Portable bicycle auxiliary power device

Abstract

The invention discloses a portable bicycle auxiliary power device, and relates to the technical field of bicycle auxiliary power devices. The portable bicycle auxiliary power device comprises a powermechanism and a control mechanism. The power mechanism comprises an auxiliary power device body. Sleeve rods are arranged at the positions, close to the two sides, of the auxiliary power device body and are internally provided with telescopic rods. One ends of the telescopic rods are provided with clamping blocks. The auxiliary power device body is provided with a holding clamp fixing frame. The holding clamp fixing frame is provided with an electron speed regulator and a gear motor. The gear motor is provided with a flexible friction wheel. The control mechanism comprises a potentiometer anda rotary knob accelerator switch. The rotary knob accelerator switch is mounted on the potentiometer. According to the portable bicycle auxiliary power device, brand new design is adopted, the weightof the portable bicycle auxiliary power device does not exceed 2.5 kg, and thus carrying is convenient and capable of saving labor; the portable bicycle auxiliary power device is located at the position, close to the top, of a rear wheel of a bicycle, a user cannot touch the portable bicycle auxiliary power device easily, and thus safety is high; the portable bicycle auxiliary power device is highin stability, and the problems of magnetism leakage, short circuit and the like cannot occur; and the portable bicycle auxiliary power device is convenient to mount and dismount, and the mounting anddismounting time does not exceed two minutes for a normal user.

Description

Technical field [0001] The present invention relates to the technical field of bicycle auxiliary power devices, in particular to a portable bicycle auxiliary power device. Background technique [0002] Existing bicycle auxiliary power devices are mainly divided into three categories: bicycle mid-mounted motors, front / rear hub motors, and bottom bracket motors. The central motor of the bicycle is an auxiliary power device that installs a geared motor on the axle where the pedals are located, detects the riding speed through a torque sensor, a speed sensor or a cadence sensor, and assists according to the speed. It is mainly used for power-assisted modification of mountain bikes and other cross-country bikes. The advantage of this power-assisting method is that the power transmission is delicate and direct, and the off-road power experience is good, but the bicycle needs to be specially modified. Since the power-assisted device is located on the axle where the pedals are located a...

Problems solved by technology

However, the assembly position of the device and the body frame of some models will interfere in structure, and it can only be adapted to some models; it is inconvenient to disassemble and assemble for ordinary people who are not strong in hands-on ability

The above three types of bicycle power assist devices all have different defects, which bring inconvenience to the daily use of users.
