Embodiment 1

[0040] Such as figure 2 As shown, the transmission mechanism also includes an intermediate flywheel 17. The pedal 4 extends vertically with a rotating shaft at one end hinged with the vehicle frame 5. The intermediate flywheel 17 is fixedly sleeved on the rotating shaft. The second flywheel 15, the intermediate flywheel 17 and the second flywheel The three flywheels 16 are connected in transmission through the first chain 14 .

[0041] Such as image 3 and Figure 4 As shown, when riding, people sit on the seat 8 with their buttocks and put their feet on the pedals 4. The seat 8 supports the weight of the whole human body through the buttocks. The end of the rod 7 close to the seat 8 swings down, and the connecting rod 6 also moves downward, so that the pedal 4 rotates, thereby tilting upward. Rotation, thereby driving the sector gear 12 to rotate clockwise around the front end of the vehicle frame 5 as a rotating shaft, driving the first flywheel 13 to rotate counterclock...

Embodiment 2

[0043] Such as Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that the transmission mechanism includes the second chain 18, the third chain 19, the fifth flywheel 23, the fourth flywheel 22, the transition flywheel 20 and the middle chain plate 21, and the pedal 4 There is a rotating shaft extending vertically from the rotating joint with the vehicle frame 5. The transition flywheel 20 is sleeved on the rotating shaft. It is coaxially fixedly connected with the first flywheel 13, the diameter of the fifth flywheel 23 is greater than the diameter of the first flywheel 13, the fifth flywheel 23 is connected with the transition flywheel 20 through the second chain 18, and the middle chain disc 21 and the fourth flywheel 22 pass through The third chain 19 is connected in transmission, and the fourth flywheel 22 is connected with the rear wheel assembly 2 . The diameter of the fifth flywheel 23 is larger than the diameter of the middle chain disc 21...

Embodiment 3

[0047] Such as Figure 7 As shown, the difference between this embodiment and Embodiment 1 is that the rear wheel assembly 2 is provided with a second seat 24 , the second seat 24 is fixed on the vehicle frame 5 , and an armrest 23 is installed at the rear end of the seat 8 . When in use, both the second seat 24 and the seat 8 can carry people. When riding, the people on the second seat 24 hold the armrest 23 with their hands, and press up or down the armrest 23 to play a power-assisted role.

[0048] Specifically, the armrest 23 includes a handle portion and two connecting portions vertically connected to two ends of the handle portion, and the two connecting portions are respectively fixed on the seat 8 .

Abstract

The invention discloses a labor-saving bicycle. The labor-saving bicycle comprises a front wheel assembly, a rear wheel assembly, a handlebar, a pedal, a bicycle frame, a connecting rod, a swinging rod, a seat, and a transmission mechanism for transmitting swinging force of the swinging rod to the rear wheel assembly, wherein the front wheel assembly and the rear wheel assembly are mounted at thefront end and the rea rend of the bicycle frame respectively; the pedal is rotatingly mounted at the lower end of the middle of the bicycle frame; the swinging rod and the pedal are hinged to both ends of the connecting rod; the seat is fixed at the hinge end of the connecting rod and the swinging rod; one end of the swinging rod, which is away from the seat, is hinged to the front end of the bicycle frame and drivingly connected with the rear wheel assembly through the transmission mechanism. The labor-saving bicycle is powered by body weight of a rider to achieve labor-saving riding, so thatthe rider can achieve good exercise effects without riding through long-time foot movement and whole body action.

Description

technical field [0001] The invention relates to bicycles, in particular to a labor-saving bicycle. 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 has caused a lot of limited manpower. Big waste. 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. A bicycle that people use to pedal for rotating motion can only be pedaled while sitting, and sitting for a long time is unhealthy for the lower back and cannot achieve the fitness effect of whole-body exercise, but it is easy to cause adverse effects on some parts of the body. ...
