Abstract
The utility model discloses a theft-proof device for car stopping, which is composed of a brake master pump, a pipeline, a one-way valve, an electromagnetic valve, and a starting switch. One end of the pipeline is connected with the brake master pump, and the other end is connected a brake branch pump by the one-way valve and the electromagnetic valve; the magnetic coil of the electromagnetic valve is connected with the starting switch. The utility model has the advantages of reliable car stopping and theft protection; when the car stops, the starting switch is closed so that the brake can not be loosen; the car is kept in a brake state; a coil voltage in a starting switch corresponds to the voltage in a magnetic coil; when the coil voltage does not correspond to the voltage in the magnetic coil, the electromagnetic valve can not be opened; thus, the utility model avoids car stolen behaviors directly connecting a fire wire without starting switches.
Description
The utility model belongs to a kind of alarms and security systems for automobiles.
Present automobile does not all have check device in its brake system, loosen the brake, and braking liquid refluxes, and braking is removed.During parking, all with hand braking control, its braking effect is poor, when particularly loaded vehicle stops on the slope, does not hand brakingly work, and tends to have an accident or dangerous.
The purpose of this utility model is, provides a kind of stopping brake reliable and have the device of anti-theft feature, to address the above problem.
The utility model is to constitute like this: it is by master brake cylinder (1), pipeline (2), check valve (3), electromagnetic valve (4), starting switch (5) is formed, one end of pipeline (2) is connected with master brake cylinder (1), and the other end connects brake cylinder by check valve (3) and electromagnetic valve (4), and the magnetic coil (6) of electromagnetic valve (4) connects starting switch (5).
Also have coil (7) in starting switch (5), it is connected with magnetic coil (6) by starting switch.
Advantages such as the utility model compared with prior art has and stops reliably, and is antitheft.During parking, close starting switch, electromagnetic valve and check valve can not unclamp drg liquid in the brake cylinder (gas) body non-return, and automobile keeps braking mode.Coil voltage in the starting switch is corresponding with voltage in the magnetic coil, and coil and starting switch made a whole complete closed, when coil voltage and magnetic coil voltage not at once, electromagnetic valve can't be opened, thereby has prevented that not the robber garage that starts automobile by starting switch direct connection live wire is.
Fig. 1 is a schematic diagram of the present utility model;
Fig. 2 is the connection diagram of starting switch and coil.
Embodiment of the present utility model: an end of pipeline (2) is connected with master brake cylinder (1), and the other end connects brake cylinder by check valve (3) and electromagnetic valve (4), and the magnetic coil (6) of electromagnetic valve (4) connects starting switch (5).Starting switch (5) makes an integral body with coil (7), and complete closed, and coil (7) is connected with magnetic coil (6) by starting switch (5).
Claims (2)
1, a kind of parking of automobile anti-joyride device, it is by master brake cylinder (1), pipeline (2), check valve (3), electromagnetic valve (4), starting switch (5) is formed, and it is characterized in that: an end of pipeline (2) is connected with master brake cylinder (1), the other end connects brake cylinder by check valve (3) and electromagnetic valve (4), and the magnetic coil (6) of electromagnetic valve (4) connects starting switch (5).
2, parking of automobile anti-joyride device according to claim 1 is characterized in that: also have coil (7) in starting switch (5), it is connected with magnetic coil (6) by starting switch.
