[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spare threatening device installed in a vehicle to prevent theft or theft of the vehicle and an on-board burglar alarm device equipped with the preliminary threatening device.

[0002]

2. Description of the Related Art Conventionally, as an alarm device of this type, there is a vehicle antitheft device 100 disclosed in Japanese Patent Laid-Open No. 9-277873 as shown in a perspective view of FIG.

The anti-theft device 100 issues an alarm when the door is opened after being set to an operating state. The anti-theft device body 101, a remote controller 102, a sub switch 105, and an alarm means 108 are provided. ,
And a door opening / closing detection means (not shown).

The anti-theft device body 101 processes signals sent from the door opening / closing detecting means, controls driving of the alarm means, etc., and is a printed circuit board on which various electronic parts are mounted (none of which are shown). ) Is built in the case,
It forms the anti-theft control circuit. The remote controller 102 emits infrared rays to turn on the sub switch 105.
The switch is turned off and includes a push button 103 and an infrared light emitter 104. The sub switch 105 receives infrared rays emitted from the remote controller 102 and transmits a signal for turning on / off the anti-theft device body 101, and includes an infrared light receiver 106 and an ON display lamp (LED element) 107. ing. Warning means 10
Reference numeral 8 denotes a warning sound, which is composed of a speaker (not shown) or the like. The door opening / closing detection means (not shown) detects opening / closing of the door of the vehicle and outputs a signal, and is formed so as to interlock with a door switch or the like for lighting the room lamp.

Next, the anti-theft device 100 having the above structure.
The operation of will be described.

When operating the anti-theft device 100,
The push button 103 of the remote controller 102 is pushed toward the infrared receiver 106 of the sub switch 105. Then, the infrared emitter 104 of the remote controller 102
Infrared is emitted from the sub switch 105, the infrared receiver 106 of the sub switch 105 receives the infrared light, and the sub switch 10
5 sends an ON signal to the anti-theft device body 101.
As a result, the ON display lamp 107 lights up and
The anti-theft device 100 is set to the operating state. After that, when the thief opens the door of the car, a signal is sent from the door opening / closing detection means (not shown) to the anti-theft device body 101. The signal is processed by the anti-theft control circuit in the anti-theft device body 101, and the drive signal is output to the alarm means 108, so that an alarm sound is emitted.

When the anti-theft device 100 is released from its operating state, the infrared receiver 1 of the sub switch 105 is also used.
Push button 10 of the remote controller 102 toward 06
Press 3. Then, infrared rays are emitted from the infrared light emitter 104 of the remote controller 102, and the sub switch 1
The infrared light receiver 106 of 05 receives the infrared light.
As a result, from the sub-switch 105, the anti-theft device body 1
The OFF signal is transmitted to 01, and the operation state of the anti-theft device 100 is released.

[0008]

By the way, when the anti-theft device 100 is installed in a vehicle and actually functions as an on-board theft alarm device for preventing a vehicle theft or an on-board theft, a thief can detect the vehicle. After opening the door, the warning sound with a loud volume was emitted. In other words, when this warning sound is emitted, it means that the car window has already been damaged and the car door has been broken or the car door has been opened, and the car has been harmed. It will be.

In order to prevent this, the on-board theft alarm device is preferably provided with a function of threatening a thief before the vehicle is injured and driving it away. However, as described above, the anti-theft device 100.
Has only turned on the ON display lamp 107 that causes the sub switch 105 to confirm the operating state,
The thief couldn't be threatened enough. as a result,
It is not possible to prevent the thief from taking away the car, or trying to steal items left in the car,
It was feared that the car would be harmed.

As an on-board burglar alarm device, a flashing state of an optical display section using an LED element for displaying the operating state of the apparatus is periodically changed for the purpose of intimidating a thief. However, it is assumed that thieves cannot be threatened sufficiently because the blinking pattern of the display is not so varied.

There is also a method of preventing a car theft or a car theft by attaching a sticker described as "with a theft alarm device" to a window glass of a car door. However, the stickers are hard to see when it is dark, such as at night,
In fact, many cars only have stickers attached without anti-theft devices, so the threat of thieves could not be expected.

The present invention has been made in view of the above circumstances, and its purpose is to sufficiently intimidate a thief and steal a car, articles in the car, etc. only when the thief approaches the car. Another object of the present invention is to provide a spare threatening device and an on-board burglar alarm device equipped with the spare threatening device, which can prevent the vehicle from being damaged by a thief.

[0013]

In order to achieve the above-mentioned object, in a backup threatening device of the present invention, a detection unit for detecting the approach of a human body by detecting a change in physical quantity due to an object approaching toward the surroundings. And a control unit that processes a detection signal input from the detection unit and outputs a control signal, and an informing unit that executes a threatening notification to prevent the theft of the human body on the vehicle when the control signal is input. It is characterized by having and.

As a result, when the detection unit of the backup threatening unit detects a human body approaching the vehicle, the notification unit executes the threatening notification so as to prevent the vehicle theft.

Further, it is preferable that the detection unit is a distance measuring sensor for detecting a distance to the object, and the alarm level is variable according to the distance to the object. . As a result, when the distance measuring sensor detects the distance to the target object, the threatening notification of the notification level according to the distance to the target object is executed.

Further, the detection unit is constituted by an obstacle detection sensor installed in the vehicle in advance so as to detect an obstacle around the detection unit, and the output from the obstacle detection sensor is notified to the regular side and the threatening state. It is preferable to be able to switch between the threatening notification side to be executed. By doing so, the obstacle detection sensor can detect the approach of the human body by sensing the change in the physical quantity due to the object approaching the vehicle.

Further, it is preferable that a drive unit is provided which is driven for a preset period of time, and the notification unit is supplied with power from the drive unit. In this case, the notification unit executes the threat notification by the power supplied from the drive unit.

In addition, the on-board theft alarm device of the present invention includes the above-described backup threatening device, and instead of the notification unit, detection from the human body detection unit that detects a physical quantity change due to human body intrusion into the vehicle. It is characterized in that an alarm unit for inputting a signal and issuing an alarm notifies the threat. By doing so, it is possible to cause the alarm section of the on-board theft alarm device to execute the threatening notification.

The above-mentioned backup threatening device is provided, and instead of the notification unit, a detection signal from a human body detection unit for detecting a change in physical quantity due to human body intrusion into the vehicle is input to indicate an alarm issuing state. It is characterized in that the intimidation is notified by changing the blinking state of the optical display unit. In this case, the optical display unit performs the threatening notification by changing the blinking state based on the detection signal.
