Abstract
The utility model relates to a brake structure of an electric bicycle, in particular to a sideslip prevention braking auxiliary device of the electric bicycle. The sideslip prevention braking auxiliary device of the electric bicycle comprises a braking motor and a cam, wherein the braking motor is installed on a connecting beam between a rear wheel and a bicycle body, the cam is connected with a braking motor shaft, a brake cable is wound on the periphery of the cam, one end of the brake cable is connected with a brake disc on the rear wheel, and the other end of the brake cable is connected with a brake handle. According to the sideslip prevention braking auxiliary device of the electric bicycle, the degree of tightness of the brake cable is changed through a cam structure, the brake disc on the rear wheel is in a high-speed circulating process of tight brake and loosening, thus the sideslip condition or the drift condition or even the rollover condition caused by emergency braking of the electric bicycle is avoided, the stable effect in emergency braking of the electric bicycle is improved, braking performance of the electric bicycle is improved, and the accident rate of the electric bicycle is effectively reduced.
Description
Technical field
The utility model relates to a kind of Electrical Bicycle brake gear, especially relates to the anti-brake auxiliary device that breaks away of Electrical Bicycle.
Background technology
Electrical Bicycle is meant with storage battery on the basis of ordinary bicycle, has installed control members such as motor, controller, storage battery, handle brake lever as auxiliary energy, realizes that manpower is foot-operatedly ridden, the extraordinary bicycle of electronic or electric power-assist function.During electronic use, by motor with storage battery electric energy conversioning mechanical energy, the drive wheels rotation.Electrical Bicycle is used by people as the Personal Transporter is more and more owing to easy to use, laborsaving.
Electrical Bicycle is by handle the signal of controller to be passed to motor when electronic travelling, and makes the electric vehicle motor rotation.Existing brake structure is generally formed by brake disc and the brake cable that links to each other with brake lever are installed on trailing wheel, and brake disc directly links to each other with brake cable, and when Electrical Bicycle braked, the brake lever internal electronics was exported to an electric signal of controller; After controller receives this signal, will cut off power supply to motor, by the brake cable that links to each other with brake lever, the control brake disc, thus realize the brake power down function.
This moment Electrical Bicycle because directly braking, when wet and slippery area and emergency braking, sideslip is taken place and causes Electrical Bicycle generation overturning, dangerous hidden danger in trailing wheel easily.
Summary of the invention
For solving the problems of the technologies described above, technical problem to be solved in the utility model is the phenomenon of incident overturning when overcoming the brake of above-mentioned prior art Electrical Bicycle, sideslip, and provide a kind of Electrical Bicycle the anti-brake auxiliary device that breaks away, this device can increase the stability of Electrical Bicycle when emergency braking, improves the Electrical Bicycle deceleration and stopping performance.
For solving the problems of the technologies described above, technical solutions of the utility model are achieved in that the anti-brake auxiliary device that breaks away of Electrical Bicycle, comprise a braking motor and a cam, it is characterized in that: described braking motor is installed on the tie-beam between trailing wheel and the car body, described cam links to each other with the braking motor axle, the periphery of described cam is wound with brake cable, and an end of described brake cable links to each other with the brake disc on the trailing wheel, and the other end of described brake cable links to each other with brake lever.
Described braking motor links to each other with the storage battery of Electrical Bicycle.
The utility model beneficial effect, the utility model passes through cam structure, the brake cable degree of tightness is changed, make brake disc on the trailing wheel like this in stop tight and the high speed cyclic process of decontroling, just put and stop, thereby avoided Electrical Bicycle because of the anxious sideslip or the drift situation of stopping and causing, even caused overturning
The utility model is simple in structure, is convenient to implement, and has increased the stablizing effect of Electrical Bicycle when emergency braking again, improves the Electrical Bicycle deceleration and stopping performance, and effectively reduces the accident rate of Electrical Bicycle.
Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of specification sheets, and for above-mentioned purpose of the present utility model, feature and advantage can be become apparent, below especially exemplified by preferred embodiment, illustrated.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
For further setting forth the utility model is to reach technological means and the effect that predetermined goal of the invention is taked, below in conjunction with accompanying drawing and preferred embodiment, to the specific embodiment, structure, feature and effect thereof according to the anti-brake auxiliary device that breaks away of the Electrical Bicycle that the utility model proposes, describe in detail as after.
As shown in Figure 1, the anti-brake auxiliary device that breaks away of the utility model Electrical Bicycle comprises a braking motor 1 and a cam 2.
Described braking motor 1 is installed on the tie-beam 5 between trailing wheel 3 and the car body 4, just the position of back mounting below.Described cam 2 links to each other with 1 of braking motor, when braking motor 1 rotates, and cam 2 beginning rotation works, promptly braking motor 1 drives cam 2 and makes high-speed operation.Described braking motor 1 links to each other with the storage battery of Electrical Bicycle, and promptly the storage battery of Electrical Bicycle provides power resources to braking motor 1.
Periphery at cam 2 is wound with brake cable 6, and an end of described brake cable 6 links to each other with brake disc 7 on the trailing wheel, and the other end of described brake cable 6 links to each other with brake lever 8.
When the utility model uses, when the people that rides needs brake, the switch opens of storage battery and braking motor 1, drive cam 2 rotations, thereby brake cable 6 degrees of tightness are changed, reach and the rear wheel brake dish is in stop in tight and the high speed cyclic process of decontroling, promptly stop, thereby avoided Electrical Bicycle because of the anxious sideslip of causing or the situation of drifting about of stopping.To improve the safety performance that Electrical Bicycle is ridden, make Electrical Bicycle energy-conservation, advantage is more added in environmental protection on the basis of low-carbon (LC).
The description of above-mentioned embodiment is the utility model preferred embodiment, but can not limit protection domain of the present utility model with this, and variation and the modification of being done in this way in every case is all within protection domain of the present utility model.
Claims (2)
1. Electrical Bicycle is prevented the auxiliary device that brakes that breaks away, comprise a braking motor and a cam, it is characterized in that: described braking motor is installed on the tie-beam between trailing wheel and the car body, described cam links to each other with the braking motor axle, the periphery of described cam is wound with brake cable, one end of described brake cable links to each other with the brake disc on the trailing wheel, and the other end of described brake cable links to each other with brake lever.
2. the anti-brake auxiliary device that breaks away of Electrical Bicycle according to claim 1, it is characterized in that: described braking motor links to each other with the storage battery of Electrical Bicycle.
