Problems solved by technology

[0003] When the rider wants to brake, they usually hold the brake lever tightly to drive the brake calipers to brake the rear wheel. However, for some riders with insufficient grip strength, such as children or the elderly, the old brake design There may be no way to achieve the desired effect, which virtually increases the risk of riding, so the industry has developed a structure that uses the reverse pedal to produce a braking effect, such as US4,261,449 and US5,810,139 patents Application, that is to say, when the chain is stepped on and reversed by the crank, the brake mechanism arranged in the hub axle is linked to brake the rear wheel; but at present, such designs are only used in general bicycles and not actually used in bicycles. electric bicycle

Embodiment Construction

[0038] In order to describe the structure, features and functions of the present invention in detail, two preferred embodiments are listed and described in conjunction with the following figures.

[0039] see Figure 1 to Figure 3 , the reverse braking mechanism 10 provided by the first preferred embodiment of the present invention is mainly used in electric bicycles, and includes a motor 20, a crankshaft 30, a large chainring 40, a clutch 50, and a sensor 60 .

[0040] The motor 20 is installed on the frame of the electric bicycle to provide power assistance. Since the motor 20 is a common structure for those skilled in the art, it will not be described in detail here.

[0041] The crankshaft 30 passes through the motor 20 and is connected to a crank 32 at its two ends, which can be rotated forward or reversed relative to the motor 20 by an external force.

[0042] The large tooth plate 40 has a sleeve 42, the sleeve 42 is rotatably sleeved on the crankshaft 30 by a bearing...

Abstract

The invention relates to an anticlockwise-rotation braking mechanism of an electric bicycle. The inversion braking mechanism mainly comprises a motor, a crank shaft, a crankset and a clutch, wherein the crank shaft is arranged in the motor in a penetrating way and a rotatable manner; the crankset is provided with a sleeve connected with the motor and the crank shaft; the clutch is arranged between the crank shaft and the sleeve of the crankset; when the crank shaft clockwise rotates, the clutch drives the crankset to clockwise rotate under the driving of the crank shaft; when the crank shaft anticlockwise rotates, the clutch and the sleeve rotate relatively under the driving of the crank shaft, and a period of delay time is generated, so that the motor stops supplying assistant power; and then the clutch can drive the crankset to anticlockwise rotate within the delay time, so that a braking effect is achieved.

Description

technical field [0001] The invention relates to an electric bicycle, in particular to a reverse braking mechanism of the electric bicycle. Background technique [0002] Generally, when riding a bicycle, the rider presses the pedals with both feet and drives the crankshaft to rotate in a positive way. The rear wheel is driven to rotate through the chain to achieve the purpose of driving the bicycle forward. [0003] When the rider wants to brake, they usually hold the brake lever tightly to drive the brake calipers to brake the rear wheel. However, for some riders with insufficient grip strength, such as children or the elderly, the old brake design There may be no way to achieve the desired effect, which virtually increases the risk of riding, so the industry has developed a structure that uses the reverse pedal to produce a braking effect, such as US4,261,449 and US5,810,139 patents Application, that is to say, when the chain is stepped on and reversed by the crank, the b...
