Description

TECHNICAL FIELD

[0001] The utility model relates to a bicycle seat cushion technical field, more specifically, the utility model mainly relates to a split type riding seat cushion and control method. BACKGROUND

[0002] The bicycle seat cushion is the bicycle accessory directly contacted with the hip during riding, and the bicycle seat cushion is usually designed into a fixed structure, and people can only keep the fixed sitting posture during riding, and the body will be very uncomfortable once the riding time is too long, the sitting bone pressure is concentrated during riding, and long time can easily cause the hip numbness and pain, especially the front part can compress the perineal part and affect the health. In addition, since the traditional bicycle seat cushion is made into a fixed type, once the road condition is poor, the seat cushion is affected by the impact force of the bumping and vibration, and the rider is often uncomfortable during riding because of the lack of proper buffering effect to absorb the vibration.

[0003] The existing design solves the problem by designing a split type passive rotating seat cushion, which is suitable for the up and down movement of the human body during pedaling the bicycle, reduces the compression of the perineal part, and can passively adjust the sitting posture to improve the comfort. However, the passive split type rotating seat cushion of the existing design can only passively rotate when a certain pressure is felt, and the force needs a transmission process, which can easily cause a small reaction force. If the reaction force is designed to be too small, it is easy to cause excessive rotation and instability of the center of gravity, which is not conducive to riding. Therefore, the design of the split seat cushion needs to be further improved. UTILITY MODEL CONTENTS

[0031] Furthermore, in some embodiments, such as Figure 2 As shown, in order to provide data parameters for recognizing different riding postures, rear pressure sensors 100 are respectively set on the inner rear end of the two pads 50. The two rear pressure sensors 100 are electrically connected to the PCBA board 80 through wires.
