Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to an in-vehicle display and interaction device and a vehicle. Background Technology

[0002] With the upgrading of automobiles towards electrification and intelligence, the application and deployment of cameras in the cockpit are increasing. For example, in-vehicle cameras can be deployed to capture information such as the driver's facial expressions and eye state, enabling early warnings of conditions such as fatigued driving; or, in-vehicle cameras can be deployed to capture the driver's hand gestures, enabling intelligent human-vehicle interaction through gesture control.

[0003] However, in-cabin cameras take up some space and also affect the simplicity and aesthetics of the vehicle's interior. Utility Model Content

[0004] This application provides an in-vehicle display and interaction device and a vehicle, which aims to improve the problem of poor simplicity and aesthetics of the vehicle interior caused by the installation of in-vehicle cameras.

[0005] The specific technical solution is as follows:

[0006] In a first aspect, embodiments of this application propose an in-vehicle display interaction device. The in-vehicle display interaction device includes: a display screen; a rear shell connected to the display screen, the display screen and the rear shell forming a receiving cavity, the bottom or top of the rear shell having a light guide channel extending along the thickness direction of the display screen, the light guide channel communicating with the receiving cavity; a first camera disposed within the receiving cavity with its light incident surface close to the light guide channel; and a light guide member disposed within the light guide channel, the light guide member being configured to guide interior light into the first camera.

[0007] The in-vehicle display and interaction device of this application has a first camera disposed within its housing cavity. The first camera can acquire images of the vehicle interior through a light guide channel and light guide components. This arrangement allows for the placement of the first camera using existing components within the vehicle, preventing the camera from being exposed and occupying interior space, thereby improving the aesthetics and simplicity of the vehicle interior. Furthermore, the housing cavity also provides protection for the first camera, thus contributing to an increase in its lifespan and reliability.

[0008] In some embodiments, the light guide is one of a reflector, a light guide plate, or a prism. Reflectors, light guide plates, and prisms can all deflect light within the light guide channel, enabling folded propagation of light within a limited space, thereby improving the reliability and stability of image acquisition by the first camera.

[0009] In some embodiments, the rear shell has a first mating surface which is attached to the display screen, and the end surface of the light guide channel close to the display screen is not more than the first mating surface. In this way, on the one hand, the light guide channel is not too long, which can limit the light acquisition, thereby improving the reliability and stability of the image acquisition of the first camera. On the other hand, the light guide channel does not protrude from the display screen, thereby improving the appearance of the vehicle display interaction device.

[0010] In some embodiments, the vehicle display interaction device further comprises a first optical element arranged between the light guide and the first camera, and the first optical element is used for converging light. In this way, the amount of light entering the first camera can be further improved, thereby improving the imaging effect and quality of the first camera.

[0011] In some embodiments, the vehicle display interaction device further comprises a second optical element arranged on the side of the light entrance surface of the light guide, and the second optical element is used for converging light. In this way, the amount of light entering the light guide can be further improved, thereby improving the light guide efficiency of the light guide, and further improving the imaging effect and quality of the first camera.

[0012] In some embodiments, along the extension direction of the light guide channel, the width of the light guide channel gradually increases towards the display screen. In this way, more indoor light can enter the light guide channel and be guided to the first camera through the light guide, reducing light loss, thereby further improving the imaging effect and quality of the first camera.

[0013] In some embodiments, the inner wall of the light guide channel is provided with a reflective microstructure, and the reflective microstructure is configured to guide light into the light guide. The reflective microstructure can effectively capture and reflect light from different directions, so that more light is reflected into the light guide. In this way, the collection efficiency of light can be further improved, thereby further improving the imaging effect and quality of the first camera.

[0014] In some embodiments, the vehicle display interaction device further comprises a first circuit board arranged in the accommodating cavity, and the first circuit board is electrically connected with the display screen and the first camera. That is, in addition to realizing the vehicle display function related to itself, the vehicle display interaction device can also realize the display of the indoor picture. In this way, on the one hand, it is beneficial to improve the functional diversity and intelligence of the vehicle display interaction device. On the other hand, it is also beneficial to improve the convenience of electrical connection of the first camera.

[0015] In some embodiments, the first camera comprises a lens module, an image sensor and a second circuit board, the lens module and the second circuit board are connected with the rear shell, the image sensor is located on one side of the light exit surface of the lens module and connected with the second circuit board, and the second circuit board is electrically connected with the first circuit board. In this embodiment, the first camera is composed of multiple separate components, each component can be flexibly designed according to actual conditions, which reduces the probability of interference between the first camera and the accommodating cavity, thereby facilitating the flexibility and convenience of the arrangement of the first camera.

[0016] In some embodiments, the vehicle-mounted display interaction device is one of a streaming rearview mirror and a central control screen. In this embodiment, the first camera is arranged in the accommodating cavity of the streaming rearview mirror or the central control screen, and the arrangement of the first camera can be realized by using the above components, thereby facilitating the aesthetic and simplicity of the vehicle interior, and improving the service life and reliability of the first camera.

[0017] In a second aspect, the application provides a vehicle comprising the vehicle-mounted display interaction device of the first aspect, which is installed in the cabin of the vehicle.

[0018] The vehicle of the application is provided with a vehicle-mounted display interaction device, and the accommodating cavity of the vehicle-mounted display interaction device is provided with a first camera. The first camera can obtain the in-vehicle picture through the light guide piece and the light guide channel. In this way, the arrangement of the first camera can be realized by using the existing component structure in the vehicle, and the first camera will not be exposed to occupy the space in the vehicle, thereby facilitating the aesthetic and simplicity of the vehicle interior.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0030] As described in the background, under the wave of automobile electrification and intelligentization, the application and arrangement of in-cabin cameras are more and more. If the in-vehicle camera is directly arranged in the cabin, it will occupy a certain space in the vehicle, and at the same time will affect the simplicity and aesthetics of the vehicle interior.

[0031] Therefore, the embodiment of the present application proposes a vehicle-mounted display interaction device 10, aiming to improve the problem of poor simplicity and aesthetics of the interior of the whole vehicle caused by the increase in the number of in-vehicle cameras.

[0032] As shown in Figure 1 and Figure 2 , in the first aspect, the present application proposes a vehicle-mounted display interaction device 10. The vehicle-mounted display interaction device 10 comprises a display screen 100, a rear shell 200, a first camera 300, and a light guide piece 400. The rear shell 200 is connected with the display screen 100, and the display screen 100 and the rear shell 200 enclose a containing cavity 101. The bottom or top of the rear shell 200 is provided with a light guide channel 201 extending along the thickness direction of the display screen 100. The light guide channel 201 is in communication with the containing cavity 101. The first camera 300 is arranged in the containing cavity 101 and the light entrance surface thereof is close to the light guide channel 201. The light guide piece 400 is arranged in the light guide channel 201, and the light guide piece 400 is configured to guide the in-vehicle light into the first camera 300.

[0033] The display screen 100 can display a picture to realize human-computer interaction. Generally, the vehicle-mounted display interaction device 10 is also provided with physical buttons 10a for controlling the switching, turning on, and turning off of the display picture. The display screen 100 generally comprises a cover plate and a display module. The cover plate is arranged on the light exit side of the display module to form protection for the display module. The display module can be one of a liquid crystal display module, a light-emitting diode display module, and an organic light-emitting diode display module.

[0034] The rear shell 200 can realize the mounting and fixing of the display screen 100. The first camera 300 is arranged in the containing cavity 101 formed by the rear shell 200 and the display screen 100. Moreover, the bottom or top of the rear shell 200 is provided with the light guide channel 201. The specific arrangement position of the light guide channel 201 is determined according to the mounting position of the vehicle-mounted display interaction device 10 in the vehicle. If the mounting height of the vehicle-mounted display interaction device 10 is too low, the light guide channel 201 can be arranged at the top of the rear shell 200. If the mounting height of the vehicle-mounted display interaction device 10 is moderate or relatively high, the light guide channel 201 can be arranged at the bottom of the rear shell 200. In this way, the light guide channel 201 has a good in-vehicle view.

[0035] The light guide piece 400 is arranged in the light guide channel 201. The light guide piece 400 can guide the light entering the light guide channel 201 into the first camera 300, so that the first camera 300 can obtain the in-vehicle picture in real time. The first camera 300 can be the cockpit camera described in the related art. The in-vehicle picture can be, for example, the facial expression, gesture action of the driver, the state of the passenger in the vehicle, and the environment in the vehicle.

[0036] The light entrance surface of the first camera 300 is close to the light guide channel 201, that is, the first camera 300 is vertically placed, and the optical axis of the first camera 300 extends along the height direction of the vehicle. In this way, the arrangement of the first camera 300 can be realized while ensuring the thinness of the vehicle display interactive device 10.

[0037] The vehicle display interactive device 10 of the present application is provided with the first camera 300 in the accommodating cavity 101. The first camera 300 can acquire the in-vehicle picture through the light guide member 400 and the light guide channel 201. In this way, the arrangement of the first camera 300 can be realized by using the existing display components in the vehicle, and the first camera 300 will not be exposed to occupy the space in the vehicle, thereby facilitating the improvement of the aesthetics and simplicity of the vehicle interior. In addition, the accommodating cavity 101 can also protect the first camera 300, thereby facilitating the improvement of the service life and reliability of the first camera 300.

[0038] In some embodiments, the vehicle display interactive device 10 is one of a streaming rearview mirror and a central control screen. The streaming rearview mirror refers to a display device that combines an external camera with a traditional in-vehicle rearview mirror, which can display the picture taken by the external camera, effectively reduce the blind area, and improve the driving safety. The central control screen is an intelligent interactive display screen in the vehicle, which can realize various vehicle instructions, such as displaying vehicle information, navigation information, multimedia information, etc.

[0039] In the present embodiment, the first camera 300 is arranged in the accommodating cavity 101 of the streaming rearview mirror or the central control screen, and the arrangement of the first camera 300 can be realized by using the above-mentioned components, thereby facilitating the improvement of the aesthetics and simplicity of the vehicle interior, and also facilitating the improvement of the service life and reliability of the first camera 300.

[0040] It can be understood that, as shown in Figure 2 If the vehicle display interactive device 10 is a streaming rearview mirror, the light guide channel 201 is preferably arranged at the bottom of the rear shell 200 of the streaming rearview mirror. In this way, the height of the light guide channel 201 in the vehicle is appropriate, and a larger field of view can be acquired. If the vehicle display interactive device 10 is a central control screen, the light guide channel 201 is preferably arranged at the top of the rear shell 200 of the central control screen. In this way, the height of the light guide channel 201 in the vehicle is also appropriate, and a larger field of view can be acquired.

[0041] In some embodiments, the light guide member 400 is one of a mirror, a light guide plate, and a prism. The mirror, the light guide plate, and the prism can all realize the deflection of light in the light guide channel 201, and realize the folded propagation of the light path in a limited space, thereby facilitating the improvement of the reliability and stability of the image acquisition of the first camera 300.

[0042] Preferably, the light guide 400 is a mirror, which has low cost and simple optical path design.

[0043] In some embodiments, as shown in Figure 2 The rear shell 200 has a first matching surface 210 abutting the display screen 100, and the end surface of the light guide channel 201 close to the display screen 100 is not more than the first matching surface 210.

[0044] That is, the end surface of the light guide channel 201 close to the display screen 100 can be flush with the first matching surface 210, for example, the end surface of the light guide channel 201 close to the display screen 100 is flush with the surface of the key 10a; or, the light guide channel 201 has a certain distance from the first matching surface 210, and the light guide channel 201 is recessed.

[0045] In this way, on the one hand, the light guide channel 201 can be prevented from being too long, which limits the acquisition of light, thereby improving the reliability and stability of the image acquisition of the first camera 300. On the other hand, the light guide channel 201 does not protrude from the display screen 100, thereby improving the aesthetics of the vehicle-mounted display interaction device 10.

[0046] In some embodiments, as shown in Figure 3 The vehicle-mounted display interaction device 10 further includes a first optical element 500 arranged between the light guide 400 and the first camera 300, and the first optical element 500 is used for converging light. In this way, the amount of light entering the first camera 300 can be further improved, thereby improving the imaging effect and quality of the first camera 300. Optionally, the first optical element 500 can be a convex lens, a Fresnel lens, etc., which is not limited in the present application.

[0047] In some embodiments, as shown in Figure 4 The vehicle-mounted display interaction device 10 further includes a second optical element 600 arranged on the light-incident surface side of the light guide 400, and the second optical element 600 is used for converging light. In this way, the amount of light entering the light guide 400 can be further improved, thereby improving the light guiding efficiency of the light guide 400, and further improving the imaging effect and quality of the first camera 300. Optionally, the second optical element 600 can be a convex lens, a Fresnel lens, etc., which is not limited in the present application.

[0048] In some embodiments, along the extension direction of the light guide channel 201, the width of the light guide channel 201 gradually increases towards the display screen 100. That is, the width of the light inlet of the light guide channel 201 is large. In this way, more indoor light can enter the light guide channel 201, and then be guided to the first camera 300 through the light guide 400, thereby reducing light loss, and further improving the imaging effect and quality of the first camera 300.

[0049] In some embodiments, such as Figure 2 As shown, the inner wall of the light guide channel 201 is provided with a reflective microstructure 220. The reflective microstructure 220 is configured to guide light into the light guide component 400. The reflective microstructure 220 can be, for example, a microprism structure, a sawtooth structure, or a concave-convex structure disposed on the inner wall of the light guide channel 201. The reflective microstructure 220 can effectively capture and reflect light from different directions, allowing more light to be reflected into the light guide component 400. In this way, the light collection efficiency can be further improved, which is conducive to further improving the imaging effect and quality of the first camera 300.

[0050] In some embodiments, such as Figure 2 As shown, the in-vehicle display and interaction device 10 also includes a first circuit board 700 disposed within the receiving cavity 101. The first circuit board 700 is electrically connected to both the display screen 100 and the first camera 300. The image captured by the first camera 300 can be transmitted to the display screen 100 through the first circuit board 700, so that the display screen 100 displays the in-vehicle scene.

[0051] In this embodiment, the in-vehicle display interaction device 10, in addition to realizing its own in-vehicle display functions, can also display in-vehicle images. This improves the functional diversity and intelligence of the in-vehicle display interaction device 10. Furthermore, it also enhances the convenience of the electrical connection of the first camera 300.

[0052] It should be noted that the display screen 100 of the vehicle display interaction device 10 of this application can realize the parallel display or serial display of the display screen of the first camera 300 and its own function screen through software screen splitting, button switching, etc., and this application does not limit this.

[0053] It is understood that the first camera 300 can be an existing commercial camera, or the structure of the first camera 300 can be designed separately. For example, in some embodiments, such as Figure 5 As shown, the first camera 300 includes a lens module 310, an image sensor 320, and a second circuit board 330. Both the lens module 310 and the second circuit board 330 are connected to the rear shell 200. The image sensor 320 is located on one side of the light-emitting surface of the lens module 310 and is connected to the second circuit board 330. The second circuit board 330 is electrically connected to the first circuit board 700.

[0054] The lens module 310 is used to acquire light transmitted from the light guide 400 and converge the light to the image sensor 320. The lens module 310 may include a lens barrel and multiple lenses disposed within the lens barrel, and the lens barrel may be fixed to the rear housing 200.

[0055] The image sensor 320 converts the light signal into an electric signal and transmits to the second circuit board 330. The image sensor 320 can be one of a CCD (Charge Coupled Device) image sensor, a CMOS (Complementary Metal-Oxide-Semiconductor) image sensor.

[0056] The second circuit board 330 is used to process the electric signal, and also transmits the processed signal to the first circuit board 700, so that the first camera 300 and the vehicle-mounted display interaction device 10 realize functional interaction.

[0057] In the embodiment, the first camera 300 is composed of a plurality of split components, and the specification of each split component can be flexibly designed according to actual conditions, thereby facilitating the reduction of the probability of the interference condition of the first camera 300 and the accommodating cavity 101, and further facilitating the flexibility and convenience of the arrangement of the first camera 300.

[0058] In a second aspect, the application provides a vehicle comprising the vehicle-mounted display interaction device 10 of the first aspect, and the vehicle-mounted display interaction device 10 is installed in the cabin of the vehicle.

[0059] The vehicle of the application uses the vehicle-mounted display interaction device 10 of the first aspect. The first camera 300 is arranged in the accommodating cavity 101 of the vehicle-mounted display interaction device 10. The first camera 300 can obtain the in-vehicle picture through the light guide channel 201 and the light guide piece 400. In this way, the arrangement of the first camera 300 can be achieved by borrowing the existing component structure in the vehicle, and the first camera 300 will not be exposed to occupy the space in the vehicle, thereby facilitating the aesthetic and simplicity of the interior of the vehicle.

[0060] In some embodiments, the vehicle-mounted display interaction device 10 is rotatably installed in the cabin. In this way, the light guide channel 201 can obtain the best field of view by rotating the vehicle-mounted display interaction device 10, thereby facilitating the further improvement of the imaging effect and quality of the first camera 300.

[0061] The above is only a specific embodiment of the application, but the protection scope of the application is not limited thereto, and any person skilled in the art can easily think of changes or replacements within the technical range disclosed in the application, which should be covered in the protection scope of the application. Therefore, the protection scope of the application should be subject to the protection scope of the claims.
