Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for preventing the theft of a vehicle.

[0002]

[Prior art]

 Some anti-theft devices for automobiles have a control unit that detects vibrations, shocks, and changes in current applied to the vehicle body when the vehicle is parked and parks the siren. Conventionally, two types of devices of this type have been known.

In the first conventional example, the control unit and the siren are separately configured, and the control unit provided near the driver's seat and the siren provided in the bonnet are connected by electrical wiring. In the second conventional example, the control unit and the siren are integrally configured and fixed to the outer surface of the dashboard inside the vehicle compartment.

[0004]

[Problems to be solved by the device]

 The separate device of the first conventional example has the following problems. The control unit near the driver's seat needs to be installed in a place where it does not interfere with the driving operation, which is troublesome to install. In addition, the siren must be installed in a narrow bonnet in a place that does not interfere with the maintenance of the engine, etc., so it takes time to install it. Moreover, since it is necessary to connect the control unit and the siren by electric wiring, it takes more work. Moreover, since the siren is installed inside the bonnet, it is difficult to hear the warning sound in an emergency, and it is necessary to make the siren relatively large and loud.

The integrated device of the second conventional example described above is excellent in that it can be easily mounted because it requires only one mounting place and electrical wiring for connection can be omitted, but it has the following problems. The integrated device, which is always fixed to the outer surface of the dashboard, further narrows the cabin space, which was originally a small space. Moreover, since a siren is installed in the passenger compartment, it is difficult to hear the alarm sound in an emergency. An object of the present invention is to solve all the problems of the above-mentioned conventional examples.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention has an anti-theft device configured as follows, for example, as shown in FIGS. 1 to 5. The control unit 13 operates the alarm generator 14 based on the control unit 13 detecting an emergency state such as an abnormal vibration applied to the parked vehicle 1 from the outside. In the prevention device, a connecting member 15 is provided to make the control unit 13 and the alarm generator 14 face each other with a predetermined gap, and the connecting member 15 is used as the upper edge of the openable window glass 5 of the automobile 1. It is configured such that it can be fitted onto the portion 5a from the upper side.

[0007]

[Action]

 The present invention operates as follows, for example, as shown in FIGS. The anti-theft device 6 is attached to the automobile 1 in the following procedure. First, the window glass 5 is lowered halfway, and in that state, the connecting member 15 is externally fitted to the upper edge 5a of the window glass 5 to position the control unit 13 inside the window glass 5 and the alarm generator 14 Is located outside the window glass 5. Next, in this state, the window glass 5 is raised. Then, the connector 15 is clamped and fixed between the upper edge 5a of the window glass 5 and the weather strip 11 of the door sash 8, whereby the control unit 13 is arranged in the vehicle compartment R. At the same time, the alarm generator 14 is exposed to the external space of the vehicle body 2. The anti-theft device 6 is detached from the automobile 1 by lowering the window glass 5 and pulling out the connecting tool 15 from the upper edge 5a thereof.

[0008]

[Effect of device]

 The present invention has the following effects because it is configured and operates as described above. The anti-theft device can be attached to a vehicle simply by fitting a connector onto the upper edge of the window glass from above and closing the window glass, so there is no need to choose the installation location and the installation is easy. . Further, the above-mentioned antitheft device can be detached from the automobile by simply pulling out the connecting tool from the upper edge portion of the window glass, so that the detaching operation is easy. Therefore, if the removed device is stored in, for example, the dashboard of the vehicle compartment, the vehicle compartment space cannot be reduced. Furthermore, since the alarm generator is exposed outside the vehicle, the alarm sound in an emergency can be heard well and a visual defense effect can be obtained.

[0009]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. First, the overall configuration will be described with reference to FIGS. 1 to 3. 1 is a cross-sectional view taken along the line I-I of FIG. 2, FIG. 2 is a side view of an automobile equipped with an anti-theft device, and FIG. 3 is a perspective view of the anti-theft device. As shown in FIG. 2, a door 4 is provided which covers the door opening 3 of the vehicle body 2 of the automobile 1 so as to be openable and closable, and an antitheft device 6 is attached to the openable window glass 5 of the door 4.

As shown in FIG. 1, the door 4 is hermetically fixed to the vehicle body 2 through a body seal 7 attached to an edge of the door opening 3 and a door seal 9 attached to a door sash 8. . The openable window glass 5 is attached to the door sash 8 via the weather strip 11 in a hermetically sealed manner.

As shown in FIG. 1 and FIG. 3 above, the anti-theft device 6 comprises a control unit 13 and a siren 14 which is an alarm generator. It is fixed in a state of being opposed to each other with a predetermined interval by the letter-shaped connecting tool 15. By closing the window glass 5 with the connecting tool 15 fitted onto the upper edge portion 5a of the window glass 5 from above, the upper edge portion 5a of the window glass 5 and the weather strip 11 are closed. The connector 15 is clamped between and. As a result, the control unit 13 is arranged in the vehicle compartment R, and the siren 14 is exposed to the external space of the vehicle body 2.

Next, the antitheft device 6 will be described in more detail with reference to the perspective view of FIG. 3 and the control block diagram of FIG. 4 above. The control unit 13 is attached to the window glass 5 (not shown here) with the main switch (not shown) provided on the back side of the control unit turned on (the same applies below), and the infrared remote control switch is installed from outside the vehicle. The push button 21 of 20 is turned on. Then, infrared rays are emitted from the light emitting device 24 via the modulator 23 based on the frequency preset by the transmitting side frequency setting device 22. When the light receiver 25 of the control unit 13 detects the infrared rays, the microcomputer 27 is operated via the demodulator 26, and the emergency alarm standby state is set.

In the standby state, when the vibration sensor 28 in the control unit 13 detects abnormal vibration, the microcomputer 27 sounds the siren 14. The demodulator 26 demodulates only the frequency preset by the receiving side frequency setting unit 29, and the frequency is set to the same value as that of the transmitting side frequency setting unit 22. Reference numeral 30 in FIG. 3 is a sensitivity adjustment switching switch.

As shown in FIG. 5, the transmission side frequency setting device 22 includes eight dip switches a to h. In the state shown in the figure, as shown in the (A) column in the figure, only switch a is turned on (on, the same below), and all other switches are turned off (off, the same below). The corresponding frequency is set. When setting other frequencies, as shown in column (B) of the figure, only switch b may be turned on and all other switches may be turned off, as shown in column (C) of the figure. Alternatively, only the switch c may be turned on and all other switches may be turned off.

As described above, by switching the above switches a to h to ON or OFF, 2 ⁸ = 256 different frequencies can be set. The reception side frequency setting device 29 is set in the same manner as the transmission side frequency setting device 22. As described above, the control frequency of the crime prevention device can be personalized, and the control unit 13 can be prevented from being erroneously operated or intentionally operated by the remote control switch 20 of another person.

The above embodiment can be modified as follows. The connector 15 may be any one that is fitted onto the upper edge portion 5a of the window glass 5, and may be formed in a shape such as an inverted inverted V shape or a W shape. The control unit 13 and the siren 14 need only be arranged to face each other with the window glass 5 sandwiched therebetween, and do not have to face each other in the vertical direction. Instead of the siren 14, the alarm generator may be another type such as a buzzer.

The window glass may be opened and closed inside and outside the vehicle body instead of being opened and closed in the vertical direction. The control unit 13 is for detecting a change in current or magnetic force flowing in the vehicle body 2 or a change in an infrared barrier provided outside the vehicle body, instead of detecting a vibration or impact applied to the vehicle body 2. Good.
