[0034] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0035] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0036] The applicant of this application found in the actual research process that with the development of the economy, vehicles have entered thousands of households. When the driver is driving the vehicle, the driver needs to view the relevant driving information of the vehicle in real time. At present, the display mode of vehicle driving information has gradually changed from traditional scales, numbers, pointers, traditional lights on and off, etc. to digital combination instrument panels and head-up display devices.

[0037] In the prior art, there are two types of head-up display devices (HUDs). One type of head-up display device projects driving information such as speed and navigation onto the windshield in front of the driver, so that the driver can see important driving information such as speed and navigation through the windshield, avoiding the driver from looking down to check the driving information of the vehicle while driving. The other type of head-up display device installs a display device on the center console of the vehicle, and the display device is used to display relevant vehicle driving information. When the driver's eyes move between the scenery in front of the vehicle and the displayed information, the driver's eyes do not need to focus back and forth frequently.

[0038] However, when the head-up display device displays the vehicle's driving information on the windshield, the vehicle needs to be equipped with a customized windshield and a high-precision projection device according to the size and curvature of the windshield. Therefore, projecting the vehicle's driving information onto the windshield requires advanced optical and electronic technologies, which leads to higher costs. If the vehicle's windshield is an ordinary windshield, the reflected imaging will produce obvious ghosting, resulting in unclear images projected onto the windshield, which can easily cause visual fatigue to the driver and endanger safe driving.

[0039] When the head-up display device is installed on the center console of the vehicle, the controller and the display device of the head-up display device are integrated and installed just in front of the steering wheel. The controller is hidden inside the center console. When turned on, the display device rises above the center console and the vehicle's driving information is projected onto the display device. However, such a head-up display device usually requires relatively more structural space, while the space between the vehicle's windshield and the center console is limited, which restricts the installation of the head-up display device.

[0040] In view of this, an embodiment of the present application provides a head-up display device and a vehicle, wherein the head-up display device includes a mounting base, a projection component and a display component, and the display assembly includes a display component and a connecting component. By setting the display component, the driver can view the vehicle's driving information in real time through the display component with the display surface facing the driver's seat, and the driver does not have to adjust his eyes between observing the distant road and the nearby instruments, thereby avoiding the driver's attention from being distracted from observing the road ahead, avoiding the driver's eye fatigue, improving the driver's driving safety, and rationally utilizing the space between the vehicle's windshield and the center console; by setting a coating component on the side of the display component away from the driver's seat, the imaging effect of the display component is improved; by setting a light blocking component on the vehicle's windshield, along the direction of the display surface, the projection of the display component on the surface where the light blocking component is located at least partially overlaps with the light blocking component, so that the light blocking component can be used as the background of the display component, and at the same time the light blocking component can also block the display component, thereby improving the neatness of the vehicle's appearance; the vehicle is provided with the above-mentioned head-up display device, which improves the vehicle's intelligence level.

[0041] In order to make the purpose, technical scheme and advantages of the present application clearer, the technical scheme in the embodiment of the present application will be described in more detail below in conjunction with the drawings in the preferred embodiments of the present application. In the drawings, the same or similar reference numerals throughout represent the same or similar parts or parts with the same or similar functions. The described embodiments are part of the embodiments of the present application, not all of the embodiments. The embodiments described below with reference to the drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limitations on the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application. The embodiments of the present application are described in detail below in conjunction with the drawings.

[0042] In a first aspect, the present application provides a head-up display device for projection inside a vehicle, the head-up display device comprising a mounting base, a projection component and a display assembly; the mounting base is arranged on the vehicle; the projection component and the display assembly are both connected to the mounting base, and the projection end of the projection component faces the display assembly.

[0043] The display assembly includes a display component, a coating component and a connecting component, wherein both ends of the connecting component are respectively connected to the display component and the mounting base; the display surface of the display component faces the driving seat of the vehicle; a coating component is provided on the side of the display component away from the driving seat of the vehicle, and the coating component is configured to cooperate with the display component to form an image.

[0044] For example, refer to Figure 1 As shown, when the driver is driving the vehicle, the projection unit 300 projects the vehicle's driving information to the display unit 101 through the projection end in real time, and the display unit 101 connected to the mounting base 700 displays the vehicle's driving information in real time, wherein the display surface of the display unit 101 is always within the driver's line of sight, and the actual position of the display unit 101 can be determined according to the position of the driver's eyes 600 and face. When the driver needs to view the vehicle information, the driver can view the vehicle's driving information in real time through the display surface of the display unit 101 set in front of him, and the driver no longer needs to lower his head to view the relevant vehicle driving information through the instrument panel, which avoids the driver's attention being distracted from observing the road ahead, and avoids the driver adjusting his eyes between observing the distant road and the nearby instrument panel, which can avoid eye fatigue and improve the driver's driving safety.

[0045] For example, by providing a coating member on the side of the display member 101 facing away from the driving seat of the vehicle, the coating member can serve as the background of the display member 101, thereby improving the clarity of the displayed information of the display member 101 and the effect of the display member 101 in displaying the driving information of the vehicle, which helps the driver to view the driving information.

[0046] For example, the material of the display element 101 can be glass, and the material of the coating element can be any one of metal, oxide, and nitride. The coating element can change the color, gloss, and texture of the glass, increase the decorative effect, and enhance the appearance of the head-up display device. In the process of preparing the display element 101, the coating element can be prepared on the side of the display element 101 away from the driver's seat by chemical plating, vacuum plating, thermal spraying, etc.

[0047] For example, when the coating member is black, the display member 101 has a black background. The black coating member can effectively block the strong light from outside the vehicle and improve the display effect of the display member 101. In this way, the display member 101 has the best clarity.

[0048] It is understandable that the coating member may also be gray or brown, which can also improve the clarity of information displayed by the display member 101 .

[0049] For example, the light projected by the projection element 300 is linearly polarized light, and the linearly polarized light includes p-polarized light and s-polarized light, wherein s represents vertically polarized light and p represents parallel polarized light. When the driver normally observes the light information projected by the projection element 300 onto the display element 101 through his eyes, the s-polarized light and the p-polarized light are reflected to the driver's eyes through the glass of the display element 101, and the driver's eyes can read the relevant vehicle driving information.

[0050] In some cases of scorching sun, when the driver needs to wear sunglasses, when the driver's glasses look at the display unit 101 through the sunglasses, the sunglasses will filter out the s-polarized light. Since the reflection of p-polarized light is lower than that of s-polarized light, this may cause the driver's eyes to be unable to clearly obtain the driving information of the vehicle on the display unit 101. Therefore, the glass used for the display unit 101 of the present application is treated with a P-light coating to prevent the driver from not being able to clearly see the display information of the display unit 101 due to wearing sunglasses.

[0051] As a feasible implementation, the head-up display device also includes a light blocking member, which is arranged on the front windshield of the vehicle. Along the direction of the display surface, the projection of the display member on the surface where the light blocking member is located at least partially overlaps with the light blocking member.

[0052] For example, by arranging the light blocking member 200 on the front windshield 400 of the vehicle, along the orientation direction of the display surface, the projection of the display member 101 on the surface where the light blocking member 200 is located at least partially overlaps with the light blocking member 200. During the driving of the vehicle, the light blocking member 200 blocks the display member 101. In this way, the personnel located in front of the vehicle cannot see the display member 101, thereby improving the neatness of the interior appearance of the vehicle and improving the aesthetics of the vehicle.

[0053] Second, refer to Figures 1 to 3As shown, an embodiment of the present application provides a head-up display device for projection inside a vehicle, the head-up display device includes a mounting base 700, a projection member 300, a display assembly 100 and a light blocking member 200; the mounting base 700 is arranged on the vehicle, and the light blocking member 200 is arranged on the front windshield 400 of the vehicle; the projection member 300 and the display assembly 100 are both connected to the mounting base 700, and the light blocking member 200 is connected to the display assembly 100; the projection end of the projection member 300 faces the display assembly 100.

[0054] The display assembly 100 includes a display component 101 and a connecting component 102, and the two ends of the connecting component 102 are respectively connected to the display component 101 and the mounting base 700; the display surface of the display component 101 faces the driving seat of the vehicle; along the direction of the display surface, the projection of the display component 101 on the surface where the light blocking component 200 is located at least partially overlaps with the light blocking component 200.

[0055] For example, refer to Figure 1 As shown, when the driver is driving the vehicle, the projection unit 300 projects the vehicle's driving information to the display unit 101 through the projection end in real time, and the display unit 101 connected to the mounting base 700 displays the vehicle's driving information in real time, wherein the display surface of the display unit 101 is always within the driver's line of sight, and the actual position of the display unit 101 can be determined according to the position of the driver's eyes 600 and face. When the driver needs to view the vehicle information, the driver can view the vehicle's driving information in real time through the display surface of the display unit 101 set in front of him, and the driver no longer needs to lower his head to view the relevant vehicle driving information through the instrument panel, which avoids the driver's attention being distracted from observing the road ahead, and avoids the driver adjusting his eyes between observing the distant road and the nearby instrument panel, which can avoid eye fatigue and improve the driver's driving safety.

[0056] In addition, by arranging the mounting base 700 and the projection component 300 in the vehicle body below the center console 500, installing the projection component 300 on the mounting base 700, and connecting the display component 101 to the mounting base 700 via the connecting component 102, it is beneficial to shorten the projection distance between the projection component 300 and the display component 101, and it is beneficial to reasonably utilize the limited space between the vehicle center console 500 and the windshield 400.

[0057] For example, by setting the light shielding member 200 on the front windshield 400 of the vehicle, along the direction of the display surface, the projection of the display member 101 on the surface where the light shielding member 200 is located overlaps with the light shielding member 200 at least partially, so that the light shielding member 200 can be used as the background of the display member 101, which improves the clarity of the display information of the display member 101, improves the effect of the display member 101 displaying the driving information of the vehicle, and helps the driver to view the driving information. At the same time, during the driving of the vehicle, the light shielding member 200 blocks the display member 101, so that the person in front of the vehicle cannot see the display member 101, which improves the neatness of the appearance of the interior of the vehicle and improves the aesthetics of the vehicle.

[0058] For example, the mounting base 700 and the projection element 300 are arranged below the display element 101. The mounting base 700 and the projection element 300 can be arranged in the vehicle body below the center console 500. By setting an opening in the center console 500 so that the projection end of the projection element 300 faces the display element 101, real-time projection is achieved.

[0059] For example, the mounting base 700 and the projection member 300 are arranged below the display member 101. The mounting base 700 and the projection member 300 can be accommodated in an interior element of the vehicle body or arranged submerged in the interior element. The interior element can have a recess, so that the mounting base 700 and the projection member 300 are at least partially arranged in the recess. Among them, the interior element can be a center console 500. The projection member 300 can project the driving information of the vehicle onto the display surface of the display member 101 facing the driver. The display information of the display surface is reflected, so that the driving information of the vehicle can be viewed from the display surface by the vehicle passengers, especially the driver.

[0060] As a feasible implementation mode, the head-up display device also includes a control component and a detection component, and the detection component and the projection component 300 are electrically connected to the control component; the detection component is configured to detect the driving information of the vehicle, and the control component controls the projection component 300 to project the driving information of the vehicle.

[0061] For example, the detection element can detect the driving information of the vehicle, and the driving information of the vehicle detected by the detection element includes the real-time speed of the vehicle, engine speed, fuel consumption information, vehicle mileage, and warning information during the driving process of the vehicle. The warning information includes warning information of not fastening the seat belt, fatigue driving information, and door not closed warning information.

[0062] For example, the detection element may be a wheel speed sensor on a wheel to detect the speed of the vehicle in real time. The present application does not limit the type of vehicle driving information.

[0063] For example, the control component can obtain information from the detection component in real time. For example, after the control component obtains the real-time speed of the vehicle through the wheel speed sensor, it controls the projection component 300 to project the real-time speed of the vehicle onto the display component 101, so that the driver can view the real-time speed of the vehicle through the display component 101 in front in real time, avoiding the driver from lowering his head to view the real-time speed of the vehicle through the dashboard when changing lanes, etc.

[0064] It is understandable that the vehicle's electronic control unit ECU (Electronic Control Unit) may also include a control component to realize the function of the control component.

[0065] As a feasible implementation, the display member 101 includes a housing and a display, the housing has an opening facing away from the connecting rod, the display is arranged in the housing, and the display surface of the display is exposed to the opening.

[0066] At least part of the housing is integral with the connecting rod.

[0067] In some embodiments, the display unit 101 includes a housing and a display, the opening of the housing faces the driving position, the display is arranged in the housing, and the display surface of the display faces the driving position. The housing and the connecting rod may be an integral part. The housing and the connecting rod may be made of transparent glass, and the housing and the connecting rod may be integrally formed by glass casting; the housing and the connecting rod may also be made of transparent plastic, and the housing and the connecting rod may be integrally formed by injection molding.

[0068] In other embodiments, the display component 101 includes a display panel, and the material of the display panel includes transparent glass and transparent plastic. When the material of the display panel and the connecting rod are both transparent glass, the display panel and the connecting rod can be integrally formed by a glass casting method; when the material of the display panel and the connecting rod are both transparent plastic, the display panel and the connecting rod can be integrally formed by injection molding.

[0069] As a feasible implementation manner, the connecting member 102 includes a detachably connected connecting base and a connecting rod, the connecting base is connected to the mounting base 700 , and the connecting rod is connected to the display member 101 .

[0070] In some embodiments, the connecting base can be a suction cup that can be adsorbed on the mounting base 700, and the suction cup has a plug-in portion. The connecting rod can be connected to the plug-in portion, so that the first end of the connecting rod is connected to the mounting base 700 through the suction cup, and the second end of the connecting rod is connected to the display unit 101, thereby realizing the connection between the display unit 101 and the windshield 400.

[0071] In other embodiments, when the connecting base is made of glass and the mounting base 700 is also made of glass, the mounting base 700 and the connecting base are welded together. During welding, a high-temperature airflow is sprayed out by a flame gun to preheat the mounting base 700 and the connecting base to the glass deformation temperature, and then the edge of the mounting base 700 and the edge of the connecting base are bonded to each other. In this way, a high-precision and high-quality connection effect of the mounting base 700 and the connecting base is achieved, and long-term stability and durability can be provided.

[0072] For example, the material of the mounting base 700 includes glass, plastic, and metal. The present application does not limit the material of the mounting base 700, as long as the connecting base and the mounting base 700 are tightly connected.

[0073] As a feasible implementation, the connecting rod includes a first connecting section, a second connecting section and a third connecting section which are connected in sequence, the extension direction of the first connecting section is the same as the extension direction of the mounting base 700, and is connected to the connecting base; the extension direction of the third connecting section is the same as the extension direction of the display surface, and is connected to the display element 101; the extension direction of the second connecting section intersects with the extension directions of the first connecting section and the third connecting section.

[0074] For example, after connecting the connecting base to the mounting base 700, the first connecting section is connected to the connecting base, and the extension direction of the first connecting section is set to be the same as the extension direction of the mounting base 700. This can increase the connection area between the first connecting section and the connecting base, thereby improving the connection strength of the connector 102.

[0075] For example, when the third connecting segment is connected to the display element 101, the extension direction of the third connecting segment is set to be the same as the extension direction of the display element 101, so that one side of the third connecting segment is connected to the display element 101, thereby increasing the connection area between the display element 101 and the connecting element 102, thereby improving the connection strength and connection stability.

[0076] For example, the extension direction of the second connecting segment intersects with the extension directions of the first connecting segment and the third connecting segment. The extension direction of the second connecting segment affects the display angle of the display unit 101. The display unit 101 with different display angles will affect the effect of the driver viewing the vehicle information through the display surface. Therefore, the present application does not limit the actual angle at which the extension direction of the second connecting segment intersects with the extension directions of the first connecting segment and the third connecting segment, in accordance with the principle of satisfying the best viewing effect for the driver.

[0077] As a feasible implementation, there are multiple display components 100 and multiple light blocking members 200, one display component 100 is correspondingly arranged with one light blocking member 200, and multiple light blocking members 200 are respectively arranged at different positions of the front windshield 400.

[0078] The projection element 300 includes a plurality of projection ends, and each projection end corresponds to one display assembly 100 .

[0079] For example, during the driving of the vehicle, the control component obtains the driving information of the vehicle from the detection component, and then the control component controls the projection component 300 to output an image. The output image is displayed on the display surface using the optical emission principle, and the driver can view the driving information of the vehicle through the display surface in real time.

[0080] Illustratively, the projecting member 300 includes a laser emitter.

[0081] For example, there may be two display components 100, one is arranged in front of the driver, and the other is arranged in front of the passenger in the front passenger seat. Correspondingly, a light blocking member 200 corresponding to the display component 100 is arranged on the front windshield 400, and different projection ends of the projection member 300 respectively project for the two display components 100. In this way, the vehicle information displayed on the display component 101 is reflected, and the driver and the front passenger read the driving information of the vehicle from the display surface.

[0082] As a feasible implementation manner, the light blocking surface of the light blocking member 200 extends along the first direction of the front windshield 400; the display surface of the display member 101 and the light blocking surface are parallel to each other.

[0083] For example, refer to Figure 1 As shown, the driver can view the information outside the vehicle through the windshield 400, including the driving status of the vehicle ahead, the status of pedestrians on the roadside, the actual road surface information, and the traffic signs and auxiliary signs set on the road. By setting the light shielding member 200 at the end of the windshield 400 close to the wiper, the position of the light shielding member 200 does not affect the driver's viewing of the information outside the vehicle through the windshield 400, and the light shielding member 200 can block the windshield 400 near the wiper. When the display surface of the display member 101 and the light shielding surface are parallel to each other, the light shielding member 200 can serve as the background of the display member 101. From the driver's perspective, the driver can view the driving information of the vehicle through the display member 101 without being disturbed by the external information of the vehicle, which is conducive to the driver viewing the driving information of the vehicle through the display member 101.

[0084] For example, the first direction of the windshield 400 is the left and right direction of the driver, and the light blocking surface of the light blocking member 200 may extend along the first direction to provide a background for the display member 101 .

[0085] As a feasible implementation, along the first direction of the front windshield 400 , the extension length of the light blocking surface of the light blocking member 200 is greater than the extension length of the display surface of the display member 101 .

[0086] For example, when the extension length of the light blocking surface of the light blocking member 200 is greater than the extension length of the display surface of the display member 101, the projection of the display member 101 on the surface where the light blocking member 200 is located completely falls into the light blocking surface of the light blocking member 200. Figure 1 As shown by the dotted line between the display element 101 and the light blocking element 200, part of the light blocking element 200 can completely serve as the background of the display element 101. In this way, when the projection element 300 projects part of the vehicle's driving information onto the edge of the display element 101, the vehicle's driving information can still be clearly seen from the driver's perspective, thereby making full use of the display area of ​​the display element 101.

[0087] In addition, when the projection of the display element 101 on the surface where the light blocking element 200 is located completely falls into the light blocking element 200, from the driver's perspective, the driver can view relevant vehicle information through the display element 101 without being disturbed by external information of the vehicle, thereby improving the efficiency of the driver in viewing the vehicle's driving information.

[0088] As a feasible implementation manner, the light blocking member 200 is a film silk-screened member; and / or the color of the light blocking member 200 includes any one of black, dark gray and coal gray.

[0089] As an achievable implementation manner, the color of the display element 101 includes black.

[0090] For example, the light shielding member 200 can have any shape, for example, the light shielding member 200 can be any one of square, circular, trapezoidal, and elliptical. The shape of the light shielding member 200 satisfies the requirements that the projection of the display member 101 on the surface where the light shielding member 200 is located at least partially overlaps with the light shielding member 200, does not obstruct the driver's line of sight, and meets the requirements of aesthetics. Therefore, the present application does not limit the specific shape of the light shielding member 200.

[0091] For example, the light blocking member 200 can be a film screen printing member, for example, the film screen printing member can be a film with color. The film is laminated on the windshield 400, and the laminated film has the advantage of low cost in the windshield 400. In addition, the windshield 400 does not include expensive electronic components, so it can be replaced at low cost. Therefore, this film with color can be flexibly applied to the desired position of the windshield 400.

[0092] In some embodiments, when the projection element 300 projects the vehicle's driving information onto the display element 101, the light on the display surface is reflected into the driver's eyes, and the driver can view the vehicle's driving information on the display surface in real time. When the light blocking element 200 is black, the light blocking element 200 can provide a black background for the display element 101, thereby improving the contrast of the display information on the display surface, thereby improving the clarity of the vehicle's driving information on the display element 101.

[0093] In other embodiments, the color of the light blocking member 200 may also be coal gray. The coal gray light blocking member 200 can also provide a gray background for the display member 101, thereby improving the clarity of the vehicle driving information on the display member 101. In addition, when the light blocking member 200 is coal gray, it can also be matched with a vehicle body of a corresponding color to achieve the purpose of aesthetics.

[0094] In some other embodiments, the color of the light shielding member 200 near the wiper is black, and the color of the light shielding member 200 away from the wiper is gray. In this way, the light shielding member 200 can be divided into an upper gray area and a lower black area. Correspondingly, the display member 101 can be divided into a first display portion corresponding to the gray area and a second display portion corresponding to the black area. The first display portion can be used to display driving information such as the real-time speed of the vehicle and the vehicle's cruising range. The second display portion can be used to display the content of the alarm information in the vehicle's driving information, such as the alarm indication information of the door not being closed. By setting the light shielding member 200 in different color areas, it is convenient for the driver to view the driving information of the vehicle as needed.

[0095] For example, the display element 101 may be made of black glass, which further enhances the display effect of the display element 101 against the background of the light blocking element 200 .

[0096] In a third aspect, the present application provides a vehicle including a cockpit, a windshield 400 and a head-up display device, wherein the windshield 400 is arranged in the cockpit and is opposite to the driving position of the cockpit, and the head-up display device is arranged in the cockpit, and at least part of the head-up display device is connected to the cockpit.

[0097] The display surface of the head-up display device faces the driving seat of the vehicle.

[0098] For example, by setting the head-up display device in the cockpit of the vehicle, the head-up display device can directly superimpose the vehicle information on the real road scene seen by the driver, so that the driver does not need to look down at the instrument panel set on the center console 500 during driving, thereby improving driving safety. The vehicle equipped with the head-up display device realizes superimposing the projected virtual image of the vehicle's driving information with real objects, realizing the deep integration of driving information and the real world.
