[0023] (1) By adjusting the radius of the double chainrings and double small-diameter flywheels, the driving radius power arm is lengthened and the torque is increased, resulting in a labor-saving effect;

[0024] (2) By changing the radius of the dual small-diameter flywheels, the drive ratio of the driving wheel and the driven wheel is changed, so that the number of turns of the small-diameter flywheel per unit time is increased;

[0025] (3) By installing a set of extended tooth plates and a small-diameter flywheel, the resultant force generated by each chain is increased, the pulling force and torque per unit time are increased, the useful work is increased, and the stability is increased;

[0026] (4) By installing a telescopic long arm, the length of the power arm is increased and the torque is increased, which has a significant labor-saving effect per unit time;

[0027] (5) By setting the seat and the center axis of the double chainring to be vertical to the ground, two functions can be achieved: First, the vertical downward gravitational kinetic energy generated by the legs and the body weight during riding can be used to exert force on the pedals in each pedaling cycle, doing useful work to increase the torque, because, just like stepping in place and walking, stepping in place saves more energy than walking. Second, the distance between the legs and the pedals can be adjusted to the shortest, so that the maximum step-by-step pedaling cycle that is suitable for the body structure and within the range without discomfort can be performed correctly and accurately, providing advance conditions for the application of telescopic long-arm crutches. (6) By adding an electric automatic system, alternating rest during riding can be achieved, improving the efficiency of use. At the same time, the volume and weight of the power box and the motor box can be controlled within the minimum coefficient and the power can be set above the maximum coefficient value, so as not to change the basic characteristics of the bicycle.

DETAILED DESCRIPTION

[0033] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Example 1: Please refer to Figure 1 and 3 -4, a high-efficiency dual-purpose bicycle with double toothed plates that can increase speed and save effort at the same time and is fully electric and automatic, comprising a telescopic long-arm large crank 10, an enlarged toothed plate 11, a small-diameter flywheel 12, a steel ring gear 14, a motor gear box 15 and a power supply box 16;

[0035] The double enlarged chainplate 11 and the double small diameter flywheel 12 are respectively wound and meshed by double chains 34 to form a closed labor-saving cycle. The telescopic arm long handle 10 and the enlarged chainplate 11 are an integrated labor-saving structural component.

[0036] Specifically, Figure 1 and Figure 3-4 As shown, the double chain 34 is combined and wound in the structural order of the double chain plate 11 and the double small diameter flywheel 12, and the expanded chain plate 11 and the telescopic long arm large pedal 10 are an integrated structural component, and a folding pedal 9 is installed at the other end.

[0037] Example 2: Please refer to Figure 1 and Figure 4 , the steel ring gear 14 is set in the middle of the steel ring of the rear wheel 44 and hinged for one circle, and then protrudes on the outside, so that the force and friction force of the rear wheel 44 tend to be on the same straight line through the transmission path α48, so that the power arm (Rh) 49 is stretched as much as possible, and the length is slightly smaller than the resistance arm (R) 51, so that the power torque is increased, and the technical parameter requirements of saving effort and increasing movement stability are achieved, and the power saving and energy saving effect are obtained. At the same time, the motor gear box 15 is horizontally installed in the middle of the upper part of the steel ring gear 14, and the power box 16 is horizontally installed on the lower inner left side of the rear frame 19;

[0038] Specifically, Figure 1 and Figure 3 As shown, during operation, the dual motor gear clutch switch 36 is started to engage with the steel rim gear 14, and then the dual motor key switch 29 is started to drive the motor gear 36 to rotate and the rear wheel 44 steel rim gear 14 to rotate.

[0039] How it works

[0040] When the present invention is operated in bicycle mode, the user rides by independently selecting the use method of the foldable pedals 9. Since the extended chainring 11 increases the radius of the driving wheel, the rotation period frequency of the driven wheel small diameter flywheel 12 per unit time is increased, the wheel rolling frequency is correspondingly increased, and the torque is correspondingly increased; the telescopic long-arm cantilever 10 directly generates a labor-saving torque due to the lengthened power arm. The role of the telescopic long-arm cantilever 10 is that the rider performs striding movement during the riding movement, which is an aerobic exercise and is beneficial to the training of blood vessels, bones and muscles.

[0041] When the single chain 34 (single) is used for pulling, the power mass center of the transmission path α changes. Because the resistance arm R51 is longer and the resistance torque is larger, the gravity of the rear wheel will form an indeterminate force, which will produce a counterclockwise direction. The overturning moment is also generated by using a single chain 34 (single) to pull the work on the other side of the rear wheel. The center of mass changes and forms an unstable force, which also generates a counterclockwise rotation. However, when the double chain 34 is used for pulling, no counterclockwise overturning moment will occur. At this time, the two vertical forward pulling forces will produce the maximum combined force, and while increasing the force, the stability of the movement is also increased.

[0042] When switching the electric vehicle mode, the rider does not need to stop and get off the vehicle. The rider can first start the dual motor gear clutch 37, and then start the dual motor key switch 29 to drive the dual motor gear 36 to rotate and the steel ring gear 14 to rotate. At the same time, the dual gear drive can effectively increase the driving force efficiency.

[0043] When switching back to the bicycle mode, there is no need to stop the bicycle and get off the bicycle. First, the dual motor key switch 29 is turned off and then the dual motor gear clutch switch 37 is turned off to complete the switching.

[0044] Based on the above-mentioned operation embodiments, it is obvious to those skilled in the art that they are not limited to the details of the exemplary embodiments of the present invention, and that the present invention can be implemented with other specific technical solutions without departing from the spirit or basic features of the present invention. Therefore, no matter from which aspect, it is the result or logical extension result of the exemplary effect of the embodiment of the present invention. The present invention is based on physical science, on the principles and simulation practices of force decomposition and lever principle, etc., combined with the objective environmental conditions of real traffic scenes, and comprehensively considers the corresponding safety factor ratio formed between the mechanical structure and speed of a bicycle, and controls the total electric drive power design to be below 25 kilometers per hour as stipulated by the state to meet the technical requirements of the present invention.
