JP3035857U - Current drop sensor type automobile security device - Google Patents

Abstract

(57) [Abstract] An object of the present invention is to detect the presence or absence of an ignition key and a sensor for detecting a current drop to determine whether it is a theft or a mischief, and continuously generate a warning sound to prevent theft. Prevent mischief. SOLUTION: The present invention uses 2 vehicle body side sensors, 4 engine switch side sensors, 6 horns for generating warning sounds, 7 a computer for controlling them, and 8 batteries to generate warning sounds in the case of theft or mischief. Sounds to help prevent.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a crime prevention device for an automobile, which includes a sensor mounted on an automobile body and an ignition key, a horn for generating a warning sound, and a computer for controlling them.

[0002]

[Prior art]

 Until now, crime prevention devices, such as those that detect when the door is forcibly opened and those that detect when the air density inside the vehicle has changed, have only been able to sound a warning sound after the vehicle body is destroyed.

[0003]

[Problems to be solved by the device]

 Until now, the only crime prevention device that could sound a warning sound after the car body was destroyed by the criminal was that the owner of the car would incur the cost of repairing the car even if nothing was stolen, which would be a major expense. Become. Therefore, by making a warning sound when the vehicle body is touched, it is useful for crime prevention and attempts to eliminate the above-mentioned drawbacks.

[0004]

[Means for Solving the Problems]

 When the vehicle ignition key is not attached to the vehicle body, a small amount of current is sent to the vehicle body in advance, and if something touches the metal part of the vehicle body, the current is sensed and the alarm sounds. The problem is solved by continuously generating and alerting a person stealing or mischievous.

[0005]

[Embodiment of the invention]

 A sensor that measures the current drop is installed in the metal part of the car body, a sensor that detects whether or not the ignition key is present in the engine switch, a horn that emits a warning sound is installed in the engine room, and there is no ignition key. When the car body is touched at some time, a computer is installed inside the car that controls the horns to ring continuously, and power is drawn from the car battery so that the two can work together.

[0006]

【Example】

 Hereinafter, an embodiment will be described with reference to the accompanying drawings. 1 is the vehicle body, 2 is a sensor that detects when the current attached to the metal part of the vehicle body drops, 3 is an engine switch, 4 is a sensor on the engine switch side, 5 is an ignition key, and 6 is a horn that emits a warning sound. , 7 is a computer for controlling each, 8 is a car battery.

When the owner of the vehicle touches one vehicle body, the five ignition keys are inserted into the three engine switch. At this time, the current drop sensor type automobile security device is not operated.

When the 5 ignition key is not on the 3 engine switch, touching 1 vehicle body will detect the sensor on the 2 vehicle body side, and the sensor on the 4 engine switch side will also sense that there is no 5 ignition key, and the 7 control computer will Judge as stolen or mischievous, and continuously ring the 6-warning horn. The 6-warning horn stops when you move away from the 1 vehicle.

[0009]

[Effect of the invention]

 As mentioned above, if you touch the car body without the ignition key on the engine switch, it will be judged as theft or mischief and the warning horn will sound continuously to help prevent crime.
