Description

A bicycle with alarm function

technical field

The utility model relates to a bicycle, in particular to a bicycle with an alarm prompt function.

Background technique

Bicycles are commonly used means of transportation and fitness tools for people, but with the increase in the per capita possession of bicycles and electric vehicles, and the complex and changeable urban traffic environment, cycling, especially when turning bicycles, often results in congestion due to the number of cars. Accidents such as scratches and rear-end collisions are caused, which are a great hidden danger to the safety of cyclists, and also cause many economic losses.

If an intelligent alarm device can be added to the bicycle, it can automatically monitor whether there are vehicles approaching on both sides and the rear side of the bicycle, and automatically detect whether the bicycle is about to turn, and remind the cyclist and the approaching person in time, it can be very effective To alleviate the loss caused by bicycle collision and rear-end collision.

Contents of the invention

The purpose of the utility model is to provide a bicycle with an alarm prompt function that can give a reminder of vehicle approach and vehicle turning according to the surrounding vehicles and steering induction.

The bicycle with alarm prompting function of the utility model includes a bicycle body, and a prompting device is arranged under the seat cushion of the bicycle body, and the alarm prompting device includes a power supply, a controller, an ultrasonic module, an acceleration sensor module, a sounding module and a display lamp module, The controller is respectively connected with the power supply, the ultrasonic module, the acceleration sensor module, the sound module and the display light module.

In the above-mentioned technical scheme, described controller can be provided with switch button, and described controller can be Arduino uno single-chip microcomputer, and described ultrasonic module can adopt SR04 ultrasonic module, and described acceleration sensor module can adopt ADXL335 acceleration module, so The above-mentioned sound module usually uses a buzzer, and the above-mentioned display light module can use RGB three-color LED lights.

The utility model uses the ultrasonic module to measure the distance between the two sides of the bicycle, the tail and other objects, uses the acceleration module to collect the three-axis acceleration of the bicycle, and sends it to the controller. 1. Predict the steering of the bicycle, and control the flashing of LED lights of different colors according to the prediction results, that is, use the red LED light to notify the surrounding cyclists that there are bicycles in front or on the side, and use the left and right blue LED lights to notify the surrounding cyclists who are approaching The bicycle ahead turns. Simultaneously, if the red LED light is on, the controller starts the sounding module to give an alarm to the user and the surrounding riders who are close to the bicycle.

The utility model has the beneficial effects that: the bicycle with the alarm prompt function can detect the approach of surrounding vehicles and the steering direction of the bicycle, and give an alarm prompt to the user and the surrounding cyclists, which is beneficial to alleviate the accidents of bicycle collision and rear-end collision .

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described further.

Referring to Fig. 1 and Fig. 2, the bicycle with alarm prompting function of the present utility model includes a bicycle body, and a prompting device is provided under the seat cushion of the bicycle body, and the prompting device includes a power supply 1, a controller 2, an ultrasonic module 3, an acceleration sensor The module 4, the sound module 5 and the display lamp module 6 are connected.

In the above technical scheme, the controller 2 is provided with a switch button, the controller 2 can be an Arduino uno microcontroller, the ultrasonic module 3 can be an SR04 ultrasonic module, and the acceleration sensor module 4 can be an ADXL335 acceleration module, The sound module 5 can be a buzzer, and the display light module 6 can be an RGB three-color LED light.

The utility model adopts the ultrasonic module to collect the distance between the two sides of the bicycle, the tail and other objects, and sends it to the controller, and the controller predicts whether there are vehicles or obstacles around through the distance data. When the measured distance is less than 50cm after conversion, it is considered that there are vehicles approaching around the bicycle, and the controller outputs an analog signal to the red light in the display light module to make the red light emit maximum brightness, and outputs an analog signal to the sound module to make the sound The module emits sound to remind the user and surrounding cyclists. At the same time, the acceleration sensor module is used to collect the three-axis acceleration data when the bicycle is running, and send it to the controller. The controller predicts whether the bicycle will turn or not through the acceleration data. When the measured acceleration data has obvious non-periodic sudden changes, It is considered that the bicycle is about to turn, and the direction of the bicycle is judged according to the value of the acceleration data change, and at the same time, the controller outputs an analog signal to the left or right blue light in the corresponding display light module, so that the corresponding light The maximum brightness is emitted to remind the surrounding cyclists. When the user does not use the bicycle, press the controller switch to turn off the controller and other modules.
