Description

Technical Field

[0001] This invention relates to the field of automotive parts technology, specifically to a vehicle-mounted ceiling-mounted screen device and a vehicle. Background Technology

[0002] In recent years, with the upgrading of the smart cockpit experience, some car models have installed flip-up ceiling-mounted screens in the front row to provide passengers with entertainment and information interaction. In some applications, the anti-pinch mechanism of the in-vehicle ceiling-mounted screen mainly relies on electronic sensing: when the DC acceleration motor drives the screen to close, the motor load is monitored in real time through Hall sensors or current sampling circuits. When a sudden current change or an obstacle is detected, the control module immediately cuts off the motor power to achieve anti-pinch protection. However, this electronic solution has some shortcomings: firstly, the system is highly sensitive to sensor accuracy and control algorithms. Once the sensor fails, the software misjudges, or is subjected to electromagnetic interference, the anti-pinch function will fail, especially posing a high risk of pinching injury to active children; secondly, electronic anti-pinch requires additional sensors, wiring harnesses, and redundant control logic, resulting in complex structure and increased material and calibration costs, which is not conducive to large-scale adoption.

[0003] Therefore, this application studies a vehicle-mounted ceiling screen that uses a physical structure to prevent hand pinching, which is more reliable and has a simpler structure, thus better meeting the needs for preventing hand pinching. Summary of the Invention

[0004] To achieve the anti-pinch function through physical structure, it is more reliable and simple in structure, and better meets the anti-pinch needs.

[0005] On the one hand, the vehicle-mounted ceiling-mounted screen device provided in this application adopts the following technical solution:

[0006] A vehicle-mounted ceiling-mounted screen device includes a screen body and a flip-up drive mechanism. The screen body is connected to a screen hinge. The flip-up drive mechanism includes an elastic energy storage component, a drive component, and a fixed frame. The elastic energy storage component and the drive component are both mounted on the fixed frame. A first end of the elastic energy storage component is rotatably connected to the fixed frame, and a second end is rotatably connected to the screen hinge. The elastic energy storage component provides an active force when the screen body is closed and stops extending when the resistance reaches a threshold. The output end of the drive component is connected to the screen hinge and is used to overcome the elastic force of the elastic energy storage component and compress the elastic energy storage component when the screen body is flipped open.

[0007] By adopting the above technical solution, the driving component drives the screen hinge to rotate and open the screen body. When the screen body is closed, the elastic energy storage component provides a limited active force during the closing process. When the screen body is subjected to external resistance during the closing process and the resistance is greater than the set threshold of the elastic energy storage component, the elastic energy storage component automatically stops extending, keeping the screen in the current position, thereby achieving physical anti-pinch protection. This solves the risk of electronic anti-pinch failure, is more reliable and has a simpler structure, and better meets the anti-pinch requirements.

[0008] Optionally, the output end of the drive unit is connected to a coupling, which is connected to the screen shaft.

[0009] By adopting the above technical solution, a detachable and flexible connection between the drive component and the screen hinge is achieved using a coupling, which not only ensures the accuracy of torque transmission but also reduces the difficulty of assembly and maintenance, solving the defects of traditional rigid connections that are prone to wear and have high assembly tolerance requirements.

[0010] Optionally, a camshaft is provided at the end of the screen hinge, the camshaft having a boss, the boss being rotatably connected to the first end of the elastic energy storage member.

[0011] By adopting the above technical solution, the camshaft is integrated into the end of the rotating shaft, resulting in a compact structure and smooth transmission.

[0012] Optionally, a rotating rod is connected to the boss, the end of the rotating rod is a ball, the first end of the elastic energy storage member has a ball socket, and the ball is rotatably connected to the ball socket.

[0013] By adopting the above technical solution, the ball-and-socket joint allows the elastic energy storage component to adapt to angle changes during extension and retraction, significantly reducing lateral force and wear, thereby extending component life and improving the sensitivity of anti-pinch action.

[0014] Optionally, the rotating rod is provided with threads and is threadedly connected to the boss.

[0015] By adopting the above technical solution, the initial lever arm of the elastic energy storage component can be quickly and finely adjusted by adjusting the extension length of the rotating rod via the thread, thereby accurately setting the anti-pinch threshold and solving the problem of poor threshold consistency in mass production.

[0016] Optionally, the fixing frame is provided with an adjusting member, one end of which abuts against the second end of the elastic energy storage member, for adjusting the initial expansion and contraction of the elastic energy storage member.

[0017] By adopting the above technical solution, the adjustment component can change the pre-compression amount of the elastic energy storage component without disassembling the assembly, thereby achieving online adjustment of the threshold, meeting the differentiated needs of different models / users for anti-pinch force, and reducing after-sales calibration costs.

[0018] Optionally, the second end of the elastic energy storage element has an adjusting shaft, the adjusting shaft has an adjusting hole, and the adjusting element abuts against the adjusting hole.

[0019] By adopting the above technical solution, stepless fine adjustment can be achieved, avoiding the problem of easy loosening of traditional nut adjustment and improving long-term stability.

[0020] Optionally, the elastic energy storage element is a gas spring.

[0021] By adopting the above technical solution, the gas spring has a smooth output force curve and built-in damping at the end of the stroke, which can provide a gentle buffer at the end of the closing phase, further reducing the impact force of pinching the hand. At the same time, it has a high degree of standardization, low cost, and is conducive to large-scale application.

[0022] On the other hand, the automobile provided in this application adopts the following technical solution:

[0023] An automobile includes a vehicle body and the aforementioned in-vehicle ceiling-mounted screen device, wherein the in-vehicle ceiling-mounted screen device is installed on the inner top of the vehicle body.

[0024] In summary, this application includes the following beneficial technical effects:

[0025] 1. The elastic energy storage component provides a limited active force when closing. When the screen body is subjected to external resistance during the closing process and the resistance is greater than the set threshold of the elastic energy storage component, the elastic energy storage component automatically stops extending, keeping the screen in the current position, thereby achieving physical anti-pinch protection. This solves the risk of electronic anti-pinch failure, is more reliable and has a simpler structure, and better meets the anti-pinch requirements.

[0026] 2. The ball joint allows the elastic energy storage element to adapt to angle changes during extension and retraction, significantly reducing lateral forces and wear, thereby extending the component's lifespan and improving the sensitivity of the anti-pinch action;

[0027] 3. The adjustment component can change the pre-compression amount of the elastic energy storage component without disassembling the assembly, so as to realize the online adjustment of the threshold, meet the different needs of different models / users for anti-pinch force, and reduce after-sales calibration costs.

Detailed Implementation

[0036] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0037] This application discloses a vehicle-mounted ceiling-mounted screen device. (Refer to...) Figures 1-3 The vehicle-mounted ceiling-mounted screen device includes a screen body 14 and a flip-up drive mechanism 13. In this embodiment, a control component 11 is also provided on the screen body 14, and both the screen body 14 and the flip-up drive mechanism 13 are installed within a fixed frame 12. The screen body 14 is connected to a screen pivot 141, which extends along the length of the screen body 14 and extends to both sides. The screen body 14 is rotated by rotating the screen pivot 141. The flip-up drive mechanism 13 includes an elastic energy storage element 135, a drive element, and a fixed frame 131. In some embodiments, the elastic energy storage element 135 is a gas spring. The gas spring has a smooth output force curve and has built-in damping at the end of its stroke, which can provide a gentle buffer at the end of the closing phase, further reducing the impact force of pinching the hand. The drive element adopts a geared motor module 132. The output end of the drive element is connected to the screen pivot 141, which is used to overcome the elastic force of the elastic energy storage element 135 and compress the elastic energy storage element 135 when the screen body 14 is flipped open, thereby driving the screen body 14 to rotate.

[0038] Both the elastic energy storage component 135 and the driving component are mounted on the fixed frame 131. The first end of the elastic energy storage component 135 is rotatably connected to the fixed frame 131. In this embodiment, the first end is the end of the gas spring body. The second end is rotatably connected to the screen pivot 141. In this embodiment, the second end is the end of the gas spring output end. In other embodiments, the directions of the first and second ends can be interchanged. The gas spring is used to provide the active force when the screen body 14 is closed and to stop extending when the resistance reaches a threshold, thereby realizing the physical anti-pinch function, avoiding the insensitive response caused by electronic methods, and better improving the anti-pinch effect.

[0039] In some embodiments, the output end of the drive unit is connected to a coupling 133, which is connected to the screen rotating shaft 141. The output end of the geared motor module 132 is connected to the screen rotating shaft 141 via the coupling 133 to ensure rotational stability and accuracy.

[0040] Reference Figure 2 and Figure 4 In some embodiments, a camshaft 142 is screwed to the end of the screen hinge 141. The main body of the camshaft 142 is in the form of a coupling 133, which is fitted to the output end of the drive component. The camshaft 142 has a boss that is rotatably connected to the first end of the elastic energy storage component 135. This allows for more stable power conversion and eliminates rotational deviation of the elastic energy storage component 135.

[0041] Continue to refer to Figure 2 In some embodiments, a rotating rod 134 is connected to the boss, and the end of the rotating rod 134 is a ball. The first end of the elastic energy storage element 135 has a ball socket, and the ball is rotatably connected to the ball socket. The ball socket-ball joint allows the elastic energy storage element 135 to adapt to angle changes during extension and retraction, significantly reducing lateral forces and wear, thereby extending the life of the element and improving the sensitivity of the anti-pinch action.

[0042] In some embodiments, the rotating rod 134 is threaded and threadedly connected to the boss. This allows the position of the rotating rod 134 to be adjusted for better engagement with the elastic energy storage member 135.

[0043] Reference Figure 2 and Figure 3 In some embodiments, an adjusting member 136 is provided on the fixing frame 131. In this embodiment, the adjusting member 136 is a bolt, which is screwed onto the fixing frame 131. One end of the adjusting member 136 abuts against the second end of the elastic energy storage member 135, and is used to adjust the initial expansion and contraction of the elastic energy storage member 135. By adjusting the position of the bolt, the initial compression of the elastic energy storage member 135 can be adjusted to obtain the corresponding preload, so that it can be adjusted according to actual needs.

[0044] In some embodiments, the second end of the elastic energy storage member 135 has an adjusting shaft 137, one end of which is mounted on the fixing frame 131. The adjusting shaft 137 passes through the elastic energy storage member 135 and has two adjusting holes, located on both sides of the elastic energy storage member 135 and symmetrically arranged about the central axis of the elastic energy storage member 135. Two adjusting members 136 are also provided, each abutting against one of the two adjusting holes. This allows for more stable support and adjustment of the elastic energy storage member 135.

[0045] The implementation principle of the vehicle-mounted ceiling screen device in this application embodiment is as follows: the elastic energy storage component 135 provides a limited active force when closed. When the screen body 14 is subjected to external resistance during the closing process and the resistance is greater than the set threshold of the elastic energy storage component 135, the elastic energy storage component 135 automatically stops extending, so that the screen remains in the current position, thereby realizing physical anti-pinch, which solves the risk of electronic anti-pinch failure, is more reliable and has a simple structure, and better meets the anti-pinch needs.

[0046] This application discloses an automobile. (Refer to...) Figure 5 An automobile includes a vehicle body 2 and the aforementioned in-vehicle ceiling-mounted screen device 1, wherein the in-vehicle ceiling-mounted screen device 1 is installed on the inner top of the vehicle body 2.
