Problems solved by technology

[0005] The installation of the mid-mounted motor on the market generally requires a special frame, otherwise it needs to be modified on the existing bottom bracket of the frame to make it suitable for the installation of the mid-mounted motor. This installation method is more difficult and requires Professional and technical personnel to operate, can not be DIY by the user
In addition, due to the limited space of the vehicle frame, it is limited to install a torque sensor with bilateral shaft torsional deformation in the middle shaft of the gearbox of the mid-mounted motor. Installed on the side of the central axis, it is a single-sided torque sensor

Abstract

The invention discloses a built-in motor applying dynamic transducer circuit combination. The built-in motor includes a driving device and a linkage device. The driving device drives the linkage device. The linkage device comprises a gearbox, a middle shaft and a protective sleeve. The gearbox is fixedly connected with a protection box. The middle shaft is placed in the protective sleeve. The middle shaft is provided with a torsion sleeve in a sleeved mode. The torsion sleeve is fixedly connected with the middle shaft. A transmitting feedback circuit is arranged on the inner wall of the protective sleeve. A receiving and collecting circuit is arranged on the torsion sleeve. According to the built-in motor, a bicycle rider can use a bottom bracket of a general vehicle frame (that is, a special vehicle frame is not required) to install the built-in motor applying dynamic transducer circuit combination in a DIY mode, and the general bicycle is refitted into an electric bicycle; and the built-in motor applying dynamic transducer circuit combination can also be used for mass production installation of electric bicycles manufacturing plants.

Description

technical field [0001] The invention belongs to the technical field of electric bicycles, and in particular relates to a mid-mounted motor using a combination of dynamic sensor circuits. Background technique [0002] Bicycles with auxiliary electric motors are usually equipped with front-wheel motors, rear-wheel motors, or mid-mounted motors, which are collectively referred to as "electric bicycles" or "eBicycles" or "eBikes". [0003] For the front and rear wheel motors, these are hub motors and are manufactured to form part of the front and rear wheels of the bicycle respectively. As for the central motor, it is part of the central axle drive system of the electric bicycle, which provides driving force for the electric bicycle by using power to drive the motor to rotate, and it is generally installed in the middle and lower part of the electric bicycle. [0004] Currently, the most practical way to mount a mid motor to a bicycle is through the bike's bottom bracket tube, ...
