Mode for Carrying Out the Invention

[0011] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In all the drawings, the same components are denoted by the same reference numerals, and the description will be omitted as appropriate.

[0012] <First Embodiment> (Drive Recorder 1) FIG. 1 is a perspective view of a drive recorder 1 according to the first embodiment. FIG. 2 is a side view of the drive recorder 1 according to the first embodiment. In the first embodiment, the drive recorder 1 is provided inside a vehicle. In the first embodiment, the drive recorder 1 is brought in from the outside of the vehicle and attached to the front glass 40 of the vehicle. In the first embodiment, the drive recorder 1 includes a fixing unit 10, a main body unit 20, and an imaging unit 30.

[0013] (Fixing Unit 10) The fixing unit 10 includes a fixing portion 11 and a vibration portion 12 (not shown). The fixing portion 11 is a portion for fixing the drive recorder 1 to the front glass 40 of the vehicle. In a state where the drive recorder 1 is fixed (adhered) to the front glass 40, the fixing portion 11 and the front glass 40 are in contact with each other. A double-sided tape is provided on the pedestal surface of the fixing portion 11 on the side of the front glass 40, and the fixing unit 10 is adhered to the front glass 40 by the double-sided tape.

[0014] The vibration unit 12 (not shown) is built into the fixing unit 10. The vibration unit 12 is installed so as to contact the front glass 40 when the fixing part 11 is fixed to the front glass 40. In this case, the vibration unit 12 directly applies vibration to the front glass 40. Alternatively, the vibration unit 12 may be installed on the front glass 40 in such a manner that it does not contact the front glass 40 but sandwiches a part of the fixing part 11 when the fixing part 11 is fixed to the front glass 40. In this case, the vibration unit 12 applies vibration to the front glass 40 via the fixing part 11.

[0015] (Main body unit 20) The main body unit 20 is the part that forms the main body of the drive recorder 1. The main body unit 20 is a unit that is attached to the fixing unit 10. The main body unit 20 is attached to the front glass 40 via the fixing unit 10. The main body unit 20 includes a display unit 23. The display unit 23 is a display, and an image captured by the first imaging unit 32 described later can be displayed on the display unit 23.

[0016] (Imaging unit 30) The imaging unit 30 is a unit that is attached to the main body unit 20. The imaging unit 30 includes a detection unit 31 (not shown), a first imaging unit 32, and a second imaging unit 33. The detection unit 31 is built into the imaging unit 30. The detection unit 31 detects moving objects (such as people) around or inside the vehicle while the vehicle is parked or stopped.

[0017] The first imaging unit 32 is a camera that images the front direction DR1 of the vehicle. The second imaging unit 33 is a camera that images at least one of the inside and the periphery of the vehicle. The second imaging unit 33 is, for example, a fish-eye lens camera capable of 360-degree omnidirectional imaging. The first imaging unit 32 and the second imaging unit 33 are cameras for recording images of the vehicle during travel and images around or inside the vehicle while the vehicle is parked or stopped.

[0018] (Control unit 21) The main body unit 20 further includes a control unit 21. When the movement of the moving object detected by the detection unit 31 satisfies a predetermined condition, the control unit 21 controls the vibration unit 12 to apply vibration to the windshield 40. By the vibration unit 12 applying vibration to the windshield 40, so to speak, the windshield 40 serves as a diaphragm of a speaker and can emit sounds such as warning sounds to the outside.

[0019] The above-mentioned predetermined condition is, for example, the case where a moving object is continuously detected within a predetermined distance from the detection unit 31 for a first predetermined time (for example, 60 seconds) or more. As another example, the above-mentioned predetermined condition is, for example, the case where a moving object is continuously detected near the vehicle door for a second predetermined time (for example, 10 seconds) or more.

[0020] FIG. 3 is a diagram showing a state of removing the main body unit 20 according to the first embodiment from the fixing unit 10. The main body unit 20 (and the imaging unit 30) is detachable from the fixing unit 10. In the first embodiment, the main body unit 20 is detachable from the fixing unit 10 by sliding in a horizontal one-way direction DR2 with respect to the fixing unit 10. The one-way direction DR2 is the width direction of the vehicle and is a direction orthogonal to the front direction of the vehicle.

[0021] FIG. 4 is a perspective view of the fixing unit 10 after the main body unit 20 according to the first embodiment is removed. FIG. 5 is a diagram showing the internal state of the fixing unit 10 according to the first embodiment. The fixing unit 10 further includes a first electrical contact 13, a housing portion 14, and a recess 15. The first electrical contact 13 is a conductor and is electrically connected to the vibration unit 12. In a state where the main body unit 20 is removed from the fixing unit 10, the first electrical contact 13 is exposed.

[0022] The housing portion 14 is a housing having a box shape. The housing portion 14 is attached to the fixing portion 11 so as to store the vibration unit 12. In the first embodiment, the vibration unit 12 has a vibration speaker. The vibration speaker is stored in the housing portion 14.

[0023] The housing part 14 is formed with a plurality of screw holes 16. In the first embodiment, four screw holes 16 are formed in the housing part 14. The screw holes 16 are provided on the side corresponding to the main body unit 20. The housing part 14 is screwed to the fixing part 11 through the screw holes 16 from the side of the main body unit 20.

[0024] The housing part 14 is detachable from the fixing part 11 fixed to the front glass 40 in a state where the main body unit 20 is removed from the fixing unit 10. That is, even in a state where the fixing part 11 remains adhered to the front glass 40, the housing part 14 can be removed from the fixing part 11 by removing the screws attached to the housing part 14.

[0025] The concave part 15 has a groove-like shape and is a part that fits with a convex part 24 described later. The concave part 15 extends in a direction orthogonal to the one direction DR2.

[0026] FIG. 6 is a perspective view of the main body unit 20 after being removed from the fixing unit 10 according to the first embodiment. The main body unit 20 further includes a second electrical contact 22 and a convex part 24. The second electrical contact 22 is a conductor and is electrically connected to a control part 21 (not shown) built in the main body unit 20. In a state where the main body unit 20 is removed from the fixing unit 10, the second electrical contact 22 is exposed.

[0027] The convex part 24 protrudes from the surface of the main body unit 20 facing the fixing unit 10. The convex part 24 is a part that fits with the concave part 15. By fitting the convex part 24 and the concave part 15, the main body unit 20 is attached (fixed) to the fixing unit 10. In a state where the main body unit 20 is attached to the fixing unit 10, the first electrical contact 13 and the second electrical contact 22 are in contact with each other and are electrically connected. In this way, the control part 21 and the vibration part 12 are electrically connected.

[0028] FIG. 7 is a diagram showing a hardware configuration example of the control unit 21. The control unit 21 includes a bus 1010, a processor 1020, a memory 1030, a storage device 1040, an input / output interface 1050, and a network interface 1060.

[0029] The bus 1010 is a data transmission path for the processor 1020, the memory 1030, the storage device 1040, the input / output interface 1050, and the network interface 1060 to transmit and receive data to and from each other. However, the method of connecting the processor 1020 and the like to each other is not limited to bus connection.

[0030] The processor 1020 is a processor implemented by a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), or the like.

[0031] The memory 1030 is a main storage device implemented by a RAM (Random Access Memory) or the like.

[0032] The storage device 1040 is an auxiliary storage device implemented by an HDD (Hard Disk Drive), an SSD (Solid State Drive), a removable medium such as a memory card, or a ROM (Read Only Memory), and has a recording medium. This recording medium stores program modules for realizing each function of the control unit 21. By the processor 1020 loading these program modules onto the memory 1030 and executing them, each function corresponding to the program module is realized.

[0033] The input / output interface 1050 is an interface for connecting the control unit 21 and various input / output devices. For example, the control unit 130 communicates with the vibration unit 12, the display unit 23, the first imaging unit 32, the second imaging unit 33, and the detection unit 31 via the input / output interface 1050.

[0034] The network interface 1060 is an interface for connecting the control unit 21 to a network. This network is, for example, a LAN (Local Area Network) or a WAN (Wide Area Network). The method by which the network interface 1060 connects to the network may be a wireless connection or a wired connection.

[0035] As described above, the drive recorder 1 according to the first embodiment includes a fixing portion 11, a vibrating portion 12, a detecting portion 31, and a control unit 21. A drive recorder that emits a warning sound when detecting a suspicious person inside or around the vehicle requires a speaker for emitting the warning sound. The drive recorder 1 according to the first embodiment has a configuration integrated with the vibrating portion 12 (vibration speaker), and by vibrating the windshield 40 to substitute for the speaker, it is not necessary to separately provide a speaker in the vehicle other than the drive recorder 1. As a result, the man-hours for attaching a separate speaker to the vehicle can be reduced, and the manufacturing cost can also be suppressed. Therefore, a drive recorder with a speaker can be easily introduced.

[0036] Furthermore, the main body unit 20 according to the first embodiment is detachable from the fixing unit 10. The fixing unit is fixed to the windshield with a strong double-sided tape and is difficult to remove. Therefore, if the main body unit fails, it is difficult to remove it from the windshield together with the main body unit. However, since the main body unit 20 according to the first embodiment can be detached from the fixing unit 10, even if the main body unit 20 fails, the main body unit 20 can be easily separated from the fixing unit 10. That is, the maintainability of the drive recorder 1 can be improved.

[0037] Furthermore, the main body unit 20 according to the first embodiment is detachable from the fixing unit 10 by sliding in a horizontal one-way direction DR2 with respect to the fixing unit 10. Thereby, when the main body unit 20 is removed from the fixing unit 10, it is possible to suppress the main body unit 20 from hitting the windshield 40 and becoming difficult to remove. Furthermore, it is possible to suppress the main body unit 20 from falling due to its own weight.

[0038] <Second Embodiment> FIG. 8 is a side view of the drive recorder 1 according to the second embodiment. The imaging unit 30 according to the second embodiment is attached to the main body unit 20 and is rotatable with respect to the main body unit 20. The imaging unit 30 according to the second embodiment is configured to be rotatable with respect to a certain axis point C of the main body unit 20 in a plane orthogonal to the one-way direction DR2 (the depth direction of the paper surface of FIG. 8) shown in FIG. 3.

[0039] The display surface 25 of the display unit 23 according to the second embodiment is substantially parallel to the extending surface 41 along which the windshield 40 extends. When the display surface 25 is substantially parallel to the extending surface 41, it means a case where, in a plane orthogonal to the one-way direction DR2, the angle formed by the direction DR3 in which the display surface 25 extends and the direction DR4 in which the extending surface 41 extends is -15° or more and 15° or less.

[0040] FIG. 9 is a side view of the imaging unit 30 according to the second embodiment. DR5 is the shooting center direction of the first imaging unit 32. The shooting center direction DR5 is the shooting direction of the first imaging unit 32 and is the direction passing through the center of the lens of the first imaging unit 32. DR6 is the shooting center direction of the second imaging unit 33. The shooting center direction DR6 is the shooting direction of the second imaging unit 33 and is the direction passing through the center of the lens of the second imaging unit 33.

[0041] In the second embodiment, the shooting center direction DR6 of the second imaging unit 33 is substantially perpendicular to the shooting center direction DR5 of the first imaging unit 32. The case where the shooting center direction DR6 is substantially perpendicular to the shooting center direction DR5 means that the angle θ formed by the shooting center direction DR6 and the shooting center direction DR5 is, for example, 75° or more and 105° or less. Incidentally, by setting the angle θ formed with the shooting center direction DR5 to, for example, 90° or more and 105° or less, when the shooting center direction DR6 of the second imaging unit 33 is inclined not to the front side of the vehicle but to the rear side of the vehicle, the inside of the vehicle can be imaged more effectively.

[0042] As described above, the drive recorder 1 according to the second embodiment includes an imaging unit 30 including a first imaging unit 32 and a second imaging unit 33, and a main body unit 20 including a display unit 23. The imaging unit 30 is attached to the main body unit 20 and is rotatable with respect to the main body unit 20. Thereby, the image captured by the first imaging unit 32 can be displayed on the display unit 23. Therefore, the imaging unit 30 can be adjusted in angle so that the first imaging unit 32 captures the front (the forward direction DR1 of the vehicle) while looking at the display unit 23 (so that the shooting center direction DR5 of the first imaging unit 32 faces the forward direction DR1 of the vehicle). Thereby, the shooting direction of the drive recorder 1 can be set appropriately.

[0043] Furthermore, the shooting center direction DR6 of the second imaging unit 33 is substantially perpendicular to the shooting center direction DR5 of the first imaging unit 32. Thereby, when the first imaging unit 32 is adjusted to face the forward direction DR1 of the vehicle, the second imaging unit 33 automatically faces downward (substantially the vertical direction). Therefore, by adjusting the angle of the first imaging unit 32, the angle adjustment of the second imaging unit 33 becomes unnecessary. Therefore, even if there are two imaging units, namely the first imaging unit 32 and the second imaging unit 33, the angle adjustment of the imaging unit 30 can be performed appropriately and effectively.

[0044] Furthermore, the imaging center direction DR6 of the second imaging unit 33 is substantially perpendicular to the imaging center direction DR5 of the first imaging unit 32. Thus, when the first imaging unit 32 is adjusted to face the front direction DR1 of the vehicle, the second imaging unit 33 automatically faces downward (substantially the vertical direction). Therefore, the angle adjustment of the second imaging unit 33 becomes unnecessary. Accordingly, the angle adjustment of the imaging unit 30 can be effectively performed.

[0045] <Third Embodiment> FIG. 10 is a view of the imaging unit 30 according to the third embodiment as seen from the display surface 25 side. In FIG. 10, it represents a view of the imaging unit 30 as seen from the direction opposite to the first imaging unit 32. The imaging unit 30 according to the third embodiment further includes a detection unit 31 that detects moving objects around the vehicle or inside the vehicle. The detection unit 31 is provided on the side of the imaging unit 30 opposite to the first imaging unit 32. The detection unit 31 is built into the imaging unit 30.

[0046] The detection unit 31 according to the third embodiment includes a plurality of electromagnetic wave sensors. Each of the plurality of electromagnetic wave sensors detects a moving object by irradiating an electromagnetic wave. The electromagnetic wave sensor irradiates an electromagnetic wave at least toward the door of the vehicle. In the third embodiment, the detection unit 31 includes two electromagnetic wave sensors (31a, 31b), and the two electromagnetic wave sensors 31a, 31b are arranged symmetrically with respect to the imaging center direction DR6.

[0047] FIG. 11 is a view showing the irradiation directions of the electromagnetic waves of the detection unit 31 according to the third embodiment. Each of the central directions (DR7a, DR7b) of the irradiation of the electromagnetic waves of the plurality of electromagnetic wave sensors (detection unit 31) is inclined with respect to the opposite direction DR8 of the imaging center direction DR5 of the first imaging unit 32 in the horizontal plane (a plane perpendicular to the height direction of the vehicle 2). The central direction of the irradiation of the electromagnetic wave of the electromagnetic wave sensor is inclined toward the rear side of the vehicle 2 with respect to the width direction (one direction DR2) of the vehicle in the horizontal plane.

[0048] DR7a is the central direction of the irradiation of the electromagnetic wave sensor 31a. The electromagnetic wave sensor 31a irradiates electromagnetic waves within a predetermined range α1 centered on the central direction DR7a. DR7b is the central direction of the irradiation of the electromagnetic wave sensor 31b. The electromagnetic wave sensor 31b irradiates electromagnetic waves within a predetermined range α2 centered on the central direction DR7b.

[0049] In addition, in the third embodiment, the second imaging unit 33 may be omitted, and the imaging unit 30 may be configured to include the first imaging unit 32 and the detection unit 31.

[0050] As described above, the drive recorder 1 according to the third embodiment includes an imaging unit 30 including a first imaging unit 32 and a detection unit 31, and a main body unit 20 including a display unit 23. The imaging unit 30 is attached to the main body unit 20 and is rotatable with respect to the main body unit 20. The detection unit 31 includes a plurality of electromagnetic wave sensors that detect moving objects by irradiating electromagnetic waves.

[0051] Thus, if the imaging unit 30 is adjusted in angle so that the first imaging unit 32 captures an image of the front (the forward direction DR1 of the vehicle) while viewing the image captured by the first imaging unit 32, the irradiation direction of the electromagnetic waves is automatically determined to be an appropriate direction without adjusting the angle of the detection unit 31 (electromagnetic wave sensor). Therefore, moving objects can be appropriately detected.

[0052] <Fourth Embodiment> As shown in FIGS. 2, 4, and 6, the drive recorder 1 according to the fourth embodiment includes a fixed unit 10 fixed to the windshield of the vehicle and a main body unit 20 removable from the fixed unit 10. The fixed unit 10 according to the fourth embodiment includes a fixing portion 11, a vibrating portion 12, and a first electrical contact 13. The main body unit 20 according to the fourth embodiment includes a detection unit 31, a control unit 21, and a second electrical contact 22. Also in the fourth embodiment, when the main body unit 20 is attached to the fixed unit 10, the first electrical contact 13 and the second electrical contact 22 are in contact with each other.

[0053] As described above, the drive recorder 1 according to the fourth embodiment may be configured such that the main body unit 20 includes the detection unit 31.

[0054] Also in the fourth embodiment, even when the main body unit 20 fails, it is possible to easily separate the main body unit 20 from the fixing unit 10 without removing the fixing portion 11 from the front glass 40, and the maintainability of the drive recorder 1 can be improved.

[0055] <Fifth Embodiment> As shown in FIGS. 2, 4, and 5, the drive recorder 1 according to the fifth embodiment includes a fixing unit 10 including a fixing portion 11, a vibration unit 12, and a housing unit 14, a detection unit 31, and a control unit 21, and a main body unit 20 that is detachable from the fixing unit 10. The housing unit 14 is detachable from the fixing portion 11 fixed to the front glass 40 when the main body unit 20 is removed from the fixing unit 10.

[0056] Also in the drive recorder 1 according to the fifth embodiment, the main body unit 20 may be configured to include the detection unit 31.

[0057] Also in the fifth embodiment, even when the main body unit 20 fails, it is possible to easily separate the main body unit 20 from the fixing unit 10 without removing the fixing portion 11 from the front glass 40. Further, since the housing unit 14 can be removed while the fixing portion 11 is fixed to the front glass 40, even when the vibration unit 12 (vibration speaker) fails, the vibration unit 12 inside the fixing unit 10 can be easily removed. That is, the maintainability of the drive recorder 1 can be improved.

[0058] As described above, the embodiments have been described with reference to the drawings, but these are examples of the present invention, and various configurations other than the above can also be adopted.

[0059] In the first embodiment, the main body unit 20 may include a detection unit 31, a first imaging unit 32, and a second imaging unit 33. That is, the main body unit 20 may be configured to include an imaging unit 30.
