Technical Field

The invention relates to the technical field of bicycle accessories, in particular to a pedal power acquisition device.

background

In bicycle competitive sports, athletes need quantify the self condition and the state of riding of oneself in the training of riding, know the not enough of self to scientific training promotes, and before power detecting instrument appeared, does not have any means to quantify.

The power detection instrument is provided with a sensor sensing component on a pedal spindle or a pedal crank and the like to detect and analyze the force application intensity applied by a sportsman on a bicycle pedal and the force application condition of force distribution on the surface of the bicycle pedal, so that the sportsman can obtain continuous relevant data of whole-circle rotation to improve the pedaling efficiency of the sportsman, and better exercise and competition effects of the bicycle are achieved.

The current power detecting instruments for bicycles are divided into several types: a chain wheel dynamometer, a crank dynamometer, a middle shaft dynamometer and a pedal dynamometer. Wherein, the dental tray power meter can only detect the power on the dental tray, and can not distinguish the trampling power on the left foot and the right foot. The same is true of the center shaft power meter. The crank power score is a unilateral crank and a bilateral crank, wherein the bilateral crank can respectively and simultaneously detect the power of the left side and the power of the right side, analyze the power and quantify the strength difference of the left leg and the right leg of a person, and accordingly pertinently improve the power; however, due to the current development of bicycle history, the crank specification is diversified and personalized, and the crank is usually required to be customized for the power detection device of the crank. The pedal power meter is different, and bicycles are developed to the present, the screw interface reserved for the pedal is not changed, and 9/16 screw threads are made of English, so that a user can transplant to any one bicycle freely only by purchasing one pair of power detection pedals.

At present, the pedal dynamometer has a mode of detecting the surface force of a pedal and a mode of detecting the mandrel force of the pedal, wherein the mode of detecting the surface force of the pedal needs to carry out special treatment on the pedal, and because the plastic material can not be used for installing a strain gauge, the pedal material is limited, rigid materials are needed to be used for manufacturing the pedal, such as 6061 aluminum materials or stainless steel, the weight is generally heavy, and the bicycle competition has the necessary pursuit of per gram for the weight of a bicycle body. The detection on the spindle is much the same, so the power detection module is chosen to be located on the pedal spindle.

The power detection module generally comprises a strain type sensor for detecting force application information applied to a bicycle pedal by an athlete, a circuit board for processing data, a battery for supplying power and other electronic components.

Due to the limitation of space, the circuit board surrounding the mandrel is often in a circular ring shape, the circuit board is directly sleeved on the mandrel, the assembly is difficult, the disassembly is difficult, the maintenance is difficult, and even the power detection module produced by some manufacturers cannot be disassembled without worry. How to solve the technical problem is the technical problem that needs to be solved in the technical field of the existing bicycle accessories.
