Problems solved by technology

In view of the shortcomings of traditional bicycles that are laborious to ride and long-term sitting affects health, there are currently some bicycles that can save labor and achieve physical exercise, but these bicycles do not have corresponding speed regulation mechanisms, and it is difficult to adjust the speed when riding, which increases the Because the speed cannot be adjusted to bring risks to riding, when the riding speed is too fast, it is easy to pose a threat to the physical and mental health of the rider

Embodiment 1

[0036] Such as figure 1 As shown, a speed-adjustable labor-saving bicycle includes a front wheel assembly 1, a rear wheel assembly 2 and a vehicle frame 3, and the front wheel assembly 1 and the rear wheel assembly 2 are respectively installed at the front and rear ends of the vehicle frame 3 .

[0037] Specifically, the front wheel assembly 1 and the rear wheel assembly 2 are conventional bicycle wheel structures, both including a wheel axle, spokes, rims and tires, the tires are fixed on the rims, and the rims are fixed on the wheel axles through the spokes. The vehicle frame 3 is a tripod. The stability of the triangle ensures that the overall structure of the bicycle is firm and reliable. The top of the front end of the vehicle frame 3 is fixed with a handle 26 .

[0038] It also includes a four-bar linkage mechanism, a sprocket 4, a chain A5 and a transmission mechanism for converting the rider's own weight into a swing force, the four-bar linkage mechanism is installe...

Embodiment 2

[0053] Such as figure 2 As shown, the difference between this embodiment and Embodiment 1 is that the transmission mechanism also includes an intermediate flywheel 18, a rotating shaft extends vertically at the rotational connection between the pedal 9 and the vehicle frame 3, and the intermediate flywheel 18 is fixedly sleeved on the rotating shaft , Flywheel B15, middle flywheel 18 and flywheel C17 are connected by chain B16 transmission.

[0054] Specifically, when riding, the size of the output torque can be adjusted directly by adjusting the position of the slider 11 relative to the output link rod 6, thereby completing the adjustment of the speed. The slider 11 slides arbitrarily on the output link rod 6 to ensure the speed The adjustment can be stepless speed regulation, which is more suitable for the rider's needs.

Embodiment 3

[0056] Such as image 3 As shown, the difference between this embodiment and Embodiment 1 is that the transmission mechanism includes a chain C23, a chain D24, a flywheel E20, a flywheel D22, a transition flywheel 19 and an intermediate chain plate 21, and the rotational connection between the pedal 9 and the vehicle frame 3 There is a rotating shaft extending vertically. The transition flywheel 19 is sleeved on the rotation shaft. The intermediate chain plate 21 is arranged coaxially with the transition flywheel 19 and is fixedly connected to the outer disc body of the transition flywheel 19. The flywheel E20 is fixedly connected coaxially with the flywheel A13. The flywheel The diameter of E20 is larger than the diameter of flywheel A13. Flywheel E20 is connected to transition flywheel 19 through chain C23. The middle chain disc 21 is connected to flywheel D22 through chain D24. Flywheel D22 is connected to rear wheel assembly 2. The diameter of flywheel E20 is larger than th...

Abstract

The invention discloses a labor-saving bicycle with adjustable speed. The labor-saving bicycle with the adjustable speed comprises a front wheel assembly, a rear wheel assembly and a frame; the frontwheel assembly and the rear wheel assembly are correspondingly mounted at the front and rear ends of the frame; the labor-saving bicycle with the adjustable speed is characterized by further comprising a four-connecting-rod mechanism used for converting the deadweight of a rider into a swinging force, a chain wheel, a chain A and a transmission mechanism; the four-connecting-rod mechanism is mounted on the frame; the chain wheel is mounted on the frame in a rotatable manner and engaged with the middle part of the chain A; the chain wheel is connected with the rear wheel assembly through the transmission mechanism in a transmission manner; one end of the chain A is connected to an output connecting rod of the four-connecting-rod mechanism in a sliding manner; one end, connected with the frame, of the output connecting rod extends to form a bending part; the other end of the chain A is connected with the bending part; and a tensioner for tensioning the chain A is arranged between the bending part and the output connecting rod. According to the labor-saving bicycle with the adjustable speed, the speed can be simply and rapidly adjusted to protect physical and psychological health of the rider.

Description

technical field [0001] The invention relates to the technical field of bicycles, in particular to an energy-saving bicycle with adjustable speed. Background technique [0002] The driving of traditional bicycles is almost all completed by people pedaling for rotational motion. As we all know, manpower stepping on the pedals for circular motion not only has a deadly dead point that causes "powerful and powerless" phenomenon, but also the driving efficiency is extremely low even near the dead point, which causes a lot of waste of limited manpower. . With the pluralistic development of society, bicycle is not only a means of transportation, but also a kind of fitness tool and sports competition equipment, or a kind of amusement toy and so on. In view of the shortcomings of traditional bicycles that are laborious to ride and long-term sitting affects health, there are currently some bicycles that can save labor and achieve physical exercise, but these bicycles do not have corr...
