Description

Technical Field

[0001] This utility model belongs to the field of automotive roof technology, and more specifically, it relates to an automotive roof with integrated multimedia functions. Background Technology

[0002] A car roof is a decorative structure that covers the interior of a vehicle. It is usually composed of multiple layers of composite materials (such as fabric, foam, plastic or synthetic leather) and a supporting frame, and has functions such as aesthetics, sound insulation, heat insulation, waterproofing, dustproofing and safety protection.

[0003] Current car models often integrate lighting systems, sunroofs, sunshades, or sensors into the roof. Some high-end models use displays, solar charging panels, or lightweight and environmentally friendly materials, combining practicality and a sense of technology, and integrating multimedia functions inside the car roof.

[0004] According to the electric flipping mechanism for an automotive roof display screen disclosed in Chinese Patent Publication No. CN217347678U, micro motors are respectively set at both ends of the rotating side of the back plate. The torque required to flip the display screen is shared by the two micro motors. The display screen can be directly driven to flip from both ends of the back plate by using two micro motors.

[0005] However, the aforementioned devices, combined with existing automotive roof displays, mostly adopt a fixed flip-up structure, which can only achieve basic unfolding and storage functions. Their adjustment dimensions are limited to a single axis of rotation, lacking the ability to adaptively adjust height and multiple angles. As a result, rear-seat passengers facing the side need to significantly adjust their sitting posture or turn to the side to view the screen, leading to problems such as visual axis shift and neck fatigue, which significantly affects the immersive experience. Utility Model Content

[0006] In view of the problem that the adjustment dimension of the car roof display screen in the related technology is limited to a single axis rotation and lacks the ability to adaptively adjust the height and multiple angles, this utility model proposes a car roof with integrated multimedia functions to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model is a car roof with integrated multimedia functions, including a car roof body and a display screen body. The car roof body is provided with an opening and closing rotation mechanism inside. The rotating end of the opening and closing rotation mechanism is provided with an angle self-locking mechanism. The opening and closing rotation mechanism is also provided with a sliding lifting mechanism. The lifting end of the sliding lifting mechanism is connected to the display screen body. The car roof body is provided with a switch mechanism inside.

[0009] By pulling the opening and closing rotation mechanism, the display screen body is detached from the interior of the car roof body. The fixed end of the sliding lifting mechanism is released, and the lifting end of the sliding lifting mechanism drives the display screen body to adjust its height. The rotating end of the opening and closing rotation mechanism is rotated to adjust the viewing angle of the display screen body.

[0010] Furthermore, the opening and closing rotation mechanism includes a flipping block, a flipping shaft is fixedly connected inside the flipping block, the flipping shaft is rotatably connected inside the car roof body, one end of the flipping block is rotatably connected to a bracket frame, and the display screen body is located inside the bracket frame.

[0011] Furthermore, the angle self-locking mechanism includes a rotating disk, one end of which is fixedly connected to the surface of the flipping block, and the other end of which is rotatably connected to the inside of the support frame.

[0012] Furthermore, the rotating disk has multiple limiting grooves on its surface, a moving rod is slidably connected inside the support frame, one end of the moving rod is fixedly connected to a locking ball that matches the limiting groove, a spring is fixedly connected inside the support frame, a limiting plate is fixedly connected to the surface of the moving rod, the limiting plate is slidably connected inside the support frame, one end of the spring is fixedly connected to the surface of the limiting plate, the locking ball is slidably connected inside the support frame, and the locking ball is movably connected inside the limiting groove.

[0013] Furthermore, the sliding lifting mechanism includes a limiting rod, which is fixedly connected inside the support frame. A lifting frame is slidably connected to the surface of the limiting rod, and the lifting frame is also slidably connected inside the support frame. The display screen body is fixedly installed on the surface of the lifting frame, and a handle is fixedly connected to one side of the lifting frame.

[0014] Furthermore, a fixing block is fixedly connected to one side of the lifting frame, a fixing bolt is threaded onto the surface of the fixing block, a fixing plate is sleeved on the surface of the fixing bolt, and the fixing bolt is slidably connected inside the support frame.

[0015] Furthermore, the switching mechanism includes a transverse block, the two ends of which are slidably connected to the interior of the car roof body. A second spring is fixedly connected to one side of the transverse block, one end of the second spring is fixedly connected to the interior of the car roof body, and a switch rod is slidably connected to both ends of the transverse block. The switch rod is fixedly connected to the interior of the car roof body, and the second spring is sleeved on the surface of the switch rod.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model uses a pulling opening and closing rotating mechanism to detach the display screen body from the interior of the car roof body, allowing the lifting end of the sliding lifting mechanism to drive the display screen body to adjust its height. Rotating the rotating end of the opening and closing rotating mechanism adjusts the viewing angle of the display screen body, thus completing multi-angle adjustment of the display screen body. Based on dual-degree-of-freedom collaborative control, the display screen can match the optimal viewing height and horizontal deflection angle according to the passenger's sitting posture data, forming a dynamic golden angle projection area, allowing side passengers to obtain a forward immersive viewing experience without changing their sitting posture.

[0018] 2. This utility model uses a rotating bracket frame to drive the display screen body to adjust its angle in multiple degrees of freedom. During this process, the locking ball in the ball joint structure slides along the trajectory of the limiting groove on the rotating disk surface, synchronously compressing the spring to store energy. When the angle matches the target value, the spring releases its potential energy to push the limiting plate to slide in a straight line. The linkage moving rod precisely embeds the locking ball into the limiting groove and locks it in place, forming a three-point contact mechanical interlock. This mechanism maintains its self-locking accuracy even under vehicle acceleration impact conditions, achieving millimeter-level stable control of the display screen body's posture during dynamic driving.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0030] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0031] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0032] Please see Figures 1-7 As shown, this utility model is a car roof with integrated multimedia functions, including a car roof body 1 and a display screen body 2. The car roof body 1 is provided with an opening and closing rotation mechanism 3 inside. The rotating end of the opening and closing rotation mechanism 3 is provided with an angle self-locking mechanism 4. The opening and closing rotation mechanism 3 is also provided with a sliding lifting mechanism 5 inside. The lifting end of the sliding lifting mechanism 5 is connected to the display screen body 2. The car roof body 1 is provided with a switch mechanism 6 inside.

[0033] By pulling the opening and closing rotation mechanism 3, the display screen body 2 is disengaged from the interior of the car roof body 1. The fixed end of the sliding lifting mechanism 5 is released, and the lifting end of the sliding lifting mechanism 5 drives the display screen body 2 to adjust its height. The rotating end of the opening and closing rotation mechanism 3 is rotated to adjust the viewing angle of the display screen body 2.

[0034] By opening the switch mechanism 6, pulling the opening and closing rotation mechanism 3 causes the display screen body 2 to detach from the interior of the car roof body 1. The fixed end of the sliding lifting mechanism 5 is released, allowing the lifting end of the sliding lifting mechanism 5 to drive the display screen body 2 to adjust its height. After this is completed, the fixed end of the sliding lifting mechanism 5 is locked, and the rotating end of the opening and closing rotation mechanism 3 is rotated to adjust the viewing angle of the display screen body 2. At the same time, the angle self-locking mechanism 4 self-locks the rotating end of the opening and closing rotation mechanism 3, thus completing the multi-angle adjustment of the display screen body 2.

[0035] By pulling the opening and closing rotation mechanism 3, the display screen body 2 is separated from the interior of the car roof body 1, and the lifting end of the sliding lifting mechanism 5 drives the display screen body 2 to adjust its height. By rotating the rotating end of the opening and closing rotation mechanism 3, the viewing angle of the display screen body 2 can be adjusted, thus completing the multi-angle adjustment of the display screen body 2. Based on dual-degree-of-freedom collaborative control, the display screen can match the optimal viewing height and horizontal deflection angle according to the passenger's sitting posture data to form a dynamic golden angle projection area, so that passengers facing the side can obtain a positive immersive viewing experience without changing their sitting posture.

[0036] Furthermore, in specific applications, the connection between the automotive headliner display and the vehicle infotainment system is based on an in-vehicle Ethernet + domain controller architecture. Audio and video signals are transmitted via physical wiring harnesses (such as LVDS / HDMI interfaces) or wireless protocols (Wi-Fi 6 / Bluetooth 5.3), while control commands are synchronized via CAN FD or FlexRay bus. The process is as follows: after the display is powered on, it sends a device ID authentication request to the vehicle gateway and establishes a communication link through the AES-256 encrypted handshake protocol. The vehicle infotainment system pushes multimedia content (navigation, audio and video) to the headliner display in H.265 encoding format and receives its touch / voice feedback signals. Through the SOA service framework, computing resources are dynamically allocated (such as 3D rendering being completed by the intelligent driving domain) to achieve multi-screen content synchronization and low-latency interaction (≤50ms). An integrated redundant ring network (such as TSN time-sensitive network) ensures signal stability under extreme conditions, ultimately forming an integrated control closed loop of "cloud-vehicle-screen". This is existing technology and will not be elaborated further.

[0037] In one embodiment, the opening and closing rotation mechanism 3 includes a flipping block 301, a flipping shaft 302 is fixedly connected inside the flipping block 301, the flipping shaft 302 is rotatably connected inside the car roof body 1, one end of the flipping block 301 is rotatably connected to a bracket frame 303, and the display screen body 2 is located inside the bracket frame 303.

[0038] By flipping the bracket frame 303, the bracket frame 303 drives the display screen body 2 to move synchronously. The bracket frame 303 drives the flipping block 301 to move, causing the flipping block 301 to drive the flipping shaft 302 to rotate inside the car roof body 1, thereby causing the bracket frame 303 to flip the display screen body 2 out of the car roof body 1. When it is necessary to adjust the angle of the display screen body 2, the bracket frame 303 is rotated so that the bracket frame 303 rotates on the surface of the flipping block 301, thereby causing the display screen body 2 to change its angle. The angle self-locking mechanism 4 then stabilizes the bracket frame 303.

[0039] In one embodiment, the angle self-locking mechanism 4 includes a rotating disk 401. One end of the rotating disk 401 is fixedly connected to the surface of the flipping block 301, and the other end of the rotating disk 401 is rotatably connected to the inside of the support frame 303. The surface of the rotating disk 401 is provided with a plurality of limiting grooves 402. A moving rod 404 is slidably connected inside the support frame 303. One end of the moving rod 404 is fixedly connected to a locking ball 405 that is adapted to the limiting groove 402. A spring 403 is fixedly connected inside the support frame 303. A limiting plate 406 is fixedly connected to the surface of the moving rod 404. The limiting plate 406 is slidably connected inside the support frame 303. One end of the spring 403 is fixedly connected to the surface of the limiting plate 406. The locking ball 405 is slidably connected inside the support frame 303 and movably connected inside the limiting groove 402.

[0040] By rotating the bracket frame 303, the bracket frame 303 rotates on the surface of the rotating disk 401. At the same time, the locking ball 405 slides on the surface of the limiting groove 402, so that the locking ball 405 continuously compresses the spring 403. After adjustment, the spring 403 will drive the limiting plate 406 to slide through the rebound force, so that the limiting plate 406 drives the moving rod 404 to slide inside the bracket frame 303, so that the moving rod 404 drives the locking ball 405 to engage in the limiting groove 402, completing the connection with the rotating disk 401, realizing self-locking of the rotation angle, and improving the stability of the display screen body 2 when the vehicle is moving.

[0041] In one embodiment, the sliding lifting mechanism 5 includes a limiting rod 501, which is fixedly connected inside the support frame 303. A lifting frame 502 is slidably connected to the surface of the limiting rod 501, and the lifting frame 502 is also slidably connected inside the support frame 303. The display screen body 2 is fixedly installed on the surface of the lifting frame 502. A handle 503 is fixedly connected to one side of the lifting frame 502, and a fixing block 504 is fixedly connected to one side of the lifting frame 502. A fixing bolt 505 is threadedly connected to the surface of the fixing block 504, and a fixing plate 506 is sleeved on the surface of the fixing bolt 505. The fixing bolt 505 is slidably connected inside the support frame 303.

[0042] Loosen the fixing bolt 505, causing the fixing bolt 505 to move the fixing plate 506 away from the surface of the bracket frame 303. Then pull the handle 503, causing the handle 503 to move the lifting frame 502 inside the bracket frame 303. The lifting frame 502 slides on the surface of the limit rod 501, while simultaneously moving the fixing block 504. The display screen body 2 is raised and lowered by the lifting frame 502. When it reaches the appropriate position, rotate the fixing bolt 505, causing the fixing bolt 505 to move the fixing plate 506 to press against the surface of the bracket frame 303, thus fixing the fixing block 504 and completing the height adjustment of the display screen body 2.

[0043] In one embodiment, the switch mechanism 6 includes a transverse block 601, with both ends of the transverse block 601 slidably connected to the interior of the car roof body 1. A second spring 602 is fixedly connected to one side of the transverse block 601, with one end of the second spring 602 fixedly connected to the interior of the car roof body 1. A switch rod 603 is slidably connected to both ends of the transverse block 601, with the switch rod 603 fixedly connected to the interior of the car roof body 1. The second spring 602 is sleeved on the surface of the switch rod 603.

[0044] Slide the transverse block 601 to compress the second spring 602. The transverse block 601 moves on the surface of the switch rod 603, so that the transverse block 601 is hidden inside the car roof body 1. Then the bracket frame 303 is flipped. When closed, the bracket frame 303 is reset. The second spring 602 drives the transverse block 601 to move, so that the transverse block 601 is disengaged from the inside of the car roof body 1. The transverse block 601 contacts the bottom of the bracket frame 303 to support the bracket frame 303, thus completing the recycling and fixing of the bracket frame 303.

[0045] Through the above technical solution, 1. By flipping the bracket frame 303, the bracket frame 303 drives the display screen body 2 to move synchronously. The bracket frame 303 drives the flipping block 301 to move, causing the flipping block 301 to drive the flipping shaft 302 to rotate inside the car roof body 1, thereby causing the bracket frame 303 to flip the display screen body 2 out of the car roof body 1; when it is necessary to adjust the angle of the display screen body 2, rotate the bracket frame 303 so that the bracket frame 303 rotates on the surface of the flipping block 301, thereby causing the display screen body 2 to change angle. Loosen the fixing bolt 505, so that... The fixing bolt 505 drives the fixing plate 506 to detach from the surface of the bracket frame 303. Then, the handle 503 is pulled, causing the handle 503 to slide the lifting frame 502 inside the bracket frame 303. The lifting frame 502 slides on the surface of the limit rod 501, while simultaneously moving the fixing block 504. The display screen body 2 is raised and lowered by the lifting frame 502. When it reaches the appropriate position, the fixing bolt 505 is rotated, causing the fixing bolt 505 to drive the fixing plate 506 to press against the surface of the bracket frame 303, thus fixing the fixing block 504 and completing the height adjustment of the display screen body 2.

[0046] 2. The display screen body 2 is driven by the rotating bracket frame 303 to perform multi-degree-of-freedom angle adjustment. During this process, the locking ball 405 in the ball joint structure slides along the trajectory of the limiting groove 402 on the surface of the rotating disk 401, and synchronously compresses the spring 403 to store energy. When the angle matches the target value, the spring 403 releases potential energy to push the limiting plate 406 to slide in a straight line. The linkage moving rod 404 accurately embeds the locking ball 405 into the limiting groove 402 to lock it in place, forming a three-point contact mechanical interlock. This mechanism maintains self-locking accuracy under vehicle acceleration impact conditions, and achieves millimeter-level stable control of the attitude of the display screen body 2 during dynamic driving.
