Description

Technical Field

[0001] This utility model relates to the field of vehicle electronic product technology, and in particular to an anti-pinch vehicle display. Background Technology

[0002] In-vehicle displays are being used more and more widely in some family cars or commercial vehicles. In-vehicle displays allow passengers to watch videos, enhancing their enjoyment of the car ride.

[0003] Existing in-vehicle displays typically include a base and a display screen mounted on the base. The base is fixed inside the vehicle, while the display screen can be flipped up and down by a drive mechanism. The base has a storage recess that matches the display screen. When needed, the display screen flips up to the open position, allowing passengers to view it. After use, the display screen can be flipped back into the storage recess on the base to achieve a stowage state, thus reducing the space occupied inside the vehicle.

[0004] However, during the use of existing in-vehicle displays, accidents involving fingers being pinched by the display screen occur frequently when the screen is flipped into the storage recess. The reason for this is that when the display screen is flipped, the occupant places their fingers on the edge of the storage recess, and the existing in-vehicle displays cannot detect the presence of fingers, resulting in the occupant's fingers being pinched when the screen is flipped into the storage recess, posing a certain safety hazard during use. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies and provide an anti-pinch vehicle display.

[0006] The purpose of this utility model is achieved through the following technical solution: an anti-pinch vehicle display, including a base, a display screen, a drive device for driving the display screen to rotate, and a control system. The base is provided with a storage groove for storing the display screen. Photoelectric sensing components are respectively provided at the four corners of the storage groove. Each photoelectric sensing component includes a photoelectric transmitter and a photoelectric receiver. The photoelectric transmitter and the photoelectric receiver are electrically connected to the control device. The photoelectric transmitter in any photoelectric sensing component and the photoelectric receiver in the adjacent photoelectric sensing component form a photoelectric beam-beaming mechanism. A sensing area is formed between the photoelectric beam-beaming mechanisms. When an external object enters the sensing area, the control system controls the drive device to stop running.

[0007] Preferably, the photoelectric sensing component further includes a cover, which is installed above the photoelectric transmitter and the photoelectric receiver. Each cover has two photoelectric windows, and the photoelectric transmitter and the photoelectric receiver are respectively located in the two photoelectric windows on the cover.

[0008] Preferably, the cover is L-shaped and is connected to the base by screws.

[0009] Preferably, a decorative cover is also included, the device cover is connected to the base, and the protective cover is clamped between the device cover and the base.

[0010] Preferably, the decorative cover plate is provided with a number of fasteners, and the base is provided with slots corresponding to the fasteners, so that the fasteners on the decorative cover plate can be engaged into the slots on the base.

[0011] Preferably, the photoelectric transmitter is an infrared transmitter and the photoelectric receiver is an infrared receiver.

[0012] Preferably, the photoelectric transmitter is a laser transmitter and the photoelectric receiver is a laser receiver.

[0013] The beneficial effects of this utility model are: 1. In this utility model, when the display screen is flipped to the storage state, the driving device can be stopped immediately after a finger enters the sensing area, thereby effectively preventing the passenger's finger from being pinched, realizing the anti-pinch function, avoiding injury to the passenger, and reducing the safety hazards when using the vehicle display.

[0014] 2. This utility model has sensitive and timely detection. The infrared beam mechanism can quickly detect objects after they enter the sensing area without the object having direct contact with the ceiling screen. Compared with the traditional mechanical contact anti-pinch solution, it can provide early warning and take anti-pinch measures, which greatly improves the timeliness and effectiveness of anti-pinch.

[0015] 3. High reliability: The infrared beam-beaming mechanism has a relatively simple structure, is less affected by environmental factors, has stable performance, and is not prone to aging or failure. It can work reliably for a long time, ensuring the stability of the anti-pinch function of the display screen.

[0016] 4. This utility model has strong applicability: This structure is applicable to various types of vehicle displays. It does not require large-scale modification of the original structure of the vehicle display. It can achieve the anti-pinch function simply by installing infrared beam mechanisms on its four edges and connecting them to the control unit, which greatly facilitates the promotion and application of this technology.

[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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0026] like Figures 1 to 7 As shown, an anti-pinch vehicle-mounted display includes a base 3, a display screen 2, a drive device 4 for driving the display screen 2 to rotate, and a control system, with the control system housed in the base. The base 3 has a storage groove 6 for housing the display screen 2; photoelectric sensing components are respectively installed at the four corners of the storage groove 6. Each photoelectric sensing component includes a photoelectric transmitter 9 and a photoelectric receiver 10, both of which are electrically connected to the control device. The photoelectric transmitter 9 in any one photoelectric sensing component and the photoelectric receiver 10 in an adjacent photoelectric sensing component form a photoelectric beam-through mechanism, creating a sensing area between the photoelectric beam-through mechanisms. When an external object enters the sensing area, the control system controls the drive device 4 to stop operating.

[0027] In this invention, the display screen 2 is driven to flip by the drive device 4 to open or retract. When the display screen 2 is in the retracted state, it enters the retractable groove 6. The retractable groove 6 is rectangular, and a photoelectric sensing component is set at each of the four corners of the retractable groove 6. A photoelectric beam-beaming mechanism is formed by the photoelectric transmitter 9 and photoelectric receiver 10 in two adjacent photoelectric sensing components, and a sensing area is formed at the edge of the retractable groove 6 through the photoelectric beam-beaming mechanism. During the process of the display screen 2 flipping to the retracted state, when a passenger's finger enters the sensing area, the photoelectric beam-beaming mechanism is blocked by the finger, thereby triggering the photoelectric beam-beaming mechanism and generating a trigger signal. The trigger signal is transmitted to the control system in the vehicle display, and the control system immediately controls the drive device 4 to stop running, so that the display screen 2 stops flipping. After the finger leaves the sensing area, the display screen 2 continues to flip until it reaches the retracted state. In this invention, when the display screen 2 is flipped to the storage state, the drive device 4 can be stopped immediately after a finger enters the sensing area, thereby effectively preventing the passenger's finger from being pinched, realizing the anti-pinch function, avoiding injury to the passenger, and reducing the safety hazards when using the vehicle display.

[0028] While some existing vehicle displays have overcurrent detection and anti-pinch functions, when the display is flipped close to the storage recess, the current change is not significant when there is an obstacle blocking the movement of the display's flipping arm, thus failing to prevent pinching injuries. Other vehicle displays have added touchscreen anti-pinch features, but because the pinching point is not within the touchscreen's range, they cannot prevent fingers from being pinched when inserted into the edge of the storage recess. This invention, however, achieves a more thorough anti-pinch effect by incorporating a photoelectric beam mechanism.

[0029] The photoelectric sensing component also includes a cover 5, which covers the photoelectric transmitter 9 and the photoelectric receiver 10. Each cover 5 has two photoelectric windows 11, and the photoelectric transmitter 9 and the photoelectric receiver 10 are respectively located in the two photoelectric windows 11 on the cover 5. The cover 5 protects the photoelectric transmitter 9 and the photoelectric receiver 10 from external impacts, thereby improving the stability and reliability of the photoelectric sensing component and extending its service life. Furthermore, the photoelectric windows 11 on the cover 5 act as light shields, reducing interference from stray light and allowing the light emitted by the photoelectric transmitter 9 to be more concentrated on the photoelectric receiver 10, improving the accuracy and sensitivity of the photoelectric sensing. Both the photoelectric transmitter 9 and the photoelectric receiver 10 are mounted on an L-shaped circuit board 8.

[0030] In this embodiment, the cover 5 is L-shaped and is connected to the base 3 by screws.

[0031] This utility model also includes a decorative cover plate 1, which is connected to the base 3, and a protective cover 5 is sandwiched between the device cover plate and the base 3. The decorative cover plate 1 is set on the base 3, which serves a decorative purpose and improves the aesthetics of the vehicle display; on the other hand, the protective cover 5 is sandwiched between the device cover plate and the base 3, and the pressure applied to the protective cover 5 by the decorative cover plate 1 can improve the stability of the installation of the protective cover 5.

[0032] The decorative cover plate 1 is provided with several fasteners 12, and the base 3 is provided with slots 7 corresponding to the fasteners 12. The fasteners 12 on the decorative cover plate 1 are engaged in the slots 7 on the base 3. The decorative cover plate 1 is connected to the base 3 by a fastener connection, which facilitates the assembly of the decorative cover plate 1.

[0033] In some embodiments of this application, the photoelectric transmitter 9 is an infrared transmitter, and the photoelectric receiver 10 is an infrared receiver. The infrared light generated by the infrared transmitter is received by the infrared receiver in an adjacent photoelectric sensing component, thereby forming a sensing area between the infrared transmitter and the infrared receiver.

[0034] In some other embodiments of this application, the photoelectric transmitter 9 is a laser transmitter, and the photoelectric receiver 10 is a laser receiver. The laser light generated by the laser transmitter is received by the laser receiver in an adjacent photoelectric sensing component, thereby forming a sensing area between the laser transmitter and the laser receiver.

[0035] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
