Description

In-vehicle device

[0001] The present disclosure relates to an in-vehicle device.

[0002] In-vehicle devices are generally known that include a display unit having a screen for displaying information and an operation unit for a user to input information, and a main unit connected to the display unit. In this type of in-vehicle device, the main unit is large in size and occupies a large area, which reduces its mountability in a vehicle. Therefore, in order to improve mountability in a vehicle, a conventional in-vehicle device has been proposed that includes a gyro sensor as a detector for detecting the orientation of the main unit within the main unit, and that can be installed in multiple ways with different orientations of the main unit relative to the vehicle so that the device can be installed both horizontally and vertically relative to the vehicle (see, for example, Patent Document 1).

[0003] Patent No. 3385851

[0004] In the in-vehicle device of Patent Document 1, a first pin and a second pin are formed to protrude from the gyro sensor (detection unit), and the main body unit (casing) is provided with a first guide groove that guides the first pin, and a second guide groove that extends in a direction perpendicular to the first guide groove and guides the second pin; by guiding the first pin and the second pin in each guide groove, the gyro sensor can be swung in a desired direction.

[0005] However, with the conventional configuration, when the main body is installed horizontally or vertically relative to the vehicle, it is necessary to open the casing and swing the gyro sensor to the desired orientation each time, which makes the operation of adjusting the orientation of the gyro sensor cumbersome, and there is room for improvement in this regard.

[0006] The present disclosure has been made in consideration of the above, and aims to provide an in-vehicle device that can easily adjust the orientation of a detection unit to match the installation direction of a main body unit.

[0007] In order to solve the above-mentioned problems and achieve the object, the in-vehicle device of this embodiment comprises a display unit and a main body unit connected to the display unit, and is configured to be installable in a plurality of forms with different orientations of the main body unit relative to the vehicle, the main body unit having a housing with an opening in a window unit, and a detection unit housed in the housing, the detection unit comprising a pair of guide rails having arc-shaped guide surfaces, a semi-cylindrical support unit having a protrusion on its outer peripheral surface that is exposed to the outside of the housing through the window unit, and supporting a detection board including the detection unit on its inner peripheral surface, and a detection board support member having a pair of sliding portions formed on both ends of the support member and capable of sliding on the guide rails, and by movement of the detection board support member, the detection board can be displaced between a first position where it is arranged along the opening surface of the window unit, and a second position where it is arranged along a direction intersecting the opening surface of the window unit.

[0008] The in-vehicle device according to this embodiment has the advantage that the orientation of the detection unit can be easily adjusted to match the installation direction of the main body unit.

[0010] Hereinafter, a mode for carrying out the invention (hereinafter referred to as an embodiment) will be described in detail with reference to the drawings. Note that the present disclosure is not limited to the embodiment. Furthermore, the components in the embodiment include those that can be easily imagined by a person skilled in the art, those that are substantially the same, and those that are within the so-called equivalent range. Furthermore, the components disclosed in the embodiment can be combined as appropriate.

[0011] Fig. 1 is a side view of an in-vehicle device according to this embodiment when installed horizontally. Fig. 2 is a side view of an in-vehicle device according to this embodiment when installed vertically. Fig. 3 is an external perspective view of a main body of the in-vehicle device according to this embodiment. As shown in Figs. 1 and 2, the in-vehicle device 10 according to this embodiment is, for example, a navigation system or an audio system installed on a dashboard D of a vehicle. The in-vehicle device 10 has a main body 20 and a display 30.

[0012] In this embodiment, the main body 20 is formed to a 1DIN (Deutsch Industrie Norm) size, for example, 50 mm in height and 180 mm in width according to the German Industrial Standards. However, the size of the main body 20 is not limited to this. To improve mountability in a vehicle, the in-vehicle device 10 can be installed in multiple configurations with different orientations of the main body 20 relative to the vehicle. Specifically, the in-vehicle device 10 can be installed with the main body 20 in a horizontal orientation as shown in FIG. 1 or a vertical orientation as shown in FIG. 2. In this specification, as shown in FIG. 1, the side to which the display unit 30 is connected when the main body 20 is installed horizontally is defined as the front side, and the vertical and horizontal directions refer to the directions when viewed from this front side.

[0013] As shown in FIG. 3 , the main body 20 includes a housing 21 and a front panel 22. The housing 21 is a substantially rectangular parallelepiped box made of sheet metal with an open front, and the front panel 22 is a synthetic resin fitting plate installed on the front side of the housing 21. The housing 21 includes a top panel 21a, a bottom panel 21b, side panels 21c and 21d, and a rear panel 21e. The housing 21 also includes a rectangular window 23 in the top panel 21a. In this embodiment, the top panel 21a is the opening surface of the window 23. As shown in FIGS. 1 and 2 , the housing 21 houses a gyro sensor unit (detection unit) 40 including a sensor board (detection board) 41 including a gyro sensor 41a (detection unit, FIG. 5 ). A portion of the gyro sensor unit 40 is exposed through the window 23 ( FIG. 3 ).

[0014] When the main body 20 is installed horizontally, as shown in FIG. 1 , the lower panel 21b of the housing 21 faces the vehicle floor (not shown). In the example of FIG. 1 (so-called DIN installation), the angle θ formed between the lower panel 21b of the housing 21 and the horizontal plane H of the vehicle when the main body 20 is installed horizontally is 20°. This angle θ is not limited to this and may be changed, for example, within a range of 0°≦θ≦30° depending on the state of the vehicle's equipment mounting portion. On the other hand, when the main body 20 is installed vertically, as shown in FIG. 2 , the rear panel 21e of the housing 21 faces the vehicle floor (not shown). In the example of FIG. 2 (so-called separate installation), the angle θ formed between the lower panel 21b of the housing 21 and the horizontal plane H of the vehicle when the main body 20 is installed vertically is 90°. This angle θ is also not limited to this and may be changed, for example, within a range of 85°≦θ≦95°.

[0015] As shown in FIGS. 1 and 2 , the display unit 30 includes a display unit 31, a display support unit 32, and a display fixing unit 33. The display unit 31 is a touch panel display equipped with a screen for displaying information and an operation unit for a user to input information. The display unit 31 is larger than the 1DIN size of the main body 20, e.g., a 10-inch display screen. The display support unit 32 is configured as a frame that supports the display unit 31, and the display support unit 32 and the display fixing unit 33 are connected via a pivot shaft (not shown). When the main body 20 is installed horizontally, as shown in FIG. 1 , the display fixing unit 33 is fixed to the front panel 22 of the main body 20. When the main body 20 is installed vertically, as shown in FIG. 2 , the display fixing unit 33 and the front panel 22 of the main body 20 are electrically connected by a connection cable 15.

[0016] Next, the gyro sensor unit 40 will be described. FIG. 4 is an external perspective view of the gyro sensor unit. FIG. 5 is an exploded perspective view of the gyro sensor unit. FIG. 6 is a cross-sectional view taken along line A-A in FIG. 3, showing the positional relationship of the sensor board when the main body is installed horizontally. FIG. 7 is a cross-sectional view taken along line A-A in FIG. 3, showing the positional relationship of the sensor board when the main body is installed vertically. FIG. 8 is a cross-sectional view taken along line B-B in FIG. 3, showing the positioning engagement portion when the main body is installed horizontally. FIG. 9 is a cross-sectional view taken along line B-B in FIG. 3, showing the positioning engagement portion when the main body is installed vertically.

[0017] As shown in FIGS. 4 to 7 , the gyro sensor unit 40 is fixed to the inner surface of the top plate 21 a of the housing 21, and the position (posture) of the sensor board 41 can be adjusted depending on the orientation of the housing 21 (main body 20), whether the housing 21 is installed horizontally or vertically with respect to the vehicle. In this embodiment, when the main body 20 is installed horizontally, the sensor board 41 is positioned at a first position along the top plate 21 a of the housing 21 (the opening surface of the window portion) as shown in FIG. 6 . Here, “along the top plate 21 a” not only refers to the sensor board 41 and the top plate 21 a being parallel to each other, but also refers to the case where, when the main body 20 is installed horizontally, the inclination angle of the sensor board 41 relative to the top plate 21 a is equal to or less than the angle θ formed between the bottom plate 21 b of the housing 21 and the horizontal plane H of the vehicle. That is, as shown in FIG. 1 , the first position of the sensor board 41 when the main body 20 is installed horizontally refers to the position where the sensor board 41 is approximately parallel to the horizontal plane H of the vehicle.

[0018] Furthermore, when the main body 20 is installed vertically, the sensor board 41 is located at a second position in a direction intersecting with the top plate 21a (opening surface of the window portion) of the housing 21, as shown in Fig. 7. This "along a direction intersecting with the top plate 21a" does not only exclude a state in which the sensor board 41 and the top plate 21a are arranged parallel to each other, but also refers to a state in which, when the main body 20 is installed vertically, the inclination angle of the sensor board 41 with respect to the top plate 21a is equal to or less than the angle θ formed between the bottom plate 21b of the housing 21 and the horizontal plane H of the vehicle. In other words, as shown in Fig. 2, the second position of the sensor board 41 when the main body 20 is installed vertically also refers to a position in which the sensor board 41 is approximately parallel to the horizontal plane H of the vehicle.

[0019] 5, the gyro sensor unit 40 includes a sensor board 41, a sensor board support member (detection board support member) 50, a first base 60, and a second base 70. The sensor board support member 50, the first base 60, and the second base 70 are each integrally manufactured from a synthetic resin material.

[0020] The sensor board 41 is a board on which a gyro sensor 41a is mounted, and is connected to a flexible flat cable 41b for communication with other boards (not shown) housed in the main body 20 or the display unit 30. The gyro sensor 41a is a sensor that detects the angular velocity of the vehicle in three axial directions (roll, pitch, and yaw), and detects the attitude of the vehicle on which the main body 20 is installed based on the angular velocity signals in each direction. Therefore, in order to accurately detect the attitude of the vehicle, the gyro sensor unit 40 is capable of appropriately adjusting the position (attitude) of the sensor board 41 in accordance with the orientation of the housing 21 (main body 20) installed relative to the vehicle.

[0021] The sensor board support member 50 includes a support portion 51 that supports the sensor board 41 and a pair of sliding portions 52, 52 formed on both ends of the support portion 51. As shown in FIGS. 6 and 7 , the support portion 51 is a member formed in a substantially semi-cylindrical shape, and the sensor board 41 is fixed to its inner circumferential surface 51a with screws 45. The outer circumferential surface 51b of the support portion 51 is exposed to the outside of the housing 21 through a window 23 opened in the top plate 21a of the housing 21. The outer circumferential surface 51b is provided with a plurality of (two in this embodiment) ridges (protrusions) 53 that protrude from the outer circumferential surface 51b and extend in the axial direction of the semi-cylinder. These ridges 53 function as protrusions for fingers to hook when sliding the sensor board support member 50 (sensor board 41) relative to the first base portion 60 and the second base portion 70.

[0022] The sliding portion 52 is formed in a partially cylindrical shape, is sandwiched between a guide rail 46 (described later) formed between the first base portion 60 and the second base portion 70, and slides along the guide rail 46. A recess 56 recessed in the radial direction is provided on the outer circumferential surface of this partially cylindrical sliding portion 52, as shown in Figures 8 and 9 .

[0023] When assembled together, the first base 60 and the second base 70 sandwich the sensor board support member 50 and slidably support the sensor board support member 50. As shown in FIG. 5 , the first base 60 is disposed on the inner surface of the top plate 21a of the housing 21, straddling the window 23, and is fixed by screws. The method of fixing the first base 60 is not limited to screwing, and any existing fixing method may be used, or a portion corresponding to the first base may be integrally molded on the inner surface of the top plate 21a. The first base 60 has a pair of left and right outer guide rails 61, 61 disposed along both edges of the window 23, and multiple screw receiving portions 62 for fixing the second base 70. The outer guide rail 61 has an inner circumferential surface (guide surface) 61a formed in an arc shape. The second base 70 is fixed to the screw receiving portions 62 of the first base 60 with the screws 45, with the sensor board support member 50 interposed therebetween. As shown in Figures 8 and 9, the second base 70 has a pair of left and right inner guide rails 71, 71 arranged opposite the outer guide rail 61 with a predetermined gap between them, and an opening 72 penetrating the second base 70. The inner guide rail 71 has an outer peripheral surface (guide surface) 71a formed in an arc shape. The opening 72 is formed at a position where the flexible flat cable 41b connected to the sensor board 41 passes through.

[0024] The inner peripheral surface 61a of the outer guide rail 61 and the outer peripheral surface 71a of the inner guide rail 71 are each formed in the shape of a concentric arc with different diameters, and the outer guide rail 61 and the inner guide rail 71 slidably support the sliding portion 52 of the sensor board support member 50 by sandwiching it between the inner peripheral surface 61a of the outer guide rail 61 and the outer peripheral surface 71a of the inner guide rail 71. In this embodiment, the guide rail 46 is configured to include the outer guide rail 61 and the inner guide rail 71.

[0025] The outer guide rail 61 also forms a portion of the inner peripheral surface 61a and has at least two cantilevered arms 63. The tips of the arms 63 each have a protrusion 64 that protrudes from the inner peripheral surface 61a. When the sensor board 41 ( FIGS. 6 and 7 ) is positioned at the first or second position, the protrusion 64 fits into a recess 56 formed on the outer peripheral surface of the sliding part 52, thereby positioning the sensor board 41. Specifically, when the sliding part 52 (sensor board support member 50) is moved along the inner peripheral surface 61a of the outer guide rail 61, the sliding part 52 abuts against the protrusion 64 formed on the tip of the arm 63, and the arm 63 deforms in a direction away from the sliding part 52, causing the sliding part 52 to move while avoiding the protrusion 64. When the recess 56 formed on the sliding part 52 reaches the protrusion 64, the protrusion 64 fits into the recess 56, and the deformation of the arm 63 is restored. This allows the sensor board 41 to be positioned at the first position or the second position. Furthermore, because the arm 63 elastically deforms and the convex portion 64 fits into the concave portion 56, a clicking sensation is felt when the sensor board 41 (sensor board support member 50) is moved, allowing the user to easily understand that the sensor board 41 has been positioned at the first position or the second position. In this embodiment, the positioning engagement portion is composed of the convex portion 64 of the outer guide rail 61 and the concave portion 56 of the sliding portion 52.

[0026] Furthermore, a pressing surface 73 that presses the sliding portion 52 toward the convex portion 64 is formed on the outer peripheral surface 71a of the inner guide rail 71 at a position facing the convex portion 64 of the outer guide rail 61 with the sliding portion 52 in between. This pressing surface 73 is formed as part of the outer peripheral surface 71a of the inner guide rail 71. Therefore, when the concave portion 56 of the sliding portion 52 is fitted into the convex portion 64 of the outer guide rail 61, the pressing surface 73 of the inner guide rail 71 presses the sliding portion 52, so that even if, for example, vibration of the vehicle occurs, the concave portion 56 of the sliding portion 52 can be prevented from coming off the convex portion 64 of the outer guide rail 61.

[0027] Next, the identification markings will be described. Fig. 10 is a partially enlarged view showing the identification markings exposed in the window when the main body is installed horizontally. Fig. 11 is a partially enlarged view showing the identification markings exposed in the window when the main body is installed vertically. In the above-described configuration, the sensor board support member 50 (sensor board 41) can be positioned in a position (posture) corresponding to the orientation in which the main body 20 is installed by operating the protrusion 53 exposed in the window 23 opened in the top panel 21a of the housing 21 through the window 23. In this case, it is preferable that the sensor board 41 be able to visually identify whether the main body 20 is positioned horizontally or vertically.

[0028] For this reason, in this embodiment, as shown in FIGS. 10 and 11 , an identification mark 80 indicating the orientation in which the main body unit 20 should be installed is provided on the outer peripheral surface 51 b of the support portion 51 of the sensor board support member 50 exposed in the window portion 23. Specifically, the identification mark 80 indicates whether the main body unit 20 should be installed horizontally or vertically. In the example of FIG. 10 , the character string "HORIZONTAL" is provided on the outer peripheral surface 51 b of the support portion 51 as the identification mark 80 for installing the main body unit 20 horizontally. In the example of FIG. 11 , the character string "VERTICAL" is provided on the outer peripheral surface 51 b of the support portion 51 as the identification mark 80 for installing the main body unit 20 vertically. Because these identification marks 80 are exposed in the window portion 23, it is possible to visually easily identify which installation orientation of the main body unit 20 the sensor board 41 is positioned in.

[0029] The character strings of the identification marks 80 can be applied to the outer peripheral surface 51b of the support portion 51 by printing, for example, or by engraving. The above-described identification marks 80 may be distinguished by colors corresponding to the installation direction, rather than by character strings. This configuration allows the sensor board support member 50 to simultaneously fulfill both its external design and its movement (rotation) mechanism functions.

[0030] As described above, the in-vehicle device 10 according to this embodiment includes the display unit 30 and the main body unit 20 connected to the display unit 30, and is configured to be installable in a plurality of modes with different orientations of the main body unit 20 relative to the vehicle. The main body unit 20 has a housing 21 with a window 23 opening in an upper surface 21a, and a gyro sensor unit 40 housed in the housing 21. The gyro sensor unit 40 has a pair of guide rails 46 with an inner peripheral surface 61a and an outer peripheral surface 71a formed in an arc shape, and a pair of guide rails 46 formed in a semi-cylindrical shape with the window 23 on the outer peripheral surface 51b. The sensor board support member 50 has a support portion 51 having a protrusion portion 53 exposed to the outside of the housing 21 through the protrusion portion 53, and supporting a sensor board 41 including a gyro sensor 41a on an inner surface 51a, and a pair of sliding portions 52 formed on both ends of the support portion 51 and capable of sliding on the guide rails 46, and the sensor board support member 50 can be moved via the protrusion portion 53 to be displaced between a first position where the sensor board 41 is arranged along the top plate 21a of the housing 21 and a second position where the sensor board 41 is arranged along a direction perpendicular to the top plate 21a of the housing 21.

[0031] This configuration allows the orientation of the sensor board 41, including the gyro sensor 41a, to be easily adjusted to match the installation orientation of the main body 20 when the main body 20 is installed horizontally or vertically. Therefore, a single sensor board 41 can accommodate both horizontal and vertical installation. Furthermore, the sensor board support member 50 (sensor board 41) can be moved via the protrusion 53 exposed through the window 23 of the housing 21, allowing the end user to adjust the orientation of the sensor board 41 before installing it in the vehicle. This configuration also eliminates the need for a software-based control system, allowing free capacity, such as ICs, to be used elsewhere. Furthermore, this configuration requires only one sensor board 41, reducing the calibration man-hours by half compared to a configuration using two sensor boards.

[0032] In the in-vehicle device 10 according to this embodiment, the gyro sensor unit 40 includes a convex portion 64 and a concave portion 56 as positioning engagement portions that position the sensor board 41 at the first position and the second position, respectively, by engaging the guide rail 46 with the sliding portion 52. According to this configuration, by engaging the convex portion 64 of the guide rail 46 with the concave portion 56 of the sliding portion 52, the sensor board 41 can be easily positioned at the first position and the second position, respectively.

[0033] In the in-vehicle device 10 according to this embodiment, the outer guide rail 61 forms a part of the inner peripheral surface 61 a and has at least two cantilevered arms 63, and the tips of these arms 63 have convex portions 64 that protrude from the inner peripheral surface 61 a and fit into concave portions 56 formed in the sliding portion 52 when the sensor board 41 is positioned at the first position or the second position. This provides a clicking sensation when the sensor board 41 (sensor board support member 50) is moved, allowing the user to easily understand that the sensor board 41 has been positioned at the first position or the second position. Furthermore, the above-described arms 63 elastically deform, allowing the convex portions 64 of the arms 63 to fit into the concave portions 56 of the sliding portion 52, thereby realizing positioning and the clicking sensation. This eliminates the need for additional fixing members such as screws or elastic members such as springs for positioning, thereby simplifying the device configuration.

[0034] In the in-vehicle device 10 according to this embodiment, the gyro sensor unit 40 includes a pressing surface 73 that presses the sliding portion 52 toward the convex portion 64 at least at a position facing the convex portion 64 across the sliding portion 52, so that the pressing surface 73 of the inner guide rail 71 can press the sliding portion 52 when the concave portion 56 of the sliding portion 52 is fitted into the convex portion 64 of the outer guide rail 61. Therefore, even if vibrations or the like occur in the vehicle, for example, the concave portion 56 of the sliding portion 52 can be prevented from coming off the convex portion 64 of the outer guide rail 61.

[0035] In the in-vehicle device 10 of this embodiment, the outer surface 51b of the support portion 51 of the sensor board support member 50 is provided with an identification marking 80 indicating the direction in which the main body portion 20 is installed, so that it is easy to visually identify which installation direction of the main body portion 20 the sensor board 41 is positioned in.

[0036] Furthermore, in the in-vehicle device 10 of this embodiment, the sensor board support member 50 exposed to the window portion 23 is supported by being sandwiched between the first base portion 60 and the second base portion 70, which prevents the sensor board support member 50 from falling off and also prevents foreign objects such as screws from entering the housing 21 through the window portion 23.

[0037] The above-described embodiment is an example of the present disclosure, and the present disclosure is not limited to the present embodiment. For example, in the present embodiment, the sensor board 41 is positioned at two positions, a first position and a second position, depending on the orientation of the main body 20. However, the sensor board 41 may be positioned at three or more positions so that the angle of the sensor board 41 can be set. In this case, the set angle of the sensor board may be confirmed by printing a ruler-like scale on the outer peripheral surface 51 b of the support portion 51 of the sensor board support member 50 so that the scale can be determined based on its position relative to the end of the window portion 23, or by coloring the outer peripheral surface 51 b in two colors so that the angle can be determined based on the ratio at which the colors are visible.

[0038] In addition, in the present embodiment, the gyro sensor 41a, the sensor board 41, and the gyro sensor unit 40, which respectively detect the posture of an object, are illustrated as examples of the detection unit, detection board, and detection unit according to the present disclosure. However, other configurations including sensors with preferred directions of use (e.g., a motion sensor or a proximity sensor) may also be used. Furthermore, the detection unit is not limited to a sensor, but may be, for example, a communication antenna that detects specific radio waves, such as Bluetooth (registered trademark) or Wi-Fi (registered trademark). This type of communication antenna tends to transmit radio waves less easily (communicate more difficultly) when covered with metal than when covered with, for example, a synthetic resin material. Therefore, for example, when the main body is installed horizontally, the sensor board on which the communication antenna is mounted is positioned in a first position along the top panel 21a (opening surface of the window portion) of the housing 21 via a sensor board support member made of synthetic resin. Furthermore, for example, when the main body is installed vertically, the sensor board on which the communication antenna is mounted is positioned in a direction intersecting with the top plate 21a (opening surface of the window) of the housing 21, that is, in a second position where it is arranged along the front panel 22 made of a synthetic resin material of the housing 21. In this way, by adjusting the orientation of the sensor board depending on the orientation in which the main body is installed, it is possible to improve the communication connection status.

[0039] The projection display device of this embodiment can be used, for example, as an in-vehicle device that can be installed in a plurality of configurations with different orientations of the main body relative to the vehicle.
