Abstract
The utility model discloses an alarm for automobile hand brake which can remind a driver to lock the brake of a car when the car is stopped and stalled to avoid an accident. The utility model comprises an electronic switch circuit and a sounder, wherein, the electronic switch circuit is connected respectively with the positive and negative electrodes of the battery of the car via the ignition switch K-[1] of the car and a switch K-[2] which is arranged between the draw rod of the hand brake of the car and the supporting structure thereof. The utility model has the advantages that the structure is simple; the alarm is reliable because the switch K-[2] is controlled bythe hand brake directly; accidents caused by the malfunction of the pedal brake of the car can be avoided with the aid of the utility model when the car is stalled or sliding in neutral position.
Description
The utility model relates to a kind of car safety annunciator, and is particularly a kind of after parking of automobile is flame-out, the annunciator when hand brake also is not locked.
Chaufeur does not draw drg, the traffic accident that tends to lead to obstructed degree behind switch-off.During particularly with the acclive position of parking of automobile, just leave operator's compartment if forget the handle drg, will because of automobile from line slip, and cause the accident of car crash.Prior art yet there are no the warning device of reminding chaufeur to draw hand brake.
The purpose of this utility model is to provide a kind of warning device device of reminding chaufeur to draw hand brake, to stop the generation of above-mentioned traffic accident.
The utility model is to constitute like this, and promptly it is by electronic switch circuit, and rattler and housing constitute, and it is characterized in that the ignition lock K of the positive pole of electronic switch circuit input end by automobile
1Be connected with the positive pole of automobile storage battery, negative pole is by being installed in the gang switch K between automobile hand brake pull bar and its fixed mount
2Connect with the automobile storage battery negative pole; The mouth of electronic switch circuit is connected with rattler SP.
Said structure of the present utility model can further specify by accompanying drawing and the embodiment that provides thereof.
Accompanying drawing 1 is the scheme circuit of the utility model scheme one;
Accompanying drawing 2 is the scheme circuit of the utility model scheme two.
Referring to Fig. 1, electronic switch circuit is by aerotron BG

4An end connect R
4The other end passes through K
2Connect the storage battery negative pole.BG
1Emitter and BG
2Collecting electrode pass through resistance R respectively
3And R
2With the automobile storage battery positive pole be ignition lock K
1The positive voltage input end connect.After connecting with resistance W, capacitor C is connected on BG as the time-delay charhing unit
2Base stage and K switch
2The negative voltage mouth between, it is BG that rattler SP is connected on the electronic switch circuit mouth
1Collecting electrode and K
2Between the negative voltage input end.K
2For being installed in hand brake lever is switch on pull bar and its permanent seat, links with hand brake.K
2When being in the braking and locking state, hand brake is unlatching (disconnection) state, K when hand brake is in released state
2Be closed (connection) state.
The principle of work of circuit is such:
1. parking of automobile is flame-out, when hand brake is in locking state, and ignition lock K
1Disconnect K
2Disconnect with the negative voltage of storage battery output, whole electronic switch circuit is in off state, and rattler SP is sounding not.
2. parking of automobile is flame-out, and is hand braking when not being in locking state, K
1Disconnect, and K switch
2Connect with the negative voltage of storage battery input, at this moment time delay circuit (C, W, BG
2, R
4) enter discharge process; Positive charge passes through BG
2R flows through
4, W and finish discharge loop; Can determine by adjusting W discharge time.When the voltage on the C is put silicon triode BG when being lower than 0.6V
2Promptly end, and then make the D point voltage reduce to-0.6 volt, so BG
1Conducting, rattler SP obtains trigger voltage and sounds the alarm, and reminds chaufeur in time to lock hand brake, to avoid traffic accident.BG
1After the conducting, have only grip actuators locking to put in place after, reporting to the police just can stop.
The setting of time-delay is to leave the regular hour in order to finish other operations necessary process for chaufeur behind switch-off, reports to the police at once and causes that chaufeur is nervous and influence the normal running program to avoid occurring switch-off.Also be not lock hand brake simultaneously for chaufeur leaves operator's compartment in good time.
In addition, automobile when the coasting with engine off of acclive road surface, K
1, K
2Also belong to above-mentioned situation, warning acoustic energy is reminded the timely start the engine of chaufeur, to prevent causing the Floor Pump insufficient pressure to make the malfunctioning traffic accident that produces of service brake because of long-time flame-out neutral slides.
3. automobile is opened driving engine, i.e. K again
1Be in conducting, hand brake locking is K
2During disconnection, the electronic switch circuit negative voltage disconnects, and rattler can not sounding.
4. the automotive engine unlatching is K
1It is K that closure, hand brake are unclamped
2Closure is because positive voltage passes through R
1Make BG
2Positively biased and conducting, so the voltage that D is ordered is positive voltage, makes BG
1End, rattler SP can not report to the police.
Referring to Fig. 2, in this embodiment, electronic switch circuit is time base circuit IC and the peripheral cell diode D thereof of NE555 by model

2Can save.
The principle of work of above-mentioned circuit is such:
(1). work as K
1, K
2When all closed, promptly drive when vehicle is capable, when not pulling the hand brake, (2), (6) end that positive voltage is added in IC make it be high level, IC(3) output zero level, the SP no current by thereby sounding not, this moment, the capacitor C charging was power line voltage.
(2). when stopping, K
1Disconnect, automotive engine quits work, hand brake, and when not locking, K
2Still be in closure state IC, (2) disconnect with positive supply, and the electric charge on the C begins the discharge by W, and can adjust this discharge time by W.As IC(2) on voltage reduce to Battery voltage 2/3rds the time, IC(3) end saltus step be high level, SP gets electric and sounding.After chaufeur obtains alerting signal, make hand brake locking, i.e. K
2Disconnect, whole line broken circuit, chimes of doom stops.When automobile reruns, IC(2), (6) end almost is in high level simultaneously, K no matter at this moment
2Disconnect with closed, can not produce chimes of doom.
By above-mentioned explanation, be not difficult to find out that characteristics of the present utility model are circuit letters Single, dependable performance. Directly adopt automobile storage battery to make power supply, handle K with hand brake control2Break-make, alarm circuit is directly connected with the manipulation of hand brake, also can avoid the accident because the automobile flameout neutral position sliding is made or service brake is malfunctioning.
The utility model also can be used for the warning of the parking brake misoperation of tractor etc. except being used for auto alarm.
