Abstract
The utility model provides an electric vehicle safety sound generation alarm device which comprises a vehicle speed detector, a sound generator and a single chip microcomputer (SCM). The vehicle speed detector is used for detecting a motor speed in drive process of an electric vehicle, the sound generator is used for sending alarming information in a sound mode, and the SCM is used for receiving the motor speed detected through the vehicle speed detector and triggering the sound generator to send sound with different intensity according to the variation of the motor speed. The vehicle speed detector and the sound generator are both connected with the SCM. Due to the fact that the vehicle speed detector, the sound generator and the SCM are arranged for the electric vehicle safety sound generation alarm device, the device is capable of sending a certain continuous sound in real time according to the high and low variation of the speed of the electric vehicle. The higher the vehicle speed is, the larger the sound is; and the lower the vehicle speed is, the smaller the sound is. Therefore, the electric vehicle can be timely noticed by surrounding people and vehicles, and the driving safety of the electric vehicle is greatly improved.
Description
Technical field
The utility model belongs to electric automobiles, is specifically related to the safe sounding alarming device of a kind of battery-driven car.
Background technology
At present, people go on a journey and use the people that automobile or motor bike are ridden instead of walk to get more and more, and make the carbon dioxide content in atmosphere more and more.And live under this environment, be exactly the biggest threat to our health.Therefore, the development prospect of the electric motor car with two wheels of energy-conserving and environment-protective, can not be ignored, its feature is light and handy, convenient, economical and practical, and the more important thing is that it is not to adopt fuel engines to drive, there is no exhaust emissions, pollution-free to atmosphere, also saved the fuel cost that present price in the world rises steadily simultaneously.
But, because adopting DC motor, battery-driven car drives, and when motor moved, the sound that it sends was very small, and was flooded by environmental noise, and the battery-driven car of noiseless form is easily ignored by the people, has consisted of the unsafe factor of arteries of communication.
The utility model content
The utility model provides a kind of battery-driven car safe sounding alarming device for above-mentioned the deficiencies in the prior art, and the safe sounding alarming device of this battery-driven car can send the continuous sound according to the height speed of the speed of a motor vehicle, guarantees traffic safety.
The utility model is achieved by the following technical solution:
The safe sounding alarming device of a kind of battery-driven car is characterized in that, comprising:
One speed of vehicle detector is for detection of battery-driven car motor speed under steam;
One rattler is used for sending information warning in the mode of sound;
One micro controller system be used for to receive the motor speed that speed of vehicle detector detects, and according to the difference of described motor speed, triggers the sound that producer sends varying strength;
Described speed of vehicle detector all is connected with micro controller system with rattler.
Further setting of the present utility model is, the signal that described rattler sends is the low sound level of 60-80dB.
Further setting of the present utility model is, intensity and the motor speed of the sound that described rattler sends are proportional.
Further setting of the present utility model is, the sound the when sound that described rattler sends is worked with fuel engines is consistent.
The safe sounding alarming device of battery-driven car described in the utility model is by arranging speed of vehicle detector and rattler and micro controller system, make this device can be according to the height speed of the battery-driven car speed of a motor vehicle, send in real time certain continuous sound, the speed of a motor vehicle is faster, sound is larger, and the speed of a motor vehicle is lower, and sound is less, thereby can make surrounding population and vehicle in time notice battery-driven car, the travel safety of battery-driven car is promoted greatly.
Description of drawings
Fig. 1 is the structured flowchart of the safe sounding alarming device of battery-driven car described in the utility model.
The specific embodiment
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, the utility model provides a kind of battery-driven car safe sounding alarming device, comprises speed of vehicle detector, rattler and micro controller system, and described speed of vehicle detector all is connected with micro controller system with rattler.Speed of vehicle detector is for detection of battery-driven car motor speed under steam; Rattler is used for sending information warning in the mode of sound; Micro controller system be used for to receive the motor speed that speed of vehicle detector detects, and according to the difference of described motor speed, triggers the sound that producer sends varying strength.Preferably, the signal that described rattler sends is the low sound level of 60-80dB, prevents that it from bringing excessive noise.The intensity of the sound that described rattler sends can be proportional with motor speed, also can with the stepped proportional relation of motor speed.The sound when sound that described rattler sends can be worked with fuel engines is consistent, also can imitate other sound, thereby makes this safe sounding alarming device more be rich in personalized color.
The above is preferred embodiment of the present utility model, and all equivalent variations of doing according to the utility model claim all should belong to protection domain of the present utility model.
