Abstract
The utility model relates to an anti-theft and anti-robbing braking device for automobiles. The utility model is characterized in that the utility model is composed of a cipher circuit and an electromagnetic directional control valve. A coding circuit N2 in the cipher circuit can be made into a pluggable unit. A driver carries about the utility model or the coding circuit of an anti-theft and anti-robbing alarm device for the automobiles is directly adopted. A demoding circuit N1 can be installed in the electromagnetic directional control valve (3). The electromagnetic directional control valve (3) can be connected to the access point of a wheel braking device (1) or the electromagnetic directional control valve (3) is installed at the exit point of an automobile braking base pump (5) or the electromagnetic directional control valve (3) is connected between high-pressure oil tubes (2) and (4) between the wheel braking device (1) and the automobile braking base pump (5). The utility model can effectively prevent the automobile from theft and robbing.
Description
A kind of automobile burglar, the anti-brake equipment of robbing belongs to the automobile burglar technical field.
Along with the develop rapidly of science and technology and the variation of public security situation, automobile situation stolen, that be robbed happens occasionally, the serious harm social security and the people's life security, therefore, automobile anti-theft lock, antitheft, anti-misfortune annunciator progressively is used, and brought into play better action, present automobile burglar, the anti-annunciator of robbing, it is antitheft, anti-rob function all focus on control a bit at last, promptly cut off or connect the automobile ignition coil power supply.Its deficiency just is, for the general slightly cartheft of automobile circuit knowledge, under the situation of having destroyed annunciator, is easy in the short period of time, with a lead high-tension coil is directly linked to each other with storage battery, and automobile is stolen.
The purpose of this utility model just is to overcome the deficiencies in the prior art, and a kind of automobile burglar, the anti-brake equipment of robbing are provided, and when annunciator is malfunctioning, can prevents effectively that still automobile is stolen or is robbed.
The purpose of this utility model realizes in the following way:
This automobile burglar, the anti-brake equipment of robbing is characterized in that: form the encode circuit N in the cryptochannel by cryptochannel and the electromagnetism directional control valve with non-return valve function
2Can make plug-in unit, automobile burglar, anti-encode circuit of robbing in the annunciator, decoding circuit N are carried or directly adopted to chaufeur
1Can be installed in the electromagnetism directional control valve 3, electromagnetism directional control valve 3 can be connected car side brake 1 entrance be installed in automobile brake master cylinder 5 exits or be connected car side brake 1 and automobile brake master cylinder 5 between between the high pressure fuel pipe 2,4.
The purpose of this utility model can also realize in the following way:
Described cryptochannel can adopt VD5026, VD5027, VD5028, YYH26, YYH27, YYH28, HT12E, HT12F, HT12D, MC145026, MC145027, MC145028, MC145030 etc. to have the circuit or the decision circuit of coding and decoding function.
Described electromagnetism directional control valve 3 with non-return valve function can adopt one or morely, also can adopt it integrated, can also adopt gas control or hydraulic control one-way valve or its integrated.
Fig. 1 is the utility model automobile burglar, the anti-brake device structure scheme drawing of robbing;
Fig. 2 is the utility model automobile burglar, the anti-brake equipment control circuit schematic diagram of robbing;
Among Fig. 1,2: 1 car side brake, 2,4 high pressure fuel pipes 3 have the electromagnetism directional control valve 5 master brake cylinder 6 electromagnetism directional control valve coils of non-return valve function, R

Below in conjunction with accompanying drawing automobile burglar of the present utility model, the anti-brake equipment of robbing are described in further detail:
Automobile burglar of the present utility model, the anti-brake equipment circuit working principle of robbing are: N
2The coding plug-in unit of making, when inserting interface, decoding circuit N
1Output positive level signal is aerotron V
1Bias current makes aerotron V
1Conducting, electromagnetism directional control valve 3 are in electric attracting state, as encode circuit N
2Plug-in unit takes off from interface, then decoding circuit N
1Be output as 0 level, make aerotron V
1End, electromagnetism directional control valve 3 is in no electric release position.
Automobile burglar, the anti-brake equipment braking procedure of robbing is as follows: be in non-operative condition or automobile adopts antitheft at automotive engine, anti-rob that annunciator is on the alert or the ruined any situation of annunciator under, can both make the electromagnetism directional control valve be in the check valve mode of operation, have the people to steal car this moment, in the process of moving, must be with braking, when stepping on brake pedal 6, pull bar promotes the piston of master brake cylinder 5, high pressure oil is through high pressure fuel pipe 4, electromagnetism directional control valve 3 and high pressure fuel pipe 2 enter car side brake 1, because this moment, the electromagnetism directional control valve was in the check valve mode of operation, so high pressure oil can only enter car side brake and can't return, so car side brake is along with many more braking forces that high pressure oil advances are big more, reach at last car side brake wheel stop dead till, make the automobile can't be movable, reach the purpose of antitheft car and anti-robbing automobile.
If the robber destroys the electromagnetism directional control valve, must cause brake system failure, automobile also can't travel.
When automotive engine is in operative condition, or automobile adopts antitheft, when anti-misfortune annunciator is in disarm state, the electromagnetism directional control valve can both be in normal open state, at this moment, if step on brake pedal 6, pull bar promotes the piston of master brake cylinder 5, high pressure oil is through high pressure fuel pipe 4, electromagnetism directional control valve 3 and high pressure fuel pipe 2 enter car side brake 1, can brake car, therefore electromagnetic control direction valve 3 is in normal open state the time, so behind the loosen the brake 6, oil can be through oil pipe 2, electromagnetism directional control valve 3 and oil pipe 4 are got back to master brake cylinder 5, make car side brake decompression, declutch to reach normal brake application and with the purpose of car.
Compared with prior art, antitheft, anti-robbery brake apparatus of the present utility model has following advantage:
1, this device is difficult for being destroyed by the robber, uses reliably, has both just destroyed, and automobile also still can't travel because of brake system failure, has prevented from effectively that automobile is stolen to be robbed.
2, simple in structure, cost is low, and is easy to install.
If 3 have used the car of alarm, when alarm is malfunctioning, can prevent from still that automobile is stolen to be robbed.
