Detailed Description
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
In the present disclosure, unless otherwise specified, use of directional words such as "upper and lower" are generally defined in the direction shown in fig. 3, and "inner and outer" refer to the inner and outer of the corresponding structure or component outline, but those skilled in the art will appreciate that the above directional words are used only for explaining and explaining the present disclosure, and are not used for limitation. Furthermore, terms such as "first," "second," and the like, are used herein to distinguish one element from another, and are not necessarily sequential or significant.
As shown in fig. 1 to 4, the present disclosure provides a vehicle instrument panel, including an instrument panel body 1, a display screen 2, a camera 3, and a invisible light emitter 4, the display screen 2 and the camera 3 are both installed on the instrument panel body 1, and the camera 3 is located below the display screen 2, the display screen 2 is configured to be able to transmit invisible light, the invisible light emitter 4 is used for emitting invisible light irradiating passengers in the vehicle, and the camera 3 is used for receiving invisible light reflected by the passengers and passing through the display screen 2, so as to collect image information of the passengers. Here, the camera 3 being located below the display screen 2 means that the camera 3 is located on the side of the display screen 2 close to the vehicle head when the vehicle dashboard is mounted on the vehicle, i.e. the display screen 2 is located between the camera 3 and the passenger compartment, so that the display screen 2 can obscure the camera 3.
Because camera 3 is located the below of display screen 2, when vehicle instrument panel installs on the vehicle, display screen 2 can shelter from, hide camera 3 to make camera 3 can not expose inside the vehicle, thereby can gather passenger's image information, can avoid camera 3 to occupy the inside space of vehicle again, influence the inside pleasing to the eye degree of vehicle. The image information collected by the camera 3 can be used for in-vehicle payment to realize non-sensitive payment on a highway, or non-sensitive payment in a gas station, and the like. The image information collected by the camera 3 can also be used for monitoring the physical sign condition of the driver, for example, when the image information collected by the camera 3 represents fatigue driving of the driver, the vehicle can prompt the driver to stop for a rest. For the shared traveling vehicle, the image information collected by the camera 3 can also be used for verifying whether the driver actually driving the vehicle is consistent with the registered driver, so that the safety of passengers in the vehicle is ensured.
In addition, because the display screen of the vehicle dashboard usually needs to display the operating condition information of each system of the vehicle, for example, information such as fuel amount, vehicle speed, and engine speed, the operating condition information is usually displayed by using visible light (light with a wavelength between 380nm and 780 nm) that can be perceived by human eyes, so that the driver can view the operating state of each system of the vehicle at any time. In order to avoid the influence of the position of the camera 3 on the normal display of the display screen 2, that is, in order to enable the projection area of the camera 3 on the display screen 2 to normally display images, when the image information of passengers is collected in the present disclosure, the invisible light emitter 4 is used to emit invisible light (light with a wavelength less than 380nm or greater than 780 nm) which is not perceivable by human eyes to passengers in the vehicle, and the camera 3 receives the invisible light emitted by passengers in the vehicle to collect the image information of the passengers, because the human eyes cannot sense the invisible light, the purpose of not influencing the display effect of the display screen 2 is achieved, that is, when the human eyes check the display screen 2, the projection area of the camera 3 on the display screen 2 can also display images.
Further, in an embodiment provided by the present disclosure, as shown in fig. 3, the display screen 2 includes a display layer 21 and a backlight layer 22, the backlight layer 22 is located between the display layer 21 and the instrument panel main body 1, a first opening 221 is formed in the backlight layer 22, the camera 3 passes through the first opening 221 and is located below the display layer 21, and the display layer 21 is made of a material capable of transmitting visible light and invisible light, so that the camera 3 can receive the invisible light reflected by a passenger in the vehicle without destroying the display function of the display layer 21. Because the backlight layer 22 is provided with the first opening 221 through which the camera 3 passes, the camera 3 is located below the display layer 21, and when the invisible light passes through the display screen 2, the invisible light only needs to pass through the display layer 21 of the display screen 2, so that attenuation of the invisible light is effectively reduced, and image quality of image information acquired by the camera 3 is improved. And, because the invisible light does not need to pass through the backlight layer 22, the backlight layer 22 is allowed to be made of the material which can transmit the invisible light, and the manufacturing cost of the display screen 2 is reduced.
In other embodiments, the camera may be located below the backlight layer, and both the display layer and the backlight layer are made of materials that can transmit visible light. Alternatively, the projection areas of the camera on the display layer and the backlight layer are made of a material that can transmit visible light. Here, the material that can transmit visible light may be glass or the like.

The light guide layer 222 may be made of a material capable of transmitting visible light, and the light reflection layer 223 may be made of a material capable of reflecting visible light, so that the light guide layer 222 may allow visible light emitted from a backlight of the display screen 2 to pass through, thereby enabling the light reflection layer 223 to reflect the visible light onto the display layer 21. For embodiments in which the camera 3 is disposed below the backlight layer 22, the light guide layer 222 may be made of a material that is transmissive to visible light and invisible light, and the light reflecting layer 223 may be made of a material that is transmissive to invisible light and reflective to visible light.
