Description

[Technical field]

[0001] The present invention relates to a display device. [Background technology]

[0002] There are rearview confirmation devices for assisting drivers in checking behind two-wheeled and three-wheeled vehicles. Patent Document 1 discloses a rearview confirmation device for motorcycles that can effectively display information about the rear of the vehicle in an easy-to-see size even on a small display screen. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 4948115 specification Summary of the Invention [Problem to be solved by the invention]

[0004] In the rearview confirmation device described in Patent Document 1, when a driver is driving and wants to check the display screen of the rearview confirmation device, the driver must lower his / her line of sight from the line of sight while driving. Since this involves the driver moving his / her line of sight, there is a possibility that the driver may neglect to check the road ahead during this time. In addition, for example, when the display screen is provided at the location where the instrument display such as the speedometer is shown, the size of the display screen is restricted by the size of the location where the instrument display is shown, and the size becomes small, making it difficult to maintain visibility.

[0005] Therefore, an object of the present invention is to provide a display device that requires less eye movement when checking the rear of the vehicle and makes it easier to check information behind the vehicle. [Means for solving the problem]

[0006] A display device according to one embodiment of the present invention is mounted on a two- or three-wheeled vehicle with a driver's seat located in the center in the left-right direction, and includes a camera that photographs the rear side of the vehicle, a display unit that displays an image photographed by the camera, and a holder that holds the display unit at a position higher than a speedometer installed on the vehicle.

[0007] According to this aspect, the display unit is held at a higher position than the speedometer installed in the vehicle, so that the driver's line of sight movement when checking the display unit can be reduced. Also, since the display unit is provided separately from the speedometer, the size of the display unit can be made larger without being restricted by the location where the speedometer is installed. This makes it easier for the driver to check the image behind the vehicle.

[0008] In the above aspect, the holder may hold the display unit at a position that is central in the left-right direction.

[0009] This allows the driver to check the display unit without moving his / her line of sight to the left or right of the traveling direction, thereby further reducing line of sight movement.

[0010] In the above aspect, the holder may be located above the speedometer and may hold the display unit in a holding area having a predetermined width centered on the speedometer in the front-rear direction of the vehicle. Also, in the above aspect, the holder may hold the display unit in a position forward of the speedometer in the front-rear direction of the vehicle.

[0011] This ensures good visibility of the speedometer while reducing the amount of eye movement required when checking the display.

[0012] In the above aspect, the holder may be provided with a movable mechanism that allows the orientation of the display unit to be changed. The movable mechanism may be capable of changing the angle between the normal direction of the display unit and the horizontal plane within a range of 10 degrees or more.

[0013] By allowing the driver to change the orientation of the display, the display can be adjusted to an orientation that is more easily visible to the driver depending on the driver's physique and the structure of the vehicle, making it easier for the driver to check information about the area behind the vehicle. Effect of the Invention

[0014] According to the present invention, it is possible to provide a display device that requires less eye movement when checking the rear of the vehicle and makes it easier to check information behind the vehicle. [Brief description of the drawings]

[0015] [Figure 1] 1 is a schematic diagram of a vehicle and a display device according to an embodiment of the present invention. [Diagram 2] FIG. 2 is a diagram illustrating an arrangement position of a display device according to the present embodiment. [Diagram 3] 3A and 3B are diagrams illustrating the orientation of the display device according to the embodiment. [Figure 4] 1 is a schematic diagram of a vehicle and another display device according to an embodiment of the present invention; DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] The present embodiment will be described. Fig. 1 shows a schematic diagram of a motorcycle V equipped with a display device 10 according to the present embodiment. The motorcycle V has a driver's seat S provided at a position that is central in the left-right direction (x direction) of the vehicle body. Also, an instrument section M that displays instruments such as a speedometer is provided at the front of the vehicle. Note that, although the present embodiment will be described taking a motorcycle as an example, the vehicle on which the display device is provided may be a two-wheeled or three-wheeled vehicle.

[0017] The display device 10 includes a camera 101 , a display unit 102 , a holder 103 , and a control unit 104 .

[0018] The camera 101 is provided behind the motorcycle V and is a device that captures images of the rear side of the motorcycle V. The images captured by the camera 101 include still images and videos. The images captured by the camera 101 are transmitted to a control unit 104, which will be described later.

[0019] The display unit 102 is a display on which the image captured by the camera 101 is displayed. The size of the display can be appropriately selected depending on the size of the motorcycle V, and is, for example, 10 inches or less. The size of the display is not restricted by the size of the instrument unit M, so it can be larger than, for example, a general display size of 5 to 6 inches. This improves the visibility of the rider.

[0020] The holding unit 103 is attached to the motorcycle V and holds the display unit 102 at a position higher than a speedometer included in an instrument unit M provided on the motorcycle V. Specifically, the holding unit 103 holds the display unit 102 in an area R having a predetermined width W centered on the speedometer included in the instrument unit M in the front-to-rear direction (y direction) of the motorcycle V. The holding area R is also located above the speedometer included in the instrument unit M. More specifically, the holding unit 103 holds the display unit 102 at a position close to directly above the speedometer included in the instrument unit M. The length of the holding unit in the height direction (z direction) can be adjusted by making the holding unit 103 an expandable member.

[0021] Control unit 104 processes information from camera 101, generates an image that can be displayed on display unit 102, and displays it on display unit 102. Note that the image processing and image generation functions of control unit 104 may be realized as functions built into camera 101.

[0022] The rider of the motorcycle V can direct his / her gaze in the traveling direction (y direction) indicated by the arrow D toward the display unit 102 with less gaze movement than toward the instrument unit M including the speedometer. This reduces the amount of gaze movement required when the rider checks the display unit 102.

[0023] The position of the display unit 102 as viewed from the driver's viewpoint will be described with reference to Fig. 2. Fig. 2 shows a schematic diagram of the display unit 102 and instrument unit M that the driver seated in the driver's seat S faces.

[0024] 2, the holding unit 103 is in the region R and holds the display unit 102 at a position that is the center in the left-right direction (x direction) as indicated by the line L1. This reduces the amount of movement of the driver's line of sight. The holding unit 103 may be attached to the front cover F of the motorcycle V as a retrofit member by a mounting member (not shown) using, for example, bolts and nuts, or may be molded integrally with the front cover F and provided in advance at the time of manufacturing the motorcycle V. For example, by molding the holding unit 103 integrally, it is possible to prevent the position of the display unit 102 from shifting due to loosening of the fastening of the bolts and nuts caused by vibrations while the motorcycle V is traveling.

[0025] As shown in FIG. 2, when viewed from the driver, the display unit 102 is held at a position higher than a speedometer 201 included in the instrument unit M.

[0026] Adjustment of the orientation of the display unit 102 will be described with reference to FIG. 3. As shown in FIG. 3, the display unit 102 is attached to the holding unit 103 via a movable mechanism 301. The movable mechanism 301 is, for example, a member using a hinge, and enables the orientation of the display unit 102 to be changed. The movable mechanism 301 enables the angle between the normal direction of the display unit 102 indicated by the line L2 and the horizontal plane H (xy plane) to be changed within a range of 10 degrees or more. The driver can change the orientation of the display unit 102 by adjusting the angle of the display unit 102 with respect to the holding unit 103. This allows the display unit 102 to be adjusted to an orientation that is easier for the driver to view.

[0027] The display device 10A will be described with reference to Fig. 4. The display device 10A is a device in which the display unit 102 is disposed farther from the driver's seat S than the display device 10. Fig. 4 shows a schematic diagram of a motorcycle V on which the display device 10A according to this embodiment is mounted. In the display device 10A, the holder 103A holds the display unit 102 in a position forward of a speedometer included in the instrument unit M.

[0028] By using the display device 10 that holds the display unit 102 in a position close to directly above the speedometer included in the instrument unit M, or the display device 10A that holds the display unit 102 in a position opposite the driver's seat S across the speedometer included in the instrument unit M, it is possible to reduce the driver's line of sight movement when checking the display unit, compared to a retrofit display device that is attached to the handlebar or the front side of the speedometer, for example. Also, if a retrofit display device is attached to the handlebars located above the instrument unit M in order to reduce line of sight movement, it is considered that the visibility of the speedometer will decrease. On the other hand, the display devices 10 and 10A do not reduce the visibility of the speedometer and can reduce the driver's line of sight movement when checking the display unit.

[0029] The above-described embodiment is intended to facilitate understanding of the present invention, and is not intended to limit the present invention. The elements of the embodiment, as well as their arrangement, shape, size, and the like, are not limited to those exemplified, and may be modified as appropriate. [Explanation of symbols]
