Accordingly, the drawings and description are to be regarded as illustrative in nature and not as restrictive.

A rearview device according to an embodiment of the present application is described below with reference to fig. 1 to 9.

Fig. 1 shows a schematic structural diagram of a rearview device according to an embodiment of the present application. As shown in fig. 1, the rearview apparatus for a vehicle according to an embodiment of the present application includes an image pickup device (not shown in the drawings) and a display device 100. Specifically, the image pickup device is provided outside the vehicle body of the vehicle for picking up a rear side image of the vehicle. The display device 100 is arranged at the front side of the main driving seat of the vehicle, and the display device 100 is electrically communicated with the image acquisition device and is used for receiving and displaying the rear side image; wherein the horizontal field angle α of the display area 101 of the display device 100 with respect to the point of view of the driver at front view is less than or equal to 60 degrees.

In the embodiment of the present application, the image capturing device may include at least one camera, and the embodiment of the present application is not particularly limited as to the type of the camera, as long as the capturing requirement for the image on the rear side of the vehicle can be satisfied. The specific location of the image capturing device on the vehicle body is not particularly limited in this embodiment of the present application. For example, the image capturing device may include two cameras respectively disposed on left and right sides of the vehicle body, and the two cameras are respectively disposed toward left and right rear sides of the vehicle body to respectively capture left and right rear side images of the vehicle. The display device 100 is in electrical communication with the image capture device for receiving image data captured by the image capture device and displaying the image data in a corresponding display area 101. The display device 100 may use any type of display method, for example, the display device 100 may use an electronic display screen to display an image, or may use a projection method to display an image in a designated area.

The angle of view of the display area 101 of the display device 100 is also referred to as a field of view in optical engineering, and the size of the angle of view determines the field of view of the optical instrument. In a display system, the field angle is the angle between the edge of the display and the line of sight 600 (the eye). In particular, the horizontal viewing angle α of the display area 101 may be understood as an angle between the driver's viewpoint 600 and a horizontal line connecting two opposite sides of the display area 101 in the horizontal direction.

The driver's point of view when looking forward can be understood as the position of the eyes when the driver is in the driving posture and in front of the front view when seated in the main driving seat. For example, the driver's point of view may be the location of the center point of the primary drive seat headrest or the location of the driver's eyepoint.

In the embodiment of the present application, the installation position of the display device 100 on the vehicle body is not particularly limited, and may be, for example, installed on the instrument desk 200 of the vehicle or may be installed on the top wall of the vehicle body by hoisting.

It will be appreciated that the ergonomic recommended horizontal viewing angle may be 60 degrees in visual range, with an optimal range of 30 degrees, as shown in fig. 2. Compared with the prior art that display screens are arranged on two door bodies or two A columns on the left side and the right side of a vehicle body to respectively display left rear side images and right rear side images, the rearview device in the embodiment of the application can directly observe the left rear side images and the right rear side images without turning left and right when a driver observes the display area 101 by setting the horizontal field angle alpha of the display area 101 to be less than or equal to 60 degrees, so that time difference caused by visual focusing in the turning process is reduced, and further the use experience and driving safety are improved.

In one embodiment, the horizontal field angle of the display area 101 is less than or equal to 50 degrees; or the horizontal field angle of the display area 101 is less than or equal to 40 degrees; or the horizontal viewing angle of the display area 101 is less than or equal to 30 degrees.

In the embodiment of the present application, the size of the display area 101 in the horizontal direction and the distance from the main driving seat in the front-rear direction may be specifically set according to the actual situation, as long as the horizontal viewing angle α of the display area 101 is satisfied to be less than or equal to 50 degrees, 40 degrees, or 30 degrees.

In one embodiment, an angle between a projection of an extension direction of a line connecting a horizontal center point of the display area 101 and a horizontal center point of the main seat on a horizontal plane and a front-rear direction of the vehicle body is less than or equal to 20 degrees.

In the embodiment of the application, the front-rear direction refers to the longitudinal direction (i.e., the X-axis direction) of the vehicle. The horizontal center point of the display area 101 refers to the horizontal center point of the display area 101 in the lateral direction of the vehicle (i.e., the Y-axis direction), and the horizontal center point of the main seat refers to the horizontal center point of the display area 101 in the lateral direction of the vehicle.

By the above embodiment, the horizontal center point of the display area 101 can be arranged to be opposite to the horizontal center point of the main driving seat as much as possible, so that the position of the display area 101 is located in the range of the front view of the driver as much as possible, and the display area 101 can be observed by the driver without turning left and right.

Preferably, the projection of the extending direction of the line connecting the horizontal center point of the display area and the horizontal center point of the main seat in the horizontal plane is parallel to the front-rear direction of the vehicle body. In other words, the position of the horizontal center point of the display area 101 is disposed directly opposite to the position of the horizontal center point of the main drive seat in the front-rear direction.

Although the position of the horizontal center point of the display area 101 and the position of the horizontal center point of the main driving seat are set in correspondence in the front-rear direction, the position of the horizontal center point of the display area 101 and the position of the horizontal center point of the main driving seat may or may not be set in correspondence in the up-down direction (the vertical direction of the vehicle, i.e., the Z-axis direction), that is, the position of the horizontal center point of the display area 101 and the position of the horizontal center point of the main driving seat may be located at the same height or at different heights.

According to the embodiment, the position of the horizontal center point of the display area 101 and the position of the horizontal center point of the main driving seat are arranged in the front-rear direction, so that the display area 101 can be positioned right in front of the driver, and the driver can observe the left rear side image and the right rear side image displayed by the display area 101 only by looking right in front without turning the head in the driving process, thereby further improving the driving safety and convenience.

For example, the vehicle body domain control module may generate a corresponding automatic control instruction according to a detection result of the eye movement of the driver or a detection result of the sun sensor, so as to control the driving module to drive the display device 100 to move, thereby implementing automatic adjustment of the first sub-display area 100a and/or the second sub-display area 100b, and further improving the driving experience.

In one embodiment, as shown in fig. 9, the display device 100 includes a projection module 40, and the projection module 40 is configured to project on a front windshield 400 of a vehicle to form a first sub-display area 100a and a second sub-display area 100b.

In an embodiment of the present application, the projection module 40 may employ a HUD (Head Up Display) system. Illustratively, the projection module 40 is mounted to a roof panel 500 of a center console of the vehicle to enable the projection module 40 to project light toward a front windshield 400 of the vehicle. The projection module 40 may include a first projection unit 41 and a second projection unit 42, the first projection unit 41 and the second projection unit 42 being disposed at intervals in a horizontal direction to project on a front windshield 400 of the vehicle to form a first sub-display area 100a and a second sub-display area 100b, respectively.

Through the above embodiment, the height positions of the first sub-display area 100a and the second sub-display area 100b can be as close as possible to the position of the observation point 600 of the driver, so that the driver can directly observe the pictures of the first sub-display area 100a and the second sub-display area 100b in the head-up state without lowering or tilting the head, and the driver can not be influenced to observe the road conditions ahead through the front windshield 400 through the projection display, thereby further improving the driving experience of the driver.

In one embodiment, the front windshield 400 has a designated area, which may be disposed adjacent to the lower edge of the front windshield 400; the appointed area is used for setting an imaging film group, and the imaging module is used for displaying a projection image of the projection module.

Illustratively, the imaging film set includes a light transmissive film layer and a reflective film layer disposed in a stack. It will be appreciated that the reflective layer has a high reflectivity and reflects the projected image above the driver's line of sight. The light-transmitting film has a high transparency, ensuring that the driver can see the projected image through the film.

The projection module projects the image acquired by the image acquisition device onto the reflective film layer through the light source. The light source may be an LED or a laser, etc. When the projected light encounters the reflective layer, the light is reflected above the driver's line of sight due to the high reflectivity of the reflective film layer.
