Description

Power-assisted bicycle saddle

Technical Field

The utility model relates to the technical field of bicycles, in particular to a power-assisted bicycle seat.

Background

The saddle of the bicycle known at present serves as a single accessory for the bicycle carrying function, being the seat of the cyclist, without any other function.

The comfort of a bicycle seat depends on the softness of the bearing surface of the seat and the shape of the seat. In terms of the shape of the saddle, the wider the saddle reduces the pressure applied to the rider's hips, but the wider the saddle increases the friction between the rider's hips and inner thighs and the surface of the saddle, which can easily be damaged when the rider is riding for too long or is pedaling too fast. Therefore, for example, mountain bikes, road bikes and other racing bikes can adopt a design mode with a narrow appearance to reduce friction, but the pressure born by the buttocks of a rider is increased inevitably. People who are not familiar with the narrow saddle are worried about mountain bike and road bike.

When the utility model is used specifically:

the core of the utility model is the support assembly, facing different user groups, the saddle body, the support assembly and the finger-dialing assembly can adopt various combination modes. The upright post end is inverted V-shaped, when the saddle body swings to a certain amplitude, the seat bow can touch the upright post end, so that the swing amplitude of the saddle body is limited, and the swing amplitude can be limited at different angles by adjusting the relative position and angle of the bracket assembly and the saddle body. The finger poking device can control the sliding block to move up and down at the end of the sliding rail, and when the sliding block moves to the top, the top of the sliding block can be just embedded between the first seat bow and the second seat bow, so that the swing function of the saddle body is closed. In addition, the height of the sliding block at the end of the sliding rail is adjusted through the finger-poking device, and the swinging angle of the saddle body can be controlled.

The assistance function principle of the utility model is as follows:

the boosting function of the utility model is realized by fully utilizing the gravitational potential energy of the upper half of the rider by changing the gravity center position of the rider. The rider can have a tendency to sway from side to side due to the up and down movement of the legs of the rider during riding, but the conventional bicycle seat limits the expansion of the tendency. By utilizing the bicycle pedal, along with the up-and-down movement of the legs of a rider during pedaling, the upper body of the rider can also swing freely along with the bicycle seat, the gravity center of the upper body of the rider is shifted to one side by swinging, when the gravity center of the upper body of the rider deviates from the center line of the bicycle, the gravitational potential energy of the upper body of the rider is finally transmitted to the legs by the body, the legs press the bicycle pedals to finally convert the gravitational potential energy of the upper body of the rider into the kinetic energy for the bicycle to move forwards, and the swinging function of the bicycle seat realizes the power assisting of riding, so that the riding is more labor-saving.

According to practical tests of an applicant, on a conventional urban road surface, a rider using the bicycle seat with the normal riding speed of 20km/h under the condition that the swinging function is closed can increase the riding speed to 24km/h under the condition that the swinging function of the bicycle seat is opened, namely the riding speed can be increased by 20%. The power assisting effect of the bicycle seat is more obvious when the bicycle seat is tested on an uphill road section.

Other functions of the utility model:

when the bicycle seat is used, the swinging of the bicycle seat body reduces the friction between the bicycle seat bearing surface and the buttocks and the inner sides of thighs of a rider, and the bicycle seat bearing surface can be designed in a mode of soft materials with wider area no matter what type of bicycle is. The bicycle saddle of the utility model can improve the riding comfort of the rider no matter how long the riding time is or not and no matter how fast the rider pedals at a high frequency.

In conclusion, the bicycle seat has the advantages of stable structure, convenience in installation and simplicity in use, the saddle body can swing along with the body of a rider, the friction force between the bearing surface of the saddle and the buttocks and the inner sides of thighs of the rider can be effectively reduced, the gravitational potential energy of the upper half of the rider can be fully converted into the advancing kinetic energy of the bicycle, and the power assisting effect is achieved.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
