Problems solved by technology

However, the existing mid-mounted motor is locked and fixed by multiple screws. This type of mid-mounted motor needs to be equipped with a customized frame, which cannot be easily switched between a bicycle and a power-assisted bicycle through installation and disassembly. The structure is relatively complicated, and higher production costs

Embodiment 1

[0026] See figure 1 and figure 2 , the present invention has a motor body 1, a clutch 6, an output center shaft 3 of the motor body 1, and a housing 2 locked on one side of the motor body 1 by bolts, one end of the clutch 6 protrudes from the motor body 1, and the inner motor The structure is the same as the internal structure of the coaxial central motor, which is the prior art, and will not be described in detail here. The motor body 1 is provided with a fixed assembly 4, which is arranged parallel to the motor body 1. The motor body 1 and the fixed assembly 4 are integrally connected through the base 12. The fixed assembly 4 is provided with threads, and the threads on the fixed assembly 4 cooperate with the lock. The tightening nut 5 fixes the motor body 1 below the bicycle frame, and an installation hole 61a is provided on the outer end cover of the motor body 1 protruding from the clutch 6 .

Embodiment 2

[0028] See Figure 4 The difference between this embodiment and Embodiment 1 is that, more specifically, the fixing assembly 4 is a hollow cylindrical beam whose outer diameter is the same as the inner diameter of the bicycle frame bottom bracket. The base 12 of the hollow cylindrical crossbeam is provided with an accommodating groove 41 matching the outer circumference of the bottom bracket. The length of the hollow cylindrical crossbeam is the same as the length of the bottom bracket on the bicycle frame. Internal threads, the outer circumference of the locking nut 5 is provided with external threads, the inner circumferential internal threads of the hollow cylindrical beam match the outer peripheral external threads of the locking nut 5, and the inner circumference of the locking nut 5 is an inner regular hexagon 51a , also can be other convenience screwdrivers such as square, regular pentagon to carry out the regular polygon of fixed operation, the setting of inner regular...

Embodiment 3

[0030] See Figure 5 The difference between this embodiment and Embodiment 1 is that, more specifically, the fixing assembly 4 is a hollow cylindrical beam whose outer diameter is the same as the inner diameter of the bicycle frame bottom bracket. The base 12 of the hollow cylindrical beam is provided with an accommodating groove 41 matching the shape of the outer circumference of the bottom bracket, the length of the hollow cylindrical beam is greater than the length of the bottom bracket on the bicycle frame, and the outer circumference of the hollow cylindrical beam is provided with external threads , the inner circumference of the lock nut 5 is provided with internal threads, the outer circumference of the lock nut 5 is a regular hexagon 51b, the inner threads of the lock nut 5 are matched with the outer circumference of the hollow cylindrical beam, and the locking The outer periphery of the nut 5 is set as a regular hexagon 51b to facilitate cooperation with a wrench, so ...

Abstract

The invention relates to a centrally-arranged motor. The centrally-arranged motor comprises a motor body, a clutch, an output center shaft of the motor body and a shell locked on one side of the motorbody through a bolt. A mounting hole is formed in an outer side end cover of the clutch, a fixing assembly is arranged on the motor body, and is parallel to the motor body, a thread is arranged on the fixing assembly, the fixing assembly is matched with a locking nut to fix the motor body to be below a bicycle frame, a bicycle with the centrally-arranged motor comprises the frame, a bottom bracket and a chain wheel, and the chain wheel is composed of a chain cover, a five-claw disc and a tooth disc which are connected in sequence. The defects existing in the prior art can be overcome, an assistance bicycle does not need to be independently purchased, the centrally-arranged motor of the simple structure is directly mounted on an original bicycle, and the bicycle can be switched to the assistance bicycle.

Description

technical field [0001] The invention relates to the field of power-assisted bicycle motors, in particular to a central motor and a bicycle equipped with the central motor. Background technique [0002] Power-assisted bicycles are a kind of bicycles, which use batteries as auxiliary power sources, and can realize the integration of human-powered riding and motor-assisted driving. The motor installation of the power-assisted bicycle is mainly divided into two types: the center and the hub. The middle motor is connected to the frame, and is connected to the rear wheel through the chain to transmit power. At the same time, there are pedals installed on both sides of the motor. Under certain circumstances, the rider can realize human-powered riding through the pedals, and the resistance is no different from that of a normal bicycle. However, the existing mid-mounted motor is locked and fixed by multiple screws. This type of mid-mounted motor needs to be equipped with a customize...
