Description

  The present invention relates to a drive recorder and an in-vehicle optional component.

  A drive recorder that stores vehicle status information before and after an automobile accident (forward image, vehicle speed, sudden acceleration / deceleration, etc.) provides useful information for verification in the event of an automobile collision. In particular, it is widely used in transportation vehicles such as trucks and business vehicles such as taxis and buses, and is also being installed in general vehicles.

  This drive recorder is capable of storing a front video and a driving data indicating a driver's driving operation (brake operation, turn signal operation, driving route, etc.) for a certain period before and after the occurrence of an accident or sudden braking. It has a configuration. Briefly explaining the configuration for storing video data, the CCD camera always images the vehicle and surroundings from the viewpoint (view) of the driver, and the captured video is stored in a temporary storage memory such as a ring buffer. Remember. The video stored in the temporary storage memory is sequentially updated to the latest one, and the past video data is held for the set time. On the other hand, the drive recorder is equipped with a sensor that detects an impact such as an acceleration sensor or an impact that occurs during sudden braking or sudden steering. If the output value of the sensor exceeds the threshold, the threshold is exceeded (impact detection). The previous video for a certain period is read from the temporary storage memory and stored in a non-volatile memory (such as an SD memory card). After the threshold value is exceeded, the captured image of the CCD camera is directly or temporarily stored in the non-volatile memory. By storing via a storage memory, it has a function to save images and running data for a predetermined time before and after the impact in a nonvolatile memory (SD card).

  When an accident occurs, it is possible to clearly testify the validity of the driver based on the vehicle status information (video etc.) of the own vehicle stored in the non-volatile memory. In addition, when the drive recorder detects a rough and dangerous driving operation such as a sudden handle or a sudden brake, it may give a certain tension to the driver by alerting the driver with a warning sound or the like. it can.

  Since this drive recorder captures and stores a front image of the vehicle, it is usually attached to the windshield of the vehicle. Specifically, as shown in Patent Documents 1 and 2, a mounting member having a mounting surface inclined at a predetermined angle with respect to the main body is provided on the upper surface of a flat rectangular main body in which a CCD camera, a sensor, and the like are incorporated, Adhesive and fixed in place on the windshield using adhesive tape, double-sided adhesive tape, suction cups, etc. provided on the mounting surface.

  Improvements and developments to conventional drive recorders ensure that video is recorded at the time of an accident, and that as much information as possible can be collected and recorded accurately. The main function of the drive recorder is to improve the functions of the drive recorder. And this kind of drive recorder may have its existence value when an accident actually occurs, and it is installed in a vehicle that drives relatively frequently like a taxi or other commercial vehicles, and it is usually not driven much The fact is that it is not so often installed in ordinary driver's vehicles.

  On the other hand, once an accident has occurred, the presence of a drive recorder makes it possible to objectively confirm the situation at the time of the accident, which is also beneficial for the above general driver. Therefore, there is a problem that drive recorders are to be spread and installed in as many vehicles as possible.

  If you install the drive recorder and optional parts for vehicles such as radar detectors after purchasing the vehicle, it is necessary to fix it to the vehicle for each device, and it is necessary to wire the power cable etc. for each device. There is a problem that installation takes time and the aesthetics in the vehicle may be damaged.

  In order to solve the above-described problems, the present invention provides (1) a drive recorder main body (having functions as a drive recorder such as a camera, recording means, and control unit) and a vehicle-mounted device connected to the drive recorder main body. Optional components. By connecting the optional parts for vehicles, for example, during normal operation and other situations, the functions of the optional parts for automobiles operate. Can be experienced. Once an accident occurs, necessary information can be recorded by the original drive recorder function of the drive recorder body, and appropriate processing can be performed based on objective information at the time of the accident.

  (2) having a mounting bracket having a ring part rotatably mounted on the drive recorder main body and an attachment member connected to the outside of the ring part, and the ring part includes the drive recorder main body and the drive recorder main body; It is good to fix by being pinched | interposed between in-vehicle optional components.

  In the embodiment, the ring portion is mounted on the outer peripheral surface of the drive recorder main body and arranged so as to be exposed to the outside. However, the present invention is not limited to this, and all or part of the ring portion is the drive recorder main body. You may take the structure accommodated in the inside. In addition, coupled with connecting the mounting member to the outside of the ring portion, the ring portion is mounted on the outer peripheral surface of the drive recorder main body and exposed to the outside. It is preferable because it can be rotated while holding the outer peripheral surface and the relative angular position between the ring portion and the drive recorder main body can be easily adjusted. Further, in this embodiment, the rotatable angle is 360 degrees, but it may be a predetermined angle range. Furthermore, if the overall shape of the drive recorder body is based on a cylindrical shape as in the embodiment, the design is uniform with the ring part, but it is not necessary to have a cylindrical shape. The shape can be taken. Furthermore, if the mounting position of the ring portion is attached to one end portion side of the drive recorder main body as in the embodiment, the angle can be easily adjusted and fixed, but a layout installed from the center may be adopted. .

  In the present invention, since the ring portion is rotatably attached to the drive recorder main body, the ring recorder and the drive recorder main body are relatively rotated before being fixed to the drive recorder main body, so that the drive recorder main body and the ring portion are rotated. The relative angular position of (bracket) can be set to a desired state. And by fixing in that state, it is possible to change / adjust the relative angular position between the mounting member fixed to the windshield or the like by bonding or the like and the drive recorder main body, and different while adopting a single unit configuration It can be mounted on a vehicle (with different windshield angles). Furthermore, in the present invention, such fixing can be performed by connecting the on-vehicle optional component to the drive recorder main body, and it is preferable because it can be performed by a simple operation of pinching.

  (3) A mounting bracket including a ring portion rotatably mounted on the drive recorder main body, and an attachment member connected to the outside of the ring portion; the ring portion and the in-vehicle optional component are connected to the drive recorder; It is good to provide the fixing member fixed to a main body. The fixing member corresponds to the nut member 40 in the embodiment. It is preferable that the fixing member is fastened to the drive recorder main body using a screw mechanism like a nut member because it can be realized with a simple configuration, but it is fixed using a spring or fixed by an appropriate locking mechanism. You may do it. Furthermore, it is not limited to the one that sandwiches and fixes the ring portion between the fixing member and the drive recorder main body as in the embodiment, for example, using a screw (bolt) that extends inward from the outside of the ring portion, Various mechanisms such as fixing by screwing can be employed. Further, in the embodiment, the fixing member is connected to the drive recorder main body in a state in which the target object detection unit that is an in-vehicle optional component is housed in the nut member that is the fixing member, and the ring portion is sandwiched and fixed. The in-vehicle option parts are also fixed so as to be sandwiched together, but the present invention is not limited to this, and a configuration in which the in-vehicle option parts are connected to the outside of the fixing member may be adopted. Further, the fixing member and the in-vehicle optional component may be integrated in advance.

  (4) The said fixing member shall clamp the said ring part between the said main bodies, and shall fix the ring part. This is preferable because it can be easily switched between fixing (positioning by stopping rotation) and releasing (rotating and adjusting the angle) of the ring portion. In particular, if the pinching force can be adjusted, temporary fixing can be performed in a lightly tightened state, and the position adjustment operation can be performed more easily. In particular, when connected by a screw mechanism as in the embodiment, the interval between the main body and the fixing member can be narrowed by fastening the screw, and the mounting bracket is firmly fixed with a simple configuration. be able to. In this embodiment, the external thread is formed on the main body side and the internal thread is formed on the nut portion side that is the fixing member. However, the reverse arrangement may be used. .

  In each of the above inventions (2) to (4), irregularities are formed on at least a part of the opposing surface of the drive recorder main body and the ring portion, and the ring portion is formed by the fixing member or the on-vehicle optional component. When the is fixed, it is preferable that the irregularities coincide with each other. Although the rotation of the mounting bracket can be suppressed to some extent by the tightening force between the fixing member and the drive recorder body, the rotation can be more reliably suppressed by providing irregularities at appropriate positions. Moreover, although unevenness was continuously formed over the perimeter in embodiment, you may arrange | position discretely. However, it is preferable to form them continuously because the rotation angle can be finely adjusted.

  (5) The in-vehicle optional component may be attached to the left side or the right side of the drive recorder main body in the installed state in the vehicle. When such a configuration is adopted, in particular, when the drive recorder is attached to the windshield, the in-vehicle optional parts do not get in the way, which is preferable. In other words, the upper direction of the drive recorder main body has no space, and the lower direction obstructs the field of view.

  (6) When connecting the in-vehicle optional component to the drive recorder main body, it is preferable that the in-vehicle optional component is electrically connected by a connector provided on both. In this way, some functions can be incorporated into the other device (drive recorder main body / in-vehicle optional component) or shared, increasing the flexibility of the layout of the mounted components and increasing efficiency. As a result, the overall size can be reduced. The number of connectors is arbitrary, and may be one or plural.

  (7) At least one of the connector provided in the in-vehicle option part and the connector provided in the drive recorder main body may have a cable. In this way, there is room for rotation between the in-vehicle optional parts and the drive recorder body by the length of the cable, and a space is secured between the two even during installation (at least for the cable length, there is no cable. This is preferable because the connector connection work becomes easy.

  (8) The connector provided in the in-vehicle option component and the connector provided in the drive recorder main body are a male connector and a female connector fixedly installed on opposing surfaces of the in-vehicle option component and the drive recorder main body, respectively. It is preferable that the relative angular position of the in-vehicle optional component and the drive recorder main body is determined by connecting both the connectors. In this case, the rotation angle position of each other is defined by connecting the in-vehicle optional component to the drive recorder main body, so that the user does not need a special positioning work, and the radio wave is included in the in-vehicle optional component. Even if the installation direction of the receiving unit or the photographing device is important, it can be set to an appropriate position and posture.

  (9) The connector has at least one of a power supply line and a signal line. In the embodiment, both the power supply line and the signal line are included.

  (10) The connector may include a signal line, and may have a function of sending an event signal from the in-vehicle optional component to the drive recorder main body and performing event processing together with input information on the drive recorder main body. In the embodiment, this event signal is a reception signal of various radio waves in the target object detection unit, or video data captured from the additional main body 10 '. In the embodiment, the event processing is performed by the control unit on the main body 10 side to determine the presence / absence of the target object to be notified based on the received radio wave, and if it exists, notifies / warns the presence of the target object, For example, a stereo camera image may be generated and recorded.

  (11) It is preferable that the connector includes a signal line and has a function of setting the in-vehicle optional component by a function setting signal output from the drive recorder main body. In this way, it is not necessary to provide a setting switch or the like on the in-vehicle optional component side, and the size can be reduced.

  (12) An external power supply port is provided on a side surface of the in-vehicle option component, and the in-vehicle option component and the electronic device in the drive recorder main body can be operated by an external power source supplied from the power supply port. It is good to do. In this case, the charging / discharging circuit is mounted together with the rechargeable battery (secondary battery), and when there is no supply from an external power source, it is not hindered to have a function of operating by discharging from the secondary battery. In particular, when the in-vehicle optional component is not supplied with an external power source when the vehicle is stopped, like a security device, it is preferable to provide a secondary battery. Of course, when there is no supply of external power, it is possible to supply from the primary battery, so the secondary battery is not necessarily essential. Further, the installation position of the secondary battery may be anywhere on either the drive recorder main body, the on-vehicle optional component or both.

  (13) The drive recorder main body includes a card slot for mounting a memory card for storing recording data, and an outlet of the card slot is set on an end surface opposite to the mounting bracket. Good. This makes it easy to attach and remove a memory card such as an SD card to / from the card slot.

  (14) An operation switch may be disposed on the front surface of the drive recorder main body, and a volume operation unit for adjusting a volume of a speaker built in the drive recorder main body may be disposed on a side surface of the drive recorder main body or the in-vehicle optional component. . In this way, since a frequently used switch comes to the front, it is easy to operate.

  (15) The in-vehicle optional component may include a radio wave receiving unit, and the receiving surface of the antenna of the radio wave receiving unit and the operation direction of the volume operation unit may be arranged in parallel. This is preferable because the direction of the radio wave receiving unit can be estimated from the operation direction of the volume operation unit, and the radio wave receiving unit can be easily adjusted to an appropriate direction and posture.

  (16) The GPS antenna built in the drive recorder main body may be disposed obliquely upward. “Arranged obliquely upward” means that the GPS antenna surface is directed obliquely upward with respect to the basic posture of the main body (standard posture when the vehicle-mounted device is installed in the vehicle). In this way, for example, even if the orientation of the main body (for example, the orientation of the camera when the camera is incorporated) is downward, the GPS antenna can obtain good GPS reception sensitivity.

  (17) The in-vehicle optional component includes a radio wave receiver, and a relative angular position between the two is set by a positioning mechanism provided between the in-vehicle optional component and the drive recorder body. It is preferable that the direction of the antenna of the radio wave receiving unit is specified. This is preferable because the user can automatically set an appropriate position without being aware of the direction of the radio wave receiving unit.

  (18) The installation surface of the switch formed on the surface of the drive recorder body may be a flat surface so that the field of view of the camera faces the opposite side of the installation surface. (19) In this case, it is more preferable that the flat surface and the field of view are set to be orthogonal to each other. When a camera is provided and the front is photographed like a drive recorder, it is difficult to directly confirm the direction of the camera facing the front from the inside of the vehicle. However, the installation surface of the switch (which faces the inside of the vehicle because it is operated by the driver, etc.) is made flat and the camera's field of view is directed to the opposite side of the flat surface. Since the orientation of the camera with respect to (surface) is known, the orientation of the camera can be estimated from the orientation of the installation surface. At this time, if the orientation of the camera is orthogonal to the flat surface as in the invention of (19), for example, if the installation surface is made parallel to the vertical direction, the camera will face the horizontal direction. The direction can be estimated more easily. However, even if they are not necessarily orthogonal, there is no problem because the direction of the camera relative to the installation surface can be estimated.

(20) It is preferable that other in-vehicle option parts can be connected to the non-connection side of the in-vehicle option parts with the drive recorder main body. (21) The on-vehicle optional component may be a target detection unit that detects a target existing in the surroundings, or (22) an additional drive recorder main body, which is a camera built in these two drive recorder main bodies. Based on this, various functions can be applied, such as providing a recording function as a stereo camera, (23) any of an indoor photographing device, a security device, and a snoozing prevention device.

  In addition, since the inclination of the windshield differs depending on the type of vehicle, there is a problem that the vehicle cannot be mounted depending on the vehicle if the mounting structure is fixed. In the invention disclosed in Patent Document 2, on the premise that the mounting posture of the main body of the drive recorder is changed, a technique for detecting the posture of the main body and correcting the image taken by the CCD camera is proposed. . And although a plurality of types of mounting members (mounting jigs) are prepared according to the inclination of the windshield, the drive recorder can be mounted using a mounting jig suitable for the vehicle to be mounted. When a plurality of types of attachment members are sold as a set, an attachment jig unnecessary for the user is purchased, which is not preferable. Therefore, according to the inventions such as (2) and (3), in order to rotatably mount the ring portion of the mounting bracket, the relative rotational angle relationship between the mounting member of the mounting bracket and the main body is changed. It can handle different types of vehicles with a single unit configuration.

  (24) The in-vehicle optional component of the present invention is an in-vehicle optional component that can be connected to the drive recorder main body for constituting the drive recorder described in any one of (1) to (23) above. is there.

  Since the in-vehicle optional parts are connected to the drive recorder main body, they are referred to as “in-vehicle optional parts” in the sense of the option for the drive recorder main body, but in the present invention, without being bound by the name, All devices that meet the requirements of each claim connected to the drive recorder body are included.

  In the present invention, in-vehicle optional parts can often provide various services in many cases, and can spread a useful drive recorder when an accident occurs.

  Hereinafter, a preferred embodiment of a drive recorder according to the present invention will be described with reference to the accompanying drawings. First, the drive recorder according to the present embodiment includes a cylindrical main body 10. The mounting bracket 30 is attached to one end of the main body 10 in the axial direction, and the mounting bracket 30 is a nut serving as a fixing member. The structure fixed with the member 40 is taken.

  The main body 10 is configured by abutting a first case 11 and a second case 12 that are divided into two (half) at the front and rear. As shown in FIGS. 2 to 5 and the like, the one end portions 11a and 12a of the first case 11 and the second case 12 are formed so that the outer dimensions are slightly smaller, and the one end portions 11a and 12a and the shaft of the main body are formed. A step is formed between the central portion in the direction. A triangular wave (sawtooth) tooth portion 17 is formed on the wall surface where the step is generated. Furthermore, a male screw 18 is formed on the outer peripheral surface of the front end side of the one end portions 11a, 12a of the first case 11 and the second case 12.

  The mounting bracket 30 is erected on the ring portion 31 having an inner diameter that substantially matches (slightly larger) the outer diameter of the one end portions 11 a and 12 a of the first case 11 and the second case 12, and the outer peripheral surface of the ring portion 31. And a mounting plate 33 provided at the tip of the connecting column part 32. As shown in FIG. 6, the mounting plate 33 is disposed obliquely at a predetermined angle with respect to the diameter direction of the ring portion 31.

  Further, a tooth portion 34 is formed on one surface of the ring portion 31 (a surface facing the main body 10) over the entire circumference thereof. The teeth 34 are set to have the same size and shape so as to coincide with the teeth 17 formed on the main body 10. Further, as shown in FIG. 7, the width D of the ring portion 31 is substantially the same as the width D1 of the flat portion (the unformed region of the male screw 18) of the one end portions 11 a and 12 a of the first case 11 and the second case 12. I have to. Of course, it may be set wider than D1 (D1 <D), but in that case, it is set shorter than the width D2 up to the tip including the male screw 18 (D1 <D <D2).

  A nut member 40 is attached to the male screw 18. The nut member 40 has a cylindrical shape with a predetermined length opened at both ends, and a female screw that matches the male screw 18 is formed on an inner peripheral surface 41 at one end thereof. As a result, when the ring portion 31 is attached to the one end portions 11a and 12a of the first case 11 and the second case 12, the ring portion 31 has one end of the first case 11 and the second case 12 with its central axis as the rotation center. It can be rotated forward and backward relative to the portions 11a and 12a. And rotation is suppressed by meshing | engaging the tooth part 17 provided in the main body 10, and the tooth part 34 provided in the ring part 31. FIG.

  On the other hand, in the state where the ring portion 31 is mounted on the one end portions 11 a and 12 a of the first case 11 and the second case 12 as described above, the male screw 18 projects outward from the ring portion 31. Therefore, the nut member 40 is attached to the protruding male screw 18. And as shown in FIG. 8 etc., the space | interval to the level | step-difference part which formed the tooth | gear part 17 of the nut member 40 and the main body 10 by fastening | tightening the internal thread of the nut member 40 and the external thread 18 of the main body 10 firmly. The ring portion 31 can be sandwiched between the main body 10 and the nut member 40 with a predetermined force. When the teeth 17 and 34 are engaged with each other in this manner, the rotation of the ring portion 31 and thus the mounting bracket 30 is suppressed, and when the nut member 40 is loosened, the rotation is allowed. Therefore, the relative angular positional relationship between the main body 10 and the mounting bracket 30 can be set (adjusted) to an arbitrary position and fixed at that position. That is, when a plane (direction) parallel to the joint surface of the first case 11 and the second case 12 is a basic vertical direction of the main body 10, an angle formed by the vertical direction and the mounting plate 33 of the mounting bracket 30 is defined. Can be changed.

  A double-sided tape (not shown) or other adhesive member is attached to the upper surface of the mounting plate 33, and is adhered and fixed to the windshield of the vehicle using the double-sided tape. Therefore, the drive recorder of this embodiment can be adjusted according to the angles (25 to 75 degrees) of various windshields. That is, although the mounting plate 33 is parallel to the angle of the windshield, as described above, the relative angle of the main body 10 with respect to the mounting plate 33 (mounting bracket 30) can be adjusted, so the angle of the mounting plate 33 (windshield) Regardless of whether the main body 10 is in the basic vertical direction, for example, it can be parallel to a vertical plane (with respect to the ground). Of course, the angle formed between the basic vertical direction of the main body 10 and the vertical plane with respect to the ground can be set to an appropriate angle. Therefore, it can be mounted on different types of vehicles with one drive recorder.

  Further, by firmly fastening the nut member 40, the tooth portion 17 of the main body 10 and the tooth portion 34 of the mounting bracket 30 are firmly meshed with each other and their rotation is reliably prevented. Even if an impact is applied, the orientation and orientation of the main body 10 can be maintained in the basic orientation when the drive recorder is attached to the windshield (unless the mounting plate 33 is peeled off from the windshield) and can be firmly fixed. it can.

  Furthermore, although not shown in the drawings, it is preferable to adopt a configuration in which a packing made of an elastic body such as rubber is arranged inside the nut member 40 (on the main body 10 side). In this case, the inner diameter of the packing is preferably set to be approximately the same as or slightly wider than the outer diameter of the male screw 18 of the main body 10, and the outer diameter of the packing is preferably set to be slightly smaller than the outer diameter of the ring portion 31. The thickness of the packing 50 is made uniform over the entire circumference. In the present embodiment, the width D of the ring portion 31 is substantially the same as the width D1 of the flat portion (the unformed region of the male screw 18) of the one end portions 11a and 12a of the first case 11 and the second case 12. In the state where the ring part 31 is mounted on the one end part 11a, 12a, the tip of the flat part of the one end part 11a, 12a and the end face of the ring part 31 on the nut member 40 side are substantially flush with each other. One surface of the packing can contact the main body 10 and the ring portion 31 beyond the male screw 18, and the other surface of the packing is in contact with the inner surface of the nut member 40.

  When the width D of the ring portion and the lengths D1 and D2 of the respective end portions 11a and 12a are set so as to satisfy D1 <D <D2, the packing has a uniform ring shape (donut shape) It is good to provide the annular convex part which fits in the level | step-difference part between D * D1 with respect to a ring part.

  In addition to the effect of tightening the ring part by narrowing the interval between the fixing member and the main body by additionally arranging the packing in this way and using the elastic force of the packing, the tightening force is improved by the elastic force of the packing Can do. Therefore, for example, the distance between the fixing member and the main body is set to be slightly wider than the width of the ring (the distance in this case is changed as appropriate depending on other factors such as the thickness of the packing), and the elastic force of the packing is set. If the ring part is fixed by use, temporary fixing can be performed. By exhibiting the temporary fixing effect in this way, for example, when mounting in a vehicle, the main body must always be supported by hand if there is no packing, but if there is packing, the hand can be released. And when adjusting the angle etc., it is difficult to check the angle by supporting it with the hand with the ring part pressed against the body side, but it is supported by hand because it is temporarily fixed with packing Even if not, it is possible to easily confirm whether or not the angle may be fixed in a state where the angle is temporarily fixed. Therefore, the excellent effect of facilitating installation and adjustment even in a narrow space inside the vehicle is exhibited.

  Furthermore, when a rubber material is used as the packing, in addition to the temporary fixing effect described above, the vibration preventing effect and the anti-skid effect are also exhibited, so that the nut member 40 can be prevented from loosening due to vibration, and only when the in-vehicle device is attached. It is more preferable because it exhibits an excellent effect on stability during use. In other words, unnecessary recording using vibration as a trigger as a drive recorder can be prevented, and an accident video can be recorded more reliably at the time of impact. Of course, this packing is not necessarily provided.

  Furthermore, in this embodiment, the target object detection unit 50 is disposed in the cylindrical nut member 40. The target detection unit 50 receives various radio waves emitted from the target to be detected, notifies a predetermined alarm according to the contents of the received radio waves, acquires the current position, and acquires the current position. When there is alarm / information to be notified in the surrounding area, notification according to the type of the information is performed.

  As shown in FIGS. 9 and 10, the target object detection unit 50 is configured by incorporating predetermined parts into a cylindrical case 51. The outer diameter R <b> 1 of the case 51 is set to be approximately equal to the inner diameter of the nut member 40 or small by an appropriate size, and can be stored inside the nut member 40. In a state where the target object detection unit 50 is housed in the nut member 40, the nut member 40 and the target object detection unit 50 are arranged so that the central axes thereof are substantially coincident with each other and are relatively around the central axis. It can be rotated. That is, even if the target object detection unit 50 does not rotate and maintains its position, the nut member 40 can rotate.

  The other end portion of the nut member 40 (the front end side not connected to the male screw 18 of the main body 10) is provided with a flange portion 42 that protrudes toward the center side. An inner diameter R2 of the flange 42 is set to be smaller than an outer diameter R1 of the case 51 of the target object detection unit 50. Accordingly, as shown in FIG. 10 and the like, in a state where the target object detection unit 50 is housed in the nut member 40, the front end surface 51a of the case 51 is exposed to the outside from the other end portion of the nut member 40. The peripheral edge portion of the distal end surface 51a contacts the flange portion 42 and is prevented from moving further forward (in the direction protruding from the nut member 40). Therefore, the target object detection unit 50 housed in the nut member 40 is prevented from being detached from the opening at the other end of the nut member 40.

  Therefore, when the nut member 40 is fastened to the male screw 18 of the main body 10, the target detection unit 50 in the nut member 40 is kept in the state housed therein. As described above, in the present embodiment, the nut member 40 and the target object detection unit 50 are rotatable relative to each other. Therefore, when the nut member 40 is rotated forward and backward for fastening / releasing, the target is detected. The operation can be performed regardless of whether the object detection unit 50 is in a rotatable state.

  Further, on the front end surface 51a of the case 51 of the target object detection unit 50, there are provided objects to be operated by the user such as a volume dial 53 and a DC jack 55. As described above, the other end portion of the nut member 40 is opened and the front end surface 51a of the case 51 is exposed to the outside, so that the volume dial 43 and the like are also exposed. By adopting such a configuration, it is possible to install a user's operation target in a limited space of this apparatus, and as a result of attracting the user's attention during operation, it is easy to check whether the nut member 40 is loose. Can be.

  In the present embodiment, the nut member 40 and the target object detection unit 50 are configured as separate members, but they are integrally formed, that is, the nut member is coaxially formed on the other end surface 51b side of the case 51 of the target object detection unit 50. The structure which connected to freely rotate is taken. Thereby, the target object detection unit 50 can be attached to or detached from the main body 10 by rotating the nut member part forward and backward.

  Next, an arrangement structure of each component mounted in the main body 10 and an externally exposed structure of the component will be described. As shown in FIG. 11, a CCD camera 13, a GPS antenna 14, a first connector 15, a power supply circuit, and the like are mounted on the first case 11 side. A circular opening 11b is formed at a predetermined position of the first case 11 (a position facing the CCD camera 13), and the CCD camera 13 is exposed to the outside from the opening 11b.

  The GPS antenna 14 is disposed at a predetermined angle with respect to the vertical direction of the main body 10 (surface (direction) parallel to the joint surface of the first case 11 and the second case 12), and is directed obliquely upward. (See FIG. 12 (a), etc.). Thereby, for example, even when the field of view of the CCD camera 13 is set to face obliquely downward when mounted on a track or the like, good GPS reception sensitivity can be obtained.

  Furthermore, the first connector 15 is arranged in parallel with the axial direction of the main body 10 and protrudes outward from one end side of the main body 10. That is, the window hole 11d is formed at a predetermined position on the end surface (side surface orthogonal to the axial direction) of the one end portion 11a of the first case 11, and the first connector 15 is exposed to the outside through the window hole 11d (front end). Project). The first connector 15 is connected to the target detection unit 50, and the circuit in the main body 10 and the circuit in the target detection unit 50 are electrically connected.

  Further, as shown in FIG. 11B and the like, a locking claw 12c is provided at a predetermined position on the joint surface of the second case 12. On the joint surface of the first case 11, a recess for locking is formed at a position corresponding to the locking claw 12c. When the first and second cases 11 and 12 are brought into contact with each other, the locking claw 12c And the concave portion mesh with each other, positioning and preventing displacement (especially axial movement).

  On the other hand, as shown in FIGS. 3 and 5, a man-machine interface such as a switch unit 20, a display unit 21, and an SD card slot 22 and a control circuit are mounted on the second case 12 side. The control circuit is a circuit for realizing the basic function of the drive recorder, and stores the video imaged by the CCD camera 13 or based on a detection signal from an impact detection sensor such as an acceleration sensor (not shown) based on the detection signal described above. Data such as captured images is stored in a nonvolatile memory. Although not shown, an output device such as a speaker is also mounted. From the speaker, for example, an operation sound in the switch unit 20 and various messages (guide, warning, etc.) are notified. In addition, on the second case 12 side, an electronic component / electronic circuit for realizing a function of an acceleration sensor or other drive recorder for detecting a collision or the like is incorporated.

  Furthermore, as shown in FIG. 12B, the first case 11 and the second case 12 have flat surfaces 11e and 12e whose surfaces opposite to the joint surfaces are parallel to the joint surfaces. Therefore, both the flat surfaces 11e and 12e are set in parallel. The CCD camera 13 is exposed to the outside from the flat surface 11e of the first case 11 (the circular opening 11b is formed on the flat surface 11e), and the field of view of the CCD camera 13 is a flat surface. It is set to be in a direction orthogonal to 11e.

  On the other hand, the switch unit 20 and the display unit 21 are arranged on the flat surface 12 e of the second case 12. And when attaching a drive recorder to a windshield, it installs so that the 1st case 11 (CCD camera 13) may face the front of a vehicle, and the 2nd case 12 may face the inside of a vehicle. Therefore, it is difficult for a user such as a driver in the vehicle to directly check the orientation of the CCD camera 13. However, in this embodiment, since the flat surface 11e of the first case 11 and the flat surface 12e of the second case 12 are set to be parallel, the flat surface 12e of the second case 12 facing the vehicle interior. Is the same as the orientation of the flat surface 11e of the first case 11 and then the orientation of the CCD camera 13, so the orientation of the CCD camera 13 is estimated by looking at the orientation of the switch unit 20 and the display unit 21 (flat surface 12e). Therefore, the orientation of the CCD camera 13 can be easily adjusted.

  Furthermore, the SD card slot 22 is disposed on the side surface opposite to the one end 12a of the second case 12 (see FIG. 11 and the like). As described above, among the man-machine interfaces, those that are frequently used such as the switch unit 20 are arranged on the front surface, and those that are not frequently used such as the volume dial 23 and the SD card slot 22 are arranged on the side surface. , Operability is improved. Furthermore, since the SD card slot 22 is arranged on the side surface, there is no front crow or roof in the insertion / removal direction of the SD card 60, and the SD card slot 22 does not depend on the inclination angle of the windshield to which the drive recorder is mounted or the direction of the drive recorder. The card 60 can be easily attached and detached. In addition, since the SD card slot 22 is arranged on the side surface opposite to the mounting bracket 30, it is easier to attach and remove the SD card 60 to and from the SD card slot 22.

  Furthermore, in the structure of the present embodiment, when viewed from the driver, the CCD camera 13 faces the front of the vehicle and the second case 12 is positioned on the driver side, so the SD card slot 22 is positioned on the right side. The mounting bracket 30 (volume dial 53, DC jack 55) is located on the left side (see FIG. 3). The main body 10 (one end portion 11a, 12a) and the mounting bracket 30 (ring portion 31) can be rotated relatively 360 degrees by loosening the nut member 40. Therefore, from the state shown in FIG. 1 and the like, when the main body 10 is rotated 180 degrees to reverse the top and bottom, when the drive recorder is attached to the windshield, the SD card slot 22 The mounting bracket 30 (volume dial 53, DC jack 55) is positioned on the right side. Therefore, it can be installed by being reversed left and right, and it can correspond to either the right handle or the left handle. Furthermore, it is also possible to easily attach the mounting bracket 30 to a plurality of vehicles and use one main body by replacing it with the plurality of vehicles.

  The target object detection unit 50 as an optional part is connected to the first connector 15 and linked to the circuit in the main body 10 as shown in FIGS. That is, although not shown, a through hole is provided at a predetermined position (a position facing the first connector 15) of the other end surface 51b of the case 51, and the tip of the first connector 15 is connected to the case 51 via the through hole. And is linked to a receiving connector portion provided inside the case 51. A second connector 52 is provided on the target detection unit 50 side, and the second connector 52 is connected to the main body 10. In the present embodiment, the first and second connectors 15 and 52 are used to link the circuit in the main body 10 and the circuit in the target object detection unit 50. However, the number of connectors is arbitrary and installed. The position to perform is also arbitrary.

  Moreover, in this embodiment, the 1st connector 15 provided in the main body 10 is united with the main body, and when the main body 10 is fixed, the first connector 15 is configured to keep its position. Similarly, the second connector 52 provided in the case 51 of the target object detection unit 50 is also fixedly installed to the case 51. Therefore, the main body 10 and the target object detection unit 50 are integrated by linking the first connector 15 and the second connector 52 to the corresponding counterparts, so that there are two connecting portions. Both of the target object detection units 50 are restrained from rotating and moving relative to each other, and both rotate integrally around the central axis of the main body 10. In particular, when the tip of the connector (the part to be connected) is made of a relatively rigid material such as a pin and is directly connected to the other female connector, the connection is more integrated and the relative rotational movement is achieved. Is reliably deterred. Even if the main body 10 and the target object detection unit 50 are integrated with each other, the nut member 40 can be rotated and moved relative to the target object detection unit 50. The male screw 18 can be tightened or released.

  As described above, if the main body 10 and the target object detection unit 50 do not rotate relatively (the rotation angle is narrow), the rotational angle position of the target object detection unit 50 relative to the main body 10 is constant. Can be. As will be described later, since the target object detection unit 50 includes a radio wave receiving unit, the radio wave receiving unit has an appropriate orientation in order to perform radio wave reception from a predetermined direction such as in front of the vehicle or above the vehicle with high sensitivity. However, it is possible to set an appropriate angular position without adjusting the positioning of the user.

  As shown in FIGS. 14 and 15, the target detection unit 50 includes, in a case 51, a microwave receiving antenna 56 and a receiving circuit unit 57 for receiving a microwave serving as a radio wave receiving unit, a volume dial 53, a DC A jack 55 is provided. Moreover, you may incorporate the radio | wireless receiving antenna unit for receiving the radio | wireless of a predetermined frequency.

  As described above, the DC jack 55 is arranged parallel to the axial direction of the case 51 and is configured to be exposed to the outside from the one end side of the case 51. That is, a window hole 51c is formed at a predetermined position on the front end surface 51a of the case 51, and the DC jack 55 is exposed to the outside through the window hole 51c. By attaching a DC plug (not shown) attached to one end of a power cable connected to the cigar socket, for example, the drive recorder of this embodiment can supply power from the vehicle battery. And Thus, since the power cable is pulled out from the side of the drive recorder (target detection unit 50), the power cable can be hidden in the rear view mirror by attaching the drive recorder to the side or near the rear view mirror. It can be made beautiful.

  Similarly, the volume dial 53 is disposed on one end (the front end surface 51a of the case 51) side of the target object detection unit 50, and a part of the volume dial 53 is exposed to the outside through a vertical slit 51f provided on the front end surface 51. It protrudes and can be rotated. The volume dial 53 provided in the target object detection unit 50 adjusts the output level of the speaker mounted in the main body 10, and information based on the operation on the volume dial 53 via the second connector 52 or the like is provided. It is sent to the inside of the main body 10.

  The electric power supplied from the DC jack 55 is used to supply power to the device in the target detection unit 50 and is transmitted to the main body 10 via the second connector 52, so that a circuit in the main body 10 is provided. It is also used for power supply. In addition, when a rechargeable secondary battery is mounted in the main body 10, the secondary battery is charged by the power supplied via the second connector 52 by the charge / discharge power supply circuit, During the period when the power supply is cut off, it is preferable to supply power to the circuit in the main body 10 by discharging from the secondary battery. In this case, the power supply to the circuit in the target object detection unit 50 may be performed using the discharge from the secondary battery. This is to prevent the target detection unit 50 from being enlarged and the nut member 40 from being enlarged when a power supply circuit including a secondary battery is mounted in the target detection unit 50.

  Further, the target object detection unit 50 is equipped with a radio wave reception function that is not necessary for the function of the drive recorder and is not mounted in the main body 10, and judges whether or not an alarm is necessary based on the acquired information. A control unit that performs control for issuing an alarm when necessary, an output unit that actually performs an alarm to the outside, and the like that are mounted on the main body 10 may be combined. In this way, it is possible to reduce the size of the target object detection unit 50 and the drive recorder as a whole.

  Specifically, the control unit (MPU) mounted in the main body 10 has a target unit detection / notification function in addition to the original function of the drive recorder. In addition, information (position information, type, etc.) about the target is also stored in storage means (EEPROM, SD card 60 mounted in the SD card slot 22) in the main body 10. The control unit accesses the storage means based on the current position detected by the GPS antenna 14 in the main body 10 and determines whether or not there is a target to be detected around the current position. Raise an alarm. In the case of the present embodiment, the type and direction of the target, the remaining distance, and the like are notified by voice from the speaker, or a message is output to the display unit 21 with characters or marks. Further, when a desired microwave is received by the microwave receiving antenna 56 mounted in the target detection unit 50, an alarm indicating that the microwave has been received is issued. In addition, when the radio reception antenna unit receives radio of a predetermined frequency, an alarm to that effect is given. The predetermined frequency includes, for example, a frequency of radio waves used for an emergency vehicle to notify the position of the host vehicle in a car locator system, a frequency used for emergency radio, and the like.

  In the above-described embodiment, the first and second connectors 15 and 52 are directly connected to the connectors (not shown) provided separately on the other side, but one of the first connector 15 and the second connector 52 or Both may be provided with cables. In that case, when the connector is connected from the margin of the cable length, the work can be performed with a slight gap between the main body 10 and the target object detection unit 50, so that the connector connection work can be easily performed. In this case, a positioning mechanism between the main body 10 and the target object detection unit 50 may be separately provided as necessary. That is, for example, a projection is provided on one or both of the other end surface 51b of the target object detection unit 50 and the front end surface of the main body 10 facing the other end surface 51b, and a recess is provided at a position facing the projection, so that the above connector connection Then, positioning can be performed by fitting the protrusion and the recess. In addition, a part of the substrate mounted in the target object detection unit 50 is protruded to the outside from the other end surface 51b of the case 51, and the protruding portion is inserted into a rear portion provided at a predetermined position on the main body 10 side. You may make it position. In particular, since the substrate on which the microwave receiving circuit unit 57 is mounted is parallel to the microwave receiving antenna 56, the position (orientation) of the substrate is directly directed to the microwave receiving antenna 56. This is preferable because the direction of the part can be adjusted and set directly.

  Moreover, the structure which connects the 1st connector 15 and the 2nd connector (The main body 10 and the target object detection unit 50 are linked by one connector) can also be taken. In this case, for example, by providing a cable to the second connector 52, connection is possible even in the state of the present embodiment in which the drawing position of the second connector 52 is eccentric. Of course, for example, the drawing position (installation position) of the second connector may be set to a position facing the first connector 15 in the vicinity of the center of the other end surface 51b, and both may be directly connected.

  Further, since the target object detection unit 50 is an optional part, it is of course possible to adopt a configuration in which the optional part is not mounted. In this case, in order to provide functions for adjusting the volume and receiving power from the vehicle, a basic unit including a volume dial 53 mounted in the case 51 of the target detection unit 50, a DC jack 55, and the like is prepared. The basic unit may be integrated with the main body by the nut member 40. That is, the nut member 40 can also be used when a basic unit is obtained by removing components necessary for detecting a target such as a radio wave receiver from among components mounted in the case 51 of the target detection unit 50. Further, since the volume dial 53 and the like are smaller in size than the radio wave receiver, the length of the basic unit in the axial direction may be shortened to reduce the size of the entire drive recorder. Of course, the nut member and the basic unit may be integrally formed.

  Further, the volume is adjusted by operating the switch unit 20 provided in the main body 10 and by providing a function for transmitting / receiving an operation signal by the remote control, and the DC jack is connected to the opposite side of the main body 10 (SD card slot). When the optional member is present, the first connector 15 is used for communication with the optional member or power supply from the main body side to the optional member side. When an option such as the target object detection unit 50 is not mounted, a nut member having a short width may be mounted to fix the mounting bracket 30 only.

  16 and 17 show another embodiment of the present invention. In this embodiment, the optional parts connected to the main body 10 are different. That is, two main bodies in the above-described embodiment are prepared, the mounting bracket 30 is attached to one main body 10, the other main body 10 'is turned upside down, and the CCD camera 13 is positioned on the same surface side. In the state, the two main bodies 10 and 10 'are connected and integrated through the connecting member 70. At this time, the main body 10 'has the same configuration as the main body 10, but a dedicated main body 10' may be prepared as an additional main body.

  The connecting member 70 is internally threaded on both sides in the axial direction, and both ends can rotate freely with respect to each other. Thereby, both ends of the connecting member 70 can be rotated and connected to the male threads 18 of the main bodies 10 and 10 ′ that face each other independently. In a state where both the main bodies 10 and 10 'are connected, the CCD camera provided in both the main bodies 10 and 10' is set to be fixed at a position where the shooting areas and shooting directions match as much as possible.

  The connecting member 70 connects the first connector 15 provided on the main body 10, 10 ′. Although not shown, the connecting member 70 includes a DC jack at a predetermined position of the connecting member 70, and from the vehicle side via the DC jack. A power supply function is provided for supplying the supplied power to the main bodies 10 and 10 '. This power supply function includes a connector connected to a connector portion coupled to the second connector of the target object detection unit 50, a DC jack, and wiring for connecting the DC jack to the connector.

  An image captured by the CCD camera 13 of the added main body 10 ′ is sent to the main main body 10 side via the first connector 15 connecting member 70. On the main body 10 side, it can be recorded as a stereo camera based on the image captured by its own CCD camera 13 and the transmitted image. A stereo camera is preferable because it can be used for analysis of accidents because the distance can be obtained from the difference between the images of both cameras. When the control unit of the main body 10 operates alone, it functions as an ordinary drive recorder, records necessary information when an accident occurs, and recognizes that the expanded main body 10 'is connected. Has a function of operating as a stereo camera. Whether or not the expanded main body 10 ′ is connected can be recognized by the function of confirming whether or not an optional component is connected and, if connected, the type thereof. That is, the other party can be confirmed by communicating (establishing a connection) with the other party connected via the first connector. Further, the added main body 10 'sends the image captured as described above to the other party, but may further have a function of recording it in its own nonvolatile memory. In that case, the additional main body 10 'functions as a normal drive recorder, and even if there is a problem in recording with the stereo camera on the main body 10 side, information as a normal drive recorder can be secured.

  When data is recorded on the SD card in each of the main bodies 10 and 10 ', the recorded data of the two SD cards is read out by the PC, and based on synchronization data such as shooting time data included in both data, It is good to reproduce | regenerate by synchronizing the data of two images | videos.

Since the two main bodies 10 and 10 'start and end recording with different sensors,
There may be a deviation in the recording range, but this deviation can be dealt with by performing appropriate correction processing such as correction based on time information or the like and creation of a stereo image based on frames taken at the same time. .

  Further, the inside of the connecting member 70 is provided with a through hole penetrating from the main body 10 side to the main body 10 'side, and electrical connection may be performed via a cable passing through the through hole. Further, the main body 10 may be fixed so that the direction in which the front of the vehicle is photographed is directed and the main body 10 ′ is directed toward the rear side of the vehicle or the interior of the vehicle. In this way, a plurality of directions can be photographed simultaneously. Since the main body 10 is easy to attach and detach, for example, it is usually used by attaching one main body to two cars one by one and combining two main bodies into one car only when a stereo image is required. It can be easily reattached and used. Further, in the main body 10, 10 ', information on the mounting angle of both (for example, information output from the acceleration sensor provided in the main body 10) is recorded on the SD card, and the information on the SD card is captured by the PC. Display (shown) the mounting direction of each main unit based on information about the mounting angles of the two main units, and display the video and vehicle behavior recorded by the function of the drive recorder, using the PC application software (viewer) Or the like may be performed on the basis of information on the mounting angles of the two main bodies.

  Optional parts are not limited to the above-described target detection device or the second drive recorder. For example, a camera recording device for indoor shooting (measures against taxi robbery, etc.), a security device, a snooze prevention device, etc. Various types can be incorporated.

  In addition, the connection of options is not limited to one that is performed on the main body, but a similar structure is provided on the side opposite to the main body side of the option unit so that more options can be connected. It is better to be able to connect the same or different).
