Abstract

PURPOSE:To detect a moving body around a traveling body as an assailant by detecting the moving body around the traveling body while it is stopped with an infrared sensor. CONSTITUTION:A single or composite detection section 13 of an infrared, microwave or ultrasonic sensor is supported by its support tool 14 at the position where the desired detection range can be secured on the ceiling section of a traveling body 11 or at its front or read. A sucker type or magnetic attraction type connection section 15 is provided at one end section to facilitate the connection to the traveling body 11. The power source is secured from the socket of the cigarette lighter of the traveling body 11. When a moving body is detected, a signal is generated from a protective device, and a warning is generated from a preset alarm for a preset period.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a protection device for a traveling body.

0002

BACKGROUND OF THE INVENTION There is no known device designed exclusively to protect the exterior of a traveling body.

0003

[Problems to be Solved by the Invention] FIG. 1 shows a side view of the detection range 12 of the protection device for a traveling object 11 according to the present invention, and as shown in a plan view in FIG. It is characterized by detecting the signal and transmitting the signal to the inside of the vehicle or to a remote part by wire, wireless, acoustic or optical. With this, it is possible to detect the approach of a moving object (the assailant to the moving object) to the outer periphery of the moving object while being inside the moving object or at a remote location, and take more appropriate defensive measures in advance.
This is to protect the running body.

0004

[Means for solving the problem] As shown in FIG.
A single or combined detection unit 13 of an infrared, microwave, or ultrasonic type sensor is supported by its support 14 at a position where a desired detection range can be secured on the ceiling of 1 or the front and rear of the ceiling. One end thereof is provided with a suction cup type or magnetic attraction type joint part 15 for easy connection with the traveling body. However, we have omitted the detailed operating circuits of the various sensors because they can be satisfied with the structure similar to general security devices or human body detection automatic switches. If the device emits a signal from the moment the protection device is installed, it is convenient to delay it for a predetermined period of time in order to treat the owner as the perpetrator and issue a false alarm. In the same case, it would be convenient if the device could be operated from a remote location outside the detection range for the same reason as mentioned above.

The energy of infrared and ultrasonic sensors can be blocked by the glass window of the vehicle, and the detection range of microwave sensors can be set optically using a deflector. In other words, with the three types of sensors described above, even if there is an animal inside the vehicle, the sensor on the outer periphery will not falsely detect the movement inside the vehicle. Further, as the type of remote control medium, radio frequency, light, etc. can be used. That is, since radio waves and light in the radio frequency band can easily penetrate the glass windows of a vehicle, it is possible to operate the external protection device from the inside. Similarly, operations from a remote part outside the detection range will be omitted since they can be sufficiently satisfied with conventional methods.

[0006]

[Example] By combining an infrared sensor with a detection element made of a ceramic material having pyroelectricity and an optical system, the detection range of a moving object as shown in the side view of Fig. 1 is set, and the power source is a cigarette lighter of the moving object. When a moving object is detected, a signal is sent from the protection device for a predetermined period of time and a predetermined alarm is issued. Since the purpose of other types of sensors can basically be achieved using the same concept, a detailed explanation will be omitted.

[0007]

[Effects of the Invention] According to the present invention, by detecting a moving object on the outer periphery of a moving object as being an assailant, appropriate defensive measures can be taken before damage is caused, thereby protecting the moving object. can be expected.
