The acceleration sensor detection module is used for detecting whether a device is horizontal, so that the accuracy is high, the traffic safety is facilitated. The bicycle brake tail lamp has the advantages of simple structure, small volume, convenience for installation, and good applicability, and the sensitivity of the tail lamp can be regulated according to different road condition demands.
Description
Technical field
The utility model relates to a kind of bicycle accessories, particularly a kind of brake taillight.
Background technology
Bicycle is a kind of vehicle commonly used, because the characteristics such as its low-carbon (LC), environmental protection, health, be subject to liking of people, at present, most bicycle all is that taillight is not installed, the middle emergency brake if travel, front vehicle is not received brake alarming, when in time not making brake, is easy to lead to safety misadventure, especially carry out bicycle race or many people when riding, because speed is fast, number is many, may cause chain accident, causes larger injury, so, the bicycle brake tail-light safety measure that is very important.
Early stage bicycle brake device mostly is contact, install complicated, be not used widely, in recent years, some occur and used the Wireless stop lamp of acceleration pick-up, take Gravity accelerometer as the core detection means, judged whether the brake deceleration action according to the horizontal acceleration changing value, thereby light brake warning lamp, because the existence of vertical direction acceleration due to gravity, if the placement of detection means does not become level with ground, will affect the accuracy that horizontal acceleration detects, so Wireless stop lamp need to be installed on the horizontal surface parallel to the ground, present Wireless stop lamp mainly determines whether by human eye and is up to the standard, so that Wireless stop lamp detects brake very large error is arranged, be difficult to guarantee the accuracy of its level, cause like this brake to detect inaccuracy, cause Warning light wrong report or do not report, be unfavorable for traffic safety, in addition, present stoplight stop lamp sensitivity is that unification is set when producing, and the customer can not regulate according to different road conditions needs, causes its applicability to reduce.
The utility model content
Judge the installation level in order to overcome the main of prior art by human eye, be difficult to guarantee the deficiency of accuracy, the utility model provides a kind of level that the high bicycle brake tail-light of accuracy rate is installed.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of bicycle brake tail-light, comprise the power supply for power supply, also comprise the acceleration pick-up detection module that detects acceleration/accel on vertical and the horizontal direction, the MCU control module of analysis and processing signals, and brake alarming module and level demonstration feedback module, the input end of MCU control module connects the acceleration pick-up detection module, and the mouth of MCU control module connects the brake alarming module and level shows feedback module.
As improvement of the technical scheme, described acceleration pick-up detection module connects the MCU control module by IIC or SPI communication interface.
In order to make device sensitivity adjustable, increase its applicability, described acceleration pick-up detection module is installed in the housing that horizontal shaft rotates.
In order to reduce volume, improve portability, described power supply is alkaline battery, lithium cell or Ni-MH battery.
As further improvement in the technical proposal, described level shows that feedback module is that level shows the LED lamp.
In order to reach good alarming effect, described brake alarming module is stoplight stop lamp.
The beneficial effects of the utility model are: by acceleration pick-up detection module detecting device level whether, accuracy is high, is conducive to traffic safety, simple in structure, volume is little, is convenient to install, the sensitivity of device can be regulated according to different road conditions needs, and applicability is good.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is schematic block circuit diagram of the present utility model;
Fig. 2 is mounting structure scheme drawing of the present utility model.
The specific embodiment
See figures.1.and.2, a kind of bicycle brake tail-light of the present utility model, comprise the power supply for power supply, also comprise the acceleration pick-up detection module that detects acceleration/accel on vertical and the horizontal direction, the MCU control module of analysis and processing signals, and brake alarming module and level demonstration feedback module, the input end of MCU control module connects the acceleration pick-up detection module, and the mouth of MCU control module connects the brake alarming module and level shows feedback module.
As improvement of the technical scheme, described acceleration pick-up detection module connects the MCU control module by IIC or SPI communication interface, the MCU control module has judged whether brake or no putting is level attitude, and judged result is outputed to horizontal display module/brake alarming module.
Described acceleration pick-up detection module is take Gravity accelerometer as the core detection means, the result who utilizes weight sensor to detect judges whether Wireless stop lamp is installed on the horizontal surface, when level is put in brake, utilize level to show that positioner marks, remove from by human eye and judging, improved accuracy rate.
In order to make device sensitivity adjustable, increase its applicability, described acceleration pick-up detection module is installed in the housing 1 that horizontal shaft rotates, housing 1 upwards turned an angle from horizontal position can improve device sensitivity, rotate the sensitivity that certain angle can reduce equipment.
In order to reduce volume, improve portability, described power supply is movable power source, can be alkaline battery, lithium cell or Ni-MH battery, provides respectively electric power to acceleration pick-up detection module, MCU control module, horizontal display module/brake alarming module.
As further improvement in the technical proposal, described level shows that feedback module is that level shows LED lamp 2.
In order to reach good alarming effect, described brake alarming module is stoplight stop lamp 3.
In this specific embodiment, because that stoplight stop lamp 3 uses is comparatively frequent, act on also relatively more importantly, so stoplight stop lamp 3 is arranged to larger red colored lamp, level demonstration LED lamp 2 is set to less green LED lamp, thereby is convenient to both are made a distinction.
Certainly, the utility model can also have other structural distortion except above-mentioned embodiment, and these equivalent technical solutions also should be within its protection domain.
