Description

  The present invention relates to a vehicular alarm device, and more specifically to a type attached to a rearview mirror.

  Some in-vehicle devices installed in the vehicle are pre-assembled in the corresponding part of the dash panel at the time of factory shipment, etc. However, in the case of aftermarket products for optional equipment, it may not be possible to secure the assembly part in the dash panel. Is almost. One of the on-vehicle equipment of such aftermarket products is to detect the microwave transmitted from the vehicle speed measuring device, or to store the position information of the vehicle speed measuring device, and to detect the vehicle detected by GPS. 2. Description of the Related Art There is known a vehicle alarm device that informs that a vehicle speed measuring device is approaching when the host vehicle approaches the vehicle speed measuring device from a position. These vehicle alarm devices inform the driver of the approach to the position of the vehicle speed measuring device, thereby contributing to preventing the driver from unintentionally giving too much speed. In particular, since the vehicle speed measuring device is generally installed in a place where the speed is likely to be exceeded, it is possible to alert the driver to the overspeed in a dangerous place. .

  Many of such in-vehicle devices often employ an arrangement in which they are fixed on a dashboard using an in-vehicle support disclosed in Patent Document 1 or the like for convenience of operation by the driver. There is also a mirror type that is attached to a room mirror (also referred to as a rearview mirror) installed in front of the interior of the automobile (near the upper center of the windshield). The mirror type vehicle alarm device has a mirror part disposed almost entirely on the front side, a display part for notifying an alarm in a part of the mirror part, and a rear side. A configuration is provided in which a fixing clamp is provided. The fixing clamp has a moving claw portion urged downward by a spring or the like on the upper side of the case, and has a fixing claw portion on the bottom side. In order to attach this mirror type vehicle alarm device to the genuine room mirror that comes standard with the vehicle, set it from the front side where the mirror part of the genuine room mirror is placed, cover the mirror part and place it vertically The upper and lower surfaces of the genuine rear mirror are sandwiched and fixed by the moving claw and fixed claw.

  However, the above various vehicle alarm devices have the following problems. That is, all types are exposed, and the presence in the passenger compartment increases. Therefore, especially when a sense of unity is taken with a certain direction, such as in a luxury car, installing a vehicle warning device with a presence presents a problem of impairing the unity. is there.

  Furthermore, since a mirror type thing is arrange | positioned so that the mirror part of a room mirror may be covered, when a room mirror is a glare-proof mirror, the subject that the said glare-proof function cannot be exhibited also exists. Furthermore, the mirror type vehicle alarm device that covers the entire surface of the rearview mirror is more noticeable in size and shape than the rearview mirror, and may not be unified with the vehicle that has the design installed, and is installed on the dashboard. As with the type, there remains the problem of losing a sense of unity. Furthermore, since the mirror type is heavy, it not only has the possibility of changing the direction of the mirror due to the vibration of the running vehicle, but also the structure of sandwiching from the top and bottom with a clamp. If it is not attached to, there is a risk of falling during travel.

  In order to solve the above-described problems, an alarm device for a vehicle according to the present invention includes (1) a radio wave receiving unit that receives radio waves, an alarm unit that issues an alarm based on the radio waves received by the radio wave receiving unit, The housing includes a fixing means for fixing the rear surface of the rear mirror of the vehicle. In the embodiment, the radio wave receiving means corresponds to the microwave receiver 5, the radio receiver 6 and the GPS receiver 7. Thus, it is not necessary to arrange all three receivers, and one or two receivers may be used, or a receiver that receives another radio wave may be used.

  Unlike a vehicle alarm device mounted on a general rearview mirror, it is arranged on the rear side of the rearview mirror, that is, on the front side of the vehicle (between the windshield). As a result, the entire casing or most of the casing is hidden by the rearview mirror, becomes inconspicuous, does not enter the driver's / passenger's field of view, and has a good aesthetic appearance. In addition, it does not interfere with driving because it does not enter the driver's view. Furthermore, in luxury cars, etc., there is a heat insulating material other than around the windshield room mirror and it is difficult for radio waves to pass through.However, since the vehicle alarm device of the present invention is attached to the rear surface of the room mirror, the heat insulating material is It can receive with high sensitivity because it faces / closes to a non-existing area. Furthermore, since the alarm device for vehicles is attached to the back surface of the room mirror, the mirror part of the room mirror is not covered, and the rear can be confirmed by the mirror part. Therefore, when the room mirror has an antiglare function, the antiglare function can be exhibited.

  (2) The fixing means may be an attaching member that is attached to the back surface. Examples of the affixing member include a hook-and-loop fastener and a double-sided adhesive tape. When the pasting member is used in this way, it can be easily fixed and can be fixed without any problem even if the size of the casing is smaller than that of the rear mirror. Furthermore, in the case of a hook-and-loop fastener, the fasteners of both the male and female hook-and-loop fasteners have a predetermined height, and the male and female fasteners have adhesive strength within the height range. Therefore, for example, even when the rear surface of the rearview mirror is configured with a curved surface, even when the mounting surface of the vehicle alarm device is a flat surface, the curved surface is absorbed and has adhesive strength within the height range. Further, the hook-and-loop fastener functions as a cushion, can absorb the vibration of the vehicle that occurs during running, idling, etc., and can suppress the shakiness of the housing.

  (3) A remote control receiver may be provided, and a light receiving portion of the remote control receiver may be disposed on at least one of the lower surface of the casing and the side surface on the driver's seat side. Of course, it does not prevent you from placing both. The vehicle alarm device is hidden behind the rearview mirror, but in any case, the remote control responds better.

  (4) At least one of a power switch and a lamp may be disposed on the lower surface of the housing. Even if the entire vehicle alarm device is hidden behind the rearview mirror, if the power switch is placed on the lower surface of the housing, the switch can be operated by reaching from the bottom of the rearview mirror, making it easier to operate the power supply. Become. Similarly, by arranging the lamp on the lower surface, even if the lamp cannot be seen directly, light is emitted toward the lower part of the rear mirror, so that the light emission state can be easily confirmed. Further, in any case, it is preferable because it is easy to operate and visually recognize the vehicle with either the left or right handle.

  (5) It is preferable that an opening of a card slot for mounting a detachable recording medium is disposed on a side surface or a lower surface of the housing. If the card slot is provided on the side surface (especially the side surface on the driver's seat side) or on the lower surface, the opening can be easily reached and the memory card can be easily inserted and removed.

  (6) A speaker that outputs an alarm may be provided, and an opening for emitting sound output from the speaker to the outside may be provided on at least one of the lower surface of the housing and the side surface on the driver's seat side. If an opening is provided on the lower surface, the sound is output downward, making it easy to listen. In addition, if it is provided on the driver's seat side, an alarm is issued to the driver, so that there is an advantage that the passenger in the passenger seat will not be disturbed.

  (7) The height and width of the casing may be shorter than the height and width of the room mirror. In this case, the vehicle alarm device can be hidden behind the rear-view mirror as long as there is no extreme depth (length in the front-rear direction), depending on the degree of depth.

  (8) The width of the housing may be shorter than half the width of the room mirror. The vehicular alarm device is more compact, and even if it is arranged so as to be biased to one side of the rear surface of the rearview mirror, it is smaller and lighter, so that the posture of the rearview mirror can be maintained without changing.

  (9) A power supply DC jack is provided, and the relationship between the force required to pull out the DC plug from the state where the DC plug is attached to the DC jack and the weight of the main body The weight may be set so that the DC plug does not come out of the DC jack when dropped from the mirror. In this way, even if the vehicle alarm device is detached from the rearview mirror, it does not have to come off from the DC plug. Therefore, by fixing the wiring cord following the DC plug to the inner wall surface in the vehicle interior, it is possible to prevent the vehicle alarm device detached from the room mirror from suddenly dropping down.

  (10) When the DC jack is provided on the side surface of the casing, the DC plug uses an L-shaped plug, and when the DC jack is provided on the top surface of the casing, the DC plug is I A character plug should be used. This is preferable because the wiring cord following the DC plug can be smoothly routed upward, the wiring can be easily hidden, and the appearance is also clean.

  (11) The power supply line may be drawn from the upper surface of the casing. In this case, the power supply line may be directly connected to the housing, or a connection portion such as a jack or a connector for connecting the power supply line may be disposed on the upper surface. By disposing on the upper surface in this way, the feeder line (wiring cord) can be more smoothly routed to the upper surface of the vehicle and wired.

  (12) A strap attachment portion may be provided in the housing. Attaching one end of the strap to the strap attaching portion and hooking the strap on the rear mirror post can prevent the fall.

  (13) When a remote control receiver is provided, the light receiving portion of the remote control receiver is disposed on the front surface of the housing, and the light output from the remote control is reflected by the windshield and received by the light receiving portion. Good.

  (14) A display unit may be provided, and the display unit may protrude outward from the periphery of the room mirror in a state where the housing is attached to the rear surface of the room mirror. The amount of information to be notified can be increased by issuing a warning by the display unit. Even in such a case, most of the vehicle alarm device is hidden by the rearview mirror and is clean, and the mirror portion of the rearview mirror is not hidden.

  (15) The display screen of the display unit may be arranged so as to protrude from a mounting surface of the housing to the room mirror. If it does in this way, since a display screen will approach a driver side more, it will become easy to see.

  (16) The housing may be composed of two cases, and the two cases may be attached to both the left and right sides of the rear mirror support. If it does in this way, it can arrange | position with sufficient weight balance.

  (17) The two cases are connected by a connection cable, and the length of the connection cable is such that the upper side of the support can be passed with the two cases attached to the rear surface of the rearview mirror. Good. By doing so, since the connection cable is caught by the support column, even if one or both cases are detached from the rear surface of the rearview mirror, it is possible to prevent the case from falling off immediately. The connection cable is preferably covered with a tube / cylinder or the like because the strength is increased.

  (18) On the premise of the above inventions (16) and (17), one of the two cases may include a display unit.

  According to the present invention, since the vehicular alarm device is hidden behind the rear-view mirror, the vehicle interior can be made clear and the vehicle interior can have a sense of unity. In addition, forward visibility is improved.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described with reference to the accompanying drawings. 1 to 4 show the appearance of a preferred embodiment of a vehicle alarm device according to the present invention. FIG. 5 shows functional blocks inside the vehicle alarm device 1, and FIG. It is the external view seen from position.

  The vehicle alarm device 1 according to the present embodiment is installed by being attached to a rearview mirror, and is a flat and rectangular case main body 2 having one open surface, and a lid 3 that closes the opening of the case main body 2. The housing 4 is configured by the above. The housing 4 has a simple rectangular box shape. Various input means, control means, output means, and the like are mounted in the housing 4. A microwave receiver 5 that detects microwaves in a frequency band emitted by the speed measurement device inside one half of the front side of the case body 2 (the side that is disposed forward of the vehicle (the vehicle windshield side)), A radio receiver 6 that receives radio waves is arranged. The antennas of the receivers 5 and 6 are planar antennas and are arranged in parallel with the lid 3. This is preferable because it can be efficiently stored in the thin case body 2. In addition, a GPS receiver 7 is arranged at a predetermined internal position on one half surface opposite to the area where the receivers 5 and 6 on the front side of the case body 2 are mounted. The GPS antenna that constitutes the GPS receiver 7 is preferably arranged so as to be inclined obliquely upward. For example, as shown in FIG. 3A, when the upper surface 2a of the case body 2 is inclined, if the GPS antenna is arranged along the inner wall of the upper surface 2a, the case body 2 is directed obliquely upward. be able to. Of course, it is not necessary to make it parallel to the inclination of the upper surface 2a (inner wall), the inclination angle can be arbitrary, and the size and shape of the GPS antenna is smaller than the internal space above the case body 2 May be arranged so as to face directly above. Although not specifically shown, each receiver includes an antenna and a receiving circuit. An output signal based on reception by each receiver is given to the control unit 18.

  A DC jack 8 and a memory card slot 9 are disposed on one side surface 2 b of the case body 2. The side surface 2b on which these are arranged is the left side surface, that is, the side surface 2b positioned on the driver side when the vehicle alarm device 1 is mounted on the rearview mirror. The DC jack 8 is connected to an internal power circuit, and supplies power to each part in the vehicle alarm device 1 through the power circuit. The DC jack 8 is provided with a DC plug 22 connected to the tip of the power supply direct connection cord 21 (see FIG. 6), and the other end of the power supply direct connection cord 21 is connected to a vehicle battery. Thereby, the alarm device 1 for vehicles receives electric power supply from the battery. Connection to the battery can be made by connecting to an accessory (ACC) power supply direct connection cord linked to engine start / stop, or by connecting to a predetermined terminal of the fuse box. It can be carried out. The memory card slot 9 has an opening for the side surface 2b. The memory card 10 can be detachably attached to the memory card slot 9 from its insertion slot. The memory card 10 is, for example, a micro SD card.

  Data stored in the memory card 10 inserted in the memory card slot 9 can be taken in. More specifically, the data stored in the memory card 10 includes update information such as information on a new target for performing an alarm based on position information (position information including longitude and latitude, type information, etc.) The update information is stored (downloaded) in the database 19 built in the apparatus via the control unit 18, and the data is updated. Of course, in addition to such data update, it can also be used to download programs for adding functions and upgrading versions.

  In the data update process, for example, the power switch 11 is operated and the vehicle alarm device 1 is turned off, and the memory card 10 in which the update data is stored is inserted into the memory card slot 9. In this state (see FIG. 7), the power is turned on. Thereby, the control unit 18 checks whether or not the memory card 10 is inserted in the memory card slot 9 as a process at the time of turning on the power. That is, the control unit 18 first accesses the memory card 10 to authenticate that it is a regular memory card for data update, and if it is legitimate, reads the stored data and performs data update processing. When the update is completed, the control unit 18 emits a sound (sound) notifying the end from the speaker 13. Thereafter, the control unit 18 executes normal initial processing and starts up the system. Also, if the installed memory card is a memory card that stores data for a different model, or if it is for this model, if the version is the same or older, it will end with an error and return to normal Execute the process and start up the system. In particular, in the vehicle alarm device 1 according to the present embodiment having no display unit, even if a memory card is mounted after the power is turned on, it is troublesome to appropriately perform data update processing by a remote control operation. This is convenient because the data can be automatically updated by turning on the power with the.

  The database 19 is a nonvolatile memory (for example, EEPROM) in the microcomputer of the control unit 18 or externally attached to the microcomputer. In the database 19, information related to a certain target is registered at the time of shipment, and data and the like regarding the target added after that can be updated as described above.

  On the lower surface 2 c side of the case body 2, a power switch 11, a lamp 12, a speaker 13, and an infrared light receiving unit 16 a of a remote control receiver 16 are provided. The power switch 11 is a slide switch that moves in the left-right direction, and is turned on when turned on. The lamp 12 indicates the state of a device such as power ON / OFF and GPS reception. Specifically, the lamp 12 is turned off when the power is off, and the lamp 12 is turned on when the power is turned on. . In addition, after the power is turned on, the lamp 12 blinks during searching by the GPS receiver 7 and during an alarm based on GPS. Further, the blinking pattern during the search and the blinking pattern during the alarm may be the same or different. If you want to make a difference, it is better to make the warning flash in a shorter cycle and draw attention. In addition to the alarm based on GPS, the lamp 12 may be blinked in an appropriate pattern in the case of an alarm based on the microwave receiver 5 and / or the wireless receiver 6. Furthermore, different color LEDs may be prepared to change the color development.

  The speaker 13 is a small high-quality speaker. That is, in order to reduce the size and weight of the vehicle alarm device 1, a small speaker is used. Furthermore, since the display unit is not provided, the main notification means is sound for alarm / guidance notification. Therefore, it is easy to listen by notifying with high-quality sound. The synthesized speech generated and output by the control unit 18 also uses a high sound quality speech synthesis IC.

  The remote control receiver 16 performs data communication with a remote control (portable device: handset) 17 by infrared rays and performs various settings for the device. As shown in FIG. 8, the remote controller 17 has a flat rectangular shape, and is provided with an infrared light emitting portion 17a in the center of the front surface and a battery holder 17b on the rear surface side. On the top surface of the remote controller 17, function buttons 17c and test & mute buttons 17d are arranged on the left and right sides on the front side. In addition, an up button 17e and a down button 17f are arranged on the front and rear, and a cancel button 17g and an area button 17h are arranged on the left and right so as to form a cross in the center of the upper surface of the remote controller 17. Further, a mode button 17 i is arranged on the rear side of the upper surface of the remote controller 17. When each button is pressed, the remote controller 17 transmits a code for specifying the pressed button. The code is given to the control unit 18 via the remote control receiver 16 of the vehicle alarm device 1, and the control unit 18 performs setting according to the code.

  An example of the setting is as follows. The up button 17e is used when the volume is increased or a function to be set is selected, and the down button 17f is used when the volume is decreased or a function to be set is selected. As a function to be set, there is a function for individually selecting a type for issuing an alarm based on signals received by various receivers 5, 6, and 7. The types of alarms are arranged in a predetermined order, and the control unit 18 selects the type of alarm to be set every time it recognizes that the up button 17e / down button 17f has been pressed once. Switch items. And in this embodiment, since there is no display part, whenever it switches, the control part 18 selects the selection items (N system, accident frequent occurrence area, radio | wireless, ...), such as the kind of alarm used as the selection object, and the speaker 13. Use to notify by voice. When the control unit 18 recognizes that the function button 17c has been pressed in this state, the control unit 18 shifts to the setting mode. When the control unit 18 recognizes that the mode button 17i has been pressed after shifting to the setting mode, the control unit 18 switches the current mode (whether to issue an alarm). That is, if it is “ON”, it is “OFF”, and if it is “OFF”, it is “ON”. And the control part 18 alert | reports the mode after switching with an audio | voice with the switching of the mode which concerns. For example, “XX is ON” / “XX is OFF” (XX is a selection item such as an alarm type) is notified. If the mode button 17i is pressed again in this state, the mode is switched back to the original state.

  Further, whenever the up button 17e / down button 17f is pressed and the selection item is switched, or when the function button 17c is pressed and the mode is shifted to the setting mode, the control unit 18 displays the current alarm to be set. The mode may be notified by voice. By doing so, the user can confirm the current state, and if that is OK, the user can press the up button 17e / down button 17f once to move to the next selection item, and is useless such as pressing the mode button 17i. Processing can be omitted.

  Further, when the buttons 17e and 17f are pressed for a short time, the selection items are switched as described above. When the buttons 17e and 17f are pressed for a certain time (for example, several seconds), the volume is changed. Can be done. Of course, the change in switching between the selected item and the volume change is not limited to the difference between the short press and the long press as described above. When the button 17e / down button 17f is pressed, the volume is increased / decreased by one level each time the button 17e / down button 17f is pressed, and functions as a setting target switching button in a normal operation after the volume adjustment period ends. You may do it.

  Recognizing that the test & mute button 17d has been pressed, the control unit 18 outputs an alarm sound or activates a mute function. Which process is executed can be performed, for example, by changing how the test & mute button 17d is pressed.

  The cancel button 17g and the area button 17h are used as alarm options based on the current position information detected by the GPS receiver 7. When the control unit 18 recognizes that the cancel button 17g has been pressed, the position at that time Information is acquired from the GPS receiver 7, and a predetermined range with the current position as a reference is set as a cancel region. After that, even if a microwave of a predetermined frequency is received by the microwave receiver 5, the microwave is received. Control based alarms not to be issued. On the contrary, when the control unit 18 recognizes that the area button 17h has been pressed, the control unit 18 acquires the position information at that time from the GPS receiver 7 and registers it as an alarm point. Thereafter, the control unit 18 issues an alarm when approaching the alarm point.

  Furthermore, in the present embodiment, the sound (sound) emitted from the speaker 13 is transmitted to the vehicle alarm device by disposing the opening from which the sound of the speaker 13 built in the case body 2 is emitted on the lower surface 2c of the case body 2. 1 is output downward. Therefore, since the sound is output downward from the vehicle alarm device 1 mounted on the back surface (rear surface) side of the genuine room mirror 30, the sound proceeds to the driver side and is easy to hear. Note that the position of the opening may be the side surface 2b on the driver's seat side instead of the lower surface 2c as in the present embodiment. In this way, sound is output directly to the driver, so that passengers in the front passenger seat are not disturbed.

  On the other hand, on the rear surface of the housing 4, that is, on the surface of the lid portion 3, almost the entire surface is a rectangular hook-and-loop fastener attachment region 3 a. The hook-and-loop fastener attachment region 3a is set at the center in both the vertical and horizontal directions. This hook-and-loop fastener attachment area 3a is one step lower (recessed) than the surrounding area, making it easy to position when attaching either the male or female hook-and-loop fastener, and mounting the hook-and-loop fastener at an appropriate position. it can. For positioning, instead of lowering in this way, a protrusion may be provided on the outer frame portion that partitions the region 3a (the surface fastener attachment region 3a and the peripheral region are flush with each other). Of course, without providing such a step or the like, it is possible to simply print a line and use it as a guideline when attaching the surface fastener.

  Furthermore, a strap attachment hole 4 a is provided above the rear surface of the housing 4. As shown in FIG. 7, the strap attachment hole 4a is a communication hole opened at a predetermined position on the surface of the housing 4 on the lid 3 side and the upper surface of the housing 4, and a beam portion 4b for attaching the strap is provided. . When a commercially available strap 26 is inserted into the strap attachment hole 4a, the end 26a of the strap 26 is attached to the beam portion 4b, and the tip of the strap 26 is put on the rearview mirror 30, the vehicle alarm device 1 can be prevented from falling. Since it can utilize as, it is preferable. In FIG. 7, the lid 3 is drawn relatively thick, and both ends of the strap attachment hole 4 a are open on the surface and the upper surface of the lid 3. There is no need, and the upper surface 2a of the case body 2 and the surface of the lid 3 may be opened.

  The control unit 18 is a microcomputer including a CPU, a ROM, a RAM, a nonvolatile memory, an I / O, and the like. The various input devices (the microwave receiver 5, the wireless receiver 6, the GPS receiver 7, A predetermined process is executed based on information input from the remote control receiver 16 and the memory card slot 9), and a predetermined alarm / message is output using the output device (lamp 12, speaker 13). The functions of the vehicle alarm device 1 according to the present embodiment are stored on the EEPROM of the control unit 18 as a program executed by the computer included in the control unit 18, and are realized by the computer executing the program in the control unit 18. .

  The vehicle alarm device 1 according to the present embodiment is different from the conventional mirror type vehicle alarm device, and is provided with a display screen for outputting alarm contents as a text image without a mirror portion on the surface. Absent. An alarm or the like is notified by voice using a small built-in speaker. In connection with this, the housing | casing of the alarm device 1 for vehicles can be reduced in size. As an example, the height H can be 50 mm and the width W can be 90 mm.

  When actually mounting the vehicle alarm device 1 in the vehicle compartment, as shown in FIG. 10, one male and female hook-and-loop fasteners 25 a are pasted on the hook-and-loop fastener mounting region 3 a set on the surface of the lid 3. (See (a) in the figure) The other hook-and-loop fastener 25b paired with the hook-and-loop fastener 25a is affixed to a predetermined position on the rear side of the rearview mirror 30 (opposite side of the mirror portion, front side of the vehicle) (see FIG. (See (b)). At this time, the hook-and-loop fastener 25b is affixed at such a position that the infrared light receiving portion 16a is not hidden so as not to be received by the room mirror 30.

  And as shown in the figure (c), it joins so that it may not shift | deviate between male and female double-sided fasteners 25a and 25b, and the alarm device 1 for vehicles is fixed to the back surface of the genuine room mirror 30. FIG. At this time, the vehicle alarm device 1 is mounted so that the power switch 11 and the like are positioned below.

  In this embodiment, since the vehicle alarm device 1 is attached to the back surface of the room mirror 30 using a hook-and-loop fastener, the following operational effects are exhibited. That is, both the male and female hook-and-loop fasteners 25a and 25b each have a predetermined height, and the male and female fasteners have an adhesive force within the height range. Therefore, although the hook-and-loop fastener attachment region 3a of the vehicle alarm device 1 of the present embodiment is a flat surface, even if the rear surface of the room mirror 30 to be attached is configured with a curved surface, the curved surface is absorbed and bonded in the height range. Have power. Further, the hook-and-loop fastener functions as a cushion, can absorb the vibration of the vehicle that occurs during running, idling, etc., and can suppress the shakiness of the housing. Of course, it is more preferable to select a flat part on the back surface of the rearview mirror as the mounting surface.

  As is clear from this figure, the vehicle alarm device 1 of the present embodiment is relatively small, the height H is lower than the height of the standard equipment room mirror 30, and the width W is a standard equipment room mirror. It is even shorter than half of it. Therefore, in a state where the vehicle alarm device 1 is fixed to the room mirror 30, the vehicle alarm device 1 is completely hidden behind the room mirror 30. Therefore, the driver's field of view is not obstructed, so the safety is high, the driver's / passenger's field of view does not enter, the interior of the vehicle is clean, and the interior environment of the original vehicle is unified. Can be maintained.

  Further, since the width W of the vehicle alarm device 1 is set to be equal to or less than half the width of the room mirror 30, the vehicle alarm device 1 is attached to an area on one half of the room mirror 30 as illustrated. It is preferable that the side to be attached is the driver's seat side because the operability is good for the driver. And since the vehicle alarm device 1 of this embodiment is small and light, even if it arrange | positions in the state biased to one side in this way, the room mirror 30 does not tilt.

  Furthermore, since the infrared light receiver 16a is provided on the lower surface 2a of the case main body 2, even if the vehicle alarm device 1 is hidden behind the rear mirror 30, the reaction of the remote control is good. The position of the infrared light receiving unit 16a may be the side surface 2b on the driver's seat side, instead of the lower surface 2c as in the present embodiment. This makes it possible to communicate more reliably when the driver performs a remote control operation.

  Similarly, since the lamp 13 is provided on the lower surface of the case body 2a, it is easy to see. That is, even if the vehicle alarm device 1 is hidden behind the rear-view mirror 30 and cannot directly see the lamp 13, the lamp 13 emits light downward, so that it is lit or not flashing. Can be confirmed. From the viewpoint of the visibility of the lamp 13, the lower surface 2c of the case main body 2 and the lower end of the rearview mirror 30 are substantially aligned with each other, or the vehicle alarm device 1 is attached so as to slightly protrude downward. May be.

  Furthermore, since the power switch 11 is also arranged on the lower surface 2c, it is easy to operate the power source. In particular, the operability can be ensured regardless of whether the vehicle is mounted on either the left handle or the right handle. As described above, the operability is good in both the left and right steering wheels regardless of the power switch 11, and the same is true in the data communication between the infrared light receiving unit 16a of the remote control receiver 16 and the remote control 17 (reaction is good). However, the same applies to the visibility of the lamp 13.

  In the vehicle alarm device 1 of the present embodiment, the memory card slot 9 is disposed on the side surface 2b on the driver's seat side for the right-hand drive vehicle. It becomes easy to insert and remove the memory card 10. Of course, since the memory card 10 is not attached to or detached from the memory card slot 9 during driving, there is not much problem even when it is attached to a left-hand drive vehicle. Further, as a left-hand drive vehicle mode, the memory card slot 9 may be disposed on the side surface opposite to the vehicle alarm device 1 of the present embodiment. Furthermore, if the memory card slot 9 is also arranged so as to open to the lower surface 2c, the same good operability can be obtained in a vehicle with either left or right handle. And even if the opening is facing down, this type of memory card slot has a locking mechanism. When the memory card is pushed in all the way, it is held in that state, and the memory card 10 is held from that state. Since a mechanism is employed in which the lock is released by pushing it back again, problems such as inadvertent dropping of the memory card 10 do not occur.

  In this embodiment, the vehicle alarm device 1 is attached to the rear side of the rearview mirror 30, and the antennas of the microwave, radio, and GPS receivers 5, 6, and 7 are arranged on the front side. Each antenna faces the windshield. In addition, the distance to the windshield is short, and no other obstacle is inserted between the antenna and the windshield. Therefore, high sensitivity reception can be performed for various radio waves coming from the front or above (obliquely upward) toward the vehicle. In particular, windshields with insulated wires used in luxury cars, etc., have a problem that radio waves are difficult to pass through and the receiver's reception sensitivity is reduced. Since no heat insulation wire is provided, each of the antennas faces a portion where the heat insulation wire is not provided, and reception sensitivity does not decrease.

  Furthermore, some room mirrors are called anti-glare mirrors. These anti-glare mirrors cause the headlights of the following vehicles to be reflected on the rear-view mirror when the driver tries to check the rear view by looking at the rear-view mirror when driving at night. It has a function to prevent rearrangement and to secure the rear view firmly. For example, by using levers 32 to change the tilt of the mirror to reflect on a surface with a different reflectivity or a mirror surface called an electrochromic element, the reflectivity is changed by electronic control. There are various types such as what is possible. On the other hand, in the conventional mirror type vehicle alarm device (radar detector), the alarm device itself is provided with a mirror part and is mounted on the mirror part side of the standard room mirror. Therefore, even if it is a room mirror of a glare-proof mirror aspect, the mirror part will be covered with the alarm device for vehicles, and back confirmation is performed using the mirror part with which the mirror type vehicle alarm device is provided. In general, a mirror type vehicle alarm device does not have an anti-glare mirror function. Therefore, there is a demerit that the anti-glare function of the anti-glare mirror of the vehicle cannot be used. However, in this embodiment, the mirror part of the standard room mirror is not covered, and the rear confirmation is performed using the mirror part of the Lou mirror, so when the room mirror has an anti-glare function, Can be used without interfering with its function. Similarly, even when the vehicle mirror has a predetermined function other than the anti-glare function (for example, a back monitor function), the vehicle mirror can be used without hindering its inherent function.

  Furthermore, in this embodiment, since the alarm device 1 for vehicles is affixed and fixed to the room mirror 30, there exists a possibility that it may peel and remove | deviate. Therefore, the fall prevention mechanism is as follows.

  First, the relationship between the force for pulling the power supply direct connection cord 21 (DC plug 22) from the DC jack 9 and the weight of the main body of the vehicle alarm device 1 is set to a weight that does not come out of the DC jack 9 when the main body falls from the room mirror. . Specifically, it is about 80 grams. When a normal DC jack and a DC plug are used, it is preferably 200 grams or less, particularly preferably 100 grams or less. That is, in order to prevent the direct power supply cord 21 from hanging down in the vehicle interior, the cord clip is sandwiched between the cord clips and the cord clips are attached to predetermined positions in the vehicle interior using a double-sided adhesive tape, along the inner surface of each stay. Fix it so that it crawls. In this case, if the hook-and-loop fasteners 25a and 25b are peeled off, or the double-sided tape or the like bonding the hook-and-loop fasteners 25a and 25b is peeled off, the vehicle alarm device 1 is separated from the room mirror 30 and tends to fall. However, since the DC jack 22 is held in the DC jack 9, the vehicle alarm device 1 is hung from the power supply direct connection cord 21. Therefore, the vehicle alarm device 1 is prevented from falling.

  Moreover, it is preferable that the power supply direct connection cord 21 is moved near the ceiling in the passenger compartment. Therefore, when the DC jack 9 is provided on the side surface 3a as in this embodiment, the DC plug 22 may be an L-shaped plug. If it does in this way, it will be easy to guide the power supply direct connection cord 21 to the upper part side of case 4, it will be easy to carry out wiring, and the appearance will be clear. For the same reason, when the DC jack 9 is arranged on the upper surface 2a, the DC plug 22 is preferably an I-shaped plug.

  As another fall prevention mechanism, a commercially available strap 26 is inserted into the strap attachment hole 4a, and the end portion 26a of the strap 26 is attached to the beam portion 4b. (See FIG. 9). As a result, even if the DC plug 22 is disconnected from the DC jack 9 or the power supply direct connection cord 21 is detached from the cord clip or the cord clip itself is peeled off, the vehicle alarm device is securely attached to the room mirror 30 by the stop 26. Since 1 is suspended, it can be prevented from falling.

  Furthermore, in this embodiment, the strap attachment hole is provided and the user attaches the strap separately. However, the present invention is not limited to this, and the fall prevention is made of an endless string like a strap. A member may be attached by screwing or the like, and the fall prevention member may be hooked on the column 31.

  In the vehicle alarm device 1 of the present embodiment, the hook-and-loop fastener attaching region 3a is set at the center in the vertical direction of the lid 3, and the hook-and-loop fastener 25a is attached to the central portion in the vertical direction of the main body. For example, as shown in FIG. That is, the room mirror 30 is often tilted so that the lower side is forward and the upper side is rearward in order to face the driver. Therefore, it is preferable to provide a hook-and-loop fastener attachment portion facing the upper side, since the portion with the upper hook-and-loop fastener and the portion without the lower hook-and-loop fastener fit with the weight of the rear surface of the rearview mirror. In either case, the attaching member is not limited to the hook-and-loop fastener, and may be a double-sided adhesive tape.

  The above-described embodiments and modifications are realized using a single housing, but may be configured using a plurality of cases (housings). For example, as shown in FIG. 12, two cases of a first case 40 and a second case 41 are used. The first case 40 and the second case 41 are arranged on both sides of the rear mirror 30 with the support 31 interposed therebetween. For attachment, an attaching member such as a hook-and-loop fastener can be used in the same manner as described above. In this way, the weight balance can be achieved and the tilting and vibration of the mirror during traveling can be prevented.

  Further, the circuits / parts built in the cases 41 and 40 have a connection cable 42 wired between the cases 40 and 41 for data communication and power supply. Then, the connection cable 42 may be passed over the column 31 of the room mirror 30. With such a configuration, even if one or both of the cases 40 and 41 are peeled off from the room mirror 30, they can be prevented from falling off immediately. In this example, the connection cable 42 is also used as a fall prevention mechanism, but a string or the like for connecting the two may be attached to prevent the fall.

  Moreover, the installation position of the infrared light receiving unit 16 a ′ can be set to the front side of the case body 2. In this case, the infrared rays transmitted from the remote controller 17 are reflected by the windshield and received.

  Further, in each of the above-described embodiments and modifications, the display unit is not provided, but the provision of the display unit is not hindered. In that case, since the vehicular alarm device 1 is stuck and fixed to the rear surface of the room mirror 30, the display unit protrudes above or below the room mirror 30. More preferably, the display unit may have a structure protruding to the mirror surface side of the room mirror 30. If it does in this way, since it will approach the side of viewers, such as a driver, it will become easier to see. Further, when the first case and the second case are divided into a plurality of cases, the basic function other than the display unit is incorporated in the first case, and the display unit is incorporated in the second case. You can also. Then, the second case is disposed so as to be positioned on the upper surface or the lower surface of the first case. The second case preferably has a function of recognizing whether it is located on the upper side or the lower side (up / down direction of itself) by a sensor or a switch, and the display can be reversed upside down according to the direction. . As described above, when the function of the display unit is incorporated in the second case, the first case and the second case are made detachable, and when only the first case is attached, the display is performed in the same manner as in the basic embodiment described above. When the second case is connected to the first case, it can function as a vehicle alarm device for the sign object machine.

  Moreover, about the vehicle which has a display apparatus in a room mirror, you may make it connect the video output of this alarm device for vehicles to the video signal line to the display apparatus. If it does in this way, an alarm can be performed using the display device in the mirror which vehicles have, without installing a new display device.
