DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figures 1 to 12 The embodiment of the utility model provides a transmission device for the movement of a roof screen, including a guide rail 7, a connecting rod movement mechanism 2, and a driving locking mechanism 1 for driving the connecting rod movement mechanism 2 to move and locking the position of the connecting rod movement mechanism 2. The driving locking mechanism 1 is slidably arranged on the guide rail 7. The connecting rod movement mechanism 2 has a rotating assembly that can be driven to rotate when the driving locking mechanism 1 slides. The rotating assembly is provided with a mounting point 19 for the display screen 22 to be installed. The guide rail 7 has a starting position and an end position for the movement of the driving locking mechanism 1. In this embodiment, the driving force of the moving screen is reduced by the connecting rod movement mechanism 2, so that the number of motors used or the use of motors with smaller torque can also achieve a smooth driving effect, reducing the cost. In addition, the driving locking mechanism 1 can lock the screen when the moving screen is closed, and even with a single motor with small torque, it can achieve a safer and more stable effect. Specifically, the transmission device is mainly composed of a connecting rod movement mechanism 2 and a driving locking mechanism 1. The guide rail 7 can be installed on the roof of the car. The installation direction of the guide rail 7 can be limited according to the position of the screen opening. Usually, the guide rail 7 extends along the length of the car. The connecting rod movement mechanism 2 and the driving locking mechanism 1 are both installed according to the guide rail 7. The driving locking mechanism 1 can slide on the guide rail 7 driven by the motor. During the sliding process, the connecting rod movement mechanism 2 will move. The driving locking mechanism 1 moves along the length direction of the guide rail 7, starting from the starting position and stopping at the ending position. When in the starting position, the display screen 22 is as shown in FIG. Figure 5 As shown, it is closed. When it reaches the end position, the rotating assembly can flip the display screen 22 to Figure 6 The state shown, of course, the flip angle of the display screen 22 can be selected as needed. Preferably, a mounting point 19 is designed on the rotating assembly for the display screen 22 to be fixedly mounted, and there can be multiple mounting points 19, such as in the form of lugs.

[0031] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 , the rotating assembly includes a screen mounting bracket 14, a sliding bracket 15 and a rotating connecting rod 16, the mounting point 19 is set on the screen mounting bracket 14, a fixed bracket 17 is installed on the guide rail 7, one end of the rotating connecting rod 16 is hinged on the fixed bracket 17, and the other end of the rotating connecting rod 16 is hinged on the sliding bracket 15, and the screen mounting bracket 14 and the sliding bracket 15 are both hinged on the driving locking mechanism 1. In this embodiment, the above-mentioned rotating assembly is refined, which is mainly composed of a screen mounting bracket 14, a sliding bracket 15 and a rotating connecting rod 16, and the three can rotate, thereby turning over with the display screen 22. Among them, the screen mounting bracket 14 has the above-mentioned mounting point 19 to facilitate the installation of the display screen 22, and a fixed bracket 17 is installed on the guide rail 7. The position of the fixed bracket 17 remains unchanged. When one end of the rotating connecting rod 16 is hinged thereto, when the rotating connecting rod 16 is subjected to force, the rotating connecting rod 16 will rotate. The screen mounting bracket 14 and the sliding bracket 15 are both hinged on the driving locking mechanism 1, specifically on the first driving slider 3. When the driving locking mechanism 1 moves, the screen mounting bracket 14, the sliding bracket 15 and the rotating connecting rod 16 can move together. When the screen mounting bracket 14, the sliding bracket 15 and the rotating connecting rod 16 are blocked at the end position, they can rotate because they are hinged, thereby stably driving the display screen 22 to flip.

[0032] To further optimize the above solution, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Fig.10 , Fig.11 and Fig.12 The screen mounting bracket 14 is provided with a second slide groove 18, and the sliding bracket 15 is provided with a third slide foot 21 that can slide in the second slide groove 18. In this embodiment, the second slide groove 18 and the third slide foot 21 are designed to limit the sliding stroke.

[0033] As an optimization solution of the embodiment of the utility model, please refer to Figure 3 , Figure 4, Figure 7 , Figure 8 and Fig. 9 , the device also includes a locking limit block 11 for locking the starting position of the driving locking mechanism 1 and a blocking limit block 12 for limiting the moving stroke of the driving locking mechanism 1, the locking limit block 11 is located at the starting position, and the blocking limit block 12 is located at the end position. In this embodiment, the locking limit block 11 and the blocking limit block 12 can be designed to cooperate with the movement of the driving locking mechanism 1, and the locking limit block 11 can realize the locking of the driving locking mechanism 1. Only when the unlocking is completed here can it continue to move to the driving connecting rod motion mechanism 2. When the driving locking mechanism 1 moves to the blocking limit block 12, it will be blocked, which is the end stroke. After being blocked, the above-mentioned rotating assembly can complete the rotation under the action of the hinge. The locking limit block 11 and the blocking limit block 12 are both arranged on the guide rail 7 at intervals. The locking limit block 11 and the blocking limit block 12 can be arranged based on the guide rail 7, which can make the structure more compact.

[0034] As an optimization solution of the embodiment of the utility model, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 8 , Fig. 9 , Fig.11 and Fig.12 , the driving locking mechanism 1 includes a screen locking slider 6 that can slide on the guide rail 7, and the screen locking slider 6 is provided with a locking slide groove 13 that can be disengaged from the connecting rod motion mechanism 2. In this embodiment, the connecting rod motion structure is unlocked, so that the locking slide on the screen locking slider 6 is disengaged from the connecting rod motion mechanism 2, specifically, from the bracket locking slider 20 on the screen mounting bracket 14, thereby unlocking the connecting rod motion mechanism 2, and before that, the display screen 22 will be stably locked under this structure.

[0035] To further optimize the above solution, please refer to Figures 1 to 12The driving locking mechanism 1 further comprises a first driving slider 3, a locking link 4 and a second driving slider 5 which can drive the locking link 4 to move. The first driving slider 3 and the second driving slider 5 are both slidably arranged on the guide rail 7. The first driving slider 3 is hinged to the locking link 4, and the second driving slider 5 is hinged to the screen locking slider 6. The locking link 4 is provided with a first sliding foot 10 which can be disengaged from the starting position. In this embodiment, the second driving slider 5 obtains power from the motor to slide on the guide rail 7, and the two slide along the length direction of the guide rail 7. After the first driving slider 3 and the locking link 4 are hinged, they will move simultaneously, and their driving force is the driving force when the second sliding foot 8 on the second driving slider 5 moves forward and backward in the first slide groove 9 to the top. During the sliding process, since the first driving slider 3 is hinged to the locking link 4, and the second driving slider 5 is hinged to the screen locking slider 6, when unlocking, the second slide foot 8 moves in the first slide groove 9 to the rear end stop of the first slide groove 9, and the locking link 4 will rotate along the hinge point with the first driving slider 3 (the rotation range is determined by the L-shaped shape of the first slide groove 9, and it needs to cooperate with the L-shaped slide groove on the locking limit block 11), and the first slide foot 10 on the locking link 4 will be disengaged from the starting position, thereby realizing the unlocking of the drive system. At this time, the second slide foot 8 will continue to move backward, pulling the first slide groove 9 backward, so that the second driving slider 5 can move backward with the first driving slider 3, specifically, the first slide foot 10 slides out of the locking limit block 11, as shown in FIG. Figure 8 and Fig. 9 As shown, an L-shaped slide groove is designed on the locking limit block 11. Preferably, the first driving slider 3 is connected to the locking connecting rod 4 by a pin.

[0036] To further optimize the above solution, please refer to Figure 8 and Fig. 9 , the locking link 4 is provided with a first slide groove 9, the first slide groove 9 extends along the length direction of the guide rail 7, and the second driving slider 5 is provided with a second slide foot 8 that can slide in the first slide groove 9. In this embodiment, the first slide groove 9 is designed on the locking link 4, which can facilitate limiting the sliding direction of the second driving slider 5, thereby completing the precise unlocking at the locking limit block 11. Specifically, the second driving slider 5 slides in the first slide groove 9 in the locking link 4 through the second slide foot 8, thereby driving the first slide foot 10 on the locking link 4 to disengage from the locking limit block 11 of the guide rail 7, as shown in FIG. Figure 8 As shown. When the second driving slider 5 slides, it drives the screen locking slider 6 through the pin, so that the locking slide groove 13 on the screen locking slider 6 is disengaged from the bracket locking slider 20 on the screen mounting bracket 14, thereby unlocking the connecting rod movement mechanism 2. When the first sliding foot 10 on the locking connecting rod 4 hits the blocking limit block 12 on the guide rail 7, the connecting rod movement mechanism 2 reaches the open state, and the display screen 22 will be flipped open.

[0037] See also Figures 1 to 12 In combination with the above embodiment, the specific flipping principle of the display screen 22 is as follows: after the bracket locking slider 20 on the screen mounting bracket 14 is unlocked, the first driving slider 3 is driven by the second driving slider 5, so that the screen mounting bracket 14 is driven by the first driving slider 3, the fixed bracket 17 is fixed on the guide rail 7, so that the rotating link 16 can only rotate along the pin of the fixed bracket 17, the sliding bracket 15 and the first driving slider 3 are connected by the pin to rotate, and the third sliding foot 21 on the sliding bracket 15 slides along the second slide groove 18 on the screen mounting bracket 14 when the screen mounting bracket 14 moves. The end of the sliding bracket 15 is connected to the rotating link 16 so that its movement trajectory can only move according to the movement trajectory of the rotating link 16, so that the screen mounting bracket 14 can achieve flipping movement. During the closing process, the third sliding foot 21 on the sliding bracket 15 continuously changes the force arm ratio when sliding in the second slide groove 18 to reduce the operating driving force of the second driving slider 5, thereby solving the problem of insufficient driving force of a single motor.

[0038] See also Figures 1 to 12 The embodiment of the utility model provides a roof display screen system, including a display screen 22 and the above-mentioned transmission device for the movement of the roof screen, the guide rails 7 are provided in two pieces, the two guide rails 7 are arranged in parallel and spaced apart, the connecting rod movement mechanism 2 and the driving locking mechanism 1 are provided in two sets, each set of the connecting rod movement mechanism 2 and the driving locking mechanism 1 is installed on one of the guide rails 7, and the opposite sides of the display screen 22 are respectively installed on the two sets of the connecting rod movement mechanism 2. In this embodiment, the above-mentioned transmission device can be used for the automatic opening and closing of the display screen 22, and the driving force of the moving screen is reduced by the connecting rod movement mechanism 2, so that the number of motors used is reduced or a motor with a smaller torque can also achieve a stable driving effect, reducing the cost, and the driving locking mechanism 1 can lock the screen when the moving screen is closed, even with a single motor with a small torque, it can achieve a safer and more stable effect. When the system is used in a car, the two guide rails 7 can be arranged in parallel and spaced apart on the roof of the car, so that the closing or opening of the display screen 22 can be stably driven.
