For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0039] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0040] refer to Figure 1-Figure 4 , the present application provides a rearview mirror, comprising:

[0041] A rearview mirror body 100, wherein a light outlet 110 is provided on a lower surface of the rearview mirror body 100;

[0042] The projection mechanism 200 is disposed inside the rearview mirror body 100 , and the projection light head 210 of the projection mechanism 200 is opposite to the light outlet 110 and faces downward of the rearview mirror body 100 ;

[0043] The projection mechanism 200 is configured to direct the projection light head 210 toward the bottom and / or lower rear of the rearview mirror body 100 to project the display image to the first target area 400 directly below the vehicle side rearview mirror and / or the second target area 500 below and behind the rearview mirror.

[0044] Specifically, the lower area of ​​the rearview mirror is partially designed as a light outlet 110, and the projection light emitted by the projection mechanism 200 is emitted from the projection light head 210 and projected from the light outlet 110 on the lower surface of the rearview mirror body 100, and is projected on the target area on the ground beside the vehicle, forming a projection image on the ground (such as Figure 3 , Figure 4 ).

[0045] like Figure 4 The specific position of the ground projection can be moved from the first target area 400 directly below the rearview mirror to the second target area 500 at the rear door under the rearview mirror according to the design of the optical machine lens. The shape of the projection area can be circular, rectangular, or trapezoidal; the projection color can be black and white or colorful, and the size of the projection target area can also be different according to the design of the projection mechanism 200.

[0046] like Figure 5 , the ground projection target area can display different contents according to different usage scenarios. For example:

[0047] Scenario 1: When the driver approaches the vehicle 10 (or locks the vehicle), the vehicle 10 detects a signal and displays "Welcome Mr. / Ms. XXX" (or displays "Goodbye, Mr. / Ms.") on the ground in the first target area 400 directly below the rearview mirror through surround projection technology, creating a welcoming effect / farewell effect and increasing the interaction between the driver and the vehicle. The display content, text, pattern, etc. can be customized for the vehicle.

[0048] Scenario 2: When the passenger approaches the vehicle, the vehicle 10 detects a signal and displays today's weather, unread messages, real-time news, today's itinerary, etc. on the second target area 500 below and behind the rearview mirror through surround projection technology; before the driver and passengers get on the vehicle, a message "Please pay attention to your feet" can be displayed as a reminder;

[0049] In scenario three, when the vehicle 10 encounters a breakdown or an emergency, the vehicle start / stop information can be displayed in real time through surround projection technology. For example, "The vehicle has started, pay attention to avoid" is displayed on the ground in the second target area 500 behind the rearview mirror to facilitate rescue or remind surrounding pedestrians / objects to avoid.

[0050] Of course, the actual application scenarios of projection are not limited to the above scenarios. It is diverse and customizable as long as it can be applied to human-vehicle interaction.

[0051] In this embodiment, the projection mechanism 200 is mounted on the side of the vehicle 10, and the surround projection technology outside the vehicle is used to form the interaction on both sides of the vehicle. The off-vehicle projection technology of this application fills the gap in the interactive technology on both sides of the vehicle. It can project real-time color images, text, animations or pre-stored information in the cloud onto the ground on the side of the vehicle. The display strategy can be changed according to whether the object is the driver, passenger or surrounding pedestrians (different display area positions and display contents are selected), and the latest vehicle status can be displayed to relevant personnel in real time, so that people and vehicles can form better communication; it can also convey the real-time situation of the vehicle to passing vehicles or people, and deal with various emergencies. This new type of off-vehicle projection technology will be an important part of the future development of automotive intelligence.

[0052] It is worth pointing out that the projection mechanism 200 is a projection optical machine assembly, such as a conventional projection device. To improve the use effect, DLP (Digital Light Processing) can be selected. DLP is a technology based on the digital micromirror device DMD (Digital Micromirror Device) developed by TI (Texas Instruments) to display visual digital information, and has a better display effect.

[0053] The rearview mirror of the car is not sealed, and the projection mechanism 200 is not self-sealing. Therefore, when used in a harsh environment, water vapor, dust, etc. can easily enter the interior of the rearview mirror through the gap between the two and cause damage to the projection mechanism 200. Figure 2 and Figure 6 In some embodiments, the rearview mirror further includes: a sealing cover structure 300, which is disposed in the rearview mirror body 100, and the periphery of the sealing cover structure 300 is sealed and connected to the rearview mirror body 100; the projection mechanism 200 is accommodated in the sealing cover structure 300, and the lower part of the sealing cover structure 300 is provided with a transparent cover head 330 for the projection light of the projection light head 210 to pass through.

[0054] In this embodiment, the sealing cover structure 300 (such as Figure 2 ) is closely connected to the rearview mirror body 100, and there is no gap between the two, so that water vapor, dust, etc. cannot enter the interior of the rearview mirror from between the two, thereby isolating the damage source; at the same time, the projection mechanism 200 is accommodated in the sealing cover structure 300 and protected, further ensuring that the projection mechanism 200 will not be damaged by contact with foreign objects, thereby ensuring the normal use stability of the projection mechanism 200 (see the sealing cover for details) Figure 6 ).

[0055] refer to Figure 6 In some embodiments, the sealing cover structure 300 includes:

[0056] A cover 310 is disposed around the projection mechanism 200;

[0057] A top sealing plate 320 is disposed on the top of the cover body 310 and connected to the top edge of the cover body 310;

[0058] The light-transmitting cover head 330 is disposed at the bottom of the cover body 310 and connected to the bottom edge of the cover body 310 , and is used for allowing the projection light of the projection light head 210 to pass downward.

[0059] Specifically, the cover body 310, the top sealing plate 320, and the transparent cover head 330 form a closed space, which can protect the projection mechanism 200 therein and ensure that the projection mechanism 200 will not be damaged by contact with foreign objects; the transparent cover head 330 is made of a transparent material, and the projection light of the light head 210 can pass downward from the transparent cover head 330 and be projected normally on the ground.

[0060] refer to Figure 6 In some embodiments, the light-transmitting cover head 330 and the cover body 310 are double-color injection molded. Double-color injection molding can completely prevent the formation of a gap between the light-transmitting cover head 330 and the cover body 310, and the sealing effect is better.

[0061] refer to Figure 6 In some embodiments, the transparent cover head 330 is sealed with the edge of the cover body 310 by waterproof glue. The waterproof glue can block the gap between the cover body 310 and the transparent cover head 330 to ensure that dust and the like will not enter the interior through the gap to damage the projection mechanism 200.

[0062] In some embodiments, the transparent cover head 330 is optical glass. Of course, the transparent cover head 330 can also be made of other transparent materials, which is not limited here.

[0063] refer to Figure 4 The present application also discloses a vehicle, the side of which is provided with the rearview mirror.

[0064] The side of the vehicle 10 of this embodiment is provided with a projection mechanism 200, and the surround projection technology outside the vehicle is used to form the interaction on both sides of the vehicle. The vehicle-side projection technology of this application fills the gap of the interactive technology on both sides of the vehicle, and can project the real-time color images, texts, animations or pre-stored information of the vehicle computer from the cloud onto the ground of the vehicle side, and change the display strategy (select different display area positions and display contents) according to whether the object is the driver, passenger or surrounding pedestrians, and show the latest vehicle status to relevant personnel in real time, so as to form better communication between people and vehicles; it can also convey the real-time situation of the vehicle to passing vehicles or people, and deal with various emergencies. This new type of vehicle-side projection technology will be an important part of the future development of automobile intelligence.

[0065] The above-mentioned means of transportation may be a car, a train, a high-speed train or other means of transportation that requires headlights.

[0066] refer to Figure 4 In some embodiments, a distance W between a side edge of the first target area 400 and / or the second target area 500 close to the vehicle 10 and the side edge of the vehicle 10 is 150 to 300 mm.

[0067] It has been verified that when the distance W between the edge of one side of the target area close to the vehicle and the side of the vehicle is less than 150mm, it is too close to the side of the vehicle, and the projected image will be partially projected onto the edge of the side of the vehicle, and the display will be incomplete, and the desired effect will not be achieved; when the distance W between the edge of one side of the target area close to the vehicle and the side of the vehicle is greater than 300mm, too much public area will be occupied, affecting traffic safety.

[0068] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.

[0069] It will be apparent to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above, and that the present application can be implemented in other specific forms without departing from the spirit or essential features of the present application. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the present application is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present application.
