Description

A kind of anti-Bicycle Tail Light that knocks into the back

Technical field

The utility model relates to a kind of bicycle accessories, is specifically a kind of anti-Bicycle Tail Light that knocks into the back.

Background technology

The taillight of current bicycle is made primarily of plastic reflector, and these taillights can not self-luminescence, relies on the reflection of periphery light, reminds front vehicle to note maintaining safe distance.But due to its passive reflective principle, when marginal ray is bad, good warning function can not be played, the traffic accident that easy generation vehicle and bicycle knock into the back.

In order to solve the problems of the technologies described above, Chinese patent 201020663738.3 discloses a kind of automatic bicycle tail lamp, comprise power module, acceleration sensor module, voltage comparator, amplifying circuit and LED lamp module, power module is connected with voltage comparator with acceleration sensor module respectively, acceleration sensor module is connected with voltage comparator, and acceleration sensor module is used for the magnitude of voltage bicycle brake brief acceleration detected being converted to output signal, the mouth of voltage comparator and amplifying circuit, LED lamp module connects successively, and when the magnitude of voltage of acceleration sensor module output signal is higher than reference voltage level, voltage comparator exports high level, then LED lamp module is lighted by amplifying circuit.This utility model structure is simple, easy to use, use the active luminescence of LED lamp module, and according to the automatic bright light of bicycle running situation, super low-power consumption, has good practicality and convenience.But there is following problem in it: 1. front vehicle could be reminded to maintain safe distance during brake, when bicycle does not brake, it can not play the effect of prompting; 2. it can only remind the vehicle at rear to maintain safe distance, and crosses people rear by bike closely can not be reminded to have car when spacing.

Utility model content

Problem to be solved in the utility model is to provide a kind of anti-Bicycle Tail Light that knocks into the back, under marginal ray dim environment by bike, when spacing is crossed near, it can remind front vehicle to note maintaining safe distance to cyclist, people by bike can be reminded to notice that there is car at rear simultaneously, reduce the possibility that accident occurs.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of anti-Bicycle Tail Light that knocks into the back, comprise shell, power module, single chip control module, ultrasonic distance-measuring sensor module, LED lamp module and buzzer phone is provided with in its housing, described power module is connected with ultrasonic distance-measuring sensor module with single chip control module respectively, and described single chip control module is connected with ultrasonic distance-measuring sensor module, LED lamp module and buzzer phone respectively.

Preferably, the above-mentioned anti-Bicycle Tail Light that knocks into the back, wherein said power module, single chip control module, ultrasonic distance-measuring sensor module, LED lamp module and buzzer phone all assign on same pcb board, and described pcb board is arranged in described shell.

Preferably, the above-mentioned anti-Bicycle Tail Light that knocks into the back, wherein said power module is LM2940 chip.

Preferably, the above-mentioned anti-Bicycle Tail Light that knocks into the back, wherein said single chip control module is 89C51 chip.

Preferably, the above-mentioned anti-Bicycle Tail Light that knocks into the back, wherein said ultrasonic distance-measuring sensor module is TL852 chip.

Preferably, the above-mentioned anti-Bicycle Tail Light that knocks into the back, the LED of wherein said LED lamp module to be multiple rated current be 10mA.

Preferably, the above-mentioned anti-Bicycle Tail Light that knocks into the back, wherein said buzzer phone adopts active buzzer.

Technique effect of the present utility model is mainly reflected in: the range information between the bicycle tail recorded and front vehicle is passed to single chip control module by ultrasonic distance-measuring sensor module, the distance value of the distance value recorded and setting can compare by single chip control module, when the distance value recorded is less than the distance value of setting, single chip control module send signal light LED lamp module, control buzzer phone send the sound, front vehicle is reminded to note maintaining safe distance, attention people rear by bike can be reminded to have car simultaneously, reduce the possibility that accident occurs.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 longitudinal sectional view of the present utility model;

Fig. 3 functional block diagram of the present utility model.

As shown in the figure: 1-shell, 2-PCB plate, 3-power module, 4-single chip control module, 5-distance measuring sensor module, 6-LED lamp module, 7-buzzer phone, 11-mount pad, 21-spiral nail.

Detailed description of the invention

Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is further told about, be easier to make the technical solution of the utility model understand and grasp.

As Fig. 1 to 3 shows, a kind of anti-Bicycle Tail Light that knocks into the back, comprise transparent shell 1, shell 1 is fixedly installed one for being arranged on the mount pad 11 on bicycle, one piece of pcb board 2 is fixed with four spiral nails 21 in shell 1, pcb board 2 has been assigned respectively power module 3, single chip control module 4, ultrasonic distance-measuring sensor module 5, LED lamp module 6 and buzzer phone 7, power module 3 selects LM2940 chip

Single chip control module 4 selects 89C51 chip, and ultrasonic distance-measuring sensor module 5 selects TL852 chip,

LED lamp module 6 is five rated current is the LED of 10mA, buzzer phone 7 adopts active buzzer, power module 3 is connected with single chip control module 4, ultrasonic distance-measuring sensor module 5 respectively, and single chip control module 4 is connected with ultrasonic distance-measuring sensor module 5, LED lamp module 6 and buzzer phone 7 respectively.

By bike in process, range information between the bicycle tail recorded and front vehicle is passed to single chip control module 4 by ultrasonic distance-measuring sensor module 5, the distance value of the distance value recorded and setting can compare by single chip control module 4, when the distance value recorded is less than the distance value of setting, single chip control module 4 send signal light LED lamp module 6, control buzzer phone 7 send the sound, LED lamp module 6 luminescence can remind front vehicle to note maintaining safe distance, the sound can remind people by bike to notice that there is car at rear, reduces the possibility that accident occurs.

Certainly; these are only preferred embodiment of the present utility model; non-ly therefore namely limit to the scope of the claims of the present utility model, all utilization the utility model specification sheetss and graphic content institute be simple and easy modification and equivalent structure change for it, all should in like manner be contained within scope of patent protection of the present utility model.
