Guide pieces (rollers) 19 and 20 are pivotally attached to the upper end portions (tip portions) of the lift arm 12 and the equalizer arm 18 so as to be rotatable and tiltable, respectively. Roller) 21 is pivotally attached.

  The guide piece 19 of the lift arm 12 and the guide piece 20 of the equalizer arm 18 are movably fitted to the window glass bracket 22, and the guide piece 21 of the equalizer arm 18 is located on the outside of the modular panel 6 in FIG. It is movably guided to an equalizer arm bracket (posture maintenance rail) 23 fixed to the surface.

  On the other hand, a window glass holder 24 is fixed to the lower edge of the window glass 5 at the front and rear thereof. The window glass holder 24 is fixed to the lower edge of the window glass 5 in advance, and the window glass 5 having the window glass holder 24 is inserted from the gap between the outer panel 2 and the inner panel 3, and the window glass bracket 22 is tightened by bolts 25. It is fixed to.

  As shown in FIG. 4, a pair of front and rear glass runs 26 are erected. The glass run 26 is made of a rubber material. The window glass 5 is movably supported by a pair of front and rear glass runs 26 as rail members. That is, the front and rear end portions of the window glass 5 are guided by the glass run 26 and can move up and down.

  When the pinion 16 is driven forward and backward via the electric drive unit 14 of FIG. 3, the lift arm 12 swings about the shaft 13 via the sector gear 15, and as a result, the window glass bracket 22 (window glass 5) is moved. The equalizer arm 18, the guide pieces 19, 20, 21 and the equalizer arm bracket 23 are moved up and down while being held in a substantially horizontal state. Thus, the window glass 5 is raised and lowered, and the opening 4 of the vehicle can be freely opened and closed by the window glass 5.

FIG. 5 shows a longitudinal section taken along line AA in FIG. In FIG. 5, the clip 40 and the buzzer module 50 of the automobile crime prevention device 30 are arranged inside the vehicle door 1.
In FIG. 8, the perspective view of the clip 40 and the buzzer module 50 is shown. 9A and 9B show the clip 40 and the buzzer module 50, where FIG. 9A is a front view and FIG. 9B is a cross-sectional view taken along line AA of FIG.

  In FIG. 5, the window glass 5 is disposed between the outer panel 2 and the inner panel 3 in a state of being sealed by a weather strip 7. A door trim 8 is disposed inside the inner panel 3. The clip 40 is disposed at the lower end of the window glass 5 and sandwiches the window glass 5.

  As shown in FIGS. 8 and 9, the clip 40 is configured by bending a single plate spring steel plate. The clip 40 includes first and second members 41 and 42 and a bent portion (connecting portion) 43 that face each other. The first member 41 on the back side has a rectangular shape, and the second member 42 on the front side has a square shape that is narrower than the first member 41. The window glass 5 is disposed between the first member 41 on the back side and the second member 42 on the front side, and the first member 41 and the second member 42 are urged toward the window glass 5 toward each other. .

  The bent portion 43 connects the first member 41 and the second member 42. The bent portion 43 is bent in two steps, and the width of the second-stage bent portion 43b is narrower than the thickness of the window glass 5, and the end surface of the window glass 5 is in contact with the bent portion 43a of the first step. That is, a stepped portion is formed in the bent portion 43 of the clip 40, the end surface of the window glass 5 is in contact with the stepped portion, and the lower end of the window glass 5 is not fitted (in the vicinity of the lower side portion). The window glass 5 is not sandwiched).

  A rectangular through hole 44 is formed at the center of the first member 41. The second member 42 is located at a position corresponding to the through hole 44. Projections 45 projecting to the front side are formed at the left and right upper corners of the first member 41, and are in contact with one surface (back surface 5b) of the window glass 5 at the tip of the projection 45 as shown in FIG. The second member 42 in FIGS. 8 and 9 is in contact with the other surface (surface 5 a) of the window glass 5 at a location corresponding to the inside of the through hole 44 of the first member 41. Therefore, the contact part with the window glass 5 in the 1st member 41 is provided so that it may be spaced apart in two places in the surface of the window glass 5, and the contact part with the window glass 5 in the 2nd member 42 may be pinched | interposed. Both contact portions of the first member 41 with the window glass 5 are connected around the contact portion of the second member 42 with the window glass 5. That is, the part facing the window glass 5 in the first member 41 has a reverse concave shape, and thus the window glass 5 is broken. The second member 42 is bonded to the window glass 5.

  Thus, in a state where the first member 41 and the second member 42 are in contact with each other at a position shifted in the plane of the window glass 5 between the first member 41 and the second member 42 where the window glass 5 is disposed. It is urged in the direction of approaching each other by its own elasticity. That is, force is applied to the window glass 5 at different locations on the front surface 5a and the back surface 5b of the window glass 5. Further, the clip 40 clamps (holds) the lower end portion of the window glass 5 with a predetermined force or more.

  A buzzer module 50 is attached to the first member 41 of the clip 40. The case 51 of the buzzer module 50 has a box shape having a predetermined thickness as an overall shape, and one surface of the case 51 is bonded to the first member 41 of the clip 40. A recess 51 a is formed on one surface (bonding surface) of the case 51. A protrusion-type push button switch 52 is provided on the bottom surface of the recess 51a so as to appear and retract. The push button switch 52 always protrudes, and this state is an off state. On the other hand, when the push button switch 52 is pressed, the switch is turned on.

  As shown in FIG. 2, the internal configuration of the buzzer module 50 includes a push button switch 52, oscillators 53 and 54, a buzzer sound signal generator 55, an identification sound signal generator 56, a power amplifier 57, and a speaker (buzzer) 58. I have. Oscillators 53 and 54 are connected to the push button switch 52. A buzzer sound signal generator 55 is connected to the oscillator 53. An identification sound signal generator 56 is connected to the oscillator 54. The output of the buzzer sound signal generator 55 and the output of the identification sound signal generator 56 are collected and connected to the speaker 58 via the power amplifier 57. Further, the buzzer module 50 is provided with a battery (power source) (not shown).

  As shown in FIG. 2, the glass breakage determination circuit 60 includes a microphone 61, bandpass filters 62 and 63, a buzzer sound determination circuit 64, an identification sound determination circuit 65, and an AND gate 66. The microphone 61 collects sound emitted from the speaker 58 of the buzzer module 50. A bandpass filter 62 and a bandpass filter 63 are connected to the microphone 61. A buzzer sound determination circuit 64 is connected to the band pass filter 62. An identification sound determination circuit 65 is connected to the band pass filter 63. An AND gate 66 is connected to the buzzer sound determination circuit 64 and the identification sound determination circuit 65. The AND gate 66 of the determination circuit 60 is connected to the security ECU 70 via an in-vehicle cable.

Next, an operation of the automobile crime prevention device 30 configured as described above, that is, an operation when the window glass 5 is broken (broken) will be described.
In normal times, when the occupant leaves the vehicle, the window glass 5 is fully closed or slightly opened by a few centimeters. Further, the clip 40 disposed at the end of the window glass 5 sandwiches the end of the window glass 5. Specifically, the window glass 5 is sandwiched between the first member 41 and the second member 42 by the elastic force of the clip 40 itself. Further, the push button switch 52 of the buzzer module 50 is not pressed and is in an off state.

  If the window glass 5 is broken from this state, the strength thereof is lowered. That is, when a part of the window glass 5 made of tempered glass is broken, as shown in FIG. 10, the window glass 5 is cracked and the strength is significantly reduced (the glass strength is reduced when the glass is broken).

  As the strength decreases, the clip 40 crushes the end portion (lower end portion) of the window glass 5 by its clamping force as shown in FIG. That is, the window glass 5 made of tempered glass is partially and completely pulverized (pulverized) by its own spring force.

  Specifically, as shown in FIG. 10, the window glass 5 is pushed by the urging force of the second member 42 and comes into contact with the first member 41 of the clip 40. In this state, the window glass 5 is pressed by the second member 42 in a state where the periphery of the through hole 44 is supported, and the window glass 5 in the through hole 44 is shattered as shown in FIG. 5 is broken into an inverted U shape).

  Then, the window glass breakage detection clip 40 pulverizes in a partial region of the window glass 5 to detect breakage of the window glass 5. In this way, if the tempered glass is partially broken, it can be cracked and the strength is remarkably reduced, so that undetected and erroneous detection can be minimized.

  Further, as shown in FIG. 4, it is possible to detect breakage of the window glass 5 even when the window glass 5 is not in the fully closed position. Specifically, in the prior art (Patent Document 1), since the movement of the window glass when the window glass was fully closed was detected, it was not possible to detect breakage of the window glass when the window glass was not in the fully closed position. In this embodiment, it is possible to detect breakage of the window glass even when the window glass is slightly opened for ventilation or the like and the window glass is not in the fully closed position.

  Moreover, the clip 40 of FIG. 9 has the 1st member 41 and the 2nd member 42 which bent and opposed the steel plate for leaf | plate springs, and between the 1st member 41 and the 2nd member 42 in which the window glass 5 is arrange | positioned. In a state where the first member 41 and the second member 42 are in contact with each other at a position shifted in the plane of the window glass 5, they are biased in opposite directions to the glass surface by their own elasticity (in directions approaching each other) Energized). As a result, a force is applied to the window glass 5 at different locations on the front surface 5a and the back surface 5b of the window glass 5, so that the window glass is accompanied by breakage of the window glass 5 (with a decrease in the strength of the window glass 5). It is possible to reliably detect the breakage of the window glass 5 by reliably crushing the end portion of the window 5.

  Further, the contact portion of the first member 41 of the clip 40 of FIG. 9 with the window glass 5 is separated from the contact portion of the second member 42 with the window glass 5 in the plane of the window glass 5 and the first member. Both contact portions with the window glass 5 in 41 are connected around the contact portion with the window glass 5 in the second member 42. Therefore, as shown in FIG. 10, the window glass 5 is pressed in a state where the window glass 5 is in contact with the first member 41 around the contact portion of the second member 42 with the window glass 5. That is, in the first member 41, the window glass 5 is pressed inside the inner periphery of the through hole 44 in a state where the window glass 5 is supported around the through hole 44. Thereby, as shown in FIG. 11, the edge part of the window glass 5 can be grind | pulverized easily.

  On the other hand, as described above, when the clip 40 pulverizes in a partial region of the window glass 5, the second member 42 returns to the original state by the elastic force of the clip 40 as shown in FIG. At this time, the second member 42 presses the push button switch 52 of the buzzer module 50. As a result, the push button switch 52 is turned on.

When the push button switch 52 of the buzzer module 50 is turned on, the buzzer module 50 of FIG. 2 operates as follows.
When the push button switch 52 in FIG. 2 is turned on, a signal is sent from the oscillator 53 to the buzzer sound signal generator 55 to generate an alarm sound signal (buzzer sound signal). When the push button switch 52 is turned on, a signal is sent from the oscillator 54 to the identification sound signal generator 56 to generate an identification sound signal. Then, the identification sound signal by the identification sound signal generator 56 is added (added) to the alarm sound signal (buzzer sound signal) of the buzzer sound signal generator 55, amplified by the power amplifier 57, and output as a sound from the speaker 58. Is done. That is, the window glass breakage detection identification sound is added to the alarm sound and output from the speaker 58. At this time, a sound of 100 dB or more is emitted from the speaker 58 to the surroundings. As a result, the person who broke the window glass is directly intimidated and informed to the surroundings.

  FIG. 7A shows an alarm sound signal (buzzer sound signal), and FIG. 7B shows an identification sound signal. In comparison between the waveform of the alarm sound signal (buzzer sound signal) and the waveform of the identification sound signal, the identification sound signal has a longer period than the alarm sound signal (buzzer sound signal). For example, the frequency of the identification sound signal is about 1000 Hz. FIG. 7C shows a signal after the alarm sound signal (buzzer sound signal) and the identification sound signal are added. As shown in FIG. 7C, an identification sound signal is added (superimposed) to the alarm sound signal (buzzer sound signal). That is, it is modulated and output from the speaker 58.

The sound emitted from the speaker 58 of the buzzer module 50 is taken into the microphone 61 of the determination circuit 60 in FIG. 2, and the determination circuit 60 operates as follows.
The sound emitted from the speaker 58 of the buzzer module 50 is converted into an electric signal by the microphone 61 (see FIG. 7C). The frequency component of the alarm sound signal (buzzer sound signal) in the electric signal from the microphone 61 is extracted by the band pass filter 62. That is, the component of FIG. 7A is demodulated with respect to FIG. Further, the frequency component of the identification sound signal in the electric signal from the microphone 61 is extracted by the band pass filter 63. That is, the component of FIG. 7B is demodulated with respect to FIG.

  The buzzer sound determination circuit 64 determines the presence or absence of an alarm sound (buzzer sound) from the period and intensity of the signal from the bandpass filter 62. In addition, the identification sound determination circuit 65 determines the presence or absence of the identification sound from the period and intensity of the signal from the band pass filter 63. That is, the window glass breakage detection identification sound is extracted from the sound collected by the microphone 61, and thereby the breakage of the window glass can be detected. The determination result by the buzzer sound determination circuit 64 and the determination result by the identification sound determination circuit 65 are sent to the AND gate 66. In the AND gate 66, when an alarm sound (buzzer sound) is detected by the buzzer sound determination circuit 64 and an identification sound is detected by the identification sound determination circuit 65, it is determined that the window glass is broken, and this is indicated. It is sent from the gate 66 to the security ECU 70 via the in-vehicle cable. The security ECU 70 notifies the management station outside the vehicle or the like to the owner of the vehicle by wireless communication or the like.

  In this manner, the push button switch 52 of the buzzer module 50 is turned on in conjunction with the crushing operation in the partial region of the window glass by the clip 40 accompanying the breakage of the window glass 5, and the breakage of the window glass is detected using the sound. To the determination circuit 60. That is, the buzzer module 50 modulates an alarm sound and an audible sound identification sound that becomes a window glass breakage detection signal and outputs the modulated sound from the speaker 58, and the determination circuit 60 demodulates the sound received by the microphone 61 to display the window. Extract glass breakage detection signal. Therefore, since the communication uses a large volume, it is difficult to be disturbed. In addition, in order to disturb the system, a loud sound is required, so that the person who broke the window glass cannot make the sound unless he / she makes a sound himself (disturbing work is difficult).

  Furthermore, since the identification sound is added to the alarm sound emitted from the buzzer module 50, it is preferable as a countermeasure against false alarms and mischief such as an alarm. Further, since the buzzer module 50 is mounted on the clip 40, wiring is not necessary.

According to the above embodiment, the following effects can be obtained.
(1) The automobile crime prevention device 30 includes a clip 40 as a window glass breakage detector and a buzzer module 50 as an alarm device. The clip 40 as a window glass breakage detector is attached to the window glass 5 of the vehicle, and is urged by its own elasticity at a position shifted in the plane of the window glass 5, so that the window glass accompanying the breakage of the window glass 5. The breakage of the window glass 5 is detected by crushing in a partial area 5. The buzzer module 50 as an alarm device is provided in the clip 40 and operates when the clip 40 crushes in a partial region of the window glass 5 to output an alarm sound. Therefore, even when the window glass 5 remains without being completely pulverized as the window glass 5 is broken by using the window glass breakage detection clip 40, the breakage of the window glass 5 can be reliably detected. Further, the buzzer module 50 is provided in the clip 40, and the buzzer module 50 is activated by the clip 40 being crushed in a partial region of the window glass 5, and outputs an alarm sound. Therefore, it is possible to output an alarm sound cordlessly and improve the degree of freedom of installation. Moreover, the member which detects the displacement etc. accompanying the grinding | pulverization of the partial area | region of the window glass 5 in the clip 40 can be made unnecessary.

  (2) Here, the buzzer module 50 as an alarm device includes a switch 52, and the second member 42, which is a part of the clip 40, is displaced by the crushing operation of the clip 40, and the switch 52 is turned on to generate an alarm sound. Since it outputs, an alarm sound can be reliably output with few members.

  (3) The automobile crime prevention device 30 includes a clip 40 as a window glass breakage detector, a buzzer module 50 as a wireless transmission means, and a determination circuit 60 as a wireless reception means. The buzzer module 50 as a wireless transmission means is provided in the clip 40 and operates when the clip 40 crushes in a partial region of the window glass 5 to transmit a window glass breakage detection signal. The determination circuit 60 as a wireless receiving means is mounted on the vehicle and receives a window glass breakage detection signal from the buzzer module 50 to detect breakage of the window glass 5. Therefore, in addition to the function and effect of the window glass breakage detection clip 40 in (1), a buzzer module (wireless transmission means) 50 is provided in the clip 40, and the clip 40 is a partial area of the window glass 5. As a result, the buzzer module (wireless transmission means) 50 is activated to transmit a window glass breakage detection signal. Then, the determination circuit (wireless receiving means) 60 mounted on the vehicle receives the window glass breakage detection signal.

(4) Here, the buzzer module 50 as a wireless transmission means is provided with a switch 52, and the second member 42 which is a part of the clip 40 is displaced by the crushing operation of the clip 40, and the switch 52 is turned on to open the window. Since the glass breakage detection signal is transmitted, the window glass breakage detection signal can be reliably transmitted with a small number of members.
