New description: [New technical field] This creation is about an electric assist bicycle, especially a pedal that can sense the pedaling force. 5 [Prior Art] According to the impact of rising oil prices, energy-saving vehicles have become the focus of the public. Among them, electric-powered electric bicycles have the advantages of pollution-free and low energy consumption. Electric assist bicycles, whether used for fitness, leisure or short-distance transportation, have become increasingly popular in the 10 market. Generally speaking, the electric assist bicycle determines the size of the motor power supply according to the user's pedaling force and the power assist ratio mode set by the system, so the bicycle assisting bicycle must be equipped with a pedaling sensing system to sense the user's pedaling force. In the conventional technique, the industry mainly installs various sensors on the drive gear or the rear wheel axle to sense the gear speed or the bearing pressure of the axle, and then converts it into a sensing signal to the control system. Decide on motor power. However, the above sensing mode still has some disadvantages. In terms of sensing the rotational speed of the driving gear, when the user does not apply any pedaling force, the driving gear will continue to rotate, and the user will suddenly When the accident is not stepped on the bicycle, the system will not immediately stop the power supply of the motor, and the valley is easy to cause danger. On the other hand, in terms of the pressure of the sensing axle, the mechanical structure of the installation is relatively complicated. It is also inconvenient to repair the ground; therefore, there is still room for improvement in the conventional skills. M338806 [New Content] > The main purpose of 乍 is to provide a pedal that can sense the pedaling force, which can improve the safety of electric bicycle riding. New Zealand's secondary goal is to provide a pedal that can sense the pedaling force, and the simple structure can improve the convenience of subsequent maintenance and replacement. In order to achieve the goal of __, this creation provides a kind of sensible stepping. The Ilf series 1 is set on a foot-driven transmission mechanism of an electric assist bicycle.

This creation is a partial exploded view of the preferred embodiment. The drawings are a partial schematic representation of a preferred embodiment. 5 20 M338806 5 15 First of all, this creation is a pedal that can be used to sense the pedaling force. It is mounted on the body of a bicycle (not shown). It consists of a battery, a drive motor, a master and a pedal drive. . The battery is used to provide the power required by the bicycle, and the main controller is electrically connected to the battery and the driving motor to control the power output of the driving motor. The foot pedal transmission mechanism is disposed at the bottom of the vehicle body, and the bearing user thereof The pedaling force drives the crank (not shown) to rotate, and the crank is a concentric composite-toothed disc set (not shown). The sprocket set is composed of several sprocket fish and strips, which are also connected. The motor is used to allow the crank to rotate under the pedaling force, or the main controller can control the driving motor to output power to advance the bicycle. Further, the pedal of the creation is applied to the crank for (4) to step on, please refer to the 4th mechanism plate including the shaft 丨., - Circuit 2 Figure 1 to 2 'The pedal body 40 The sensing group 30 and the one shaft 1G are connected to the curve of the foot pedal transmission mechanism, the moving crank rotates 'the shaft 1 〇 is opposite to the curved end 2, the socket portion 12. 4 is provided with a circuit module 20 The system is sleeved on the shaft 1 〇, and a microprocessor (not shown), the power supply member 22 is used in the present embodiment, and the power supply member 22 and the motor ' are used in the shaft 1G to utilize the shaft 1Q = Xiao plastic. The power generation 'microprocessor is electrically connected to the power supply unit 22, and the rotation is carried out to transmit the transmission unit', and the signal generated by the microprocessor can be transmitted and the power output of the wireless advanced control motor is controlled; ^] 5 main controller 'in the embodiment 22 is modularized design and combined into a source 6 20 M338806 magnetic parts I system: I:: sex 32, - base 34 and two magnetic sensing pieces 36' The 322 is composed of a plurality of magnets 324, and the collar 322 has a sleeve portion 12 of a cylindrical shape, and the magnets 324 are disposed on the shaft 10 as the shaft 10 rotates.
