Problems solved by technology

This will inevitably lead to two situations: one is because this speed follow-up ignores the sense of load force of the person, and at the same time, the person loses his own sense of load force and speed, so the speed is out of control, which in turn causes driving out of control and leads to traffic accidents, especially It is caused by high current work at high speed and damages the battery; the second is because of the inconvenience or unaccustomed driving caused by the former reason, and at the same time, the "assist" function of the electric vehicle can be completely replaced by its main function ("electric" gear), so this The "assist" function is simply idle

Embodiment Construction

[0016] In the installation diagram of the tension sensor shown in Fig. 1: the tension sensor (1) is installed in a proper position on the bicycle rear wheel fork beam (3), and the installation position is the tension sensor (1) and the upper part of the bicycle chain (2) Alignment engagement shall prevail.

[0017] In the front view of the tension sensor structure (lateral) shown in Figure 2: On the upper end of the elastic strain connector (1.1), the force wheel (1.2) is installed through the axle assembly (1.3), and the lower end is fixedly connected to the connecting seat and installed Clamp (cover) (1.4); the connecting seat and installation clamp (cover) (1.4) and the installation clamp (bottom) (1.5) are fastening clamps that fit up and down, and are used to connect with the bicycle rear wheel fork during installation. The frame beams (3) (Figure 1) are tightly matched.

[0018] In the left view (partial) of the tension sensor structure shown in Figure 3: at the simmering be...

Abstract

The invention relates to a detection method of pedaling moment by both feet of a rider. Particularly, a foot pedaling moment detection device is arranged at a proper position of a back underbeam of a bike and a convex side strain foil is closely attached to the side wall of the core of a convex side strain foil chamber rebound strain connecting body of the device; and a concave side strain foil is closely attached to the side wall of the core of a rebound strain connecting body of a concave side strain foil chamber. Through a driving chain of the bike, the pedaling moment when both feet of the rider tread for driving is sensed to the device in the form of a tension signal. The device then converts the tension signal into an electric signal through the conduction structure of the rebound strain connecting body and the convex and concave strain foil, and finally the electric signal is transmitted to a controller after amplified by a differential amplifier.

Description

Technical field [0001] The invention relates to an electric bicycle control technology. Background technique [0002] Electric vehicles are being welcomed by people as environmentally friendly, civilized, green and pollution-free vehicles with no exhaust, no noise, and resource-saving vehicles that do not consume non-renewable resources and save public space. In addition, the electric bicycle also has a "assistance" function with a "assistance" gear, which makes it easy for people to ride and drive, which not only meets the needs of long-distance travel, but also meets the needs of exercise. However, the current "assistance" function of electric bicycles is not an essential boost, but a speed follow-up. It controls the speed of the motor by detecting the speed of the chain disc. The rider's feet play the role of a given speed, and the pedaling force of its feet has nothing to do with the running of the car. That is, the electric motor is the main force for humans, not "assistance...
