[0001] This utility model relates to the field of vehicle display technology, specifically a multi-screen vehicle entertainment display. Background Technology

[0002] With the integration of the automotive industry and consumer electronics technology, in-vehicle displays have gradually expanded from a single instrument panel function to multiple scenarios such as in-vehicle entertainment and information interaction, becoming an important component for enhancing the riding experience.

[0003] However, most existing in-vehicle displays are single-screen designs. Even in models equipped with multiple screens, there are often problems with the main and secondary screens having independent content and being unable to play synchronously. This makes it difficult for passengers in the front passenger seat and the rear seat to share the same video content, hindering interactive communication and greatly reducing the interactivity and fun of in-vehicle entertainment, making it difficult to meet the collaborative entertainment needs of multiple passengers.

[0004] Therefore, we propose a multi-screen in-vehicle entertainment display to address the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a multi-screen in-vehicle entertainment display screen to solve the problem mentioned in the background art that most existing in-vehicle displays use a single screen, which makes it difficult for passengers in the front passenger seat and the rear seat to share the same video content, making it impossible to form interactive communication, greatly reducing the interactivity and fun of in-vehicle entertainment, and making it difficult to meet the collaborative entertainment needs of multiple people traveling in a car.

[0006] This utility model provides the following technical solution: a multi-screen in-vehicle entertainment display screen, including a main display and a secondary display. Both the main display and the secondary display are equipped with display screens. The main display and the secondary display are electrically connected. A support block is fixed to the back of the secondary display. A rotating rod is fixed to the support block. A mounting base is rotatably sleeved on the outer ring of the rotating rod. A U-shaped frame is fixed to the end of the mounting base. A rotating component and a driving component are installed on the U-shaped frame. An extension frame is slidably connected inside the U-shaped frame. A locking component is installed on the U-shaped frame. A collar is fixed to the end of the extension frame. A car seat rod is fixedly installed inside the collar by bolts.

[0007] Preferably, the rotating assembly includes a connecting shaft fixedly connected to the end of the rotating rod, a worm gear fixedly sleeved on the outer ring of the connecting shaft, a support plate fixedly fixed to the end of the U-shaped frame, a worm rotating on the support plate, and the worm meshing with the worm gear.

[0008] Preferably, the drive assembly includes a rocker arm fixedly connected to the bottom surface of the worm gear.

[0009] Preferably, the drive assembly includes a mounting bracket fixedly connected to the U-shaped frame, a motor fixed on the mounting bracket, a T-shaped shaft fixed to the output end of the motor, an electromagnet mounted on the T-shaped shaft, a T-shaped groove opened at the top of the worm gear, a permanent magnet fixed to the top wall of the inner wall of the T-shaped groove, the T-shaped shaft rotatably connected to the T-shaped groove, and the permanent magnet and the electromagnet in contact.

[0010] Preferably, the locking assembly includes a screw hole formed on the U-shaped frame, a screw is threaded into the screw hole, a nut is threaded onto the outer ring of the screw, and the nut is fitted into the U-shaped frame.

[0011] Preferably, the extension frame has multiple insertion holes arranged linearly, and the screw is inserted into the insertion holes.

[0012] This utility model has the following beneficial effects: 1. This entertainment display screen achieves synchronous transmission and playback of content between the main and secondary screens through electrical connection and collaborative design between the main and secondary screens. This allows passengers in the front passenger seat and the rear seat to watch the same video content simultaneously. This design breaks the limitation that passengers in different positions cannot share video content, making it convenient for everyone to share their feelings and exchange opinions during the viewing process. It effectively improves the lack of interactivity and fun in existing in-vehicle entertainment and truly meets the collaborative entertainment needs of multiple passengers.

[0013] 2. Regarding the adjustment of the secondary display angle, it has both manual and automatic adjustment modes, which is highly flexible. When the rear seat personnel can operate it themselves, they can manually turn the joystick to adjust the angle, which is simple and direct. When it is inconvenient for the rear seat personnel to adjust, the passenger in the front seat can control the secondary display to adjust the angle automatically through the main display, without the rear seat personnel having to do it themselves, which further improves the convenience of use and ensures that users with different needs can find a comfortable viewing angle, thus enhancing viewing comfort.

[0014] 3. The secondary display allows for easy adjustment of the distance between the secondary display and the rear passengers through simple operations such as loosening the nuts, moving the extension bracket, and relocking. This avoids unclear viewing due to excessive distance and ensures that the rear passengers can always view the content within a clear field of vision, further optimizing the viewing experience. At the same time, the locking components can firmly fix the position of the extension bracket, ensuring that the secondary display remains stable during vehicle movement and will not shift due to bumps, thus ensuring the stability of the viewing process.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0026] This embodiment aims to address the issues in in-vehicle multi-screen entertainment scenarios, such as the difficulty for passengers in the front passenger seat and rear seat to simultaneously view video content, and the inflexible viewing angle of the rear seat secondary display 2. Please refer to [link / reference]. Figure 1 - Figure 6A multi-screen in-vehicle entertainment display includes a main display 1 and a secondary display 2. Both the main display 1 and the secondary display 2 are equipped with display screens 3. The main display 1 and the secondary display 2 are electrically connected, enabling data synchronization and supporting split-screen playback of the same video content. This allows the front passenger and rear seat passengers to watch and interact simultaneously, significantly improving the interactivity and comfort of in-vehicle entertainment. A support block 4 is fixed to the back of the secondary display 2, and a rotating rod 5 is fixed to the support block 4. A mounting base 6 is rotatably fitted onto the outer ring of the rotating rod 5. A U-shaped bracket 9 is fixed to the end of the mounting base 6, and a rotating component 7 and a driving component 8 are mounted on the U-shaped bracket 9.

[0027] The rotating assembly 7 includes a connecting shaft 71 fixedly connected to the end of the rotating rod 5. A worm gear 72 is fixedly sleeved on the outer ring of the connecting shaft 71. A support plate 73 is fixedly fixed to the end of the U-shaped frame 9. A worm 74 rotates on the support plate 73. The worm 74 meshes with the worm gear 72.

[0028] The drive assembly 8 includes a rocker arm 801 that is fixedly connected to the bottom surface of the worm gear 74.

[0029] In this embodiment, the main display 1 is installed in front of the passenger seat as the main control terminal, and the secondary display 2 is bolted to the seat arm 12 in the rear seat. The two are electrically connected to achieve data transmission. In use, the user can control the playback of content on the secondary display 2 through the main display 1, so that the passenger and rear seat passengers can watch the same video content synchronously, which facilitates sharing opinions and enhances entertainment.

[0030] When the viewing angle of the secondary display 2 needs to be adjusted and the person in the back seat can adjust it manually, it can be operated manually. In the initial state, the electromagnet 84 on the T-shaped shaft 83 at the output end of the motor 82 in the drive assembly 8 is not energized. The electromagnet 84 and the permanent magnet 86 on the top wall of the T-shaped groove 85 of the worm 74 are only in contact but without attraction. The T-shaped shaft 83 can rotate freely in the T-shaped groove 85. Then, the rocker arm 801 in the drive assembly 8 is manually rotated. The rocker arm 801 drives the worm 74 to rotate around the support plate 73. Because the worm 74 and the worm wheel 72 are meshed with each other, the worm wheel 72 will drive the connecting shaft 71 to rotate with the rotation of the worm 74. The connecting shaft 71 is fixedly connected to the rotating rod 5. The rotating rod 5 is connected to the secondary display 2 through the support block 4, and the outer ring of the rotating rod 5 is rotatably sleeved with the mounting base 6. Finally, the rotating rod 5 will drive the secondary display 2 to rotate around the mounting base 6, realizing the manual adjustment of the viewing angle of the secondary display 2 and meeting the needs of the person in the back seat for different viewing angles. Example

[0031] This embodiment aims to address the problem of difficulty in adjusting the angle of the secondary display due to operational inconvenience or lack of adjustment skills among rear-seat passengers. This embodiment is an improvement upon Embodiment 1. For details, please refer to [link to Embodiment 1]. Figure 6 - Figure 8The drive assembly 8 includes a mounting bracket 81 fixedly connected to the U-shaped frame 9. A motor 82 is fixed on the mounting bracket 81. A T-shaped shaft 83 is fixed to the output end of the motor 82. An electromagnet 84 is mounted on the T-shaped shaft 83. A T-shaped groove 85 is opened at the top of the worm gear 74. A permanent magnet 86 is fixed to the inner top wall of the T-shaped groove 85. The T-shaped shaft 83 is rotatably connected to the T-shaped groove 85. The permanent magnet 86 is in contact with the electromagnet 84.

[0032] In this embodiment: when the rear seat occupants cannot adjust themselves, the front passenger can make automatic control adjustments. Since the electromagnet 84 on the T-shaped shaft 83 at the output end of the motor 82 in the drive assembly 8 is not energized in the initial state, the electromagnet 84 and the permanent magnet 86 on the top wall of the T-shaped groove 85 of the worm gear 74 are only in contact but have no attraction force, and the T-shaped shaft 83 can rotate freely in the T-shaped groove 85.

[0033] If angle adjustment is required, the passenger can issue a control command through the main display 1 to energize the electromagnet 84. The energized electromagnet 84 and permanent magnet 86 attract each other, forming a single unit. Since the electromagnet 84 is fixedly connected to the T-shaft 83 and the permanent magnet 86 is fixedly connected to the worm gear 74, the attraction between the electromagnet 84 and the permanent magnet 86 creates relative braking between the T-shaft 83 and the worm gear 74. At this point, the motor 82 is activated, and its output drives the T-shaft 83 to rotate. The T-shaft 83 then synchronously drives the worm gear 74 to rotate. The worm gear 74 meshes with the worm wheel 72, which in turn drives the connecting shaft 71 and the rotating rod 5 to rotate. Ultimately, this causes the secondary display 2 to rotate around the mounting base 6, achieving automatic adjustment of the viewing angle of the secondary display 2 and further improving ease of use and viewing comfort. Example

[0034] This embodiment aims to address the problem of unclear viewing for passengers in the back seat due to the excessive distance between the secondary display 2 and the passenger. This embodiment is an improvement upon Embodiment 1. For details, please refer to [link to Embodiment 1]. Figure 9 An extension frame 10 is slidably connected inside the U-shaped frame 9. A locking assembly 91 is installed on the U-shaped frame 9. A collar 11 is fixed to the end side of the extension frame 10. A seat rod 12 is fixedly installed inside the collar 11 by bolts. The locking assembly 91 includes a screw hole 911 opened on the U-shaped frame 9. A screw 912 is installed in the screw hole 911. A nut 913 is installed in the outer ring of the screw 912. The nut 913 fits against the U-shaped frame 9.

[0035] The extension frame 10 has multiple insertion holes 101 arranged linearly, and the screw 912 is inserted into the insertion holes 101.

[0036] In this embodiment: when the viewing distance of the secondary display 2 is too far and needs to be adjusted, first loosen the nut 913 on the outer ring of the screw 912 in the locking assembly 91, and then unscrew the screw 912 from the current insertion hole 101 of the extension frame 10 to release the limitation of the screw 912 on the extension frame 10. At this time, the U-shaped frame 9 can be pulled. Since the extension frame 10 and the U-shaped frame 9 are slidably connected, the extension frame 10 can slide inside the U-shaped frame 9. The secondary display 2 connected to the U-shaped frame 9 will move synchronously to a suitable distance for the person in the back seat to view clearly. After the distance adjustment is completed, align the screw 912 with the corresponding insertion hole 101 on the extension frame 10 and screw it in. Then tighten the nut 913 so that the nut 913 fits tightly with the U-shaped frame 9. Through the insertion and cooperation of the screw 912 and the insertion hole 101 and the locking and fixing of the nut 913, the position of the extension frame 10 is locked, thereby fixing the extension distance of the secondary display 2 and ensuring that the position of the secondary display 2 is stable during the viewing process.
