[0040] Reference Figures 1 to 5 The diagram shows a structural schematic of a display screen device according to an embodiment of this application. The display screen device may specifically include: a display module 10 and a housing 20; the housing 20 is connected to the display module 10; the edge of the housing 20 is provided with a mounting position 21, and the mounting position 21 is provided with a magnetic attraction structure, which is used to magnetically attract a camera device.

[0041] In this embodiment, during assembly, the camera device can be magnetically attached to the edge of the housing 20 via the magnetic structure on the mounting position 21. This simple structure offers good connection reliability and simplifies installation, making it convenient to operate without the need for tools to tighten screws, thus reducing cumbersome installation steps. Similarly, the camera device can be easily detached from the display device without the need to loosen screws, further reducing cumbersome disassembly steps and enhancing ease of installation and disassembly, thereby improving the user experience.

[0042] For example, in this embodiment, the edge of the housing 20 may be a position on the frame area of ​​the display module 10 opposite to the housing 20. For example, the display device may be disposed in the space of a mobile device, such as the interior space of a vehicle, such as a vehicle, an airplane, rail transportation (train, high-speed rail, etc.), a ship, etc.

[0043] Specifically, in this embodiment, the display module 10 is used to display images, and the housing 20 covers the part of the display module 10 except for the display surface, for protection. The mounting position 21 is used to mount a camera device. For example, the housing of the camera device can be assembled and connected to the mounting position 21 to capture video images and obtain image information through the camera module.

[0044] For example, in this embodiment, the housing of the camera device may be provided with a magnet corresponding to the magnetic structure. The magnet and the magnetic structure are magnetically attracted, resulting in better connection stability and reliability. Furthermore, the position on the housing of the camera device opposite the magnetic structure can also be made of a magnetically attractive material, such as iron, cobalt, nickel, or stainless steel, etc. This embodiment does not impose any limitations on this.

[0045] Optionally, in this embodiment, the magnetic structure includes a magnetic element 30 connected to the mounting position 21. The magnetic element 30 is used to magnetically attract the camera device. For example, the magnetic element 30 can be a magnetic material or a magnetic sheet, etc., thus providing a relatively stable and reliable magnetic attraction force. For example, a mounting groove can be provided on the mounting position 21, and the magnetic element 30 can be assembled into the mounting groove. Furthermore, an adhesive can be provided on the groove wall to bond the magnetic element 30 to the groove wall, etc. The specific method by which the magnetic element 30 is connected to the mounting position 21 is not limited in this embodiment.

[0046] For example, in the embodiments of this application, the magnetic component 30 can be a ferromagnetic component, such as a samarium cobalt magnet, a neodymium iron boron magnet, or an iron oxide magnet, etc., which is low in cost, widely used, and easy to implement.

[0047] In this embodiment, optionally, the magnetic attraction structure includes a first magnetic element 31 and a second magnetic element 32, which are spaced apart at both ends of the mounting position 21. This provides magnetic connection points at both ends of the mounting position 21 via the first magnetic element 31 and the second magnetic element 32, further improving the connection stability and reliability of the camera device. For example, the first magnetic element 31 and the second magnetic element 32 can be symmetrically distributed, resulting in better uniform force distribution during camera device assembly.

[0048] For example, in the embodiments of this application, the shape of the first magnetic element 31 and the second magnetic element 32 can be a cuboid, a cube, or a disc, etc., which can be set according to actual needs. The embodiments of this application do not limit the specific shape and size of the first magnetic element 31 and the second magnetic element 32.

[0049] Optionally, in this embodiment, the mounting position 21 has an opening 22, and a snap-fit ​​platform 23 is provided within the opening 22 for snapping the camera device. Specifically, the camera device may have a buckle. When installing the camera device on the display screen device, the buckle can be snapped onto the snap-fit ​​platform 23 within the opening 22, so that the camera device is snapped onto the display screen device. Based on the magnetic adsorption connection, this further improves the reliability and stability of the connection between the display screen device and the camera device. Furthermore, the snap-fit ​​method is simple and convenient, and also has good ease of installation and disassembly.

[0050] In this embodiment, optionally, the number of openings 22 includes two, with the two openings 22 respectively disposed on both sides of the magnetic attraction structure. This allows for a good match between the magnetic attraction structure's magnetic adsorption connection to the camera device and the snap-fit ​​connection of the openings 22 and the snap-fit ​​platform 23 to the camera device. When the camera device's snap-fit ​​is engaged with the snap-fit ​​platform 23 within the opening 22, the magnetic attraction structure simultaneously achieves a magnetic adsorption connection to the camera device, providing good operational convenience and accurate connection alignment.

[0051] Optionally, in this embodiment, the display device includes a circuit board 41, a reinforcing plate 42, and a quick-connect electrical connector 43. The circuit board 41 and the reinforcing plate 42 are disposed between the housing 20 and the display module 10. For example, the display module 10 may include a backlight component, that is, the circuit board 41 and the reinforcing plate 42 are disposed between the housing 20 and the backlight component. The quick-connect electrical connector 43 is used for electrical connection with the camera device. The circuit board 41 is electrically connected to the display module 10, the reinforcing plate 42 is connected to both the circuit board 41 and the housing 20, and the quick-connect electrical connector 43 is connected to the reinforcing plate 42 and passes through the housing 20. In this way, the circuit connection between the display module 10 and the camera module can be realized through the quick-connect electrical connector 43 and the circuit board 41 for power supply, data transmission, and communication, etc. Furthermore, the quick-connect electrical connector 43 is disposed on the reinforcing plate 42, so that the quick-connect electrical connector 43 has good connection stability. Specifically, the quick-connect electrical connector 43 passes through the mounting position 21 of the housing 20, and the quick-connect electrical connector 43 is exposed in the mounting position 21, so that the quick-connect electrical connector 43 and the camera device have good electrical connection stability.

[0052] In addition, the backlight component, such as the backlight panel, can be used as the housing 20. A receiving groove is provided on the backlight component, and the circuit board 41 and the reinforcing plate 42 are disposed in the receiving groove. The reinforcing plate 42 is connected to the circuit board 41 and the backlight component respectively. The quick electrical connector 43 is connected to the reinforcing plate 42 and passes through the backlight component. There is no need to set up a separate housing 20, which helps to reduce the thickness of the display device.

[0053] For example, in this embodiment of the application, the camera device is provided with electrical contact points, such as Pogo Pins. When the camera device is installed on the display device, the electrical contact points of the camera device contact the quick-connect electrical connector 43 of the display device to realize the electrical connection between the display device and the camera device, so that the two can perform relatively stable power supply, data transmission and communication, etc.

[0054] In this embodiment, the spring pin, also known as a pogo pin or pin, is a probe with a spring, typically used for connection or testing in electronic devices. It mainly consists of three parts: a plunger, a spring, and a barrel, formed by pre-pressing with precision instruments. Spring pins provide a stable electrical connection upon contact, while also possessing a certain degree of elasticity, allowing them to adapt to different contact surfaces. They offer good reliability, flexibility, and miniaturization, enabling reliable electrical connections between camera devices and display screens. Furthermore, they are widely applicable and easy to implement.

[0055] In this embodiment, for example, the number of quick electrical connectors 43 can be multiple, and these multiple quick electrical connectors 43 can be spaced apart along the length of the reinforcing plate 42, such as being evenly distributed or symmetrically distributed. Furthermore, the multiple quick electrical connectors 43 can also be arranged in an array, etc., to achieve multi-channel signal transmission. For example, the multiple quick electrical connectors 43 can be UART GND (Ground), UART TX (Transmit), UART RX (Receive), etc., so that the display device and the camera device can interact via UART (Universal Asynchronous Receiver / Transmitter). The specific configuration can be set according to actual needs, and this embodiment does not limit the specific number and configuration method of the quick electrical connectors 43.

[0056] For example, in this embodiment, the quick-connect electrical connector 43 can be a copper pillar. In addition, the material of the quick-connect electrical connector 43 can also be stainless steel or gold, etc., and the shape of the quick-connect electrical connector 43 can also be a cuboid or a cube, etc., which can be set according to actual needs. This embodiment does not limit the specific material and specific shape of the quick-connect electrical connector 43.

[0057] In this embodiment, for example, the circuit board 41 can be an FPC (Flexible Printed Circuit), also known as a flexible board, which has good flexibility and can be bent, so that the circuit board 41 can be bent and arranged according to actual layout needs. In addition, the circuit board 41 can also be a PCB (Printed Circuit Board), also known as a rigid board, which has good structural strength. The specific type of circuit board 41 is not limited in this embodiment.

[0058] In this embodiment, optionally, the number of openings 22 includes two, and the magnetic element 30 includes a first magnetic element 31 and a second magnetic element 32; the quick electrical connector 43 is disposed in the middle area of ​​the mounting position 21, with the first magnetic element 31 and the second magnetic element 32 respectively located on both sides of the quick electrical connector 43, and the two openings 22 are respectively disposed on the side of the magnetic attraction structure opposite to the quick electrical connector 43. In this way, when the camera device's latch is engaged with the latching platform 23 within the opening 22, the magnetic attraction structure simultaneously achieves magnetic adsorption connection of the camera device, and the quick electrical connector 43 enables circuit connection between the display device and the camera device, providing good operational convenience and accurate connection positioning.

[0059] Optionally, in this embodiment, the housing 20 has an opening 24 at a position opposite to the quick-connect electrical member 43, through which the quick-connect electrical member 43 passes; and / or, the quick-connect electrical member 43 is flush with the outer surface of the housing 20. Thus, the opening 24 provides space for the quick-connect electrical member 43 to pass through. For example, when there are multiple quick-connect electrical members 43, there are also multiple openings 24, with one quick-connect electrical member 43 passing through one opening 24. Furthermore, by setting the quick-connect electrical member 43 to be flush with the outer surface of the housing 20, the quick-connect electrical member 43 will not protrude from the housing 20, exhibiting better flatness and facilitating the contact point of the camera device to abut against the quick-connect electrical member 43.

[0060] Optionally, in this embodiment, the display device further includes an insulating sleeve 25, which is fitted onto the sidewall of the quick-connect electrical component 43, with the surface of the end of the quick-connect electrical component 43 furthest from the reinforcing plate 42 exposed. The insulating sleeve 25 provides circumferential insulation protection to the sidewall of the quick-connect electrical component 43, thereby giving the quick-connect electrical component 43 better electrical performance and reducing the risk of short circuits due to contact between the quick-connect electrical component 43 and other surrounding metal structures. For example, the insulating sleeve 25 can be a silicone sleeve or a rubber sleeve with a through cavity; the specific material and type of the insulating sleeve 25 are not limited in this embodiment.

[0061] Optionally, in this embodiment, the magnetic structure is disposed on the side of the housing 20 opposite to the display module 10; or, the magnetic structure is disposed at any position in the circumferential direction of the housing 20. In this way, the camera device can be connected to the back of the display device via the magnetic structure. Since there is no display device on the back of the display device, a larger arrangement area is available, facilitating layout. Alternatively, the magnetic structure can be disposed at any position in the circumferential direction of the housing 20, enriching the mounting positions 21 of the camera device and also giving the camera device a wider shooting angle.

[0062] For example, when the magnetic structure is provided on the back of the housing 20, the magnetic structure can be provided at the bottom end of the back of the housing 20 or at the top end of the back of the housing 20, so that the camera device can be provided at the bottom of the display device or at the top of the display device. The specific location of the camera device is not limited in the embodiments of this application.

[0063] Optionally, in this application embodiment, the display device is a vehicle-mounted display screen, which includes at least one of a plurality of display screens inside the vehicle. The display device in this application embodiment can be applied to a vehicle. For example, the vehicle-mounted display screen can be a display screen installed at a position relative to the driver's seat or the passenger seat, or it can be a display screen installed on the roof of the vehicle, or a display screen installed on the back of the seat, etc. This application embodiment does not limit the specific type of vehicle-mounted display screen.

[0064] For example, the vehicle display screen can be a front screen (also known as a central control screen), meaning that a mounting position 21 with a magnetic structure can be set on the front screen for mounting a camera device as a monitoring system for the vehicle cabin. The vehicle display screen can also be a ceiling-mounted screen, meaning that a ceiling-mounted screen connected to the roof can have a mounting position 21 with a magnetic structure for mounting a camera device as a monitoring system for the vehicle cabin. Finally, the vehicle display screen can be a seat screen, meaning a seat screen connected to the back of the seat can have a mounting position 21 with a magnetic structure for mounting a camera device as a monitoring system for the vehicle cabin.

[0065] Furthermore, mounting positions 21 with magnetic structures can be provided on both the front screen and the ceiling-mounted screen for mounting camera devices; or mounting positions 21 with magnetic structures can be provided on both the front screen and the seat screen for mounting camera devices; or mounting positions 21 with magnetic structures can be provided on both the seat screen and the ceiling-mounted screen for mounting camera devices; or mounting positions 21 with magnetic structures can be provided on the front screen, the ceiling-mounted screen, and the seat screen for mounting camera devices, serving as a monitoring system within the vehicle cabin. This application embodiment does not impose limitations on these aspects.

[0066] For example, in the embodiments of this application, the vehicle display screen can be a fixed screen, a foldable screen, etc. The specific type of vehicle display screen is not limited in the embodiments of this application.

[0067] Optionally, the display device includes a power module electrically connected to the camera device, and the display device supplies power to the camera device through the power module. This provides a relatively stable and reliable power supply from the display device to the camera device.
