Description

  The present invention relates to a drive recorder that captures and records a situation around a vehicle.

  2. Description of the Related Art Conventionally, a drive recorder that captures and records a situation around a vehicle is known as a material used for investigating the cause when a traffic accident or the like occurs.

  For example, Patent Document 1 records a camera unit (fixed camera unit) provided on the inner surface of a windshield of a vehicle and having a fixed angle of a lens that images the front of the vehicle and an image captured by the camera unit. A drive recorder in which a main body is integrally formed is described.

  By the way, the inclination angle of the windshield of the vehicle varies depending on the vehicle type. Therefore, in a drive recorder having a fixed camera unit such as the drive recorder described in Patent Document 1, the direction of the optical axis of the camera is determined by the tilt angle of the windshield. The surrounding situation may not be imaged.

  For this reason, a drive recorder has been developed in which a main body part and a camera part (movable camera part) capable of angle adjustment are integrated. In a drive recorder in which the main unit and the movable camera unit are configured integrally, the angle of the camera unit can be adjusted according to the shape of the window glass, and therefore an image of an appropriate imaging range can be acquired. Is possible.

JP 2008-158913 A

  However, the drive recorder in which the main body unit and the movable camera unit are integrally formed has a problem that even if the angle of the camera unit is adjusted, the situation around the vehicle may not be captured in an appropriate imaging range.

  Specifically, in the drive recorder, a lens having a wide angle of view is used in order to perform imaging in a wide imaging range. Therefore, in a drive recorder in which the movable camera unit and the main body unit are integrally provided, even if the angle of the camera unit is appropriately adjusted, the main body unit enters the imaging range at the appropriately adjusted angle. There is a problem in that an appropriate image around the vehicle cannot be obtained because the main body portion is reflected in the image.

  Further, as described above, since the vehicle window glass has a different inclination angle depending on the vehicle type, in the drive recorder in which the main body unit and the movable camera unit are configured integrally, when the angle of the camera unit is adjusted, the camera unit Sometimes touched the window glass.

  In such a drive recorder, since the angle of the camera unit cannot be adjusted to an appropriate angle, it is not possible to capture an image within an appropriate imaging range, and as a result, there is a problem that an image around the vehicle cannot be obtained. It was.

  As a method for solving this, a method of preparing a separate bracket and fixing the drive recorder to the vehicle so as not to interfere with the window glass using this bracket is conceivable. There are problems such as high.

  For these reasons, it has become a major issue how to realize a drive recorder that can image the situation around the vehicle in an appropriate imaging range regardless of the inclination angle and shape of the window glass.

  The present invention has been made to solve the above-described problems caused by the prior art, and an object of the present invention is to provide a drive recorder that can image a situation around a vehicle in an appropriate imaging range.

  In order to solve the above-described problems and achieve the object, the present invention is a drive recorder attached to a window glass of a vehicle, and a sticking surface for attaching to the window glass on a surface facing the window glass A main body provided with a convex portion having a diameter larger than the thickness of the main body portion, and the height of the portion protruding from the surface of the main body portion facing the window glass is smaller than the height of the convex portion. And a camera unit having a lens that moves along the outer periphery of the diameter.

  According to the present invention, there is an effect that a situation around the vehicle can be imaged within an appropriate imaging range.

  Embodiments of a drive recorder according to the present invention will be described below in detail with reference to the accompanying drawings. In the following, the outline of the drive recorder according to the present invention will be described with reference to FIG. 1, and then an embodiment of the drive recorder according to the present invention will be described with reference to FIGS.

  FIG. 1 is a diagram showing an outline of a drive recorder 10 according to the present invention. As shown in FIG. 1, the drive recorder 10 is a device that is attached to a vehicle interior side surface of a windshield g of a vehicle and images and records a situation in front of the vehicle.

  The drive recorder 10 includes a camera unit 11 that captures a situation in front of the vehicle and a main body unit 12 that includes a processing unit that performs processing for recording an image captured by the camera unit 11.

  Moreover, the main-body part 12 has the convex part 12a which has the planar top surface used as the sticking surface (henceforth a "sticking surface") for attaching to the windshield g on the surface on the side facing the windshield g. It has.

  In addition, the camera unit 11 has a diameter larger than the thickness of the main body part, and a flat surface side (front glass g side) including a sticking surface of the convex part 12a from a flat surface s including the surface of the main body part 12 facing the windshield g ) A cylindrical casing 11a having an outer periphery where the height d1 of the protruding portion is smaller than the height d2 of the convex part 12a, and a predetermined image from the casing 11a while moving along the outer periphery of the casing 11a. And a lens 11b that images the outside of the vehicle at a corner w.

  That is, the camera unit 11 has a diameter larger than the thickness of the main body (thickness in the direction perpendicular to the surface s facing the windshield g) and the surface s of the main body 12 facing the windshield g. The imaging lens 11b moves along an outer periphery having a smaller diameter d1 than the height d2 (thickness in the direction perpendicular to the pasting surface) to the pasting surface of the convex portion 12a.

  And when installing this drive recorder 10 in the windshield g, the top surface of the convex part 12a is made into the compartment of the windshield g so that the surface of the main body part 12 attached to the windshield g and the windshield g face each other. Stick to the inner surface. The sticking and fixing is performed using an elastic double-sided tape using foamed rubber or the like as the core material.

  Subsequently, the imaging range of the camera unit 11 is adjusted by rotating the lens 11b along the outer periphery of the housing 11a so that the lens 11b of the camera unit 11 is directed forward of the vehicle. Thereby, the drive recorder 10 can image the situation ahead of the vehicle in an appropriate imaging range.

  At this time, in the drive recorder 10, there is a sufficient gap corresponding to the height (thickness) d2 of the convex portion 12a between the front glass g and the surface of the main body portion 12 facing the windshield g. For this reason, in the drive recorder 10, even if the lens 11b is rotated to the position closest to the windshield g, the lens 11b does not contact the windshield g.

  Therefore, the drive recorder 10 may be installed on the windshield having a larger inclination angle with respect to the horizontal plane (the angle perpendicular to the ground) than the windshield g shown in FIG. 1, and the lens 11b may be rotated so as to face the front of the vehicle. The lens 11b does not contact the windshield.

  Moreover, in the drive recorder 10, a part of the outer periphery of the casing 11 a of the camera unit 11 is formed so as to protrude toward the windshield g with respect to the main body unit 12, and the lens 11 b is formed on the outer periphery of the casing 11 a of the camera unit 11. It is comprised so that it may rotate along.

  Therefore, even when the drive recorder 10 rotates the lens 11b to the position closest to the surface of the main body 12 facing the windshield g, the angle of view w of the lens 11b, that is, the imaging range. The main body portion 12 does not enter the space.

  Moreover, when the convex part 12a is seen from the side, it is comprised by the trapezoid shape where an upper side (sticking surface side) is shorter than a lower side (drive recorder side). Thereby, the edge part of the convex part 12a is prevented from entering the angle of view w of the lens 11b.

  As described above, in the drive recorder 10, the lens 11b does not come into contact with the windshield g even when the lens 11b is rotated, and the main body 12 does not enter the imaging range. An image captured in an appropriate imaging range can be acquired regardless of the angle.

  Below, the Example about the drive recorder 10 demonstrated using FIG. 1 is described in detail.

  FIG. 2 is a perspective view showing an appearance of the drive recorder 1 according to the present embodiment. Below, drive recorder 1 installed in the windshield of vehicles and imaging the situation ahead of vehicles is explained. In addition to the windshield, the drive recorder 1 can be installed at any location as long as the situation around the vehicle can be imaged, such as the rear glass of the vehicle, the ceiling in the vehicle interior, and the dashboard.

  As shown in FIG. 2, the drive recorder 1 includes a camera unit 2 having a substantially cylindrical casing (hereinafter referred to as “cylinder 20”), and a box-shaped casing 30 having a predetermined thickness D. And a main body 3 having The camera unit 2 is configured integrally with the main body 3 in a state in which a part of the peripheral surface of the cylinder 20 enters the inside of the housing 30 of the main body 3.

  In the following, for the sake of convenience, of the surfaces constituting the housing 30 of the main body 3, the surface denoted by reference numeral 31 in FIG. 2 is referred to as the upper surface of the main body 3, and the surface facing the upper surface 31 is the lower surface of the main body 3. That is to say.

  Hereinafter, among the surfaces constituting the housing 30 of the drive recorder 1, a surface parallel to the circular surface of the cylinder 20 is referred to as a side surface.

  The camera unit 2 includes a lens 21 that rotates along the peripheral surface of the cylinder 20 inside the cylinder 20, and changes the angle of view, that is, the imaging range by adjusting the rotation angle of the lens 21. An imaging device that images the situation around the vehicle.

  2 is a fixing member (screw) for fixing the position of the rotated lens 21. In the drive recorder 1, the position of the lens 21, that is, the imaging direction by the lens 21 is fixed by inserting and fixing (screwing) the fixing member 22 into a fixing hole provided inside the cylinder 20.

  That is, the fixing member 22 is configured to fix the housing 30 and the camera unit 2 with screws. The imaging direction is determined by selecting a fixing hole into which the fixing member 22 is inserted.

  The camera unit 2 is formed so that the diameter of the cylinder 20 is larger than the thickness D of the main body 3, and a part of the peripheral surface of the cylinder 20 includes the upper surface 31 of the main body 3 in a side view. It is configured integrally with the main body 3 in a state where it protrudes above the plane (outside of the main body 3).

  The main body unit 3 includes a recording unit that records an image of the situation around the vehicle imaged by the camera unit 2 inside. On the upper surface 31 of the main body 3, there is provided a convex portion 32 having a sticking surface 321 for sticking the drive recorder 1 to the windshield of the vehicle.

  2 is a double-sided tape for adhering the drive recorder 1 to the windshield, and reference numeral 34 is a wiring lead-out portion for drawing out wiring from the drive recorder 1.

  In particular, the convex portion 32 has a thickness larger than the difference between the diameter of the cylinder 20 constituting the outer shape of the camera portion 2 and the thickness D of the main body portion 3. That is, the convex portion 32 is formed such that the height from the upper surface 31 of the main body portion 3 is higher than the height of the protruding portion of the cylinder 20 protruding above the upper surface 31 of the main body portion 3 in a side view. Yes.

  In other words, the upper flat surface (double-sided tape application surface) of the convex portion 32 will be described. The convex portion 32 is formed so that the plane formed by the upper surface of the convex portion 32 does not intersect the camera portion 2.

  Thus, when the drive recorder 1 is attached to the windshield, the lens 21 and the windshield do not come into contact with each other even if the lens 21 of the camera unit 2 is rotated to the windshield side.

  Therefore, the drive recorder 1 can adjust the imaging range by rotating the lens 21 to an appropriate position according to the inclination angle of the windshield, which differs depending on the vehicle model to be attached. For this reason, the drive recorder 1 can image the situation around the vehicle in an appropriate imaging range regardless of the inclination angle of the windshield.

  Next, the installation position of the drive recorder 1 will be described with reference to FIG. FIG. 3 is a diagram illustrating an installation position of the drive recorder 1 according to the present embodiment. 3A shows a portion of the windshield G1 when the vehicle is viewed from the front, and FIG. 3B shows a portion of the windshield G1 when the vehicle is viewed from the side.

  As shown in FIG. 3A, the drive recorder 1 is installed on the surface of the windshield G1 on the vehicle interior side. Specifically, the drive recorder 1 is attached to the upper part on the passenger seat side of the windshield G1 via a double-sided tape 33. At this time, the drive recorder 1 is installed so that the lens 21 is within the wiping range W such as raindrops by the wiper.

  Thereby, the drive recorder 1 can image and record the situation ahead of the vehicle without obstructing the driver's view. Further, since the lens 21 is located within the wiper wiping range W, the drive recorder 1 can appropriately capture and record the situation in front of the vehicle even during rain.

  In addition, the drive recorder 1 is installed avoiding the installation location of each antenna when antennas for broadcast reception, GPS (Global Positioning System), ETC (Electronic Toll Collection System), etc. are installed on the windshield G1. It is desirable to do.

  Further, in order to prevent the drive recorder 1 from entering the driver's field of view and hindering the concentration of driving during driving, the passenger seat side near the rearview mirror is preferable as the installation location of the drive recorder 1 (FIG. 3). In the embodiment, from the driver's seat toward the windshield G1, the left side in the vicinity of the rearview mirror).

  Further, as shown in FIG. 3B, the drive recorder 1 is fixed to the windshield G1 so that the camera unit 2 is downward and the main body is upward. By fixing in this way, the vehicle front direction (the shooting direction during operation of the drive recorder) and the drive recorder 1 are compared to the case where the camera unit 2 is fixed to the windshield G1 so that the camera unit 2 is upward and the main body unit is downward. The angle difference in the shooting direction is increased, and the vehicle front image can be shot more efficiently, that is, without useless image components.

  As shown in FIG. 3B, when the vertical height from the lowest point of the windshield G1 to the highest point is H, the drive recorder 1 moves from the highest point of the windshield G1 to the vertically lower side. The drive recorder 1 is installed at a position where the entire drive recorder 1 can be accommodated up to 0.2H. Thereby, the drive recorder 1 can image the situation ahead of the vehicle in an appropriate imaging range without obstructing the driver's view.

  Next, an installation mode when the drive recorder 1 is installed in a vehicle having a different windshield inclination angle will be described with reference to FIG. FIG. 4 is a diagram illustrating an installation mode when the drive recorder 1 according to the present embodiment is installed in a vehicle having a different windshield inclination angle.

  FIG. 4 (A) shows an installation mode when the drive recorder 1 is installed in a general passenger car in which the inclination angle of the windshield G1 with respect to the horizontal plane is relatively small. In FIG. 4 (B), The installation mode in the case where the drive recorder 1 is installed in a large vehicle such as a bus or a truck whose inclination angle of the windshield G2 with respect to the horizontal plane is larger than that of a passenger car is shown.

  As shown in FIG. 4 (A), when the drive recorder 1 is installed on a windshield G1 of a general passenger car, the main body is provided with a double-sided tape 33 provided on the top surface (sticking surface 321 shown in FIG. 2) of the convex portion 32. It sticks so that the upper surface 32 of the part 1 and the windshield G1 may oppose in parallel.

  Subsequently, the lens 21 is rotated along the peripheral surface of the cylinder 20 so that the lens 21 is horizontally directed toward the front of the vehicle, and the direction of the lens 21 is fixed by the fixing member 22 (see FIG. 2).

  As described above, the drive recorder 1 can image and record the situation ahead of the vehicle in an appropriate imaging range by appropriately adjusting the direction of the lens 21 after being attached to a predetermined position of the windshield G1. it can.

  As shown in FIG. 4B, when the drive recorder 1 is installed on the windshield G2 of a large vehicle, the upper surface of the main body 1 is similarly provided by the double-sided tape 33 provided on the sticking surface 321 of the convex portion 32. 32 and windshield G2 are stuck so as to face each other in parallel.

  Subsequently, the lens 21 is rotated along the peripheral surface of the cylinder 20 so that the lens 21 is horizontally directed toward the front of the vehicle, and the direction of the lens 21 is fixed by the fixing member 22 (see FIG. 2).

  By the way, the windshield G2 of a large vehicle generally has a larger inclination angle with respect to the horizontal plane than the windshield G1 of a passenger car and is erected in a state of being nearly perpendicular to the horizontal plane. For this reason, when the drive recorder 1 is installed in a large vehicle, in order to turn the lens 21 forward of the vehicle, the camera unit 2 is rotated until the angle between the direction in which the lens 21 faces and the windshield G2 is nearly vertical. Let

  Here, in the drive recorder 1, as described above, the diameter of the cylinder 20 of the camera unit 2 is formed larger than the thickness D of the housing 30 of the main body unit 3. Specifically, the drive recorder 1 is formed such that a part of the peripheral surface of the cylinder 20 of the camera unit 2 protrudes toward the windshield G2 from a plane including the upper surface 31 of the main body unit 3 in a side view.

  For this reason, in the drive recorder 1, when the lens 21 is rotated until the angle between the direction in which the lens 21 is directed and the windshield G <b> 2 is nearly vertical, the upper surface 31 of the main body 3 is positioned rearward when viewed from the lens 21. Will do. Therefore, in the drive recorder 1, even if the lens 21 is rotated until the angle between the direction in which the lens 21 is directed and the windshield G2 is nearly vertical, the main body 3 does not enter the imaging range.

  Moreover, the drive recorder 1 has a thickness (height) larger than the height of the portion where the peripheral surface of the cylinder 20 of the camera unit 2 protrudes toward the windshield G2 from the plane including the upper surface 31 of the main body 3 in a side view. It is affixed to the windshield G2 through the provided convex part 32. FIG.

  That is, in the drive recorder 1, a sufficient gap formed by the convex portion 32 is formed between the peripheral surface of the cylinder 20 of the camera unit 2 and the windshield G2. For this reason, in the drive recorder 1, even when the camera unit 2 is rotated until the angle between the direction in which the lens is directed and the windshield G2 is nearly vertical, the lens 21 and the windshield G2 are in contact with each other. There is no.

  As described above, the drive recorder 1 does not enter the imaging range even when the camera unit 2 is rotated, and the lens 21 does not come into contact with the windshield G2. Therefore, the drive recorder 1 depends on the inclination angles of the windshields G1 and G2. Therefore, it is possible to image the situation ahead of the vehicle in an appropriate imaging range.

  Next, the shape of the convex portion 32 will be described more specifically with reference to FIG. FIG. 5 is an explanatory diagram of the shape of the convex portion 32. 5A shows the mounting surface side of the drive recorder 1, and in FIG. 5B, the wiring lead-out portion 34 of the drive recorder 1 installed on the curved windshield G3 is provided. The surface on the side is shown.

  As shown in FIG. 5A, the convex portion 32 is formed such that the area of the sticking surface 321 is smaller than the area of the upper surface 31 of the main body portion 3. For this reason, as shown in FIG. 5 (B), when the drive recorder 1 is installed on the curved windshield G3, the drive recorder 1 is affected by the curvature of the windshield G3 because the area to be adhered to the windshield G3 can be reduced. And can be attached to the windshield G3.

  For example, when a drive recorder that does not include the convex portion 32 is attached to the curved windshield G3 using a double-sided tape, the upper surface of the main body 3 is attached to the windshield G3. In such a case, in the drive recorder, a gap may be formed between the central portion of the upper surface of the main body 3 and the windshield G3, and the sticking strength may be reduced.

  Thus, since the drive recorder which is not provided with the convex part 32 may be influenced by the curvature of the windshield G3 when sticking to the windshield G3, it lacks the freedom degree of an installation place. In addition, a drive recorder that does not include the convex portion 32 can be installed on the curved windshield G3 by using another member such as a bracket, but the number of parts increases, which is not preferable in terms of cost.

  Therefore, in the drive recorder 1 of the present embodiment, a convex portion 32 having an adhesive surface 321 having a smaller area than the upper surface 31 is provided on the upper surface 31 of the main body portion 3, and is affixed to the adhesive surface 321 of the convex portion 32. It was set as the structure stuck on the windshield G3 curved by the double-sided tape 33. FIG.

  Thereby, since the drive recorder 1 can be installed without being affected by the curvature of the windshield G3, the degree of freedom of the installation position in the windshield G3 can be improved.

  Therefore, the drive recorder 1 can select and install a position that does not interfere with other members such as an antenna installed on the windshield G3. Moreover, since the drive recorder 1 can be attached to the windshield G3 with only the double-sided tape 33 without using a separate member dedicated for attachment such as a bracket, an increase in cost can also be suppressed.

  Next, the wiring arrangement of the drive recorder 1 will be described with reference to FIG. FIG. 6 is a diagram illustrating a wiring arrangement of the drive recorder 1 according to the present embodiment.

  As shown in FIG. 6, the drive recorder 1 includes a wiring lead-out portion 34 that pulls out the wiring 341 on the side surface of the convex portion 32. In particular, the wiring lead-out portion 34 is provided on the side surface located above in the state where the drive recorder 1 is attached to the windshield G1. The wiring 341 drawn out from the wiring drawing portion 34 is a power supply line that supplies power to the drive recorder 1.

  As described above, the drive recorder 1 includes the wiring lead-out portion 34 at a position closer to the windshield G1 than the main body portion 3 (particularly, on the side surface located above). For this reason, in the drive recorder 1, the wiring 341 can be routed along the inner side surface of the windshield G1 from a position closer to the windshield G1 than the main body 3.

  Moreover, since it arrange | positions in the gap | interval formed by the convex part 32 and the main-body part 3, it can improve the beauty | look at the time of routing of the wiring 341, and it can improve the up-down direction (drive recorder 1 of drive recorder 1 whole). The length from the upper end to the lower end when attached to the windshield G1 can be reduced, and downsizing can be realized.

  Next, the internal structure of the drive recorder 1 will be described. FIG. 7 is a cross-sectional view of the drive recorder 1 according to this embodiment as viewed from the side.

  As shown in FIG. 7, the main body unit 3 of the drive recorder 1 has a circuit board 50 for recording an image captured by the camera unit 2 and a spare for the drive recorder 1 when the vehicle power is turned off. A space for storing a supercapacitor 51 and the like serving as a power source is provided.

  Reference numeral 52 shown in FIG. 7 is a shield that prevents noise from entering the drive recorder 1 and leaking noise from the drive recorder 1 to the outside.

  Moreover, the convex part 32 provided in the upper surface 31 of the main-body part 3 equips an inside with the space connected to the space inside the main-body part 3, and at least one part of the components which should be accommodated in the main-body part 3 in this space is contained. Store. For example, a part having a larger thickness than the other parts such as the supercapacitor 51 is accommodated in the space inside the convex portion 32.

  In addition, the circuit board 50 effectively uses the space inside the convex portion 32 with the arrangement surface of the large component as the convex portion 32 side and the wiring pattern surface (possible arrangement of small chip components) as the opposite direction to the convex portion 32 side. In addition, the use volume of the space inside the main body 3 is suppressed.

  Thus, in the drive recorder 1, since at least a part of the parts to be stored in the main body 3 can be stored inside the convex portion 32, the main body 3 is compared with the case where the convex portion 32 is not provided. The outer shape can be reduced (thinned).

  Thereby, the drive recorder 1 not only can improve the beauty | look, but can improve the freedom degree of the installation location in the windshield G1. Further, by reducing the size (thinning) of the main body 3, the drive recorder 1 is less likely to drop off due to less influence of vibration during operation.

  Moreover, the drive recorder 1 can make the user feel the thickness of the main body part 32 visually thinner by setting the main body part 3 and the convex part 32 to different colors.

  Next, the recording medium insertion / extraction section 4 in the drive recorder 1 will be described with reference to FIG. FIG. 8 is a diagram illustrating the recording medium insertion / extraction section 4 in the drive recorder 1 according to the present embodiment.

  As shown in FIG. 8, an insertion / removal portion 4 for inserting / removing a memory card 41 serving as a recording medium for recording an image picked up by the camera portion 2 is provided on the side surface of the main body portion 3 of the drive recorder 1. ing.

  In consideration of the installation location of the drive recorder 1 (installed on the left side in the vicinity of the room mirror), the insertion / removal unit 4 allows the memory card 41 to be inserted from the left side when the drive recorder 1 is installed. Is provided.

  In a left-hand drive vehicle (a vehicle with a driver's seat on the left side), the drive recorder 1 is preferably installed on the right side in the vicinity of the rearview mirror. When the recorder 1 is installed, the memory card 41 is inserted from the right side. That is, the insertion / extraction part 4 is provided on the side surface opposite to the side surface facing the room mirror.

  For this reason, the drive recorder 1 can easily insert and remove the memory card 41 from the side surface of the main body 3.

  As described above, the camera recorder and the main body are integrally formed in the drive recorder according to the present embodiment. And the main-body part is equipped with the convex part from which the top surface turns into a sticking surface to a window glass in the surface facing a window glass.

  Further, the camera part has a diameter larger than the thickness of the main body part, and the height of the part protruding from the plane including the surface facing the window glass of the main body part to the flat side including the sticking surface is smaller than the height of the convex part. A cylindrical casing having an outer periphery, and a lens that moves along the outer periphery of the casing and images the outside of the vehicle from the casing.

  For this reason, in the drive recorder according to the present embodiment, when the lens is moved to the position closest to the surface facing the window glass of the main body, the main body is positioned obliquely behind the lens with respect to the imaging direction of the lens. Will do.

  Therefore, according to the drive recorder according to the present embodiment, even when the lens is moved to the position closest to the surface of the main body portion facing the window glass, the main body portion does not enter the imaging range.
