Description

Technical Field

[0001] This application relates to projection display technology. More specifically, it relates to an in-vehicle projection system and a vehicle. Background Technology

[0002] In existing cars, in addition to passenger entertainment devices such as portable mobile phones and tablets, there are also built-in multimedia devices. However, portable devices cannot free up the hands, and their screens are relatively small; although built-in multimedia devices can free up the hands, their screen size is also relatively limited, making interactive entertainment, office work, and operation less convenient.

[0003] In related technologies, some cars are equipped with in-vehicle projection devices that have a large screen size and allow for hands-free operation. These in-vehicle projection devices are fixed to the car's interior with screws.

[0004] However, the installation method of the aforementioned in-vehicle projection equipment can cause damage to the vehicle's interior. Utility Model Content

[0005] This application provides an in-vehicle projection system and a vehicle, which can solve the technical problem in the related art where in-vehicle projection equipment is installed inside the car with screws, causing damage to the car interior.

[0006] In a first aspect, embodiments of this application provide an in-vehicle projection system, installed inside a vehicle, the in-vehicle projection system comprising:

[0007] A projection device is used to be installed at the rear of the vehicle to project images.

[0008] A projection screen is used to display the image projected by the projection device;

[0009] An installation device is connected to the projection screen, and the installation device can be detachably installed inside the vehicle.

[0010] This application provides an in-vehicle projection system that is not fixed inside the vehicle with screws, thus avoiding physical damage to the vehicle's interior and protecting the aesthetics and integrity of the interior.

[0011] By placing the projection equipment at the rear of the vehicle, interior space can be effectively utilized, avoiding interference with the driver's view. This layout provides a larger projection distance, resulting in a larger projected image and improving the viewing experience for rear passengers.

[0012] By incorporating a mounting device that connects to the projection screen and can be detachably attached to the vehicle, the installation and removal of the projection screen becomes convenient, improving user ease of operation. Furthermore, users can adjust or change the position or angle of the projection screen as needed to obtain the best viewing experience, while also facilitating the maintenance and replacement of the projection equipment's screen.

[0013] In addition, thanks to the above configuration, the detachable projection screen can be adapted to different car models, making it highly versatile.

[0014] As an optional implementation, the mounting device is used to mount the projection screen to the sunroof of a vehicle;

[0015] The installation device includes:

[0016] A first magnetic component is located at the top of the projection screen and is connected to the projection screen;

[0017] The second magnetic component is detachably installed in the vehicle sunroof;

[0018] The first magnetic component and the second magnetic component are magnetically connected.

[0019] With the above setup, the first and second magnetic components provide a stable connection, allowing the projection screen to be securely fixed to the sunroof while enabling quick installation and removal. The second magnetic component can be installed seamlessly with the first, avoiding damage to the vehicle's interior. The magnetic connection also allows users to quickly adjust or remove the projection screen as needed.

[0020] As an optional implementation, the first magnetic component and the second magnetic component are arranged at intervals, and the second magnetic component is used to attract the sunroof of the vehicle.

[0021] When the vehicle sunshade covers the sunroof, the first magnetic component and the second magnetic component are located on opposite sides of the vehicle sunshade, and the first magnetic component is installed on the vehicle sunroof through the second magnetic component.

[0022] When the vehicle sunshade covers the sunroof, the first and second magnetic components are located on opposite sides of the sunshade. This ensures the sunshade functions properly, effectively blocking external light from interfering with the projection effect and providing a clearer projected image. Simultaneously, this setup enhances the flexibility and compatibility of the in-vehicle projection system, making it suitable for various vehicle models.

[0023] In some embodiments of this application, the first magnetic component has a first magnetic surface, the second magnetic component has a second magnetic surface, and the area of ​​the first magnetic surface is less than or equal to the area of ​​the second magnetic surface.

[0024] With the above configuration, the larger second magnetic surface provides greater tolerance, ensuring a good connection even when the first magnetic component is misaligned during installation, thus improving the reliability and stability of the connection and reducing the risk of loosening or detachment due to improper installation. On the other hand, it allows users to easily adjust the relative positions of the first and second magnetic components according to their viewing experience, thereby changing the position of the projection screen relative to the skylight. This convenient adjustment method enhances the user experience.

[0025] In some embodiments of this application, the first magnetic component includes:

[0026] The outer casing is connected to the projection screen;

[0027] The first magnetic part is connected to the side of the outer casing away from the projection screen;

[0028] The second magnetic component includes:

[0029] The suction cup portion, one end of which is used to adhere to the vehicle sunroof;

[0030] The second magnetic part is connected to the other end of the suction cup part;

[0031] The magnetism of the first magnetic part and the second magnetic part are magnetically attracted to each other.

[0032] By ensuring that the first and second magnetic parts are magnetically attracted to each other, the vehicle-mounted projection system can achieve a strong magnetic attraction, thus providing a stable connection. Furthermore, users can easily align and connect the housing and suction cup using simple magnetic attraction, simplifying the installation process of the vehicle-mounted projection system.

[0033] In some embodiments of this application, the first magnetic component further includes a connecting portion, the connecting portion being connected between the housing and the first magnetic component;

[0034] The length of the connecting part is adjustable to change the distance between the outer shell and the first magnetic part.

[0035] By adjusting the distance between the outer casing and the first magnetic component, users can change the position and angle of the projection screen to achieve a better projection effect. This adjustability allows the in-vehicle projection system to adapt to different vehicle interior layouts and user preferences, providing a better user experience. Furthermore, these features may also help reduce the impact of vibration or shock on the projection screen, improving the durability and stability of the in-vehicle projection system.

[0036] In some embodiments of this application, the outer shell has a receiving cavity and a through hole communicating with the receiving cavity;

[0037] The connecting portion includes a bolt and a limiting member located within the receiving cavity. The limiting member is disposed around the through hole, and the limiting member and the outer shell together form a limiting space; wherein, the bolt includes:

[0038] The head is located within the restricted space;

[0039] The first stud has one end connected to the head and the other end passing through the through hole.

[0040] The first magnetic part has a first threaded hole corresponding to the first stud, and the outer casing is threadedly connected to the first threaded hole of the first magnetic part by the first stud of the bolt.

[0041] With the above settings, a stable connection can be formed between the outer shell and the first magnetic part through the limiting parts and bolts. The threaded connection method can improve the installation stability and usage effect of the projection screen, thereby enhancing the durability and adaptability of the vehicle projection system and ensuring good performance under different usage conditions. On the other hand, it can change the distance between the outer shell and the first magnetic part, allowing users to freely change the position and angle of the projection screen to obtain a better projection effect.

[0042] In some embodiments of this application, the first magnetic component further includes a self-locking part, which is connected between the outer shell and the first magnetic part, and the self-locking part is spaced apart from the connecting part;

[0043] The self-locking part is configured to lock the outer shell and the first magnetic part when the distance between the outer shell and the first magnetic part is at its maximum.

[0044] The self-locking mechanism ensures that the movement distance between the outer casing and the first magnetic part does not exceed the maximum distance, preventing unstable connection or detachment due to over-adjustment, thus improving the durability of the vehicle projection system and user safety. The self-locking mechanism and the connecting part are spaced apart, allowing them to operate independently and avoiding conflict. This allows the connecting part to freely adjust the distance between the outer casing and the first magnetic part, while the self-locking mechanism ensures that the movement between the outer casing and the second magnetic part is completed within a preset distance.

[0045] In some embodiments of this application, the self-locking part includes a spring, the spring being sleeved on the first stud, and the opposite ends of the spring respectively abutting against the outer shell and the first magnetic part.

[0046] By fitting a spring onto the first stud, mutual interference between the stud and the spring can be avoided, simplifying the structure of the connecting part and the self-locking part. The spring can apply elastic force along the axis of the stud, thereby enhancing the locking effect. When the distance between the housing and the first magnetic part changes, the spring can automatically adjust its length, thus achieving automatic locking or unlocking. By incorporating the spring, it is ensured that the connection between the housing and the first magnetic part remains stable under different operating conditions, achieving a self-locking effect.

[0047] In some embodiments of this application, the number of the second magnetic components is multiple, and the first magnetic component includes multiple second magnetic parts, which are spaced apart on the housing.

[0048] Each of the first magnetic parts corresponds one-to-one with the second magnetic part of the second magnetic assembly.

[0049] By securing the system in multiple locations, the vehicle-mounted projection system can better distribute the load, reducing the pressure on individual suction cups and thus improving overall stability and durability. The spaced arrangement helps to evenly distribute the load and stress, preventing stress concentration that could lead to damage. This arrangement enhances the stability and durability of the vehicle-mounted projection system while also allowing for flexible installation to suit different vehicles and user needs.

[0050] In some embodiments of this application, the suction cup portion includes:

[0051] The suction cup body is used to attach to the sunroof of a vehicle;

[0052] The second stud is connected to the outside of the suction cup body and is fixedly connected to the suction cup body;

[0053] The second magnetic part has a second threaded hole corresponding to the second stud, and the suction cup body is threadedly connected to the second threaded hole of the second magnetic part through the second stud.

[0054] The suction cup body and the second magnetic part can be connected securely by the second stud. The threaded connection can improve the installation stability and performance of the projection screen, thereby enhancing the durability and adaptability of the vehicle projection system and ensuring good performance under different usage conditions. On the other hand, the second magnetic part and the suction cup body can be disassembled to replace the suction cup body according to the usage.

[0055] Secondly, this application also provides a vehicle, including a vehicle body, a sunroof, a sunshade, and the aforementioned vehicle projection system, wherein the sunshade is located inside the sunroof, and the sunroof, the sunshade, and the vehicle projection system are all connected to the vehicle body.

[0056] The above settings allow the sunshade to move freely even when the projection screen is installed, effectively blocking external light and improving the clarity of the projection effect. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0088] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0089] Reference Figure 1 In a first aspect, embodiments of this application provide a vehicle 10. Specifically, the vehicle 10 includes a vehicle body 11, a sunroof 12, and a sunshade 13.

[0090] The sunroof 12 is typically located on the roof and is used to increase interior lighting and ventilation. The sunshade 13 is used to block sunlight and protect passenger privacy. The sunshade 13 is located inside the sunroof 12, and the sunroof 12, sunshade 13, and in-vehicle projection system 20 are all connected to the vehicle body 11. The sunshade 13 is installed inside the sunroof 12 and is connected to the vehicle body 11 along with the sunroof 12 and the in-vehicle projection system 20.

[0091] The design of the sunshade 13 being located inside the skylight 12 allows the sunshade 13 to be operated without affecting the function of the skylight 12. The above connection method ensures the stability and integrity of the sunshade 13 and the skylight 12.

[0092] Secondly, embodiments of this application provide an in-vehicle projection system 20, which is installed inside a vehicle 10. The in-vehicle projection system 20 includes a projection device 100, a projection screen 200, and a mounting device 30.

[0093] Projection device 100 is used to project images, and projection screen 200 is located on the light-emitting side of projection device 100 to display the projected images. Projection screen 200 provides a dedicated display area capable of presenting clear images and videos, which can enhance the passenger's viewing experience.

[0094] Installing a projection system inside the vehicle can make full use of the interior space, providing passengers with a better entertainment experience, without affecting the vehicle's appearance and aerodynamic performance.

[0095] Understandably, the projection device 100 can choose its installation location based on the actual situation. (Refer to...) Figure 2 For example, when the projection screen 200 is installed at the sunroof 12, the sunroof 12 is typically located in the middle of the vehicle 10. Therefore, the projection device 100 can be installed at the rear or front of the vehicle 10. This application embodiment does not limit the specific location of the projection device 100, nor is it limited to the above example. The following description uses the example of the projection device 100 being installed at the rear of the vehicle 10, i.e., on the rear seat.

[0096] Reference Figure 3 By placing the projection device 100 at the rear, the vehicle's interior space can be utilized to provide a longer projection distance, thereby achieving a larger projection screen; it can also avoid interfering with the driver's line of sight and improve safety.

[0097] By placing the projection equipment at the rear of the vehicle, interior space can be effectively utilized, avoiding interference with the driver's view. This layout provides a larger projection distance, resulting in a larger projected image and improving the viewing experience for rear passengers.

[0098] The mounting device 30 is connected to the projection screen 200 and can be detachably installed inside the vehicle 10, that is, inside the vehicle body 11.

[0099] Understandably, detachable features do not include the option of fixing the interior to the vehicle without screws, thus avoiding physical damage to the interior and protecting its aesthetics and integrity.

[0100] By providing an installation device 30 that connects to the projection screen 200 and is detachably attached to the vehicle, the installation and removal of the projection screen 200 becomes more convenient, improving user ease of operation. Furthermore, users can adjust or change the position or angle of the projection screen 200 as needed to obtain the best viewing experience, while also facilitating maintenance and replacement of the projection screen 200.

[0101] In addition, through the above settings, the detachable projection screen 200 can be adapted to different car models, and has strong versatility.

[0102] As an optional implementation, the mounting device 30 is used to mount the projection screen 200 to the sunroof 12 of the vehicle 10. Using the sunroof 12 to mount the projection screen 200 avoids occupying other space inside the vehicle, while providing a stable mounting position to ensure the fixation and stability of the projection screen 200.

[0103] Specifically, the mounting device 30 includes a first magnetic component 300 and a second magnetic component 400. The first magnetic component 300 is located on top of the projection screen 200 and connected to the projection screen 200. The second magnetic component 400 is detachably mounted on the sunroof 12 of the vehicle 10. The first magnetic component 300 and the second magnetic component 400 are magnetically connected.

[0104] Reference Figure 4 The first magnetic component 300 is located at the top of the projection screen 200 and is connected to the projection screen 200. The second magnetic component 400 is magnetically connected to the first magnetic component 300 and is used to attach the projection screen 200 to the sunroof 12 of the vehicle 10. That is, the projection screen 200 is connected to the first magnetic component 300 and the second magnetic component 400 in sequence to attach to the sunroof 12. It should be noted that the sunroof 12 is usually made of glass. Utilizing the sunroof 12 location to install the projection screen 200 avoids occupying other interior space while providing a stable mounting position, ensuring the fixation and stability of the projection screen 200.

[0105] The first magnetic component 300 and the second magnetic component 400 provide a stable connection, allowing the projection screen 200 to be securely fixed at the sunroof 12 position, while also allowing for quick installation and removal. The second magnetic component 400 provides a non-destructive installation method, avoiding damage to the vehicle interior, and allows users to quickly adjust or remove the projection screen 200 as needed.

[0106] It is understandable that the second magnetic component 400 can refer to a device that can attract glass at one end and has magnetism at the other end. The first magnetic component 300 can refer to a housing with a magnetic region.

[0107] It should be noted that the magnetic attraction between the second magnetic component 400 and the first magnetic component 300 should be magnetic attraction. That is, the magnetic force between the second magnetic component 400 and the first magnetic component 300 could be the magnetic force between a magnet and a metal, or it could be the magnetic force between two magnets with opposite polarities.

[0108] With the above configuration, the first magnetic component 300 and the second magnetic component 400 can provide a stable connection, allowing the projection screen 200 to be securely fixed at the sunroof 12 position, while also allowing for quick installation and removal. The second magnetic component 400 can be installed without damage to the first magnetic component 300, avoiding damage to the vehicle's interior. The magnetic connection also allows users to quickly adjust or remove the projection screen as needed.

[0109] As an optional implementation, the first magnetic component 300 and the second magnetic component 400 are arranged at intervals, and the second magnetic component 400 is used to attract the sunroof 12 of the vehicle 10.

[0110] Reference Figure 1 When the sunshade 13 of the vehicle 10 covers the sunroof 12, the first magnetic component 300 and the second magnetic component 400 are located on opposite sides of the sunshade 13 of the vehicle 10, and the first magnetic component 300 is installed on the sunroof 12 of the vehicle 10 through the second magnetic component 400.

[0111] This ensures the proper functioning of the sunshade 13, effectively blocking external light from interfering with the projection effect and providing a clearer projected image. Simultaneously, these features enhance the flexibility and compatibility of the vehicle projection system 20, making it suitable for various vehicle models.

[0112] With the above settings, the vehicle projection system 20 can achieve stable installation and excellent projection effect without affecting the original functions of the vehicle 10. These settings not only improve the practicality of the vehicle projection system 20 and enhance the user experience, but also increase its flexibility and adaptability.

[0113] Reference Figure 4 As an alternative implementation, along the extension direction perpendicular to the sunshade 13, the distance between the sunshade 13 and the sunroof 12 is greater than or equal to the height of the second magnetic component 400 of the vehicle projection system 20.

[0114] Understandably, the above arrangement ensures that when the projection screen 200 is installed, the second magnetic component 400 can be fully accommodated in the space between the sunshade 13 and the skylight 12 without hindering the normal operation of the sunshade 13. This arrangement allows the sunshade 13 to move freely even when the projection screen 200 is installed, effectively blocking external light and improving the clarity of the projection effect.

[0115] As an optional implementation, the first magnetic component 300 has a first magnetic surface, and the second magnetic component 400 has a second magnetic surface. The first magnetic surface and the second magnetic surface refer to the magnetic regions of the first magnetic component 300 and the second magnetic component 400, respectively. The arrangement of the first magnetic surface and the second magnetic surface allows the first magnetic component 300 and the second magnetic component 400 to be tightly connected.

[0116] The area of ​​the first magnetic surface is less than or equal to the area of ​​the second magnetic surface. That is, the second magnetic component 400 has a larger magnetic area.

[0117] The larger second magnetic surface provides greater tolerance, ensuring a good connection even if the first magnetic component 300 is misaligned during installation, thus improving the reliability and stability of the connection and reducing the risk of loosening or detachment due to improper installation. Furthermore, it allows users to easily adjust the relative positions of the first magnetic component 300 and the second magnetic component 400 according to their viewing experience, thereby changing the position of the projection screen 200 relative to the skylight 12. This convenient adjustment method enhances the user experience.

[0118] Reference Figure 5 As an optional implementation, the second magnetic component 400 includes a suction cup portion 410 and a second magnetic portion 420. The suction cup portion 410 is used to adhere to a smooth surface, i.e., the skylight 12, by means of vacuum or negative pressure.

[0119] By providing the suction cup part 410, the flexibility of the vehicle projection system 20 can be improved, allowing the projection screen 200 to be adjusted in position as needed.

[0120] By providing the second magnetic part 420, the suction cup part 410 and the second magnetic component 400 can be magnetically connected, thereby enabling quick and easy installation and disassembly, improving the reliability and stability of the connection, and allowing users to quickly adjust or remove the projection screen 200 as needed.

[0121] One end of the suction cup 410 is used to attach the sunroof 12 of the vehicle 10, and the second magnetic part 420 is connected to the other end of the suction cup 410.

[0122] In this way, the suction cup 410 can be firmly attached to the sunroof 12 of the vehicle 10, allowing for a non-destructive fixation. This design avoids damage to the vehicle's interior while allowing for quick installation and removal without tools. By fixing the suction cup to the sunroof 12, the vehicle projection system 20 can make full use of the existing structure of the vehicle 10, avoiding the need for additional space.

[0123] Reference Figure 6As an optional implementation, the first magnetic component 300 includes a housing 310 and a first magnetic part 320. The housing 310 is connected to the projection screen 200, and the first magnetic part 320 is connected to the side of the housing 310 away from the projection screen 200.

[0124] The housing 310 can provide support for the projection screen 200, so that the projection screen 200 can be stably installed inside the vehicle 10 and will not shake or fall off when the vehicle 10 is moving, thereby improving the durability and reliability of the vehicle projection system 20.

[0125] The second magnetic part 420 connects to the first magnetic part 320 of the first magnetic assembly 300, ensuring a secure connection between the suction cup part 410 and the housing 310. Through this magnetic connection, the vehicle-mounted projection system 20 can be quickly and easily installed and removed. This configuration improves the reliability and stability of the connection, allowing users to quickly adjust or remove the projection screen 200 as needed.

[0126] As an optional implementation, the magnetism of the first magnetic part 320 and the second magnetic part 420 are magnetically attracted to each other to ensure mutual attraction. That is, both the first magnetic part 320 and the second magnetic part 420 are magnets.

[0127] By ensuring that the first magnetic part 320 and the second magnetic part 420 are magnetically attracted to each other, the vehicle projection system 20 can achieve a strong magnetic attraction, thereby providing a stable connection. In addition, users can easily align and connect the housing 310 and the suction cup using simple magnetic attraction, which simplifies the installation process of the vehicle projection system 20.

[0128] As an optional implementation, the suction cup portion 410 and the second magnetic portion 420 are detachably connected.

[0129] The detachable connection provides greater flexibility and convenience. Users can quickly detach the suction cup part 410 and the second magnetic part 420 as needed for maintenance, replacement, or adjustment. This design reduces the complexity of installation and disassembly, saving time and effort.

[0130] It should be noted that the detachable connection method can be any. For example, a detachable connection can refer to a threaded connection, a snap-fit ​​connection, a magnetic connection, a pin connection, etc.

[0131] As an optional implementation, the housing 310 is detachably connected to the first magnetic part 320.

[0132] The detachable connection provides greater flexibility and convenience. Users can quickly disassemble the suction cup part 410 and the second magnetic part 420 as needed for maintenance, replacement, or adjustment. This design reduces the complexity of installation and disassembly, saving time and effort. The form of the detachable connection has been described above and will not be repeated here.

[0133] The following explanation uses the example of a detachable connection achieved by threaded connections between the suction cup part 410 and the second magnetic part 420, and between the outer shell 310 and the first magnetic part 320.

[0134] Reference Figure 7 As an optional implementation, the first magnetic component 300 further includes a connecting portion 330, which is connected between the housing 310 and the first magnetic portion 320. The length of the connecting portion 330 is adjustable to change the distance between the housing 310 and the first magnetic portion 320.

[0135] By adjusting the distance between the housing 310 and the first magnetic part 320, the user can change the position and angle of the projection screen 200 to obtain a better projection effect. This adjustability allows the in-vehicle projection system 20 to adapt to different vehicle interior layouts and user preferences, providing a better user experience. Furthermore, the above settings may also help reduce the impact of vibration or shock on the projection screen 200, improving the durability and stability of the in-vehicle projection system 20.

[0136] It is understood that the form of the connecting part 330 can be varied. For example, the housing 310 has a slide rail, and the first magnetic part 320 is connected to a slider, which is mounted on the slide rail. The user adjusts the distance between the housing 310 and the first magnetic part 320 by changing the position of the slider. Another example is that the housing 310 and the first magnetic part 320 are threadedly connected by a screw, and the user can change the distance between them by altering the degree of thread connection. These are merely examples; the connecting part 330 can be selected according to the actual situation.

[0137] The following explanation uses the example of a threaded connection between the outer casing 310 and the first magnetic part 320 achieved through a screw connector.

[0138] Reference Figure 7 As an optional implementation, the housing 310 has a receiving cavity 311 and a through hole 312 communicating with the receiving cavity 311. The receiving cavity 311 is used to receive internal components and is connected to the outside through the through hole 312.

[0139] Reference Figure 8The housing 310 also includes a bolt 331 for connecting the housing 310 to the first magnetic part 320. The first magnetic assembly 300 also includes a limiting member 340 located within the receiving cavity 311. The limiting member 340 is disposed around the through hole 312, and the limiting member 340 and the housing 310 together form a limiting space. The bolt 331 includes a head 3311 and a first stud 3312. The head 3311 is located within the limiting space, and the limiting member 340 can ensure that the head 3311 of the bolt 331 is fixed within the limiting space, preventing the bolt 331 from rotating during use. By providing the limiting member 340, the stability and reliability of the bolt 331 on the housing 310 can be improved, thereby ensuring a stable connection between the housing 310 and the first magnetic part 320.

[0140] One end of the first stud 3312 is connected to the head 3311, and the other end is provided with a through hole 312. The first magnetic part 320 has a first threaded hole 321 corresponding to the first stud 3312, and the outer shell 310 is threadedly connected to the first threaded hole 321 of the first magnetic part 320 through the head 3311 and the first stud 3312.

[0141] The first stud 3312 is connected to the threaded hole of the first magnetic part 320 through the through hole 312, which can realize a stable connection between the outer shell 310 and the first magnetic part 320.

[0142] With the above configuration, the housing 310 and the first magnetic part 320 can be firmly connected by the limiting member 340 and the bolt 331. The threaded connection can improve the installation stability and usage effect of the projection screen 200, thereby enhancing the durability and adaptability of the vehicle projection system 20 and ensuring good performance under different usage conditions. On the other hand, it can change the distance between the housing 310 and the first magnetic part 320, allowing users to freely change the position and angle of the projection screen 200 to obtain a better projection effect.

[0143] Reference Figure 9 As an optional implementation, the first magnetic component 300 further includes a self-locking part 350, which is connected between the housing 310 and the first magnetic part 320. The self-locking part 350 can stop the movement between the housing 310 and the first magnetic part 320 to prevent the housing 310 from disengaging from the first magnetic part 320.

[0144] Specifically, the self-locking part 350 is configured to lock the housing 310 and the first magnetic part 320 when the distance between the housing 310 and the first magnetic part 320 is at its maximum. That is, the self-locking part 350 can ensure that the movement distance between the housing 310 and the first magnetic part 320 does not exceed the maximum distance, preventing unstable connection or detachment due to over-adjustment, and improving the durability of the vehicle projection system 20 and user safety.

[0145] The self-locking part 350 and the connecting part 330 are spaced apart, which allows the self-locking part 350 and the connecting part 330 to operate independently and avoid conflict. In this way, the connecting part 330 can freely adjust the distance between the outer shell 310 and the first magnetic part 320, while the self-locking part 350 ensures that the outer shell 310 and the first magnetic part 320 complete the movement within a preset distance.

[0146] It is understood that the self-locking part 350 can take various forms. For example, the self-locking part 350 can be a clamp matching the maximum moving distance, with both the outer shell 310 and the first magnetic part 320 located within the clamp. When the connecting part 330 moves the outer shell 310 and the first magnetic part 320 relative to each other to the maximum distance, the clamp can prevent the outer shell 310 and the first magnetic part 320 from continuing to move, thus achieving self-locking. Another example is that the self-locking part 350 can be an elastic element with a certain elasticity. The elastic element can rebound after the maximum distance moved by the outer shell 310 and the first magnetic part 320 to lock the movement between the outer shell 310 and the first magnetic part 320. These are merely examples; the self-locking part 350 can be selected according to actual circumstances.

[0147] The following explanation uses spring 351 as an example to illustrate the self-locking part 350.

[0148] Reference Figure 9 As an optional implementation, the self-locking part 350 includes a spring 351. It is understood that the spring 351 has elastic properties and can be compressed or stretched under the action of external force, and return to its original shape after the external force is released, so that the structure connected at both ends of the spring 351 can automatically lock or release when needed, thereby improving safety and reliability.

[0149] Spring 351 is sleeved on first stud 3312. By sleeved on first stud 3312, the interaction between first stud 3312 and spring 351 can be avoided. The structure of connecting part 330 and self-locking part 350 can be simplified. That is, spring 351 can apply elastic force on the axis of stud, thereby enhancing the locking effect.

[0150] The opposite ends of the spring 351 abut against the outer casing 310 and the first magnetic part 320, respectively. When the distance between the outer casing 310 and the first magnetic part 320 changes, the spring 351 can automatically adjust its length, thereby achieving automatic locking or releasing. By setting the spring 351, it is ensured that the connection between the outer casing 310 and the first magnetic part 320 remains stable under different usage conditions, thus achieving a self-locking effect.

[0151] Reference Figure 4As an optional implementation, the number of second magnetic components 400 can be multiple, which can increase the stability and load-bearing capacity of the vehicle projection system 20. By fixing it at multiple locations, the vehicle projection system 20 can better distribute the load, reduce the pressure on a single suction cup, and thus improve the overall stability and durability.

[0152] Correspondingly, the first magnetic component 300 includes a plurality of first magnetic parts 320, and the plurality of first magnetic parts 320 correspond one-to-one with the second magnetic parts 420 of the plurality of second magnetic components 400, so as to ensure that each suction cup can be connected to the corresponding second magnetic part 420, thereby improving the reliability of the connection.

[0153] Multiple first magnetic parts 320 are spaced apart on the housing 310. This spacing helps to evenly distribute the load and stress, preventing stress concentration that could lead to damage. This arrangement improves the stability and durability of the vehicle projection system 20, while also allowing for flexible installation to suit different vehicles 10 and user needs.

[0154] Reference Figure 10 As an optional implementation, the suction cup portion 410 includes a suction cup body 411 and a second stud 412. The suction cup body 411 is used to attach to the sunroof 12 of the vehicle 10. The second stud 412 is connected to the outside of the suction cup body 411 and is fixedly connected to the suction cup body 411; the second magnetic portion 420 has a second threaded hole 421 corresponding to the second stud 412, and the suction cup body 411 is threadedly connected to the second threaded hole 421 of the second magnetic portion 420 through the second stud 412. The suction cup body 411 is connected to the threaded hole of the second magnetic portion 420 through the second stud 412.

[0155] With the above configuration, a stable connection can be formed between the suction cup body 411 and the second magnetic part 420 through the second stud 412. The threaded connection can improve the installation stability and usage effect of the projection screen 200, thereby enhancing the durability and adaptability of the vehicle projection system 20 and ensuring good performance under different usage conditions. On the other hand, the second magnetic part 420 and the suction cup body 411 can be disassembled to replace the suction cup body 411 according to the usage.

[0156] Reference Figure 7 Figure 9 shows an optional implementation where the housing 310 includes an upper housing 313, a lower housing 314, and a side plate 315 connecting the upper housing 313 and the lower housing 314. The upper housing 313 and the lower housing 314 cooperate with each other to effectively protect the internal projection screen 200 from the influence of the external environment and ensure the structural integrity and durability of the vehicle projection system 20.

[0157] The side plate 315 increases the structural strength and stability of the upper housing 313 and the lower housing 314, preventing relative movement between them. Furthermore, the side plate 315 provides additional protection, preventing dust and debris from entering the interior of the housing 310.

[0158] An opening (not shown in the figure) is formed between the upper housing 313 and the lower housing 314, through which the projection screen 200 extends outside the housing 310 or enters the housing 310. The opening allows the projection screen 200 to be stored inside the housing 310 when not in use, thereby protecting the projection screen 200 from damage. When needed, the projection screen 200 can extend out of the housing 310 through the opening to provide projection functionality.
