Problems solved by technology

Yet traditional mount type bicycle can't satisfy the needs of above-mentioned these development trends far away
[0003] There are many defects in traditional saddle type bicycles in aerodynamics, human anatomy, human biology, hemodynamics and ergonomics: 1, because the rider's upper body sits upright on the saddle, the windward area is large, Air resistance becomes the main factor affecting efficiency and driving speed; 2. The upright sitting posture increases the compressive strength of the human spine; 3. In order to reduce air resistance, the rider has to bend his upper body on the handlebars, which This posture of upper body bending increases the pressure on the abdomen and causes high compression on the lumbar spine; 4. From the point of view of hemodynamics, the riding style is not good for the return of venous blood in the lower limbs; The buttocks bear and produce strong friction with the saddle, making the buttocks feel uncomfortable and prone to many side effects
In addition, none of the above-mentioned technical solutions provides the possibility of body position change for the rider, which is very unfavorable for long-distance riding, and the above-mentioned several technical solutions do not have fitness functions

Embodiment 1

[0058] Example 1: figure 1 and figure 2 The first embodiment of the prone bicycle of the present invention is shown, and the prone bicycle comprises a vehicle frame 1, a front wheel 2, a rear wheel 3, a transmission mechanism 4 for driving the rear wheel 3, and a transmission mechanism 4 for driving the transmission mechanism 4. The pedaling mechanism 5, the front wheel 2 and the rear wheel 3 are respectively arranged on the front and the rear of the vehicle frame 1, the front of the vehicle frame 1 is provided with a forearm support mechanism 6, and the pedaling mechanism 5 and the vehicle frame 1 are provided with a Knee dynamic support mechanism 7 that moves synchronously with stepping on mechanism 5. We have found through the analysis of the prior art that it is difficult to satisfactorily solve the support problem of the rider's body in the prone position only by relying on static support. The present invention is based on human anatomy, bionics and ergonomics, and care...

Embodiment 2

[0062] Example 2: image 3 and Figure 4 The second prone bicycle embodiment of the present invention is shown. This embodiment is basically the same as Embodiment 1, the only difference being that the knee dynamic support mechanism 7 includes a pair of swing bars 71, A pair of connecting rods 72 and a pair of knee support pads 73, the upper ends of each swing rod 71 are hinged on the middle and upper part of the vehicle frame 1, one end of each connecting rod 72 is hinged with the lower end of the swing rod 71, and the other end is hinged with the crank 51, and is located in the active position. The fork 71, connecting rod 72 and crank 51 on the same side of the sprocket wheel 42 form a set of crank rocker mechanism, and each knee support pad 73 is suspended and installed on the middle part of the connecting rod 72 by a support 74. The length is longer, and the middle part is provided with a plurality of adjustment holes, so that the position of the knee support pad 73 can b...

Embodiment 3

[0064] Example 3: Figure 5 and Figure 6 The third prone bicycle embodiment of the present invention is shown. This embodiment is basically the same as Embodiment 2, the only difference being that the knee dynamic support mechanism 7 includes a pair of swing bars 71, A pair of connecting rods 72 and a pair of knee support pads 73, the upper ends of each swing rod 71 are hinged on the middle and upper part of the vehicle frame 1, one end of each connecting rod 72 is provided with a U-shaped connector 721, and the U-shaped connector 721 is connected to the pedal The rotating shaft of 52 is hinged, and the other end of each connecting rod 72 is also provided with a U-shaped structure, and is hinged with the lower end of the swing rod 71 through the U-shaped structure. One set of crank rocker mechanism, each knee support pad 73 is installed in the middle part of connecting rod 72 by a seat 74, and the bearing fulcrum of knee support pad 73 and support seat 74 is positioned at th...

Abstract

A prone bicycle comprising a frame (1), a front wheel (2), a rear wheel (3), a drive mechanism (4) for driving the rear wheel (3), and a pedal mechanism (5) for driving the drive mechanism (4), in which, the front wheel (2) and rear wheel (3) are mounted on the front portion and rear portion of the frame (1), wherein: a forearm support member (6) is mounted at the frame (1) front portion, and a dynamic knee support member (7) having synchronous movement with the pedal mechanism (5) is mounted between the pedal mechanism (5) and the frame (1). Designed with multi-point dynamic and static supports, this prone bicycle improves riding comfort and efficiency and is combined with crawling fitness function.

Description

technical field [0001] The invention relates to a bicycle, in particular to a prone bicycle. Background technique [0002] Today, bicycles are gradually developing from a means of transportation to sports, leisure and entertainment, and tourism, and there is also a trend to further develop towards fitness bicycles. Yet traditional saddle type bicycle can't satisfy the needs of above-mentioned these development trends far away. [0003] There are many defects in traditional saddle type bicycles in aerodynamics, human anatomy, human biology, hemodynamics and ergonomics: 1, because the rider's upper body sits upright on the saddle, the windward area is large, Air resistance becomes the main factor affecting efficiency and driving speed; 2. The upright sitting posture increases the compressive strength of the human spine; 3. In order to reduce air resistance, the rider has to bend his upper body on the handlebars, which This posture of upper body bending increases the pressure...
