Detailed Implementation

[0023] 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.

[0024] like Figures 1 to 11 As shown, this utility model provides a dual-sided drive screen assembly device operating on a vehicle roof, including a fixed base plate assembly 1. The bottom of the fixed base plate assembly 1 has a storage groove, inside which a decorative panel assembly 2 is installed. A left drive assembly 3 and a right drive assembly 4 are symmetrically installed on the bottom of the fixed base plate assembly 1. A screen rear shell assembly 5 is installed at the bottom of the left drive assembly 3 and the right drive assembly 4. A display screen assembly 6 is installed inside the screen rear shell assembly 5. A left lock assembly 7 and a right lock assembly are symmetrically fixedly connected to the top of the fixed base plate assembly 1. The component 8, and the left locking component 7 and the right locking component 8 are used in conjunction with the screen back shell component 5. The top of the fixed base plate component 1 is fixedly connected to the screen module driver and electronic lock component 9, PCBA component 10 and pull wire component 11 respectively. The screen module driver and electronic lock component 9 is fixedly connected to the left driving component 3, the right driving component 4, the left locking component 7 and the right locking component 8 respectively through the flexible shaft pull wire. The top of the fixed base plate component 1 is installed with the wire harness component 12 through the plug-in component. The bottom of the fixed base plate component 1 is installed with the protective cover component 13 through the buckle.

[0025] refer to Figure 1 and Figure 4 The left drive component 3 and the right drive component 4 are modules with the same structure, and the left lock component 7 and the right lock component 8 are modules with the same structure.

[0026] This embodiment adopts a modular design with identical structures for the left drive assembly 3 and the right drive assembly 4, as well as the left lock assembly 7 and the right lock assembly 8, achieving standardization and universality of components. This design not only reduces manufacturing difficulty and cost but also facilitates assembly and subsequent maintenance and replacement, while ensuring consistency in both-sided drive and locking actions, thus improving the stability of equipment operation.

[0027] refer to Figure 1 , Figure 5 and Figure 6 The cable assembly 11 includes a first flexible shaft cable 111 for connecting the screen module driver and electronic lock assembly 9 and the left drive assembly 3 and the right drive assembly 4, and a second flexible shaft cable 112 for connecting the screen module driver and electronic lock assembly 9 and the left lock assembly 7 and the right lock assembly 8.

[0028] In this embodiment, the drive assembly and the lock assembly are connected by the first flexible shaft pull wire 111 and the second flexible shaft pull wire 112 respectively, which clarifies the path of power transmission, thereby making the power transmission more precise and efficient, avoiding mutual interference between power transmissions of different functions, optimizing the power transmission structure, and facilitating the layout design and subsequent debugging of the equipment.

[0029] refer to Figure 7 and Figure 8 Both the left locking assembly 7 and the right locking assembly 8 include a locking tongue structure 71, which can be released from the locked state under the drive of the second flexible shaft pull cable 112.

[0030] In this embodiment, the locking state is released by driving the locking tongue structure 71 of the left locking assembly 7 and the right locking assembly 8 through the second flexible shaft pull wire 112. With the synchronous control of a single power source, the synchronicity of the locking action on both sides is ensured. Compared with the independent drive on one side, it can improve the response speed and reliability of the locking mechanism, avoid the risk of single-side locking failure, and enhance the safety of equipment use.

[0031] refer to Figure 2 and Figure 5 The left drive assembly 3 includes a slider 31, a first connecting rod 32 and a second connecting rod 33. The slider 31 is fixedly connected to the first connecting rod 32, the first connecting rod 32 is connected to the second connecting rod 33 in a transmission manner, and the second connecting rod 33 is used in conjunction with the screen back shell assembly 5.

[0032] In this embodiment, the power of the flexible shaft cable is converted into the rotational motion of the screen module through the transmission structure of the left-side drive component 3 via the slider 31, the first connecting rod 32, and the second connecting rod 33. The fixed and transmission connection design of the connecting rod and the slider ensures the stability and efficiency of power transmission, making the rotation of the screen module smoother, reducing vibration and noise during operation, and improving the user experience.

[0033] refer to Figure 5 and Figure 6 The screen module drive and electronic lock assembly 9 includes a motor and a gear set. The gear set has a speed reduction and torque increase function. The motor drives the gear set to release the locking state of the locking tongue structure 71 on both sides and drive the slider 31 to slide through the first flexible shaft pull cable 111 and the second flexible shaft pull cable 112 respectively.

[0034] In this embodiment, the motor and gear set of the screen module drive and electronic lock component 9 work together to provide sufficient power to the first flexible shaft pull cable 111 and the second flexible shaft pull cable 112 through the speed reduction and torque increase function, so as to achieve precise control of the release of the lock tongue structure 71 and the drive of the slider 31. While ensuring power output, the motor load is reduced and the service life of the equipment is extended. Moreover, the method of synchronously driving the dual-side mechanism with a single power source simplifies the overall structure and improves the driving efficiency.

[0035] refer to Figure 9 , Figure 10 and Figure 11 The left drive component 3 and the right drive component 4 have the same maximum rotation angle, and the left drive component 3 and the right drive component 4 are set to rotate synchronously.

[0036] In this embodiment, the left drive component 3 and the right drive component 4 have the same maximum rotation angle and rotate synchronously. This satisfies the viewing angle requirements after the screen is opened (such as for passenger viewing or operation), and the synchronous action ensures that the screen module is subjected to uniform force, avoiding structural deformation or damage caused by excessive force on one side, extending the service life of the equipment, and improving operational safety.

[0037] refer to Figure 5 The top of the fixed base plate assembly 1 is provided with an installation positioning structure and mounting points corresponding to the vehicle body.

[0038] This embodiment uses a fixed base plate assembly 1 with a mounting positioning structure and mounting points corresponding to the vehicle body to enable the device to be quickly and accurately adapted and installed on the roof structure of vehicles such as automobiles, high-speed trains, and airplanes. This simplifies the assembly process between the device and the vehicle body, ensures the stability after installation, improves the versatility and adaptability of the device, and facilitates its application on different types of vehicles.

[0039] When using this vehicle roof dual-sided drive screen assembly, the display screen assembly 6 is initially in a retracted and closed state, and the locking tongue structures 71 of the left lock assembly 7 and the right lock assembly 8 are locked, fixing the screen module below the fixed base plate assembly 1. The protective cover assembly 13 covers the bottom of the device, ensuring overall concealment and aesthetics. When the display screen assembly 6 is opened, the motors of the screen module drive and electronic lock assembly 9 are started. After the motor drive gear set is speed-reduced and torque-increasing, the generated power is transmitted through the first flexible shaft pull cable 111 and the second flexible shaft pull cable 112 in the pull cable assembly 11 to the left drive assembly 3, the right drive assembly 4, the left lock assembly 7, and the right lock assembly 8, respectively. The second flexible shaft pull cable 112 drives the locking tongue structures 71 of the left lock assembly 7 and the right lock assembly 8 to move synchronously, realizing the synchronous unlocking of the screen module before opening. Then, the first flexible shaft pull cable 111 drives... The slider 31 in the left drive assembly 3 and the right drive assembly 4 slides, and the slider 31 drives the second link 33 to move through the first link 32, which in turn transmits the power to the screen back shell assembly 5, causing the display assembly 6 to rotate synchronously on both sides to the maximum opening angle, thus completing the opening. When the display assembly 6 is closed, the motor of the screen module drive and electronic lock assembly 9 rotates in the opposite direction, and drives the slider 31, the first link 32 and the second link 33 to reverse the transmission through the first flexible shaft pull cable 111, so that the screen module rotates synchronously and retracts. When the screen module returns to the closed position, the motor drives the locking tongue structure 71 to reset through the second flexible shaft pull cable 112, and relocks the screen module to complete the closing. Throughout the process, the PCBA assembly 10 realizes the circuit connection and signal transmission of each component through the wiring harness assembly 12, coordinates the motor drive, locking status detection and other actions, and ensures that the whole process is automated and precise.
