[Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2008-100622 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the above-mentioned prior art, the display is directly attached to the ceiling of the vehicle interior, which limits the position where the display can be placed and the angle of the display surface relative to the occupants. In other words, the above-mentioned prior art has room for improvement in terms of ensuring the degree of freedom in the position where the display can be placed and the angle of the display surface relative to the occupants.

[0005] SUMMARY OF THE INVENTION In consideration of the above, an object of the present invention is to provide a vehicle display device that can secure a degree of freedom in the position where the display can be placed and in the angle of the display surface relative to the occupant. [Means for solving the problem]

[0006] The vehicle display device of the first aspect comprises a display having a display surface, and an arm portion whose one end is rotatably supported relative to the roof of the vehicle compartment and whose other end rotatably supports the display.

[0007] The vehicle display device according to the first aspect includes a display and an arm, one end of which is rotatably supported on a roof of the vehicle compartment, and the other end of which is rotatably supported on the display.

[0008] Therefore, in this aspect, the position of the display within the vehicle compartment can be changed by rotating the arm portion relative to the roof portion of the vehicle compartment.

[0009] In addition, in this aspect, the orientation of the display surface of the display can be changed by rotating the display relative to the arm portion.

[0010] The vehicle display device of the second aspect is the vehicle display device of the first aspect, wherein the display and the arm portion are capable of taking a storage position in which they are arranged along the roof portion, and in the storage position the display surface faces downward toward the vehicle.

[0011] According to the vehicle display device of the second aspect, the display and the arm can be placed in a storage position along the roof, with the display surface facing downward toward the vehicle.

[0012] Therefore, in this aspect, the occupant in the vehicle can see the display surface of the display while maintaining a certain distance between the occupant and the display.

[0013] The vehicle display device of the third aspect is the vehicle display device of the first or second aspect, further comprising a control unit capable of controlling a first drive unit that rotates the arm portion relative to the roof portion and a second drive unit that drives the display relative to the arm portion, and the control unit is capable of controlling the first drive unit and the second drive unit so that when the first drive unit drives the other end side away from the roof portion, the second drive unit drives so that the area of ​​the display surface when viewed from a direction perpendicular to the rotation axis of the display and along the horizontal direction becomes larger.

[0014] The vehicle display device according to the third aspect includes a first drive unit that rotates the arm portion relative to the roof portion and a second drive unit that drives the display relative to the arm portion, and these are controlled by a control unit.

[0015] In this aspect, the control unit controls the first drive unit and the second drive unit so that when the first drive unit drives the other end side of the arm unit to move away from the roof unit, the second drive unit drives to increase the area of ​​the display surface when viewed from a direction perpendicular to the rotation axis of the display and along the horizontal direction.

[0016] Therefore, in this aspect, the angle of the display surface of the display can be adjusted to an angle that is easy to view for an occupant with their upper body upright, while suppressing interference between the display and the roof portion.

[0017] A fourth aspect of the vehicle display device is the vehicle display device of the third aspect, wherein the control unit is capable of controlling the first drive unit so that the angle of the arm unit relative to the roof unit is a predetermined angle.

[0018] In the vehicle display device according to the fourth aspect, the control unit controls the first drive unit, thereby setting the angle of the arm unit relative to the roof unit to a predetermined angle. Therefore, in this aspect, the display can be positioned closer to the occupant than in a configuration in which the display is directly attached to the roof unit of the vehicle cabin.

[0019] The vehicle display device of the fifth aspect is a vehicle display device of any one of the second aspect, the third aspect which cites the second aspect, and the fourth aspect, in which a roof rail garnish is provided for each of a pair of roof side rails which form the outer part of the roof section in the vehicle width direction, covering the roof side rails from the inside of the vehicle compartment, and a recess is formed in the roof rail garnish into which a part of the arm section fits when in the storage position when viewed from the vertical direction of the vehicle.

[0020] In the vehicle display device according to the fifth aspect, the roof side rails constituting the outer portions of the roof in the vehicle width direction are covered from the inside of the vehicle compartment with a roof rail garnish, and a recess is formed in the roof rail garnish, and this recess is adapted to fit a part of the arm portion in the storage position when viewed from the vertical direction of the vehicle.

[0021] Therefore, in this aspect, the space available for placing the display between the roof rail garnishes can be made larger than in a configuration in which the arm portion in the storage position is positioned inside the roof rail garnish in the vehicle width direction. [Effects of the Invention]

[0022] As described above, the vehicle display device according to the present invention has the excellent effect of ensuring a degree of freedom in the position where the display can be placed and in the angle of the display surface of the display relative to the occupant. [Brief explanation of the drawings]

[0023] [Figure 1]1 is a cross-sectional view (a cross-sectional view showing a state cut along line 1-1 in FIG. 2) that schematically shows the configuration of the interior of a vehicle equipped with the vehicle display device according to the present embodiment. [Figure 2] 1 is a bottom view schematically illustrating a configuration around a roof portion of a vehicle interior in a vehicle equipped with a vehicle display device according to an embodiment of the present invention. [Figure 3] 1 is a block diagram showing an example of a hardware configuration of a vehicle display device according to an embodiment of the present invention; DETAILED DESCRIPTION OF THE INVENTION

[0024] An example of an embodiment of a vehicle display device according to the present invention will be described below with reference to Figures 1 to 3. Note that the arrow FR shown as appropriate in each figure indicates the front side of a "vehicle 12" on which a "vehicle display device 10 (hereinafter referred to as display device 10)" according to this embodiment is mounted, the arrow UP indicates the upper side of the vehicle 12, and the arrow LH indicates the left side of the vehicle 12 in the vehicle width direction.

[0025] First, the general configuration of a vehicle 12 will be described using Figure 1. The vehicle 12 has a vehicle body 16 that constitutes the main portion of a "vehicle compartment 14," and the upper portion of the vehicle body 16 is composed of a "roof portion 18." The lower portion of the vehicle body 16 is composed of a floor portion (not shown).

[0026] The roof portion 18 is provided with a pair of "roof side rails 20" that extend in the vehicle longitudinal direction and the vehicle width direction and are arranged on both sides of the roof portion 18 in the vehicle width direction. Each of the roof side rails 20 is covered from the inside of the passenger compartment 14 by a "roof rail garnish 22."

[0027] 2, a roof window 24 made of a colorless, transparent inorganic glass plate having a certain thickness and extending longitudinally in the vehicle front-to-rear direction is installed between the roof side rails 20. In other words, the roof portion 18 is configured as a so-called panoramic roof.

[0028] A front seat 26 is disposed at the front of the vehicle and a rear seat 28 is disposed at the rear of the front seat 26 in the passenger compartment 14 of the vehicle body 16 configured as described above. Various devices constituting the display device 10 are disposed on the roof portion 18 at the rear of the front seat 26 and in front of the rear seat 28.

[0029] As also shown in FIG. 3, the display device 10 includes a "display 30," a pair of "arm portions 32," and a "control portion 34."

[0030] The display 30 has a rectangular shape in a plan view with its longitudinal direction aligned with the vehicle width direction, and is provided with a "display surface 30A" capable of displaying various information to an occupant (not shown) seated in the rear seat 28. The display 30 is electrically connected to a display control unit (not shown) via wiring (not shown), and is driven by signals output from the display control unit to display various images, messages, and the like on the display surface 30A.

[0031] Furthermore, a "motor gear unit 36" serving as a second drive unit is provided on both sides of the display 30 in the vehicle width direction, on the opposite side of the display surface 30A in the center of the short side. The display 30 is supported on both sides of the vehicle width direction by the roof side rails 20 via arm units 32. The drive of the motor gear unit 36 ​​is controlled by a control unit 34, as will be described later.

[0032] More specifically, the arm section 32 includes an arm main body section 38 that constitutes its main portion, and a "motor gear unit 40" that serves as a first drive section.

[0033] The arm main body 38 includes an arm outer 42 that forms the outer portion of the arm main body 38 in the vehicle width direction, and an arm inner 44 that forms the inner portion of the arm main body 38 in the vehicle width direction, and is hollow inside. A motor gear unit 40 is built into one end 38A of the arm main body 38, and the motor gear unit 40 is connected to a bearing portion (not shown) provided on the inner side of the roof side rail 20. As a result, the one end 38A side of the arm portion 32 is supported so as to be rotatable around the vehicle width direction relative to the roof portion 18. In other words, the extension direction of the rotation axis of the display 30 is the vehicle width direction.

[0034] Furthermore, a "recess 22A" that is recessed outward in the vehicle width direction and is open toward the lower side of the vehicle is formed at the location where the arm portion 32 is attached to the roof rail garnish 22. As will be described later, a part of the arm portion 32 is accommodated in the recess 22A.

[0035] Meanwhile, a bearing (not shown) is built into the "other end 38B" of the arm main body 38, and this bearing is connected to the motor gear unit 36 ​​provided on the display 30. As a result, the arm 32 supports the display 30 on the other end 38B side so that the display 30 can rotate around the vehicle width direction.

[0036] Next, the configuration of the control unit 34 will be described with reference to Fig. 3. The control unit 34 is configured to include a CPU (Central Processing Unit) 34A, a ROM (Read Only Memory) 34B, a RAM (Random Access Memory) 34C, a storage 34D, and an input / output I / F (Interface) 34E. The CPU 34A, ROM 34B, RAM 34C, storage 34D, and input / output I / F 34E are connected to each other via a bus 34F so as to be able to communicate with each other.

[0037] The CPU 34A is a central processing unit that can control various devices by executing various programs. Specifically, the CPU 34A reads programs from the ROM 34B and executes the programs using the RAM 34C as a work area. The CPU 34A reads and executes the execution programs stored in the ROM 34B, enabling the control unit 34 to perform various functions, as will be described later.

[0038] More specifically, the ROM 34B stores various programs and data related to the control of the motor gear unit 36 ​​and the motor gear unit 40. On the other hand, the RAM 34C can temporarily store programs or data as a work area.

[0039] The storage 34D includes a hard disk drive (HDD) or a solid state drive (SSD), and is capable of storing various programs including an operating system and various data.

[0040] The input / output I / F 34E is an interface that enables the control unit 34 to communicate with various devices mounted on the vehicle 12. The control unit 34 is connected to each device described below via the input / output I / F 34E so that they can communicate with each other.

[0041] Specifically, the devices connected to the control unit 34 include an operation unit 46 used to operate the display device 10, a motor driver 48 that drives the motor gear unit 36, a motor driver 50 that drives the motor gear unit 40, an ottoman control unit 52 that drives the drive unit of an ottoman (not shown) provided in the rear seat 28, and a seatback control unit 54 that drives the drive unit (not shown) that rotates the seatback 28A of the rear seat 28.

[0042] The control unit 34 controls the motor driver 48 and the motor driver 50 based on the operation signal output from the operation unit 46 when the occupant sitting in the rear seat 28 operates the operation unit 46, and is able to move the display 30 and the arm unit 32 to the position desired by the occupant.

[0043] Specifically, the control unit 34 controls the motor driver 48 and the motor driver 50 so that when the occupant normally operates the motor gear unit 40 using the operating unit 46 and the arm unit 32 rotates, the display 30 rotates in conjunction with the arm unit 32.

[0044] More specifically, in the normal state (initial position), the display 30 and the arm portion 32 are in a retracted position where they are arranged along the roof portion 18. At this time, the display surface 30A of the display 30 faces downward of the vehicle.

[0045] In this state, the arm portion 32 is in a state where a major portion thereof is accommodated in a recess 22A formed in the roof rail garnish 22 when viewed from the top-bottom direction of the vehicle, as shown in FIG.

[0046] The control unit 34 controls the motor gear unit 36 ​​and the motor gear unit 40 via the motor driver 48 and the motor driver 50 so that when the arm unit 32 rotates from a state in which the display 30 and the arm unit 32 are in the storage position so that the other end 38A of the arm unit 32 moves away from the roof unit 18, the area of ​​the display surface 30A of the display 30 as seen from the rear seat 28 side in the fore-and-aft direction of the vehicle becomes larger.

[0047] In the following description, the state in which the display 30 and the arm unit 32 are arranged along the vertical direction of the vehicle will be referred to as the fully deployed position of the display 30 and the arm unit 32. Also, the state in which the arm unit 32 is positioned between the stored position and the fully deployed position will be referred to as the semi-deployed position of the display 30 and the arm unit 32.

[0048] In addition, in this embodiment, when the display 30 and arm portion 32 move from the fully deployed position or the semi-deployed position to the stored position during normal operation by the occupant, the control unit 34 controls the motor gear unit 36 ​​and the motor gear unit 40 so that the area of ​​the display surface 30A of the display 30 as seen from the rear seat 28 side in the fore-and-aft direction of the vehicle becomes smaller when the arm portion 32 rotates so that the other end 38A of the arm portion 32 approaches the roof portion 18.

[0049] Furthermore, in this embodiment, the occupant can perform an adjustment operation on the operation unit 46, thereby allowing the display 30 and the arm unit 32 to rotate independently.

[0050] In addition, in this embodiment, the control unit 34 controls the ottoman control unit 52 and the seat back control unit 54 based on the occupant's operation of the operating unit 46, thereby enabling the ottoman and seat back 28A to be driven to the state desired by the occupant.

[0051] In this embodiment, the display 30 and the arm portion 32 are rotated to a predetermined state in conjunction with the driving of the ottoman and the seat back 28A.

[0052] (Actions and Effects of This Embodiment) Next, the operation and effects of this embodiment will be described.

[0053] 1 and 2, this embodiment includes a display 30 and an arm portion 32, and one end 38A of the arm portion 32 is rotatably supported with respect to the roof portion 18 of the vehicle interior 14. The other end 38B of the arm portion 32 rotatably supports the display 30.

[0054] Therefore, in this embodiment, the position of the display 30 within the vehicle interior 14 can be changed by rotating the arm portion 32 relative to the roof portion 18 of the vehicle interior 14.

[0055] In this embodiment, the display 30 can be rotated relative to the arm portion 32 to change the orientation of the display surface 30A of the display 30.

[0056] In this embodiment, the display 30 and the arm portion 32 can be placed in a storage position so as to be aligned with the roof portion 18. In this state, the display surface 30A of the display 30 faces downward toward the vehicle.

[0057] Therefore, in this embodiment, the occupant in the vehicle interior 14 can view the display surface 30A of the display 30 while the distance between the occupant and the display 30 is secured.

[0058] In addition, this embodiment is provided with a motor gear unit 40 that rotates the arm portion 32 relative to the roof portion 18 and a motor gear unit 36 ​​that drives the display 30 relative to the arm portion, and these are controlled by the control unit 34.

[0059] In this embodiment, the control unit 34 controls the motor gear unit 36 ​​and the motor gear unit 40 so that when the motor gear unit 40 drives so that the other end 38B of the arm portion 32 moves away from the roof portion 18, the motor gear unit 36 ​​drives so that the area of ​​the display surface 30A of the display 30 increases when viewed from a direction perpendicular to the rotation axis of the display 30 and along the horizontal direction.

[0060] Therefore, in this embodiment, the angle of the display surface 30A of the display 30 can be adjusted to an angle that is easy to view for an occupant with their upper body upright, while suppressing interference between the display 30 and the roof portion 18.

[0061] Furthermore, in this embodiment, the motor gear unit 40 is controlled by the control unit 34, so that the angle of the arm unit 32 relative to the roof unit 18 can be set to a predetermined angle. Therefore, in this embodiment, the display 30 can be positioned closer to the occupant than in a configuration in which the display 30 is directly attached to the roof unit 18 of the vehicle interior 14.

[0062] Additionally, in this embodiment, the roof side rails 20 that form the outer portions of the roof portion 18 in the vehicle width direction are covered with a roof rail garnish 22 from the inside of the passenger compartment 14. The roof rail garnish 22 is formed with a recess 22A that fits into a portion of the arm portion 32 in the storage position when viewed from the vertical direction of the vehicle.

[0063] Therefore, in this embodiment, the space available for placing the display 30 between the roof rail garnishes 22 can be increased compared to a configuration in which the arm portion 32 in the storage position is positioned inside the roof rail garnish 22 in the vehicle width direction.

[0064] As described above, the display device 10 according to this embodiment can ensure a degree of freedom in the position where the display 30 can be placed and the angle of the display surface 30A of the display 30 relative to the occupant.

[0065] In the above-described embodiment, the display surface 30A was provided on the surface of the display 30 that is on the lower side of the vehicle when the display 30 is in the stored state, but the display surface 30A may also be provided on the surface of the display 30 that is on the upper side of the vehicle when the display 30 is in the stored state.

[0066] With this configuration, when the display 30 is in the stored state, messages and the like displayed on the display surface 30A on the upper side of the vehicle can be viewed from outside the vehicle through the roof window 24. Also, when the display 30 is in the stored state, the display surface 30A on the upper side of the vehicle can be made to emit light, thereby enabling the display 30 to be used as lighting for the outside of the vehicle. Furthermore, when the display 30 and the arm portion 32 are in the fully deployed position or the half-deployed position, various images, messages and the like can be displayed on the front seat 26 side using the display surface 30A on the front side of the vehicle.
