Problems solved by technology

However, in the process of riding, people can only step on the pedals from top to bottom. When one pedal runs to the highest point and the other pedal runs to the lowest point, the two pedals are at the dead point of force at the same time. The inertia of the pedal can pass over the area near the dead center of the force, which reduces the riding efficiency and makes riding more strenuous

Embodiment 1

[0046] A power-assisted bicycle that pedals upright upright, such as figure 1 As shown, it includes a vehicle frame 1 and two wheels 2 that are respectively connected to the front and rear sides of the vehicle frame 1, and a flywheel is coaxially connected to the wheel 2 located on the rear side of the vehicle frame 1. When in use, the vehicle frame 1 can be driven by the flywheel. The wheels 2 on the rear side rotate circumferentially to drive the bicycle to move forward.

[0047] like figure 2 As shown, the vehicle frame 1 is provided with a connecting shaft 1 , and the connecting shaft 1 3 is horizontally arranged and close to the seat cushion side of the vehicle frame 1 . The two ends of connecting shaft one 3 are respectively provided with upper sprocket one 4 and upper sprocket two 5, and upper sprocket one 4 and upper sprocket two 5 are all rotatably connected with connecting shaft one 3 through bearings. The vehicle frame 1 is also provided with a connecting shaft 2...

Embodiment 2

[0056] like Figure 5 , Image 6As shown, the difference between the second embodiment and the first embodiment is that a limiting cavity 1 32 is formed between two adjacent ratchet teeth 121 , and the depth of the limiting cavity 1 32 gradually changes along the circumferential direction of the lower sprocket 1 7 . The shallower side of the limiting cavity 1 32 is the connecting side 1 321 , and the deeper side of the limiting cavity 1 32 is the limiting side 1 322 . A supporting plate-33 is hinged on the connecting side-321, and the rotation axis of the supporting plate-33 is parallel to the rotation axis of the lower sprocket-7. Elastic part one 34 is arranged in the limit chamber one 32, and elastic part one 34 is connected with support plate one 33, and elastic part one 34 applies elastic force to support plate one 33, makes support plate one 33 and position limiting cavity one 32 mouth flush. In this embodiment, the first elastic member 34 is a compression spring. Th...

Abstract

The invention provides a power-assisted bicycle for stepping up and down upright, which includes a vehicle frame and wheels. Shaft 2, the connecting shaft 2 is provided with a lower sprocket 1 and a lower sprocket 2; a transmission chain 1 is connected between the upper sprocket 1 and the lower sprocket 1, and a transmission chain is connected between the upper sprocket 2 and the lower sprocket 2. Chain 2; connecting shaft 2 is provided with a driving wheel; a ratchet mechanism 1 is provided between the lower sprocket 1 and the connecting shaft 2; a ratchet mechanism 2 is provided between the lower sprocket 2 and the connecting shaft 2; a pedal is provided on the frame One and pedal two. The problem of the dead point of the force is solved by stepping upright, which has the advantages of constant transmission efficiency, reasonable force application, labor-saving riding, and high efficiency. A high-efficiency inclined double-roller worm gear transmission mechanism can be added to the bicycle, so that it can be driven by a high-speed working motor, and has the advantages of small size, high efficiency, power saving, and power assistance.

Description

technical field [0001] The present invention relates to a bicycle, in particular, to a power-assisted bicycle for pedaling up and down. Background technique [0002] At present, the existing bicycles are used to drive the bicycles to move forward by pedaling the bicycles in a circular motion. However, in the process of riding, people can only step on the pedals from top to bottom. When one pedal runs to the highest point and the other pedal runs to the lowest point, the two pedals are at the dead point of force at the same time. The inertia of the pedal can pass through the area near the dead center of the force, which reduces the riding efficiency and makes riding more strenuous. Contents of the invention [0003] In view of this, the object of the present invention is to provide a power-assisted bicycle that can be pedaled upright and upright, which has the advantages of no dead point, high riding efficiency, and relatively labor-saving riding. [0004] In order to sol...
