehicle; a pushing handle is also arranged on the seat, and when the bicycle is pushed, the seat or the pushing handle on the seat can be used as a handlebar to control the direction. The technical scheme solves the difficulty that the bicycle front wheel driving force can disturb the steering operation, and can effectively improve the driving safety of the bicycles.

Description

technical field [0001] The invention belongs to bicycles and power-assisted bicycles thereof. Background technique [0002] Front-wheel-drive bicycles often use a seat-style riding method. The backrest of the seat can support the forward pedaling force so that the pedaling force can be greater, making cycling easier and labor-saving. However, the driving force at this time will interfere with the steering of the front wheels, causing the handlebars to swing left and right as the left and right feet are pedaled, resulting in difficult control and unstable driving, especially at high speeds, it is easy to fall down, which brings safety hazards to the rider. . Contents of the invention [0003] Purpose of the present invention is exactly in order to solve above-mentioned deficiency, provides a kind of driving force does not influence the front-wheel drive bicycle that front-wheel turns to, and on this basis provides a kind of all-wheel drive bicycle that manually drives rear...
