Description

Technical Field

[0001] This application relates to the field of automotive technology, and more particularly to an in-vehicle projection system and a vehicle. Background Technology

[0002] With the increasing popularity of passenger cars, people have higher and higher requirements for the comfort and entertainment of passenger vehicles, and in-vehicle projection systems are gradually attracting attention. An in-vehicle projection system is a multi-functional entertainment system that provides a large-screen audio-visual experience inside the car, satisfying users' desire for a superior in-vehicle audio-visual entertainment experience. In-vehicle projection systems require a certain amount of projection space. In the limited space inside a car, it is essential to choose a suitable projection space for the in-vehicle projection system to meet the user's needs for a large-screen audio-visual experience.

[0003] In related technologies, the projection space of an in-vehicle projection system is typically determined by the installation location of the projection module, which is usually installed on the ceiling inside the vehicle. However, the projection direction at this installation location is generally such that the projection module projects along the vehicle's direction of travel towards the windshield, thus obstructing the driver's view and affecting normal driving. Consequently, the user cannot use the in-vehicle projection system while the vehicle is in motion. For example, some vehicles install the projection module in the ceiling with the screen at the front. When in use, the screen is pulled down, obstructing the driver's view and affecting normal driving, making the in-vehicle projection system unusable while the vehicle is in motion.

[0004] It should be noted that the information disclosed in the background section of this application is intended only to enhance the understanding of the general background of this application, and should not be regarded as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0006] In a first aspect, embodiments of this application provide an in-vehicle projection system, the system comprising: A projection module is installed at the bottom of the vehicle interior to project onto the top of the vehicle interior.

[0007] In this embodiment, the projection module of the vehicle projection system projects from the bottom of the vehicle to the top of the vehicle, which ensures that the vehicle projection system will not obstruct the driver's view or affect normal driving, thereby avoiding the problem of not being able to use the vehicle projection system while the vehicle is in motion.

[0008] In one possible implementation, the vehicle-mounted projection system includes: The projection range of the projection module is located within the sunroof sunshade of the vehicle.

[0009] In this embodiment, the screen of the vehicle projection system can reuse the sunroof sunshade of the vehicle, eliminating the need to carry or install additional screen components, thus improving the convenience of using the vehicle projection system.

[0013] In this embodiment of the application, a separate screen can also be installed for the vehicle projection system to make the projection effect clearer and further improve the user's audio-visual experience.

[0014] In one possible implementation, the vehicle projection system includes: The projection module is embedded in the bottom of the vehicle.

[0015] In this embodiment, the projection module is embedded in the bottom of the vehicle, which will not affect the user's riding experience or be damaged by the user kicking it. While not affecting the user's riding experience, it also improves the safety of the vehicle projection system itself.

[0016] In one possible implementation, the vehicle projection system includes: The projection module is used to be positioned within the projection area of ​​the sunroof at the bottom of the vehicle interior.

[0017] In this embodiment, the projection module is installed in the projection area of ​​the sunroof at the bottom of the vehicle interior, which makes the projection angle easy to adjust, the projection light path unobstructed, and the projection image clearer, further improving the user's audio-visual experience.

[0018] In one possible implementation, the vehicle projection system further includes: The control terminal is used to control the projection module to project.

[0019] In this embodiment, the control terminal of the vehicle projection system can control the projection module to turn on or off, the projection angle, the light source brightness and other projection states, which further improves the ease of use of the vehicle projection system.

[0020] In one possible implementation, the vehicle projection system includes: The control terminal is a terminal device.

[0021] In this embodiment, the vehicle projection system can be controlled by a terminal device outside the vehicle, which improves the ease of use of the vehicle projection system.

[0022] In one possible implementation, the vehicle projection system includes: The control terminal is the vehicle's central control unit.

[0023] In this embodiment, the vehicle projection system can be controlled by the vehicle's central control unit, which improves the ease of use of the vehicle projection system.

[0037] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0038] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0039] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0040] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0041] To facilitate understanding, the concepts involved in the embodiments of this application will be briefly described below.

[0042] Projection space refers to the necessary space required for the use of a vehicle-mounted projection system, including the projection module, screen, and projection optical path range.

[0043] In-vehicle projection systems typically occupy necessary projection space, which may overlap with the driver's field of vision, potentially obstructing the driver's view. The driver's field of vision refers to the area within the driver's view of the road conditions observed through the windshield, side mirrors, etc. Therefore, within the limited space of the vehicle interior, proper planning of the projection space can prevent this overlap with the driver's field of vision.

[0044] To facilitate understanding, specific application scenarios will be illustrated below.

[0045] See Figure 1 This provides a schematic diagram of an application scenario for an embodiment of this application. For example... Figure 1 As shown, the vehicle 101 includes a projection module 102. Specifically, the projection module 102 is installed inside the vehicle 101.

[0046] Vehicle 101 is a passenger car, primarily used for carrying passengers and their personal luggage or temporary belongings, and needs to meet the passengers' entertainment and comfort needs. Passenger cars encompass sedans, minibuses, and light passenger vehicles with no more than 9 seats. Vehicle 101 can be a regular passenger car, a convertible passenger car, a luxury passenger car, a small passenger car, a hatchback passenger car, or a station wagon, etc.

[0047] Projection module 102 is a projector device that can project images or video signals onto a flat surface by connecting to a computer, high-density digital video disc (DVD), video compact disc (VCD), game console, digital video (DV), etc. Projection module 102 can be a vehicle head-up display projector, in-vehicle holographic projector, digital light processing projector, off-axis optical projector, laser scanning projector, thin-film transistor projector, etc.

[0048] in addition, Figure 1 The vehicle structure shown is merely an exemplary description and should not be construed as a limitation on the scope of protection of this application.

[0049] In related technologies, the projection space of an in-vehicle projection system is typically determined by the installation location of the projection module 102, which is usually installed on the ceiling of the vehicle. However, the projection direction at this installation location is generally such that the projection module 102 projects onto the windshield of the vehicle 101 along the direction of travel of the vehicle 101, thereby obstructing the driver's view and affecting normal driving. Consequently, the user cannot use the in-vehicle projection system while the vehicle 101 is in motion. For example, some vehicles install the projection module on the ceiling and the screen at the front of the ceiling. When in use, the screen is pulled down, obstructing the driver's view and affecting normal driving, making it impossible to use the in-vehicle projection system while the vehicle is in motion.

[0050] To address the aforementioned issues, in this embodiment of the application, a projection module 102 of an in-vehicle projection system is installed at the bottom of the vehicle interior, projecting towards the top of the vehicle interior. Since the projection space does not intersect with the driver's field of vision along the driving direction of the vehicle 101, the projection space should not obstruct the driver's view, thus ensuring that normal driving is not hindered when using the in-vehicle projection system.

[0051] Specifically, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments.

[0052] See Figure 2 This embodiment of the application illustrates the projection direction of a projection module 102 within a vehicle. The installation position and projection direction of the projection module 102 can be applied to... Figure 1 In the scenario shown. For example... Figure 2 As shown, the projection module 102 is located at the bottom of the vehicle interior, with the projection direction facing the top of the vehicle interior.

[0053] It should be pointed out that, Figure 2 The schematic diagram of the projection direction of the projection module 102 inside the vehicle is merely an illustrative example of the projection module 102 projecting from the bottom of the vehicle interior towards the top. In practical applications, those skilled in the art can determine the actual projection direction of the projection module 102 based on its specific projection angle.

[0054] The arrangement of seats in a vehicle will occupy the space under the vehicle, and the installation location of the projection module 102 requires that there be no obstructions between the bottom and top of the vehicle. Therefore, the area under the vehicle that can be used to install the projection module 102 needs to be determined based on the distribution of seats in the vehicle.

[0055] See Figure 3 This is a schematic diagram of a possible installation area for a projection module 102 at the bottom of a vehicle, provided in an embodiment of this application. This installation area can be applied to... Figure 1 In the application scenario shown, vehicle 101 may have two rows of seats, such as... Figure 3As shown, along the driving direction of vehicle 101, the seats are arranged in the first row and the second row. There are no obstructions between the floor and ceiling of the vehicle interior in the area between the first and second rows of seats. The projection module 102 may be installed in the floor area between the first and second rows of seats.

[0056] It should be pointed out that, Figure 3 The schematic diagram of the possible installation area of ​​the projection module 102 at the bottom of the vehicle is only an exemplary illustration of the possible installation area of ​​the projection module 102 at the bottom of the vehicle. In practical applications, those skilled in the art can determine the specific installation area of ​​the projection module 102 at the bottom of the vehicle based on the actual seat distribution and other obstruction distribution inside the vehicle.

[0057] Some vehicles may have three rows of seats. See also Figure 4 This is a schematic diagram of the installation area for a projection module at the bottom of a vehicle interior with three rows of seats, provided in an embodiment of this application. This installation area can be applied to... Figure 1 In the scenario shown. For example... Figure 4 As shown, vehicle 101 may have three rows of seats, arranged sequentially along the direction of travel: first row, second row, and third row. In the area between any two adjacent rows of seats, there are no obstructions between the floor and ceiling of the vehicle interior. Figure 4 The first projection module installation area and the second projection module installation area are shown. The projection module 102 may be installed only in the first projection module installation area or the second projection module installation area, or it may be installed in both areas.

[0058] It should be pointed out that, Figure 4 The schematic diagram shown is of a projection module installation area at the bottom of a three-row seat interior, and is merely an exemplary illustration of the installation area of ​​the projection module 102 at the bottom of the three-row seat interior. In practical applications, those skilled in the art can determine the specific installation area of ​​the projection module 102 at the bottom of the vehicle interior based on the actual seat distribution inside the vehicle.

[0059] Similarly, some vehicles may have more than three rows of seats, and the installation area of ​​the projection module 102 may be located in any one of the under-cabin areas between any two adjacent rows of seats, where there are no obstructions from the under-cabin to the ceiling. Alternatively, the projection module 102 may be installed in each of the under-cabin areas between any two adjacent rows of seats, where there are no obstructions from the under-cabin to the ceiling.

[0060] As described above, the installation area of ​​the projection module 102 at the bottom of the vehicle interior can be determined. Since the projection direction of the projection module 102 is from the bottom of the vehicle interior to the top, the projection area of ​​the projection module 102 at the top of the vehicle interior also needs to be planned reasonably. In this embodiment, the projection module 102 projects from the bottom of the vehicle interior towards the top, and the projection range of the projection module 102 is located within the sunroof sunshade of the vehicle 101.

[0061] See Figure 5 This is a schematic diagram of the projection range of a projection module 102 provided in an embodiment of this application. Figure 5 As shown in this embodiment, the projection range of the projection module 102 on the roof of the vehicle is located within the sunroof sunshade area of ​​the vehicle 101. The vehicle projection system can reuse the sunroof sunshade of the vehicle 101 as a screen, eliminating the need to carry or install additional screen components, thereby improving the ease of use of the vehicle projection system.

[0062] It should be pointed out that, Figure 5 The schematic diagram of the projection range of the projection module 102 shown is only an exemplary illustration of the projection range of the projection module 102 inside the vehicle. In practical applications, those skilled in the art can determine the specific projection range of the projection module 102 on the top of the vehicle interior based on the location of the sunroof sunshade of a specific vehicle.

[0063] In this embodiment, the sunroof sunshade can be opened or closed when used as a screen. When used as a screen for an in-vehicle projection system, the sunroof sunshade can be opened normally and features low light transmission, a smooth surface, and concentrated brightness. The vehicle's sunroof sunshade can be a silver-coated curtain, a natural-colored curtain, a suede curtain, etc. The sunroof sunshade can be opened or closed via the vehicle's central control unit switch, car key operation, remote control operation, manual pulling, etc.

[0064] Since some vehicles lack sunroofs and therefore sunroof shades, or some users desire a clearer audio-visual experience with a screen, this embodiment proposes installing a screen inside the vehicle for the in-vehicle projection system. The screen is positioned on the ceiling of the vehicle interior, and the projection area of ​​the projection module 102 is located within the screen. Therefore, the installation area of ​​the screen on the ceiling of the vehicle interior is determined by the installation area of ​​the projection module 102.

[0065] See Figure 6 This is a schematic diagram of an installation area for a screen on the ceiling of a vehicle, provided in an embodiment of this application. This installation area can be applied to... Figure 1 In the application scenario shown, vehicle 101 may have two rows of seats, such as Figure 6As shown, along the driving direction of vehicle 101, there are, in order, the first row of seats and the second row of seats. Based on the possible installation area of ​​the projection module 102 described above, the possible installation area of ​​the screen is located in the interior ceiling area between the first and second row seats, where there are no obstructions from the interior ceiling to the interior floor. The screen is used parallel to the interior ceiling, and when in use, it completely encompasses the projection range of the projection module 102.

[0066] It should be pointed out that, Figure 6 The schematic diagram shown is only an illustrative example of the installation area of ​​the screen on the ceiling of the vehicle. In practical applications, those skilled in the art can determine the specific installation area of ​​the screen on the ceiling of the vehicle based on the installation position of the projection module 102 in the specific vehicle.

[0067] Some vehicles may have three rows of seats, see Figure 7 This is a schematic diagram of an installation area for a roof curtain in a three-row vehicle interior, as provided in an embodiment of this application. This installation area can be applied to... Figure 1 In the application scenario shown, vehicle 101 may have three rows of seats, arranged sequentially along the direction of travel: first row, second row, and third row. There are no obstructions between any two adjacent rows of seats, from the top to the bottom of the interior. Figure 7 The diagram shows the first and second curtain installation areas. The curtain may be installed only in the first or second curtain installation area, or it may be installed in both areas.

[0068] It should be pointed out that, Figure 7 The schematic diagram shown is merely an illustrative example of a screen installation area on the ceiling of a vehicle with three rows of seats. In practical applications, those skilled in the art can determine the specific installation area of ​​the screen on the ceiling of the vehicle based on the specific installation location of the projection module 102.

[0069] Similarly, some vehicles may have more than three rows of seats, and the curtain may be installed in any one of the interior ceiling areas between any two adjacent rows of seats, where there are no obstructions from the top to the bottom of the vehicle interior. Alternatively, the curtain may be installed in each of the interior ceiling areas between any two adjacent rows of seats, where there are no obstructions from the top to the bottom of the vehicle interior.

[0070] See Figure 8 This is a schematic diagram illustrating the relative positions of the screen area and the projection module 102 within a vehicle, as provided in an embodiment of this application. Figure 8As shown in this embodiment, the screen of the vehicle projection system can completely encompass the projection range of the projection module 102, so that the image projected by the projection module 102 can be fully displayed on the screen.

[0071] It should be pointed out that, Figure 8 The schematic diagram showing the relative positions of the screen area and the projection module 102 inside the vehicle is merely an illustrative example of their relative positions. In practical applications, those skilled in the art can determine the specific installation position of the screen on the ceiling of the vehicle based on the installation location of the projection module 102 in a particular vehicle.

[0072] As described above, the installation area for the projection module 102 has been determined; therefore, the installation method for the projection module 102 also needs to be planned appropriately. In this embodiment, the projection module 102 is embedded in the bottom of the vehicle interior. The projection module 102 includes a projection lens and a mounting compartment. The projection lens is located inside the mounting compartment, and an installation mechanism is located outside the mounting compartment, allowing the projection module 102 to be embedded and installed in the bottom of the vehicle interior. This embedded installation method allows the projection module 102 to be hidden in the bottom of the vehicle interior, preventing obstruction of users getting in and out of the vehicle and preventing damage to the projection equipment by the user.

[0073] In this embodiment, the projection module 102 is configured to be positioned within the projection area of ​​the sunroof at the bottom of the vehicle interior. The projection area of ​​the sunroof at the bottom of the vehicle interior can be either an orthographic projection area or an oblique projection area.

[0074] See Figure 9 This is a schematic diagram of the projection area of ​​a projection module 102 in the sunroof at the bottom of the vehicle interior, provided in an embodiment of this application. Figure 9 As shown, the installation area of ​​the projection module 102 is the projection area of ​​the sunroof at the bottom of the vehicle interior.

[0075] It should be pointed out that, Figure 9 The schematic diagram of the projection module 102 in the projection area of ​​the sunroof at the bottom of the vehicle interior is merely an illustrative example. In practical applications, those skilled in the art can determine the installation area of ​​the projection module 102 at the bottom of the vehicle interior based on the specific location of the sunroof.

[0076] In this embodiment, the vehicle-mounted projection system also includes a control terminal. The control terminal is used to control the projection module 102. As described above, the projection module 102 includes a projection lens and a mounting compartment. See also... Figure 10 This is a schematic diagram of the projection lens structure provided in an embodiment of this application. Figure 10As shown, the projection lens includes an imaging engine, a signal and control module, an optical path module, and a heat dissipation module. The signal and control module is connected to the control terminal and is used to control the projection lens to turn on or off. The optical path module is connected to the control terminal and is used to control the brightness and angle of the light source in the projection optical path. The imaging engine is used to optimize image signal processing and ensure high-quality image signal output. The heat dissipation module is connected to the control terminal and is used to adjust the temperature of the projection lens to prevent it from overheating.

[0077] It should be pointed out that, Figure 10 The schematic diagram of the projection lens structure shown is merely an illustrative example. In practical applications, those skilled in the art can determine the actual structure of the projection lens based on the specific projection lens being used.

[0078] The control unit comprises two parts: a terminal device and the vehicle's central control unit. The terminal device can be a mobile terminal external to the vehicle, such as a smartphone, tablet, smartwatch, smart home device, AR (Augmented Reality) device, or VR (Virtual Reality) device, or a personal computer (PC), such as a laptop or desktop computer. The terminal device typically communicates with the vehicle's central control unit via the Internet, thereby controlling the projection module 102 to perform projection.

[0079] See Figure 11 This is a schematic diagram of the control relationship of an in-vehicle projection system provided in an embodiment of this application. Figure 11 As shown, the terminal device mentioned above can be a mobile phone. The mobile phone communicates with the vehicle's central control unit via the Internet, and controls the projection module to turn on or off through the mobile phone projection function of the central control unit, thereby controlling the projection lens to turn on or off. When the projection lens is on, the image is projected onto a screen on the ceiling of the vehicle. Similarly, the projection module can also be controlled directly through the projection switch function of the vehicle's central control unit.

[0080] It should be pointed out that, Figure 11 The schematic diagram illustrating the control relationship of an in-vehicle projection system is merely an exemplary illustration. In practical applications, those skilled in the art can determine the control relationship of an in-vehicle projection system based on its specific features.
