Description

Technical Field

[0001] This invention relates to a vehicle display device installed on the surface of the headliner inside a vehicle. Background Technology

[0002] As such devices, there are conventionally known devices that have a bracket installed in the ceiling of a carriage and a display body having a base supported by the bracket. Such a device is described, for example, in Patent Document 1. In the device described in Patent Document 1, the front and rear ends of the bracket are respectively fastened to a pair of front and rear frames provided in the ceiling by bolts.

[0003] However, sometimes the height of the ceiling frame is off, making it difficult to accurately form the mounting surface for the bracket. Therefore, as described in Patent Document 1, if the front and rear ends of the bracket are fastened to the front and rear frames respectively with bolts, adjustments for mounting the bracket are required, making installation difficult.

[0028] The following is for reference Figures 1 to 10G An embodiment of the present invention will be described. The vehicle display device of this embodiment is configured to be installed in the central portion of the roof section (roof surface) in the vehicle width direction, providing various images to rear-seat occupants.

[0029] Figure 1 This is an exploded perspective view of a vehicle display device 100 according to an embodiment of the present invention. Figure 2 This is a perspective view showing the installation state of the vehicle display device 100. For convenience, the following description uses the installation state of the vehicle display device 100 as a reference, and defines the front-to-back direction (length direction), left-to-right direction (width direction), and up-down direction (height direction) as shown in the figure, and explains the structure of each part according to these definitions. Figure 1 , Figure 2 These are images of the vehicle display device 100 viewed from the right rear and above.

[0030] like Figure 2 As shown, the roof section 1 of the vehicle has a roof panel 4, which is a thin metal sheet that extends to cover the outer surface of the vehicle and is generally rectangular in shape when viewed from above, and a roof liner 5, which extends downwards and inwards towards the passenger compartment from below the roof panel 4 and opposite to the roof panel 4. The roof liner 5 is an interior material made of resin or the like, and it is easy to make openings of a specified shape from the inside of the passenger compartment using tools such as knives. A pair of front and rear frames 2 are mounted between the roof panel 4 and the roof liner 5 in the left-right direction, with a specified distance between them in the front-rear direction. It should be noted that the front frame 2 is sometimes referred to as the front frame 2A, and the rear frame 2 as the rear frame 2B.

[0031] Frame 2 is an arched strength member erected from the right to the left end of the roof section 1 near the upper end of the central pillar (not shown), and is integrally formed with the roof panel 4. Specifically, it is bonded to the roof panel 4 using an adhesive such as mastic sealant. It should be noted that... Figure 1 , Figure 2 For convenience, the structure of the frame 2, etc., is shown with the view through the ceiling 1.

[0032] like Figure 1 , Figure 2As shown, the vehicle display device 100 includes: a main bracket 10 supported by a frame 2 of the vehicle's roof section 1; a display body 20 mounted on the main bracket 10; a spacer 30 sandwiched between the roof section 1 (roof liner 5) and the display body 20; and a sub-bracket 40 sandwiched between the rear frame 2B and the main bracket 10. Figure 2 As shown, an opening 5a with a shape approximately the same as that of the main bracket 10 is opened in the roof liner 5, and the main bracket 10 is installed on the frame 2 from the inside of the car body through the opening 5a.

[0033] like Figure 1 As shown, a roughly rectangular opening 200 is provided in the center of the front frame 2A in the left-right direction, and the front end of the main bracket 10 is mounted by covering the opening 200. It should be noted that the opening 200 can also be used to guide cables, wire harnesses, etc. connected to the display body 20 to the top of the front frame 2A.

[0034] The main bracket 10 is constructed of a metal plate component extending in a generally horizontal direction. A support bar 11 is provided at the front end of the main bracket 10. A pair of through holes 11a are formed in the support bar 11, and bolts passing through the through holes 11a are inserted into them. Figure 8 The bolt 201a) is threaded into the threaded hole 201 around the opening 200 of the front frame 2A, thereby fixing the support bar 11 to the front frame 2A. A cover 31 is installed from below on the support bar 11 in a manner that covers the entire support bar 11.

[0035] Multiple threaded holes 13 are provided in the main bracket 10. Specifically, three threaded holes 13 are provided at each of the left and right ends of the main bracket 10 in the front-to-back direction. Screws passing through the display body 20 are threaded into the threaded holes 13, thereby fixing the display body 20 to the main bracket 10. Upwardly curved portions 14 are provided at the middle of the front-to-back direction at both ends of the main bracket 10 in the left and right directions. Upwardly curved portions 15 are also provided at the rear ends of both ends of the main bracket 10 in the left and right directions. Sub-brackets 40 are installed on the curved portions 15 as described later.

[0036] The display body 20 has a base portion 21 that is generally rectangular when viewed from above, and a display 22 that is rotatably supported on the front end of the base portion 21 in the front-back or up-down direction by a hinge extending in the left-right direction. The base portion 21 has a housing made of resin material or the like, and various electronic components are arranged inside the housing. The base portion 21 is formed to be wider than the main bracket 10 in the left-right direction.

[0037] Figure 3 This is a top view (viewed from above) showing the external shape of the display body 20, and in particular the structure of the upper surface of the base portion 21. (See diagram below.) Figure 1 , Figure 3As shown, a rectangular frame-shaped light guide plate 23, which is part of the base portion 21, is installed on the periphery of the base portion 21, and a mounting portion 20a of a spacer 30 is provided along the inner periphery of the light guide plate 23. Figure 3 This is the state before the spacer 30 is installed. The spacer 30 is shorter than the display body 20 in both the front-to-back and left-to-right directions (total length). Therefore, the spacer 30 is installed on the mounting portion 20a provided on the upper surface of the display body 20 without protruding outwards from the display body 20 when viewed from above. A through hole 24 is provided in the base portion 21, corresponding to the threaded hole 13 of the main bracket 10, and the display body 20 is fixed to the main bracket 10 by bolts passing through the through hole 24 and threadedly engaging with the threaded hole 13. Figure 1 As shown, the spacer 30 is configured as a roughly rectangular frame. The spacer 30 is made of an elastic rubber material or the like.

[0038] Figure 4 This is a perspective view showing the main components of the display body 20 with the spacer 30 installed. (See image below.) Figure 4 As shown, a pair of hooks 26 are fixedly mounted on the upper surface of the base portion 21, protruding upwards and forwards. The hooks 26 are connected to the curved portion 14 of the main bracket 10. Figure 1 The positions of the hooks and bends are correspondingly arranged. Therefore, after the main bracket 10 is fixed to the frame 2, and before the monitor body 20 is fixed to the main bracket 10, the hook 26 can engage with the bend 14 to suspend the monitor body 20 on the ceiling 1. That is, the monitor body 20 can be temporarily held in place. Therefore, the installation of the monitor body 20 becomes easier.

[0039] This embodiment is characterized in the construction of the support portion at the rear end of the main bracket 10, namely, in such a way as Figure 1 The main bracket 10 shown is characterized by being supported on the rear frame 2B by a pair of left and right sub-brackets 40. This will be explained below. The sub-brackets 40 are fixed to the rear frame 2B by fastening brackets 50. The fastening brackets 50 are located at two of the multiple slots 202 provided in the left-right direction on the rear frame 2B.

[0040] Figure 5A This is a perspective view showing the overall structure of the fastening bracket 50. Figure 5B It is a side view. Figure 6 This is a perspective view (viewed from a slightly below-the-head angle) showing the installation state of the fastening bracket 50 towards the rear frame 2B. It should be noted that... Figure 5A , Figure 5B In, with Figure 6 Correspondingly, the front-to-back, left-to-right, and up-down directions of the fastening bracket 50 are shown. For example... Figure 5A , Figure 5BAs shown, the fastening bracket 50 is formed by bending a flat plate into a roughly L-shape, having a horizontally extending, roughly rectangular cross plate portion 51 in top view and a roughly rectangular longitudinal plate portion 52 in side view extending downward from the end of the cross plate portion 51 (left end in the figure). A nut 53 engages with the center of the upper surface of the cross plate portion 51. A through hole 51a, larger in diameter than the threaded hole 53a, is coaxially formed in the cross plate portion 51 and the threaded hole 53a of the nut 53.

[0041] like Figure 6 As shown, the longitudinal length of the horizontal plate portion 51 is longer than the longitudinal length of the slot 202 of the rear frame 2B, and the horizontal plate portion 51 is arranged above the slot 202 in a manner that intersects with the slot 202. The longitudinal length of the vertical plate portion 52, especially the longitudinal length of the upper end of the vertical plate portion 52, is equal to or slightly shorter than the longitudinal length of the slot 202. Therefore, the bolt 55 passes through the through hole 51a from below the horizontal plate portion 51. Figure 5B ) and the threaded hole 53a of nut 53 ( Figure 5B When the threads are engaged, the side surface 52a of the longitudinal plate portion 52 abuts against the edge of the slot 202, preventing the fastening bracket 50 from rotating around the threaded hole 53a.

[0042] The longitudinal length of the horizontal plate portion 51 is shorter than the lateral length of the slot 202. Therefore, it is possible to move the horizontal plate portion 51 from... Figure 6 With the horizontal plate portion 51 rotated 90° in one direction around the threaded hole 53a and tilted vertically, it is guided through the slot 202 from below the rear frame 2B to above the rear frame 2B. Then, the horizontal plate portion 51 is restored to its original vertical tilt, and then rotated 90° around the threaded hole 53a, thus becoming... Figure 6 The state.

[0043] Figure 7A This is a perspective view showing the overall structure of the sub-bracket 40, especially the sub-bracket 40 on the right side. Figure 7B It is a top view ( Figure 7A (View from direction B) Figure 7C It is a side view. Figure 7A (View from direction C). The left and right sub-brackets 40 are identical in shape when... Figure 7A When the sub-bracket 40 rotates 180° around the virtual axis in the downward direction, it becomes the sub-bracket 40 on the left.

[0044] like Figures 7A to 7CAs shown, the sub-bracket 40 is constructed from a metal plate member and is symmetrical about the baseline LN of the vertical plane at the midpoint of the front-rear direction. More specifically, the sub-bracket 40 is constructed by bending a plate of a predetermined shape into approximately right angles. The sub-bracket 40 has a horizontal plate portion 41 extending in a generally horizontal direction and a vertical plate portion 42 extending downward from the right end of the horizontal plate portion 41. The horizontal plate portion 41 is approximately rectangular in plan view, and the vertical plate portion 42 is approximately rectangular in side view. The horizontal plate portion 41 protrudes beyond the vertical plate portion 42 in the front-rear direction. It should be noted that a downwardly bent portion 43 is provided at the left end of the horizontal plate portion 41.

[0045] Approximately circular through holes 44 and 45, penetrating the horizontal plate 41 in the vertical direction, are provided at both ends of the horizontal plate 41 in the front-rear direction. Longer holes 46 and 47, which are longer in the vertical direction, penetrate the vertical plate 42 in the left-right direction, located behind the through holes 44 and in front of the through holes 45. For example... Figure 7A As shown, the upper surface of the transverse plate portion 41 forms a generally flat horizontal surface 41a. The outer end faces of the longitudinal plate portion 42 in the left-right direction ( Figure 7A The right end face (in the middle) forms a roughly flat vertical plane 42a.

[0046] Figure 8 This is a perspective view (viewed from an oblique top) showing the configuration of the mounting portion of the main bracket 10 mounted on the front and rear frames 2. Figure 9 It is shown Figure 8 A perspective view (viewed from a downward angle) showing the configuration of the mounting portion of the right-side sub-bracket 40. Figure 9 As shown, bolt 55 ( Figure 6 A through hole 45 passes through the rear end of the horizontal plate portion 41 of the sub-bracket 40 from below. More specifically, on the horizontal surface 41a of the upper surface of the horizontal plate portion 41... Figure 8 With the rear frame 2B in contact with the bottom surface 203, bolt 55 is inserted. Figure 8 As shown, bolt 55 engages with nut 53 of fastening bracket 50 via thread, thereby fixing right sub-bracket 40 to rear frame 2B. At this time, the bolt does not pass through the front through hole 44. It should be noted that the left sub-bracket 40 is used by rotating the right sub-bracket 40 180°; therefore, bolt 55 passes through the rear through hole 44 of the left sub-bracket 40, but not through the front through hole 45.

[0047] like Figure 9 As shown, a bolt 16 is provided on the right-hand curved portion 15 that rises upward from the right end of the rear end of the main bracket 10. The bolt 16 is integrally formed with the curved portion 15 by welding or the like. The bolt 16 passes through the elongated hole 46 on the front side of the sub-bracket 40, and the nut 17 is as shown. Figure 8As shown, it is threaded into bolt 16 from the right. Thus, the rear end of the main bracket 10 is supported by the rear frame 2B via the sub-bracket 40. At this time, as... Figure 9 As shown, the bolt does not pass through the elongated hole 47. In this way, the main bracket 10 is fixed by the bolt 16 that passes through the elongated hole 46, so the position of the main bracket 10 relative to the sub-bracket 40 in the vertical direction (arrow A direction) can be adjusted.

[0048] Although the illustration is omitted, the curved portion 15 that rises upward from the left end of the rear end of the main bracket 10 ( Figure 1 A bolt 16 protrudes to the left. After passing through the elongated hole 47 in the left-side sub-bracket 40, the top of the bolt engages with a nut 17. Thus, both ends of the main bracket 10 are supported by the rear frame 2B via the sub-bracket 40. With the main bracket 10 fixed to the sub-bracket 40, as... Figure 9 As shown, the rear end of the main bracket 10 is located further forward than the rear frame 2B. Therefore, the main bracket 10 can be made shorter in the front-rear direction.

[0049] Figures 10A-10G This diagram illustrates an example of the installation steps for a vehicle display device 100. When installing the vehicle display device 100, firstly, as follows... Figure 10A As shown, the pair of left and right fastening brackets 50 are inserted from below into the slots 202 of the rear frame 2B. More specifically, after inserting the cross plate portion 51, the fastening brackets 50 are rotated 90° to prevent them from falling down. Then, as... Figure 10B As shown, after the bolt 55 is passed through the through holes 44 and 45 of the sub-bracket 40 from below, the bolt 55 is threaded into the nut 53 of the fastening bracket 50. This mounts the left and right sub-brackets 40 onto the rear frame 2B. At this point, the bolt 55 is loosened. Therefore, the sub-bracket 40 can rotate in the direction of the arrow (left and right) with the bolt 55 as a fulcrum.

[0050] Next, after rotating the sub-bracket 40 outwards in the left and right directions (to avoid it), as follows... Figure 10C As shown, a main bracket 10 is arranged between the left and right sub-brackets 40. Furthermore, the left and right sub-brackets 40 are positioned inwards in the left and right directions ( Figure 10C Rotating in the direction of the arrow, a pair of bolts 16 protruding outwards from the curved portions 15 at both ends of the main bracket 10 pass through the elongated holes 46 and 47 of the sub-bracket 40. This temporarily holds the main bracket 10 in the sub-bracket 40. At this time, the end faces 15a (in the left and right directions of the curved portions 15) are rotated. Figure 9 The vertical surface 42a on the inner side of the longitudinal plate portion 42 of the sub-bracket 40 in the left and right directions. Figure 10B They should be parallel and brought into contact without gaps.

[0051] Next, as Figure 10D As shown, bolt 201a is passed through the through hole 11a of the support bar 11 at the front end of the main bracket 10 from below, and bolt 201a is threaded into the threaded hole 201 provided around the opening 200 of the front frame 2A. Thus, the front end of the main bracket 10 is fixed to the front frame 2A. Next, as... Figure 10E As shown, a tightening force is applied to the bolt 55 passing through the rear end of the sub-bracket 40, thereby fixing the sub-bracket 40 to the rear frame 2B.

[0052] Next, as Figure 10F As shown, the elongated holes 46 and 47 of the sub-bracket 40 are used to pass through. Figure 10C Bolts 16 and nuts 17 are threaded together to fix the left and right ends of the rear end of the main bracket 10 to the sub-bracket 40. At this time, the bolts 16 are staggered along the elongated holes 46 and 47 so that the lower surface of the main bracket 10 is horizontal, thereby adjusting the height (slope) of the main bracket 10 and fixing it to the sub-bracket 40. Next, the cover 31 is installed so that it covers the support strip 11 from below the main bracket 10. Figure 1 Furthermore, the through hole 24 that passes through the base portion 21 of the display body 20 ( Figure 3 The bolts of the main bracket 10 are threaded into the threaded holes 13, such as... Figure 10G As shown, the display body 20 is fixed to the main bracket 10. The installation of the vehicle display device 100 is now complete.

[0053] In this embodiment, elongated holes 46 and 47 are provided in the vertical direction of the longitudinal plate portion 42 of the sub-support 40, so that the bolts 16 protruding from the main support 10 in the horizontal direction can move along the elongated holes 46 and 47. This allows adjustment of the height of the main support 10 relative to the rear frame 2B. As a result, even if there is a deviation in the height of the rear frame 2B (e.g., the height at different positions in the horizontal direction), excessive stress on the frame 2 and the main support 10 can be prevented when using bolts to install the main support 10.

[0054] Furthermore, during the installation of the vehicle display device 100, the left and right sub-brackets 40 are configured such that they can rotate in the left and right directions. Figure 10B Therefore, the main bracket 10 can be installed based on a precise determination of its position in the left-right direction. Furthermore, the sub-bracket 40 is configured to be symmetrical about the reference line LN in the front-back direction. Figure 7AThe design allows for the use of identically shaped sub-brackets 40 on both sides, reducing the number of parts (types of parts). The sub-brackets 40 are elongated in the front-to-back direction, and through holes 44 and 45 for fixing the sub-brackets 40 to the rear frame 2B and elongated holes 46 and 47 for fixing the main bracket 10 to the sub-brackets 40 are separated in the front-to-back direction. This allows the main bracket 10 to be positioned further forward than the rear frame 2B, enabling miniaturization of the main bracket 10 in the front-to-back direction.

[0055] The following effects can be achieved by adopting this implementation method.

[0056] (1) The vehicle display device 100 includes: a main bracket 10 supported by a pair of front and rear frames 2 (front frame 2A, rear frame 2B) extending in the left-right direction from the roof portion 1 of the vehicle; a display body 20 mounted on the main bracket 10; and a sub-bracket 40 sandwiched between the rear frame 2B and the main bracket 10. Figure 1 The sub-bracket 40 has a horizontal plate portion 41 fixed to the rear frame 2B, i.e., a horizontal plate portion 41 with through holes 44 and 45; and a vertical plate portion 42 fixed to the main bracket 10, i.e., a vertical plate portion 42 with elongated holes 46 and 47. Figures 7A to 7C The elongated holes 46 and 47 function as a height adjustment mechanism that can adjust the height of the main bracket 10 relative to the rear frame 2B.

[0057] This structure allows for the absorption of height deviations in the rear frame 2B using elongated holes 46 and 47. Therefore, the main bracket 10 can be installed in a favorable position, and its installation can be performed easily. Furthermore, during installation, the main bracket 10 can be positioned horizontally as desired and supported by the frame 2 without generating excessive stress on the frame 2. This allows for optimal mounting of the display body 20 onto the main bracket 10.

[0058] (2) The longitudinal plate portion 42 of the sub-bracket 40 has an end face 15a that abuts against the outer side of the main bracket 10 in the left-right direction, and a vertical surface 42a that extends in the vertical direction. Figure 9 , Figure 10B The height adjustment mechanism consists of elongated holes 46 and 47, which are arranged vertically along the vertical plane 42a such that bolts 16 protruding from the outer end face 15a of the main bracket 10 in the left-right direction pass through them. Figure 9 Therefore, the height of the main bracket 10 can be adjusted through a simple structure.

[0059] (3) The transverse plate portion 41 of the sub-bracket 40 has a horizontal surface 41a that abuts against the bottom surface 203 of the rear frame 2B and extends in the horizontal direction. Figure 8, Figure 9 Through holes 44 and 45 are provided on the horizontal plane 41a to allow bolts 55 to pass through the bottom surface 203 of the frame 2B after penetration. Figure 8 Therefore, the sub-bracket 40 can be easily and securely fixed to the rear frame 2B.

[0060] (4) The auxiliary brackets 40 are a pair of auxiliary brackets fixed to the left and right ends of the main bracket 10 in the left and right directions. Thus, the left and right ends of the main bracket 10 can be stably supported by the rear frame 2B through the auxiliary brackets 40.

[0061] (5) The left and right sub-brackets 40 form a line symmetrical about the baseline LN of the middle part in the front-rear direction. Figures 7A to 7C Elongated holes 46 and 47 are positioned symmetrically about the baseline LN, and through holes 44 and 45 are positioned symmetrically about the baseline LN. Figures 7A to 7C Therefore, by rotating the asymmetrically shaped sub-bracket 40 in the left-right direction by 180°, sub-brackets 40 with the same structure can be used on both sides of the main bracket 10. As a result, the number of parts can be reduced, and costs can be lowered.

[0062] This embodiment can be modified in various ways. Several modifications will be described below. In the above embodiment, the sub-bracket 40 with a height adjustment mechanism is fixed to the rear frame 2B, which is a pair of front and rear frames. However, the sub-bracket with a height adjustment mechanism can also be fixed to the front frame 2A. That is, the frame to which the sub-bracket is fixed can be either the front frame or the rear frame. Alternatively, the sub-bracket can be fixed to both the front frame and the rear frame.

[0063] In the above embodiment, through holes 44 and 45 are provided in the horizontal plate portion 41 of the sub-bracket 40 as a first fixing part for fixing to the rear frame 2B, and elongated holes 46 and 47 are provided in the vertical plate portion 42 of the sub-bracket 40 as a second fixing part for fixing to the main bracket 10. However, the configuration of the first fixing part and the second fixing part is not limited to the above description. In the above embodiment, elongated holes 46 and 47 are provided in the vertical plate portion 42 (second fixing part) of the sub-bracket 40 as a height adjustment mechanism. However, the configuration of the height adjustment mechanism is not limited to this. A height adjustment mechanism may also be provided in the first fixing part. A height adjustment mechanism may also be provided in both the first fixing part and the second fixing part.

[0064] In the above embodiment, the sub-supports 40 provided on the left and right sides of the main support 10 are made to have the same shape. That is, through holes 44 (first through hole) and through holes 45 (second through hole) are provided at positions symmetrical to each other with respect to the reference line LN of the horizontal plate portion 41, and elongated holes 46 (first elongated hole) and elongated holes 47 (second elongated hole) are provided at positions symmetrical to each other with respect to the reference line LN of the vertical plate portion 42. However, a single through hole and a single elongated hole may also be provided, and the shapes of the left and right sub-supports may be made to be different from each other.

[0065] It is possible to combine the above-described embodiments with one or more variations, and it is also possible to combine the variations with each other.
