技术领域 technical field

Specifically, it is a bicycle that uses electromagnetic action to brake and is equipped with a Beidou navigation device, a weather forecast device, a loudspeaker device and a wind speed measurement device.
背景技术 Background technique
目前全世界都面临着环保与节能的严峻形势。世界上许多大城市的空气都已严重污染,汽车排出的尾气是最大的污染源之一。据统计,城市交通中盛行的私家汽车、摩托车排放的CO2占到全世界CO2排放总量的1/4以上,而不少城市车辆造成的高于70分贝噪音也远远超过人类听觉可接受的合适音量。另外,我国目前私家车每年消耗石油总量超过1.15亿吨,能源危机迫在眉睫。自行车由于无噪音、无污染、节约能源、节省道路空间等特点,被人们称为绿色交通工具,已受到广泛关注,必将在21世纪成为最好的人类轻型代步工具。At present, the whole world is facing the severe situation of environmental protection and energy saving. The air in many big cities in the world has been seriously polluted, and the exhaust gas from automobiles is one of the biggest sources of pollution. According to statistics, the CO 2 emitted by private cars and motorcycles prevalent in urban traffic accounts for more than 1/4 of the world's total CO 2 emissions, and the noise caused by many urban vehicles is higher than 70 decibels, far exceeding the human hearing Acceptable moderate volume. In addition, my country's current private cars consume more than 115 million tons of oil per year, and the energy crisis is imminent. Due to the characteristics of no noise, no pollution, energy saving, and road space saving, bicycles are known as green vehicles and have received widespread attention. They will surely become the best light-duty means of transportation for human beings in the 21st century.
几年前开始拥有成熟制作工艺的电动自行车证明依靠自行车领域的发展在一定程度上替代燃油汽车的思路是可行的。自2008年开始我国电动车市场上又出现了一种能带自充电功能的电动自行车,这种车型可以将电动车平地滑行、下坡滑行和骑行时产生的能量再生利用,使机械能自动转换成电能储存进蓄电池中,降低了成本。现在市面上广泛使用的都是这种车型,但这种车型有两点不足之处,一方面,这种车型有一个普遍的问题,即用户骑行时把一部分力量通过电机转化电能存入电瓶,电瓶的中的电力再驱动电机带动车子前进,但用户骑行的时候比较费力,因此说这种设计思路有很大的局限性。另一方面,电动自行车本身虽然环保,但是电动自行车的电池续航时间普遍很短,对于需要较长途出行的用户而言往往是前半段靠电动、后半段靠脚蹬,由于电动车电池重量大使得脚蹬时很吃力。这些劣势决定了电动车至今无法广泛取缔自行车的现状。A few years ago, electric bicycles with mature production technology proved that it is feasible to rely on the development of the bicycle field to replace fuel vehicles to a certain extent. Since 2008, an electric bicycle with self-charging function has appeared in my country's electric vehicle market. This model can regenerate the energy generated by the electric vehicle when sliding on the flat ground, sliding downhill and riding, so that the mechanical energy can be automatically converted. The electrical energy is stored in the storage battery, which reduces the cost. This type of model is widely used in the market now, but it has two shortcomings. On the one hand, this type of model has a common problem, that is, when the user is riding, a part of the power is converted into electric energy by the motor and stored in the battery. , The electric power in the battery then drives the motor to drive the car forward, but it is more laborious for the user to ride, so this design idea has great limitations. On the other hand, although the electric bicycle itself is environmentally friendly, the battery life of electric bicycles is generally very short. For users who need to travel for a long distance, they often rely on electric power for the first half and pedaling for the second half. Due to the heavy weight of electric bicycle batteries It is very difficult to pedal. These disadvantages have determined that electric vehicles cannot widely ban bicycles so far.
现在市场上流行的自行车前后刹车设计多以钢线拉动胀蹄式制动,限制条件强,比如刹车的闸皮和固定轮之间的角度应控制在水平30度左右,刹车鼓上面的微调螺丝需要定期更换等等。随着使用时间的延长,闸皮、闸线逐渐老化,灵敏度会降低。The front and rear brakes of bicycles that are popular in the market now mostly use steel wires to pull the expansion shoe brake, which has strong restrictions. For example, the angle between the brake pad and the fixed wheel should be controlled at about 30 degrees horizontally, and the fine-tuning screw on the brake drum Need to be replaced periodically etc. With the prolongation of use time, the brake skin and the brake line will gradually age, and the sensitivity will decrease.
现在大中型城市中交通路况愈加复杂,用户到郊外游玩时也容易迷路,因此在自行车上安装一个电子导航装置是有必要的。自2000年GPS系统开始在中国机动车领域流行以来,很多生产商也把GPS应用到摩托车、电动自行车上来。但是GPS系统由美国国防部研制和维护,我国用户的使用权限必将受制于人。除此之外,当用户在小区、街道等区域行驶时,经常遇到大货车、大客车等大型车辆掉头的情况。司机由于车体庞大无法看到车后部的景象,骑自行车的人来不及躲闪,冲司机喊叫又往往听不见,导致自行车被大车撞倒碾压。为了安全起见,在自行车上安装一个扬声器也是有必要的。Now the traffic road conditions in large and medium-sized cities are more and more complicated, and users are also easy to get lost when they go to the outskirts to play. Therefore, it is necessary to install an electronic navigation device on the bicycle. Since the GPS system became popular in China's motor vehicle field in 2000, many manufacturers have also applied GPS to motorcycles and electric bicycles. However, the GPS system is developed and maintained by the U.S. Department of Defense, and the use authority of users in our country will be restricted by others. In addition, when users are driving in residential areas, streets and other areas, they often encounter situations where large vehicles such as trucks and buses make U-turns. The driver couldn't see the rear of the car due to the size of the car, and the cyclist had no time to dodge, and often couldn't hear the driver shouting, causing the bicycle to be knocked down and crushed by the big car. It is also necessary to have a speaker on the bike for safety reasons.
