Description

Digital side rear-view mirror structure Technical Field The present application relates to a digital side mirror configuration using an electronic image pickup apparatus equipped to a vehicle. Background With the progress of automobile technology, a technology has been spread in which objects inside and outside a vehicle are recognized by a camera, radar, or the like in a vehicle such as a Van (Van), a truck (truck), or a bus, and a device mounted on the vehicle is made to function based on the information. For example, patent document 1 describes an electronic side mirror device (digital side mirror) as a side mirror using a digital camera. The electronic side mirror device includes a door camera for capturing an image of a side of a vehicle on an outer side of a front end of a door of the vehicle. In this electronic side mirror device, an image captured by a door camera is projected by a projector device onto hologram optical elements disposed on a front window and a side window. Prior art literature Patent literature Patent document 1 Japanese patent laid-open publication No. 2011-213186 Disclosure of Invention Problems to be solved by the invention Side mirrors used in trucks and the like are easily large and susceptible to traveling wind. This causes noise (wind noise) and deterioration of fuel economy. From the viewpoint of noise suppression and improvement of fuel economy, it is effective for trucks and the like to use digital side mirrors that are easily miniaturized as compared with side mirrors. In a flathead vehicle such as a truck or a one-box car (one-box car) in which an engine hood is not provided in the front portion of the cab and an engine compartment is provided below a seat in the front portion, it tends to be difficult to see below the front portion of the cab when viewed from the driver's seat. In particular, it is difficult to see the front side of the passenger seat and the lower side of the side portion from the driver seat. In view of the above, when a digital side mirror is mounted on a flat-head vehicle such as a truck, it is desirable to set each of the driver's seat side and the passenger's seat side of the cab within an imaging range. In addition, a camera for a digital side mirror may be provided in an imaging range not only to capture an image of the outside of the vehicle but also for the purpose of monitoring the driver. In order to set the position of the camera so as to satisfy various imaging ranges, it is conceivable to make the structure of the digital side mirror different between the driver seat side and the passenger seat side. However, when the structure of the digital side mirror is made different between the driver's seat side and the passenger's seat side, disturbance in aerodynamic resistance is likely to occur. In particular, there is a concern about adverse effects during high-speed running. As described above, in the conventional technology, there is room for improvement in terms of both securing the imaging range of the camera for the digital side mirror and improving the aerodynamic force. The present application has been made in view of the above-described problems, and an object thereof is to provide a digital side mirror structure capable of achieving both of securing an imaging range of a camera for a digital side mirror and improving aerodynamic force. Means for solving the problems The present application has been made to solve at least some of the above problems, and can be implemented as the following aspects or application examples. (1) The digital side mirror structure of the present application example is a digital side mirror structure disposed in front of a driver's seat in a vehicle body of a vehicle, and includes a first digital side mirror disposed on one side in a vehicle width direction, which is a driver's seat side, in the vehicle body, and a second digital side mirror disposed on the other side in the vehicle width direction, which is a passenger's seat side, in the vehicle body. The first digital side mirror includes a first lateral support portion that extends from one side in the vehicle width direction toward the outside in the vehicle width direction at an upper edge portion of a front panel disposed below a front window glass in a front surface portion of the vehicle body, a first longitudinal support portion that is provided to stand upward from a distal end portion of the first lateral support portion, and a first attachment portion that is connected to an upper end portion of the first longitudinal support portion and that holds a first electronic imaging device for imaging a first imaging range around the vehicle including one side in the vehicle width direction. The second digital side mirror includes a protruding portion protruding from the other side in the vehicle width direction toward the front of the vehicle at the upper edge portion of the front panel in the front surface portion of the vehicle body, a second lateral
