Abstract

The utility model relates to an automatic alarm for a bicycle, comprising a box body, a lock, a hoop and a ring, wherein the lock is installed at the side of the box body; the hoop is arranged at the bottom of the box body; an alarm system comprising an inductive circuit, a vibrating sensor, a microswitch, a buzzer and a battery is arranged in the box body; the alarm system can be switched on by locking the lock; when the lock is locked, the box body and a top cover are locked, meanwhile, the alarm system is started so that the automatic alarm is in an early alarm state; and when the bicycle is vibrated due to being stolen, the automatic alarm sounds and alarms. The automatic alarm adopts the principle of combining a machine and electricity, has novel, firm and reliable structure and effectively frightens stealers to avoid the phenomenon of stealing the bicycle; meanwhile, the battery of the automatic alarm is installed in the firm box body without an external power supply, thereby avoiding cutting off a power line to cause the automatic alarm to fail.

Description

The bicycle autoalarm

Technical field

The utility model relates to a kind of bicycle theft-prevention device, particularly bicycle autoalarm, is to the innovation of bicycle annunciator in the past.

Background technology

Bicycle can be ridden instead of walk because of its environmental protection, energy-conservation, furthermore economical and practical in traffic, can have sports again, thereby be subjected to the numerous common people's welcome.At present, under the serious situation of energy scarcity and environmental pollution, use the people of bicycle more and more, but when using bicycle, also bring worries to the user, the anti-theft capability that is exactly bicycle is poor, and the stolen phenomenon of bicycle is serious.Stolen for preventing bicycle, people once found out many ways, what it used morely is anti-theft column lock, the lock headstock is arranged, and the lock wheel is arranged, and had headstock, wheel to lock simultaneously, and were numerous.This class anti-theft measure, though certain antitheft effect is arranged, the structural defect of its mechanicalness anti-theft column lock is cut off or is destroyed easily, still fails to prevent effectively the generation of bicycle theft phenomenon, people are still in the antitheft problem of constantly exploring bicycle.

Summary of the invention

The utility model provides a kind of bicycle autoalarm, and the antitheft mode that it adopts mechanical lock to combine with warning circuit threatens stealer effectively, thereby reaches the purpose that prevents that bicycle from being stolen.

Technical solution adopted in the utility model:

A kind of bicycle autoalarm, comprise casing, loam cake, tapered end, lock ring, jingle bell, wherein tapered end is installed in the side of casing, iron hoop is installed in the bottom of casing, it is characterized in that in casing, being provided with sensor circuit, Shock inductor, micro-switch, buzzer phone, battery, Shock inductor places the casing medium position, and sensor circuit and buzzer phone all place the casing low inside to put, battery place with the corresponding casing of tapered end in a side; Battery is connected with micro-switch by transmission line, and micro-switch is connected with Shock inductor and sensor circuit by transmission line, and the mouth of sensor circuit connects buzzer phone.

Described jingle bell top is provided with button switch, and the jingle bell bottom is provided with check screw, is convenient to be installed on the handlebar handle, and the button switch of jingle bell is connected with battery in the casing by transmission line.

Described bottom half is provided with the flats sound penetrating hole, and during warning, the alert sound that sends from buzzer phone spreads out of warning by sound penetrating hole.

This structure bottom half one side is provided with iron hoop and colludes, and opposite side is provided with screw, and iron hoop colludes with screw by iron casing is fixed on the handlebar; Be provided with the lock hook ear in the bottom surface of casing top cover, the tapered end end is provided with lock hook, and when sealed, lock hook is buckled on the lock hook ear and top cover and casing is sealed in aggregates.

This structure casing side also is provided with link, the annunciator casing is installed in easily positions such as door, window or padlock by link.

The operating process of this annunciator: the annunciator casing is installed on the handlebar handle, inserts tapered end, when locking, start warning, make annunciator be in alert status with key; The rear box lid of locking can't be opened, and stealer can't destroy the warning in the casing.System is given a shock if warning is opened the back, will send early warning signal, then long time of alarm; After the alarm release, annunciator returns alert status automatically.

Characteristics of the present utility model: this annunciator is compared with traditional anti-theft lock for bicycle, adopts physical construction and the electric alarm principle that combines, and novel structure, strong, safe, reliable can threaten stealer, prevents that effectively the stolen phenomenon of bicycle from taking place; The battery of this annunciator places in the crash-resistant casing, does not need externally fed, can prevent to cut off electric transmission line and annunciator was lost efficacy; This structure also is provided with jingle bell simultaneously, uses when being convenient to bicycle running.

The specific embodiment

The contrast accompanying drawing describes in detail.

In Fig. 1～3, this annunciator comprises casing, loam cake, tapered end, iron hoop, jingle bell, and tapered end 2 is installed in the side of casing 1, and iron hoop 16 is installed in the bottom position of casing, and casing is fixed on the handlebar of bicycle head by iron hoop.Shock inductor 5 places the casing medium position, and sensor circuit 6 and buzzer phone 8 place lower box, battery 4 place with the corresponding casing of tapered end in a side; Battery is connected with micro-switch 7 by transmission line, and micro-switch is connected with Shock inductor 5 and sensor circuit 6 by transmission line, and the mouth of sensor circuit connects buzzer phone 8, and above-mentioned electronic component is placed in the interior plastic casing 12 of casing.

Jingle bell 20 is installed in the handlebar handle other end by the screw of bottom, and the button switch 18 of jingle bell is connected with battery 4 in the annunciator casing by transmission line.

Screw 15 and the iron hoop of this annunciator by bottom half colludes 17 and from box house iron hoop 16 is fixed on the handlebar handle, loam cake 9 again closes, lock by tapered end with key, the lock hook 3 of tapered end end fastens the lock hook ear 11 of loam cake the inside at this moment, loam cake and casing constitute crash-resistant integral body, if do not use key, external force is difficult to open from the outside top cover.After locking, the warning in the casing is in alert status, if there are vibrations to take place, by Shock inductor, the triggering micro-switch is connected warning and then started annunciator and spreads out of warning by sound penetrating hole 14.

In Fig. 4, micro-switch 7 is connected with battery 4 and Shock inductor 5 by transmission line, and when vibrations took place, micro-switch was connected battery and sensor circuit 6, thereby drives buzzer phone 8 sounding alarms; After the elimination of reporting to the police, this annunciator is replied alert status.Because micro-switch is the bikini switch, both as the switch of warning, as the switch of common jingle bell, when pressing the button 18 of jingle bell, the battery by in the micro-switch connection casing supplied jingle bell 20 (loudspeaker) sounding power again.In Fig. 5, an iron link 19 is installed on this annunciator casing, annunciator can be installed to Anywhere, for example places such as door, window, padlock place are very convenient.
