Description

Technical Field

[0001] This utility model relates to the field of vehicle display screens, and more specifically, to a vehicle-mounted flip screen with anti-pinch function. Background Technology

[0002] As an important component of modern automotive smart cockpits, in-vehicle rotating screens typically achieve a balance between display functionality and space optimization through flipping and unfolding or folding for storage. In existing technologies, the anti-pinch function of such rotating screens mainly relies on monitoring the screen's rotational torque: when the screen encounters a foreign object (such as a user's finger) during rotation, the system triggers a stop by detecting an abnormal increase in the drive motor's load torque. However, this anti-pinch action only triggers after the screen and the foreign object have made physical contact and generated sufficient resistance. At this point, the user is already at risk of injury. Furthermore, due to the inertia and damping of the mechanical transmission system, the system needs to reach a high threshold to detect an anomaly, leading to failure in protection against small objects or low-resistance gripping scenarios. Utility Model Content

[0003] The purpose of this invention is to provide a vehicle-mounted flip screen with anti-pinch function, which can realize non-contact detection of foreign objects, eliminate the lag of traditional anti-pinch systems, and actively prevent pinching before physical contact.

[0004] A vehicle-mounted flip screen with anti-pinch function includes a mounting base and a display screen. The display screen is rotatably connected to the mounting base and is configured to rotate to unfold or fold. The mounting base includes a panel with a receiving slot for accommodating the display screen. A plurality of sensing components for sensing foreign objects are arranged around the periphery of the receiving slot on the panel.

[0005] In the aforementioned technical solution, sensing components are arranged in a ring around the panel receiving slot, thus forming comprehensive anti-pinch sensing along the display's folding path. When a foreign object approaches the gap area, the system can proactively identify the risk before physical contact occurs. Compared to traditional torque detection solutions, this design innovatively advances the anti-pinch trigger point from the mechanical force stage to the spatial approach stage, eliminating response lag. Simultaneously, the ring layout conforms to the receiving trajectory of the flip screen, enabling synchronous response to foreign object intrusion from any angle. This embedded protective structure improves the reliability of the anti-pinch structure without altering the panel's appearance, thereby enhancing the display's safety.

[0006] Furthermore, the sensing component includes a sensor, the panel has a through hole, and the sensor is disposed opposite to the through hole.

[0007] In the above technical solution, the through hole is positioned opposite to the sensor to ensure that the sensor signal can directly penetrate the panel surface and avoid signal attenuation.

[0008] Furthermore, the sensing component also includes a light-transmitting element, which is embedded in the through hole.

[0009] In the above technical solution, the light-transmitting element is embedded in the through hole, which can protect the sensor while ensuring the sensing sensitivity, and also play a sealing role to prevent the sensor from being invaded by dust.

[0010] Furthermore, the surface of the light-transmitting element is flush with the surface of the panel.

[0011] In the above technical solution, the design of the light-transmitting component surface being flush with the panel eliminates steps or gaps, preventing dust accumulation or damage from bumps due to height differences, while maintaining the smooth and streamlined appearance of the panel, which meets the aesthetic requirements of vehicle interiors.

[0012] Furthermore, the sensor is a distance sensor.

[0013] In the above technical solution, a distance sensor is used to achieve non-contact sensing, which can ensure sensitivity and accuracy.

[0014] Furthermore, the display screen includes a hinge, and the receiving groove includes a first side near the hinge, a second side opposite to the first side, and a third side and a fourth side connecting the first side and the second side, with the sensing component disposed near the second side, the third side and the fourth side.

[0015] In the above technical solution, the sensing components are arranged along the second, third, and fourth sides, which can provide protection for high-risk gap areas on the non-rotating shaft side.

[0016] Furthermore, the mounting base is provided with a drive assembly for driving the display screen to rotate.

[0017] In the above technical solution, the drive component is built into the mounting base, reducing exposed transmission parts, lowering the risk of interference, and enabling the display screen to flip.

[0018] Furthermore, the sensing component is electrically connected to the driving component.

[0019] In the above technical solution, the sensing component and the driving component are electrically directly connected, and the driving component can be controlled to operate through sensing signals, thereby improving the response speed.

[0020] Compared with existing technologies, the advantages of this invention are as follows: A ring-shaped arrangement of sensing components around the panel receiving groove creates a seamless anti-pinch sensor along the display's folding path. When a foreign object approaches the gap area, the system can proactively identify the risk before physical contact occurs. Compared to traditional torque detection schemes, this design innovatively advances the anti-pinch trigger point from the mechanical force stage to the spatial approach stage, eliminating response lag. Simultaneously, the ring-shaped layout conforms to the receiving trajectory of the flip screen, enabling synchronous response to foreign object intrusion from any angle. This embedded protective structure improves the reliability of the anti-pinch structure without altering the panel's appearance, thereby enhancing the display's safety. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0028] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0029] Please refer to Figures 1 to 4 In a preferred embodiment, the vehicle-mounted flip screen with anti-pinch function of the present invention mainly includes a mounting base 1 and a display screen 2. The display screen 2 is rotatably connected to the mounting base 1. The display screen 2 is configured to be able to rotate to unfold or fold. The mounting base 1 includes a panel 11. The panel 11 is provided with a receiving groove 112 for accommodating the display screen 2. A plurality of sensing components 3 for sensing foreign objects are arranged around the periphery of the panel 11 near the receiving groove 112.

[0030] For example, mounting base 1 provides a mounting foundation for display screen 2. In specific implementations, mounting base 1 can be located inside a motor vehicle, such as on the roof, center console, or behind the seats. Display screen 2 can rotate relative to mounting base 1, thereby exposing or folding the screen. Display screen 2 can be any existing display device.

[0031] Sensing components 3 are arranged in a ring around the receiving groove 112 of panel 11, thus forming a comprehensive anti-pinch sensing along the folding path of display screen 2. When a foreign object approaches the gap area, the system can proactively identify the risk before physical contact occurs. Compared with traditional torque detection schemes, this design innovatively advances the anti-pinch trigger point from the mechanical force stage to the spatial approach stage, eliminating response lag. At the same time, the ring layout conforms to the receiving trajectory of the flip screen, enabling synchronous response to foreign object intrusion from any angle. This embedded protective structure improves the reliability of the anti-pinch structure without changing the appearance of panel 11, thereby enhancing the safety of display screen 2.

[0032] The sensing component 3 includes a sensor 31, and the panel 11 has a through hole 111. The sensor 31 is disposed opposite to the through hole 111. For example, the sensor 31 can be an existing distance sensor 31, thereby achieving non-contact sensing and ensuring sensitivity and accuracy. The through hole 111 is disposed opposite to the sensor 31 to ensure that the sensor 31 signal directly penetrates the surface of the panel 11, avoiding signal attenuation.

[0033] In this embodiment, the sensing component 3 further includes a light-transmitting element 32, which is embedded in the through hole 111. The light-transmitting element 32 can be a colored or transparent lens. The light-transmitting element 32 is embedded in the through hole 111, which can protect the sensor 31 while ensuring the sensing sensitivity, and also play a sealing role to prevent the sensor 31 from being invaded by dust.

[0034] In this embodiment, the surface of the light-transmitting element 32 is flush with the surface of the panel 11. The design that the surface of the light-transmitting element 32 is flush with the surface of the panel 11 eliminates steps or gaps, prevents dust accumulation or damage from bumps due to height differences, and maintains the smooth and streamlined appearance of the panel 11, which meets the aesthetic requirements of automotive interiors.

[0035] The display screen 2 includes a hinge 21, and the receiving groove 112 includes a first side 113 near the hinge 21, a second side 114 opposite to the first side 113, and a third side 115 and a fourth side 116 connecting the first side 113 and the second side 114. The sensing component 3 is disposed near the second side 114, the third side 115, and the fourth side 116. The sensing component 3 is disposed along the second, third, and fourth sides, and can provide protection for high-risk gap areas on the side not connected to the hinge 21.

[0036] Mounting base 1 contains a drive assembly for rotating the display screen 2. The drive assembly can be any existing type, such as a motor-driven rotation module, to rotate the display screen 2; its specific structure will not be described in detail here. The drive assembly is built into mounting base 1, reducing exposed transmission components, lowering the risk of interference, and simultaneously enabling the display screen 2 to rotate.

[0037] In this embodiment, the sensing component 3 is electrically connected to the driving component. This direct electrical connection allows the driving component to be controlled via a sensing signal, improving response speed. It is understood that in some possible embodiments, the mounting base 1 contains a control board, to which both the sensing component 3 and the driving component are electrically connected. Upon receiving a sensing signal from the sensing component 3, the control board controls the start and stop of the driving component. Existing control circuitry can be used for the control board, and will not be elaborated upon here.
