Description

[Technical field]

[0001] The present invention relates to a device for preventing theft of a motor vehicle and a method for mounting the device. [Background technology]

[0002] Recently, there has been an increase in car theft cases, especially of luxury cars, and in some cases cars are stolen within a few minutes. This is because cars are now started electronically, making it possible to start the car engine using special equipment. Patent Document 1 discloses a technology for starting a car engine using a relay switch that starts the engine only when a specified state is reached. However, this technology has a complex structure, and from the perspective of theft prevention, there is a problem in that it cannot be easily installed. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Publication No. S58-158842 Summary of the Invention [Problem to be solved by the invention]

[0004] The present invention aims to provide a simple device for preventing automobile theft and a method for installing the same. [Means for solving the problem]

[0005] The present invention (1) An anti-theft device for automobiles, characterized in that a touch sensor switch that can be turned on / off from the driver's seat is installed in any position on the dashboard on the engine side between the fuel pump and ignition system of the automobile, and the engine start can be controlled by turning the stealth sensor switch on / off. (2) An automobile anti-theft device as described in (1) above, characterized in that it has a stealth sensor switch that is operated by the vehicle power supply and a relay that receives an electrical signal from the vehicle power supply and turns the electrical circuit ON / OFF and switches it, thereby controlling the operation of the fuel pump and ignition system. (3) A method for installing an anti-theft device for an automobile, characterized in that a stealth sensor switch and a 4-pole relay are provided on the inside of the driver's seat and on the engine side between the fuel pump and the ignition device, which are operated by the vehicle power supply (ACC power supply), and the stealth sensor switch is wired to the vehicle body earth through the 4-pole relay, and the stealth sensor switch is wired to the fuel pump and the ignition device within the 4-pole relay, and when the stealth sensor switch is turned ON, electrical continuity is established between the fuel pump and the ignition device through the 4-pole relay, making it possible to start the engine. (4) A method for installing an anti-theft device for an automobile according to (3), further comprising providing an indicator for displaying the electrical continuity between the fuel pump and the ignition device. It is.

[0006] The stealth sensor switch of the present invention is installed in a location that cannot be seen from the outside, such as on the engine side of the driver's seat, and the 4-pole relay is also installed in a location that cannot be seen from the outside. The fuel pump operation is controlled by turning the stealth sensor switch ON / OFF by switching the 4-pole relay. Therefore, unless the stealth sensor switch is ON, the engine will not start, and since the position of the stealth sensor switch is known only to the driver, car theft by third parties can be prevented. Effect of the Invention

[0007] A stealth sensor switch is provided in a place not visible from the driver's seat, and the engine of the car will not start unless the switch is turned on, and a person who does not know the location of the stealth sensor switch cannot start the engine of the car, thereby preventing the theft of the car. [Brief description of the drawings]

[0008] [Figure 1] FIG. 1 shows the configuration of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] The present invention will now be described with reference to examples. EXAMPLES

[0010] A touch sensor type stealth sensor switch and a normally closed type four-pole relay are used, the stealth sensor switch is connected to the vehicle power supply, and one side of the switch is grounded. The stealth sensor switch is installed at the knee level on the left side of the driver's seat on the engine side (in this case, a right-hand drive vehicle). The four-pole relay is connected to the fuel pump and ignition power supply, and by turning the stealth sensor switch ON, the fuel pump and ignition power supply are directly connected via the four-pole relay, making it possible to start the engine. The engine cannot be started unless the stealth sensor switch is ON, and unless the position of the stealth sensor switch is known, it cannot be turned ON, making it impossible to start the engine of the car, and it has an anti-theft effect in that a third party cannot start the engine of the car and steal it.
