[0009] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Dimensions, materials, and other specific values ​​shown in the embodiments are merely examples for facilitating understanding of the invention and, unless otherwise specified, do not limit the present invention. In this specification and drawings, elements having substantially the same functions and configurations are designated by the same reference numerals to avoid redundant explanation, and elements not directly related to the present invention are not shown.

[0010] [1. Overview of automobiles to which display devices are applied] First, an overview of an automobile 10 to which a display device 100 according to an embodiment of the present disclosure is applied will be described with reference to Fig. 1. Fig. 1 is a front view showing an automobile 10 to which a display device 100 according to the present embodiment is applied.

[0011] In the following figures, including FIG. 1, the perpendicularly intersecting X, Y, and Z directions are defined as shown. The X direction indicates the vehicle width direction. The vehicle width direction corresponds to the width direction of the automobile 10. The Y direction indicates the front-rear direction. The front-rear direction is a direction that is substantially perpendicular to the vehicle width direction (X direction) and corresponds to the traveling direction of the automobile 10. The Z direction indicates the vertical direction. The vertical direction is a direction that is substantially perpendicular to both the vehicle width direction (X direction) and the front-rear direction (Y direction).

[0012] As shown in FIG. 1 , the display device 100 according to this embodiment is a portable display device that is detachably attached inside the cabin 12 of an automobile 10. The automobile 10 to which the display device 100 is attached is, for example, an NRS vehicle, a taxi, a bus, or the like. NRS is an abbreviation for "Nippon-style Ride Share" or "Nihon-gata Ride Share," and refers to a service in which ordinary drivers transport users for a fee using their own cars, etc. In this embodiment, for example, a case in which the display device 100 is attached to an automobile 10 with a right-hand drive will be taken as an example.

[0013] The display device 100 is provided, for example, in an upper portion of the interior 12 of the automobile 10. For example, the display device 100 is provided above the passenger seat in the interior 12 of the automobile 10. In this embodiment, the display device 100 is detachably attached, for example, to a sun visor 16 (see FIGS. 6 and 7) provided above the passenger seat. The sun visor 16 (see FIGS. 6 and 7) is a sunshade used to protect the eyes of the driver and other passengers from direct sunlight and ensure visibility.

[0014] The display surface 112 of the display device 100 faces the windshield 14 of the automobile 10. Therefore, the display surface 112 of the display device 100 is visible from outside the automobile 10 through the windshield 14. Therefore, the display device 100 can notify the outside of the information displayed on the display surface 112.

[0015] [2. Display Device Configuration] Next, the display device 100 according to this embodiment will be described in more detail with reference to Figures 2 and 3. Figure 2 is a first perspective view showing the display device 100 according to this embodiment. Figure 3 is a second perspective view showing the display device 100 according to this embodiment.

[0016] As shown in FIGS. 2 and 3, the display device 100 according to this embodiment includes a display main body 110 and an attachment mechanism 210.

[0017] The display main body 110 has a display surface 112. The display surface 112 displays predetermined information. The predetermined information is, for example, information indicating that the automobile 10 is used for ride sharing.

[0018] The mounting mechanism 210 detachably mounts the display main body 110 to the sun visor 16 (see FIGS. 6 and 7) so that the display surface 112 faces the windshield 14 of the automobile 10.

[0019] The attachment mechanism 210 according to this embodiment includes, for example, a support plate 250 and a clip 310.

[0020] The support plate 250 is a plate that protrudes from the display unit main body 110 toward the opposite side (-Y direction) of the display surface 112. The support plate 250 protrudes in the -Y direction (rearward), for example, from the upper end portion 110a of the display unit main body 110 or from the vicinity of the upper end portion 110a. The upper end portion 110a is the end portion on the roof lining 20 (see FIGS. 5 to 7) side when the display device 100 is attached to the sun visor 16 (see FIGS. 6 and 7). The support plate 250 has a flat plate shape that is thick enough to be inserted into the gap between the roof lining 20 (see FIGS. 5 to 7) and the sun visor 16 (see FIGS. 6 and 7) inside the vehicle interior 12, for example.

[0021] In this embodiment, the display main body 110 and the support plate 250 may have a dimensional relationship such that the center of gravity of the display device 100 is located at one or both of the support plate 250 and the clip 310, for example.

[0022] The clip 310 is attached to one side of the support plate 250. The clip 310 is attached to, for example, the lower surface of the support plate 250. The lower surface of the support plate 250 is the surface that is disposed vertically below the support plate 250 when the display device 100 is attached to the sun visor 16 (see FIGS. 6 and 7). The clip 310 is a plate that has a base end 310a attached to the support plate 250 and a tip end 310b that is spaced apart from the support plate 250 in the Z direction. The clip 310 is attached to the support plate 250 so that the tip end 310b is disposed further in the protruding direction of the support plate 250 (-Y direction) than the base end 310a.

[0023] As described above, the display device 100 according to this embodiment includes the display main body 110, the support plate 250, and the clip 310, and is configured to be able to clamp the sun visor (see FIGS. 6 and 7) between the support plate 250 and the clip 310. This allows the display device 100 to stably fix the display main body 110 inside the vehicle interior 12.

[0024] [2.1. Display unit configuration] Next, the display main body 110 will be described with reference to Figures 2 to 4. Figure 4 is an exploded perspective view of the display main body 110 according to this embodiment.

[0025] As shown in FIGS. 2 to 4, the display main body 110 includes, for example, a display panel 120 and a housing 130.

[0026] The display panel 120 is a plate that forms the display surface 112. The shape of the display panel 120 may be a flat plate having a planar shape, or may be a curved plate. From the viewpoint of light weight and strength, the material of the display panel 120 is preferably plastic. However, the material is not limited to this example, and the display panel 120 may be made of other materials such as glass or metal.

[0027] In this embodiment, at least a portion of the display surface 112 transmits light emitted by a light-emitting unit 160, which will be described later.

[0028] The display board 120 includes, for example, a transmissive portion 122 and a light-shielding portion 124. The transmissive portion 122 is a region of the display board 120 that transmits visible light. The visible light transmittance of the transmissive portion 122 is not particularly limited, but may be a predetermined value of, for example, 80% or more and 100% or less. The transmissive portion 122 transmits light emitted by the light-emitting portion 160. In this embodiment, the visible light emitted to the outside from the transmissive portion 122 is one or both of blue light and white light. Note that the visible light emitted to the outside from the transmissive portion 122 is preferably bluish-white light. This further improves the visibility of the display board 120 (display surface 112) when viewed from outside the vehicle at night. Furthermore, during the daytime, the visibility of the display board 120 (display surface 112) when viewed from outside the vehicle can further improve. That is, when the display board 120 (display surface 112) is viewed from outside the vehicle, the visibility of the display board 120 (display surface 112) can be further improved regardless of the time of day. Also, when the display board 120 (display surface 112) is viewed from outside the vehicle in the morning, evening, just before sunrise, or just after sunset, the visibility of the display board 120 (display surface 112) can be further improved. That is, when the display board 120 (display surface 112) is viewed from outside the vehicle, the visibility of the display board 120 (display surface 112) can be further improved regardless of the time of day.

[0029] Regardless of the wavelength of the light emitted by the light-emitting unit 160, the visible light emitted outward from the transmissive unit 122 may be one or both of blue light and white light. In other words, the visible light emitted by the light-emitting unit 160 and transmitted through the transmissive unit 122 may be one or both of blue light and white light. For example, the light-emitting unit 160 may emit one or both of blue light and white light, and the transmissive unit 122 may transmit the light emitted by the light-emitting unit 160 outward as is. Alternatively, the light-emitting unit 160 may emit white light, and the transmissive unit 122 may transmit the blue light of the white light emitted by the light-emitting unit 160. As long as the visible light emitted outward from the transmissive unit 122 is one or both of blue light and white light, the wavelength of the light emitted by the light-emitting unit 160 is not limited. For example, the light-emitting unit 160 may emit ultraviolet light.

[0030] The light-shielding portion 124 is a region of the display panel 120 that blocks visible light. The light-shielding portion 124 blocks light emitted by the light-emitting portion 160. The light-shielding rate of the light-shielding portion 124 is a predetermined value, for example, not less than 80% and not more than 100%.

[0031] Display board 120 displays predetermined information depending on the shape of one or both of transmissive portion 122 and light-shielding portion 124. For example, when characters are displayed by transmissive portion 122 partitioned by light-shielding portion 124, the dimensions of one character are predetermined, for example, 40 mm in height x 27 mm in width or more.

[0032] In this embodiment, a plurality of notches 126 are formed in the display panel 120. The notches 126 are formed at positions corresponding to bosses 146 of the front frame 140, which will be described later. The size of the notches 126 is slightly larger than that of the bosses 146 of the front frame 140.

[0033] The housing 130 has, for example, a hollow shape. A display panel 120 is provided on the front surface of the housing 130.

[0034] The housing 130 has a light-blocking property that blocks visible light from radiating from inside the housing 130 to outside the housing 130. The light-blocking rate of the housing 130 is a predetermined value, for example, not less than 80% and not more than 100%. The material of the housing 130 is preferably plastic from the viewpoint of light weight and strength. However, the material is not limited to this example, and the housing 130 may be made of other materials such as metal or wood. The housing 130 has a side surface 130a that surrounds the outer edge of the display panel 120, and a back surface 130b.

[0035] In this embodiment, the housing 130 includes, for example, a front frame 140 and a housing main body 150 .

[0036] The front frame 140 is box-shaped and has a front surface 142 and side surfaces 144. The front surface of the front surface 142 (the surface located in the +Y direction) is the surface that becomes the front surface of the housing 130 (display main body 110). When the display device 100 is attached to the sun visor 16 (see FIGS. 6 and 7), the front surface of the front surface 142 faces the windshield 14 of the automobile 10.

[0037] An opening 142a is formed in the front surface 142. The size of the opening 142a is smaller than that of the display panel 120.

[0038] The side surface portion 144 stands on the rear side (-Y direction) from the front surface portion 142. The side surface portion 144 forms a surface that becomes the side surface 130a of the housing 130 (display main body 110). The inner periphery of the side surface portion 144 is larger than the outer periphery of the display panel 120.

[0039] In this embodiment, one or more bosses 146 are provided on the rear surface (surface located in the -Y direction) of the front surface portion 142. The bosses 146 protrude in the -Y direction from the rear surface of the front surface portion 142. The bosses 146 are, for example, cylindrical. The bosses 146 are formed at positions corresponding to the notches 126 of the display panel 120 and the boss portions 152 of the housing main body 150.

[0040] The housing main body 150 is box-shaped with an opening 150a. The outer edge of the housing main body 150 on the opening 150a side has a shape that is substantially the same as the outer edge of the side surface portion 144 of the front frame 140. For example, when the front frame 140 is fixed to the housing main body 150, the side surface 130a of the side surface portion 144 of the front frame 140 and the side surface 150b of the housing main body 150 are flush with each other. The back surface of the housing main body 150 becomes the back surface 130b of the housing 130 (display unit main body 110).

[0041] In this embodiment, the inner surface of the housing body 150 is provided with one or more boss portions 152, one or more display panel fixing portions 154, one or more substrate fixing portions 156, and one or more support plate fixing portions 158.

[0042] The boss portion 152 is provided at a position corresponding to the boss 146 of the front frame 140. The boss portion 152 protrudes in the +Y direction from the inner surface of the housing main body 150. A through hole 152a is formed in the boss portion 152. The boss portion 152 has, for example, a cylindrical shape. The inner diameter of the through hole 152a is slightly larger than the shank of a first male screw (not shown) described below and smaller than the head of the first male screw.

[0043] The display board fixing portion 154 is provided to fix the display board 120 inside the housing 130. The display board fixing portion 154 is provided along the outer edge of the opening 150a. The display board fixing portion 154 protrudes outward in the +Y direction beyond the side surface 150b. The tip surface of the display board fixing portion 154 is flat or approximately flat.

[0044] The substrate fixing portion 156 is provided to fix the substrate 162 (described later) within the display unit main body 110. The substrate fixing portion 156 is provided, for example, within an area surrounded by multiple boss portions 152. The substrate fixing portion 156 includes a fixing plate 156a and a screw groove 156b. The fixing plate 156a is a plate member that rises in the +Y direction from the inner surface of the housing main body 150. The tip surface of the fixing plate 156a is flat or approximately flat. The fixing plate 156a has the function of positioning the substrate 162 and the function of supporting the substrate 162. The screw groove 156b is provided in the fixing plate 156a. The screw groove 156b is provided, for example, in approximately the center of the housing main body 150 in the Z direction.

[0045] The support plate fixing portion 158 is provided to fix the support plate 250 to the display unit main body 110. The support plate fixing portion 158 is provided, for example, in an area surrounded by multiple boss portions 152. The support plate fixing portion 158 rises in the +Y direction from the inner surface of the housing main body 150. A screw groove 158a is formed in the support plate fixing portion 158. The screw groove 158a of the support plate fixing portion 158 is provided, for example, on one of a pair of side surfaces 150b of the housing main body 150 arranged in the Z direction.

[0046] The display device 100 according to this embodiment also includes a light-emitting unit 160. The light-emitting unit 160 is provided inside the display main body 110. The light-emitting unit 160 is provided, for example, inside the housing 130. In this embodiment, the light-emitting unit 160 is provided inside the housing main body 150.

[0047] The light-emitting unit 160 includes a substrate 162 and one or more LEDs 164 provided on the substrate 162. The light-emitting unit 160 is, for example, a surface-mounted LED. However, the light-emitting unit 160 is not limited to this example, and may also be a tape LED.

[0048] One or more through holes 162a are provided in the substrate 162. The through holes 162a are provided at positions corresponding to the screw grooves 156b of the substrate fixing portion 156. The through holes 162a are slightly larger than the shaft portion of a second male screw (not shown) described below, but smaller than the head portion of the second male screw.

[0049] Furthermore, the display unit main body 110 according to this embodiment has a power connection unit 170 that connects the light emitting unit 160 to a power cable (not shown). The power connection unit 170 is provided on the end side of the display unit main body 110. The power cable connects a power source spot in the vehicle interior 12 to the power connection unit 170.

[0050] In this embodiment, the power connection unit 170 is provided on one end side of the rear surface 130b of the housing main body 150. For example, when the display device 100 is attached to the sun visor 16 (see FIGS. 6 and 7), this end is the end on the side of the side window 18 (see FIG. 7) of the automobile 10. For example, when the display device 100 is attached to the sun visor 16 (see FIGS. 6 and 7) provided on the passenger seat, this end is the end on the side of the side window 18 (see FIG. 7) on the passenger seat side of the automobile 10.

[0051] [2.2. How to assemble the display unit] Next, a method for assembling the display main body 110 will be described with reference to FIG. 4. First, the light-emitting unit 160 is fixed to the housing main body 150. Specifically, the light-emitting unit 160 is placed on the tip surface of the substrate fixing portion 156 so that the screw groove 156b of the substrate fixing portion 156 corresponds to the through-hole 162a of the substrate 162 of the light-emitting unit 160. Then, a second male screw (not shown) is inserted into the through-hole 162a of the substrate 162 of the light-emitting unit 160. The shaft of the second male screw is not threadedly engaged with the through-hole 162a, and the outer diameter of the shaft of the second male screw is smaller than the inner diameter of the through-hole 162a. Therefore, the second male screw is rotatable within the through-hole 162a. Meanwhile, the tip side of the shaft of the second male screw is threadedly engaged with the screw groove 156b of the substrate fixing portion 156. Therefore, the deeper the second male screw is screwed into the screw groove 156b, the more the head of the second male screw can be moved in the -Y direction. Then, the second male screw is screwed into the screw groove 156b until the board 162 of the light-emitting unit 160 is locked by the head of the second male screw. In this way, the light-emitting unit 160 is fixed to the housing main body 150 by the second male screw.

[0052] Then, display board 120 is placed on the tip surface of display board fixing portion 154 from above light-emitting portion 160. Specifically, display board 120 is placed on the tip surface of display board fixing portion 154 so that notch 126 of display board 120 corresponds to boss portion 152 of housing main body 150.

[0053] Next, the front frame 140 is placed on the housing body 150 from above the display panel 120. Specifically, the front frame 140 is placed on the housing body 150 so that the boss portion 152 of the housing body 150 and the boss 146 of the front frame 140 abut against each other.

[0054] Then, the front frame 140 is fixed to the housing main body 150. Specifically, a first male screw (not shown) is inserted into a through-hole 152a formed in the boss portion 152 of the housing main body 150 from the rear surface 130b side of the housing main body 150. The shank of the first male screw is not threaded into the through-hole 152a, and the outer diameter of the shank of the first male screw is smaller than the inner diameter of the through-hole 152a. Therefore, the first male screw is rotatable within the through-hole 152a. Meanwhile, the tip side of the shank of the first male screw can thread the boss 146 of the front frame 140. Therefore, the deeper the shank of the first male screw threads the boss 146 of the front frame 140, the more the head of the first male screw can move in the +Y direction. Then, the shank of the first male screw threads the boss 146 of the front frame 140 until the head of the first male screw engages the rear surface 130b of the housing main body 150. As a result, the front frame 140 can be fixed to the housing body 150 with the first male screw, with the display board 120 sandwiched between the rear surface of the front surface portion 142 of the front frame 140 and the tip surface of the display board fixing portion 154 of the housing body 150. This makes it possible to restrict movement of the display board 120 in the Y direction. Furthermore, the outer edge of the display board 120 is surrounded by the side surface portion 144 of the front frame 140 of the housing 130. Note that the boss 146 of the front frame 140 fits into the notch 126 of the display board 120, and therefore the boss 146 of the front frame 140 can restrict movement of the display board 120 in the XZ directions.

[0055] As described above, according to the method for assembling the display unit main body 110 of this embodiment, by simply threading the boss 146 of the front frame 140 with the first male screw, the front frame 140 can be fixed to the housing main body 150 with the display board 120 sandwiched between the front frame 140 and the housing main body 150. Furthermore, by simply removing the first male screw from the boss 146 of the front frame 140, the restriction on movement of the display board 120 in the Y direction can be released, and the display board 120 can be easily removed from the housing 130. Therefore, according to the method for assembling the display unit main body 110 of this embodiment, the display board 120 can be easily replaced.

[0056] Furthermore, the front frame 140 and the housing body 150 are designed so that there is no gap between the front frame 140 and the housing body 150 when the front frame 140 is fixed to the housing body 150. The head of the first male screw is designed so that the through-hole 152a formed in the boss portion 152 of the housing body 150 is closed by the head when the rear surface 130b of the housing body 150 is locked by the head. Furthermore, as described above, the front frame 140 and the housing body 150 have light-blocking properties. This allows light emitted from the light-emitting portion 160 to pass only through the display panel 120, for example, only through the transmissive portion 122 of the display panel 120, and then be emitted to the outside.

[0057] This makes it possible to prevent the light emitted from the light emitting unit 160 from being emitted into the vehicle interior 12 through the housing 130. Therefore, the display device 100 can emit light appropriately.

[0058] Furthermore, in the display unit main body 110, the outer edge of the display board 120 is surrounded by the side surface portion 144 of the front frame 140. This makes it possible to suppress diffusion of visible light transmitted through the display board 120 in the ±X directions. This makes it possible to prevent the light emitted from the light-emitting unit 160 from directly hitting the driver of the automobile 10. This makes it possible to suppress a decrease in visibility for the driver of the automobile 10. Similarly, it makes it possible to prevent the light emitted from the light-emitting unit 160 from directly hitting other passengers of the automobile 10 other than the driver of the automobile 10. This makes it possible to suppress a decrease in visibility for other passengers of the automobile 10 other than the driver of the automobile 10.

[0059] Furthermore, the visible light transmitted through the transmissive portion 122 of the display panel 120 has high directivity, and most of it travels straight in the +Y direction. Therefore, even if the visible light emitted from the display main body 110 is reflected by the windshield 14, it is possible to prevent the reflected light from directly hitting the driver of the automobile 10. Similarly, it is possible to prevent the reflected light from directly hitting other passengers of the automobile 10 other than the driver.

[0060] [2.3. Light-emitting unit configuration] Next, the configuration of the light-emitting unit 160 will be described. The LED 164 of the light-emitting unit 160 emits, for example, visible light. The LED 164 of the light-emitting unit 160 emits, for example, one or both of blue light and white light. It is preferable that the LED 164 of the light-emitting unit 160 emits bluish-white light.

[0061] Furthermore, it is preferable that the LEDs 164 of the light-emitting unit 160 are top-view. A top-view LED is an LED that emits light from the front. This allows visible light to be efficiently emitted to the outside through the transmissive portion 122 of the display panel 120. However, the present invention is not limited to this example, and the LEDs 164 of the light-emitting unit 160 may be side-view. A side-view LED is an LED that emits light from the side.

[0062] Furthermore, it is preferable that the plurality of LEDs 164 constituting the light-emitting unit 160 are arranged so that visible light is emitted substantially uniformly from the entire surface of the transmissive portion 122 of the display board 120. This can improve the visibility of the display surface 112. Note that it is not necessary to install the LEDs 164 at positions on the display board 120 that correspond to the light-shielding portions 124. This can reduce the cost of the light-emitting unit 160.

[0063] The lighting control of the LED 164 may be dynamic control or static control. Dynamic control, also known as pulse lighting control or duty lighting control, is a control that lights up the LED at a constant frequency. Static control, also known as DC lighting control, is a control that constantly applies current to the LED.

[0064] Furthermore, the luminous intensity of the light-emitting unit 160 is not particularly limited as long as it is a predetermined value of 300 cd or less, provides high visibility from outside the vehicle, and minimizes the impairment of driver visibility. The luminous intensity of the light-emitting unit 160 may be, for example, a predetermined value of 10 cd or more and 100 cd or less. The luminous intensity of the light-emitting unit 160 may also be a predetermined value of 10 cd or more and 50 cd or less, or may be around 30 cd.

[0065] [2.4. Support Plate Configuration] Next, the support plate 250 will be described with reference to Figures 2, 3, 5, and 6. Figure 5 is a first side view of the display device 100 according to this embodiment. Figure 6 is a second side view of the display device 100 according to this embodiment.

[0066] 2, 3, 5, and 6, in this embodiment, the support plate 250 is bent. The support plate 250 includes, for example, a connecting portion 252 and an extending portion 254. From the viewpoints of lightness and strength, the material of the support plate 250 is preferably plastic. However, the material of the support plate 250 is not limited to this example, and the material of the support plate 250 may be other materials such as metal or wood.

[0067] The connection portion 252 is a portion that is connected to the housing 130. In this embodiment, the connection portion 252 is connected to the housing 130 by threading the shaft portion of a third male screw (not shown) into the screw groove 158a of the support plate fixing portion 158 of the housing main body 150. The connection portion 252 protrudes in the -Y direction, for example. The angle formed between the protruding direction of the connection portion 252 and the display surface 112 is, for example, 90 degrees.

[0068] The extending portion 254 is a portion that continues from the connecting portion 252 and is inclined in the −Z direction relative to the connecting portion 252.

[0069] Thus, the support plate 250 includes the connecting portion 252 and the extending portion 254. This allows both the connecting portion 252 and the extending portion 254 to come into contact with the roof lining 20 of the automobile 10 (see FIGS. 5 to 7).

[0070] The bending angle α on the upper surface of the support plate 250 is an obtuse angle. In other words, the angle α formed between the connecting portion 252 and the extending portion 254 on the upper surface of the support plate 250 is an obtuse angle. The bending angle α is, for example, 120 degrees or more and 180 degrees or less, preferably 130 degrees or more and 170 degrees or less, and more preferably 160 degrees. This allows the connecting portion 252 and the extending portion 254 to be brought into suitable contact with the roof lining 20 (see FIGS. 5 to 7) regardless of the type of automobile 10.

[0071] [2.5. Clip Structure] Next, clip 310 will be described with reference to Figures 2, 3, 5, and 6. As shown in Figures 2, 3, 5, and 6, clip 310 is attached to the lower surface of support plate 250 in a cantilevered manner.

[0072] 5 and 6, when the sun visor 16 is sandwiched between the support plate 250 and the clip 310, the clip 310 preferably elastically deforms in a direction away from the sun visor 16, thereby generating a biasing force in a direction pressing the sun visor 16 against the support plate 250. From the viewpoints of weight reduction, strength, and generation of biasing force, the clip 310 is preferably made of plastic. However, the clip 310 is not limited to this example, and may be made of other materials such as metal or wood.

[0073] In this embodiment, the clip 310 has an erect portion 312, a bent portion 314, and a curved portion 316. The erect portion 312 is a portion that rises from the base end portion 310a in a direction away from the support plate 250. As shown in FIG. 6, the erect portion 312 preferably comes into contact with the tip of the sun visor 16 that is located on the windshield 14 side. The bent portion 314 is a portion that is bent from the erect portion 312 into a substantially circular shape.

[0074] Curved portion 316 is a portion that continues from bent portion 314 and extends in the protruding direction of support plate 250. Tip portion 310b is formed in curved portion 316. Curved portion 316 has a curved shape that moves from bent portion 314 side toward tip portion 310b side, first approaching support plate 250, and then moving away from support plate 250 toward tip portion 310b side. Because curved portion 316 has a curved shape, when attaching display device 100 to sun visor 16, sun visor 16 can be easily inserted between support plate 250 and clip 310.

[0075] The narrowest distance between the curved portion 316 and the support plate 250 is a predetermined distance that is equal to or greater than 0 mm and less than the thickness of the sun visor 16. This allows the clip 310 to generate a biasing force in a direction that presses the sun visor 16 against the support plate 250 when the sun visor 16 is sandwiched between the support plate 250 and the clip 310.

[0076] Furthermore, it is preferable that the distance between the tip 310b of the curved portion 316 and the support plate 250 is a predetermined distance that is equal to or greater than the thickness of the sun visor 16. This allows the sun visor 16 to be easily inserted between the support plate 250 and the clip 310 when attaching the display device 100 to the sun visor 16.

[0077] [2.6. Configuration of adjustment mechanism] The display device 100 according to this embodiment may also include an adjustment mechanism 350. As shown in Figures 2, 3, 5, and 6, in this embodiment, the clip 310 is attached to the support plate 250 so as to be slidable in the protruding direction (-Y direction) of the support plate 250. For example, the clip 310 is attached to the support plate 250 so as to be slidable also in the +Y direction.

[0078] The adjustment mechanism 350 is configured to be able to adjust the position in the protruding direction (-Y direction) of the clip 310. For example, the adjustment mechanism 350 is configured to be able to adjust the position in the +Y direction of the clip 310. The adjustment mechanism 350 includes, for example, a through groove 352 and an adjustment screw 354.

[0079] The through grooves 352 are formed in the support plate 250. The through grooves 352 extend in the ±Y directions. In this embodiment, two through grooves 352 are formed in the support plate 250. The adjustment screws 354 attach the clips 310 to the through grooves 352. In this embodiment, the number of adjustment screws 354 provided corresponds to the number of through grooves 352. For example, if two through grooves 352 are formed, two adjustment screws 354 are provided. By loosening the adjustment screws 354, the clips 310 can slide in the front-to-rear directions (±Y directions) relative to the support plate 250.

[0080] The clip 310 is slidable by an adjustment mechanism 350 between a forward-most position shown by a solid line in FIG. 5 and a rearward-most position shown by a dashed line in FIG.

[0081] Then, when the clip 310 is in the desired position, the adjustment screw 354 can be tightened to lock the clip 310 in place.

[0082] 5 and 6, in this embodiment, the range of position adjustment by adjustment mechanism 350 preferably includes an adjustment position where both connection portion 252 and extension portion 254 of support plate 250 contact the roof lining 20. Also, in this embodiment, the range of position adjustment by adjustment mechanism 350 preferably includes an adjustment position where upright portion 312 of clip 310 contacts the tip of sun visor 16 located on the windshield 14 side.

[0083] [2.7. How to install the display device] Next, a method for attaching the display device 100 will be described with reference to Figures 6 and 7. Figure 7 is a diagram showing the display device 100 in use.

[0084] 6 and 7, first, with the sun visor 16 folded, the extension portion 254 of the support plate 250 is inserted from the windshield 14 side into the gap between the roof lining 20 and the sun visor 16. Then, the sun visor 16 is inserted between the support plate 250 and the clip 310.

[0085] Then, the adjustment screw 354 of the adjustment mechanism 350 is loosened, and the position of the clip 310 is adjusted so that both the connecting portion 252 and the extending portion 254 of the support plate 250 come into contact with the roof lining 20. Once the connecting portion 252 and the extending portion 254 of the support plate 250 come into contact with the roof lining 20, the adjustment screw 354 of the adjustment mechanism 350 is tightened. At this time, it is preferable that the erected portion 312 of the clip 310 come into contact with the tip of the sun visor 16 that is located on the windshield 14 side.

[0086] Before attaching the display device 100 to the sun visor 16, the adjustment screw 354 of the adjustment mechanism 350 may be loosened in advance, and the extension portion 254 of the support plate 250 may be inserted into the gap between the roof lining 20 and the sun visor 16. After inserting the sun visor 16 between the support plate 250 and the clip 310, the position of the support plate 250 may be adjusted so that both the connection portion 252 and the extension portion 254 of the support plate 250 are in contact with the roof lining 20, and then the adjustment screw 354 may be tightened.

[0087] 2.8. Display Dimensions [2.8.1. Dimensions of the display unit] Next, an example of the dimensions of the display main body 110 will be described. The length of the display panel 120 in the X direction is longer than the length in the Z direction. The length of the display panel 120 in the X direction is, for example, a predetermined length that is 2.5 to 3.5 times the length in the Z direction, and is preferably 3 times the length. The length of the display panel 120 in the X direction is, for example, 223 mm. The length of the display panel 120 in the Z direction is, for example, 77 mm.

[0088] The length of the housing 130 in the X direction is longer than the length in the Z direction. The length of the housing 130 in the X direction is, for example, a predetermined length that is 2.5 times or more and 3.5 times or less than the length in the Z direction, and is preferably 3 times the length. The length of the housing 130 in the X direction is, for example, 237.75 mm. The length of the housing 130 in the Z direction is, for example, 81.75 mm. Furthermore, the thickness of the housing 130 (length in the Y direction) is shorter than the length in the Z direction. The thickness of the housing 130 is, for example, 1 / 3 times the length in the Z direction. The thickness of the housing 130 is, for example, 26.9 mm.

[0089] The length in the X direction of opening 142a of front frame 140 of housing 130 is longer than the length in the Z direction. The length in the X direction of opening 142a of front frame 140 is, for example, a predetermined length that is 3.0 times or more and 4.0 times or less, and preferably 3.5 times, the length in the Z direction. The length in the X direction of opening 142a of front frame 140 is, for example, 220 mm. The length in the Z direction of opening 142a of front frame 140 is, for example, 64 mm.

[0090] Furthermore, in the display unit main body 110, it is preferable that the distance between the LEDs 164 and the display board 120 is short from the viewpoint of weight reduction. On the other hand, in the display unit main body 110, it is preferable that the distance between the LEDs 164 and the display board 120 is relatively long from the viewpoint of visibility of the display surface 112. Therefore, the shortest distance between the LEDs 164 and the display board 120 is, for example, a predetermined distance of 10 mm or more and 30 mm or less. The shortest distance between the LEDs 164 and the display board 120 is preferably a predetermined distance of 10 mm or more and 20 mm or less, more preferably a predetermined distance of 13 mm or more and 17 mm or less, and even more preferably 14.7 mm. This makes it possible to suppress variations in the luminous intensity (point light) of the visible light emitted from the transmissive portion 122 of the display board 120. This allows visible light to be emitted from the entire surface of the transmissive portion 122 of the display panel 120 with approximately uniform luminous intensity, making it possible to improve the visibility of the display surface 112 while reducing the weight of the display unit main body 110.

[0091] 2.8.2. Dimensions of support plate and clip Next, an example of the dimensions of the support plate 250 and the clip 310 will be described.

[0092] The connection portion 252 of the support plate 250 protrudes, for example, 13 mm in the -Y direction from the housing 130. The thickness (length in the Z direction) of the extension portion 254 of the support plate 250 is smaller than the gap between the roof lining 20 and the sun visor 16, for example.

[0093] The sum of the X-direction length and Z-direction length of the display main body 110 is preferably a predetermined length that is, for example, 2.5 times or less the length of the extending portion 254 of the support plate 250 in the protruding direction. Due to this dimensional relationship between the display main body 110 and the support plate 250, the center of gravity of the display device 100 can be located at one or both of the support plate 250 and the clip 310. The X-direction length of the display main body 110 is the same as the X-direction length of the housing 130, or is approximately ±1 mm from the X-direction length of the housing 130. The Z-direction length of the display main body 110 is the same as the Z-direction length of the housing 130, or is approximately ±1 mm from the Z-direction length of the housing 130. The protruding direction length of the extending portion 254 of the support plate 250 is, for example, 140.5 mm.

[0094] The through groove 352 of the adjustment mechanism 350 is provided, for example, with its starting point at a position 72.8 mm from the tip of the extension portion 254 of the support plate 250. The length of the through groove 352 of the adjustment mechanism 350 in the protruding direction is, for example, 51.3 mm.

[0095] Furthermore, it is preferable that the weight of the display main body 110 be 2.5 times or less the weight of the attachment mechanism 210. This allows the center of gravity of the display device 100 to be located at one or both of the support plate 250 and the clip 310. The weight of the display main body 110 is, for example, 140 g. The weight of the attachment mechanism 210 is, for example, 65 g.

[0096] [3. Summary] When a private vehicle is used for ride-sharing, a display device may be installed to visually notify people outside the vehicle that the vehicle is being used for ride-sharing. Furthermore, when a private vehicle is used for personal use, the display device can become a nuisance, which is a problem. For this reason, a display device that can be easily attached to and detached from the vehicle 10 is preferable. Furthermore, a display device that does not easily fall off due to vibrations while driving is preferable. Furthermore, a display device that is highly durable is preferable in terms of frequent attachment and detachment, exposure to sunlight, and exposure to high-temperature environments. Furthermore, a display device that does not obstruct the driver's field of view as much as possible is preferable. Furthermore, a display device that does not obstruct the driver's visibility as much as possible when the driver is driving is preferable. Furthermore, a display device that does not obstruct the field of view of passengers other than the driver as much as possible is preferable. Furthermore, a display device that does not obstruct the visibility of passengers other than the driver as much as possible is preferable. Furthermore, a display device that does not obstruct the visibility of passengers other than the driver to the outside of the vehicle as much as possible is preferable. Furthermore, a display device that is as lightweight as possible is preferable in terms of ease of handling, drop resistance (impact resistance), and injury prevention. Furthermore, a display device that is highly visible to people outside the vehicle is preferable. Furthermore, a display device that is highly visible to people outside the vehicle regardless of the time of day is even more preferable.

[0097] Therefore, the display device 100 according to this embodiment is a display device 100 that is detachably attached to, for example, a sun visor 16 provided in the passenger compartment 12 of an automobile 10, and includes a display unit main body 110 having a display surface 112, a support plate 250 that protrudes from the display unit main body 110 toward the opposite side of the display surface 112, and a clip 310 that has a base end 310a attached to one side of the support plate 250 and a tip end 310b that is disposed in the protruding direction of the support plate 250 relative to the base end 310a, and is configured to be able to clamp the sun visor between the support plate 250 and the clip 310. This allows the display device 100 according to this embodiment to be appropriately attached to the automobile 10. Furthermore, compared to when the display device 100 is provided on the dashboard of the automobile 10, the display device 100 according to this embodiment can significantly reduce the area that obstructs the driver's field of view, thereby ensuring the driver's field of view. Similarly, the display device 100 according to this embodiment can significantly reduce the area in which the view of passengers other than the driver is obstructed, compared to when the display device 100 is provided on the dashboard of the automobile 10. Furthermore, the display device 100 according to this embodiment can be prevented from falling off even when vibrations occur as the automobile 10 travels, compared to when the display device 100 is provided on the dashboard of the automobile 10.

[0098] The clip 310 may be attached to the support plate 250 so as to be slidable in the protruding direction, and may include an adjustment mechanism 350 configured to adjust the position of the clip 310 in the protruding direction. This makes it possible for the display device 100 according to this embodiment to adjust the front-to-rear position of the clip 310 to match the size, shape, installation position, etc. of the sun visor 16.

[0099] Furthermore, the support plate 250 may be bent, and the bending angle on the other side of the support plate 250 may be an obtuse angle. This allows the display device 100 according to this embodiment to have a large contact area between the support plate 250 and the roof lining 20, and makes it possible to suppress rattling of the display device 100 even if vibrations occur due to the automobile 10 traveling.

[0100] The support plate 250 may also be in the form of a flat plate having a thickness that allows it to be inserted into the gap between the roof lining 20 in the vehicle interior 12 and the sun visor 16. This allows the display device 100 according to this embodiment to suitably attach the display unit main body 110 to the sun visor 16.

[0101] Furthermore, the support plate 250 includes a connection portion 252 connected to the display unit main body 110 and an extension portion 254 that is continuous from the connection portion 252 and is inclined relative to the connection portion 252, the angle formed between the connection portion 252 and the extension portion 254 on the other side surface of the support plate 250 is an obtuse angle, the support plate 250 is configured to be insertable into the gap between the roof lining 20 and the sun visor 16 in the vehicle interior 12, and the range of position adjustment by the adjustment mechanism 350 may include an adjustment position where both the connection portion 252 and the extension portion 254 of the support plate 250 contact the roof lining 20. As a result, the display device 100 according to this embodiment can reliably bring both the connection portion 252 and the extension portion 254 of the support plate 250 into contact with the roof lining 20. Therefore, the display device 100 of this embodiment can increase the contact area between the support plate 250 and the roof lining 20, and even if vibrations occur due to the automobile 10 moving, rattling of the display device 100 can be suppressed.

[0102] Furthermore, the clip 310 may generate a biasing force in a direction pressing the sun visor 16 against the support plate 250 when the sun visor 16 is sandwiched between the support plate 250 and the clip 310. As a result, the clip 310 according to this embodiment can stably fix the display unit main body 110 inside the vehicle interior 12 without including a member such as a spring. Furthermore, the clip 310 according to this embodiment generates a biasing force only through elastic deformation, so it can be easily detached from the sun visor 16. Therefore, the display device 100 according to this embodiment can be easily attached to and detached from the sun visor 16. Furthermore, because the clip 310 according to this embodiment does not include a member such as a spring, the number of parts and assembly steps can be reduced, and the manufacturing cost of the display device 100 can be reduced. Furthermore, as described above, the display device 100 of this embodiment can stably fix the display unit main body 110 within the vehicle interior 12 without the need for components such as springs, by using one or a combination of the following: an adjustment mechanism 350 that can reduce weight, increase the length of the support plate 250, and increase the contact area between the roof lining 20 and the support plate 250 (connection portion 252 and extension portion 254), and a clip 310 that can generate a biasing force.

[0103] Furthermore, the display unit main body 110 and the support plate 250 may have a dimensional relationship such that the center of gravity of the display device 100 is located at one or both of the support plate 250 and the clip 310. This makes it possible for the display device 100 according to this embodiment to avoid a situation in which the display device 100 becomes displaced or comes off due to vibrations caused by the automobile 10 traveling.

[0104] Furthermore, the support plate 250 may extend from the upper end of the display main body 110. As a result, the display device 100 according to this embodiment can cause the display main body 110 to hang down by the support plate 250, and can stably fix the display main body 110 to the sun visor 16.

[0105] Furthermore, a light-emitting unit 160 may be provided inside the display main body 110, and at least a portion of the display surface 112 of the display main body 110 may transmit light emitted by the light-emitting unit 160. As a result, the display device 100 according to this embodiment can further improve the visibility of the display surface 112 when the display surface 112 is viewed from outside the vehicle at night. Furthermore, the display device 100 according to this embodiment can further improve the visibility of the display surface 112 when the display surface 112 is viewed from outside the vehicle during the day. In other words, the display device 100 according to this embodiment can further improve the visibility of the display surface 112 when the display surface 112 is viewed from outside the vehicle, regardless of whether it is day or night. Furthermore, the display device 100 according to this embodiment can further improve the visibility of the display surface 112 when the display surface 112 is viewed from outside the vehicle in the morning, in the evening, just before sunrise, or just after sunset. That is, the display device 100 according to this embodiment can further improve the visibility of the display surface 112 when the display surface 112 is viewed from outside the vehicle, regardless of the time of day.

[0106] Furthermore, the display unit main body 110 may have a power connector 170 that connects the light-emitting unit 160 and a power cable, and the power connector 170 may be provided on the end side of the display unit main body 110. In this embodiment, by providing the power connector 170 on the end side of the display unit main body 110, the power cable can be installed inside the A-pillar on the side of the side window 18 or at the boundary between the windshield 14 and the A-pillar. This makes it possible for the display device 100 according to this embodiment to suppress the vibration of the power cable caused by vibrations associated with the running of the automobile 10. Therefore, the display device 100 according to this embodiment can prevent the power cable from unintentionally falling off the power connector 170 or a power spot.

[0107] If the power connector 170 is provided below the display main body 110, the weight of the components constituting the power connector 170 and the weight of the power cable connected to the power connector 170 will further lower the center of gravity of the display main body 110. However, in the display device 100 according to this embodiment, the power connector 170 is provided on the side edge side (e.g., the left edge side) of the display main body 110, thereby preventing the center of gravity of the display main body 110 from being lowered. Furthermore, if the power connector 170 is provided on the lower or upper side of the display main body 110, it is difficult to ensure a routing path for the power cable to the power spot that does not obstruct the field of view of the driver or passenger in the front passenger seat. In contrast, in the display device 100 according to this embodiment, the power connector 170 is provided on the side edge side of the display main body 110, thereby making it easy to ensure a routing path for the power cable to the power spot that does not obstruct the field of view of the driver or passenger in the front passenger seat.
