Description

Technical Field

[0001] This utility model relates to the field of display device technology, specifically to a backlit rotating screen. Background Technology

[0002] In the field of modern display technology, backlit rotating screens, as devices that combine display functionality with adjustable viewing angles, have been widely used in various commercial displays, advertising, and information dissemination scenarios. However, existing backlit rotating screens have several problems that need to be addressed in practical use, mainly including:

[0003] (1) The internal structure of traditional backlight rotating screens is usually relatively closed. When it is necessary to repair, replace or upgrade key components such as the lamp board and light guide plate inside the screen, it often requires professional technicians to use complex tools and spend a lot of time and effort to open the screen shell and access the internal structure. This undoubtedly increases maintenance costs and reduces the maintainability of the equipment.

[0004] (2) Most backlight rotating screens use traditional fixed power interfaces, which not only restricts the installation location of the equipment, requiring it to be close to a specific power socket, but also requires ensuring that the interface specifications match when connecting to an external power source. If the interfaces are incompatible, an additional converter is required, which increases the inconvenience of use.

[0005] (3) Existing backlit rotating screen designs are relatively simple and lack innovation and variation. The front opening edge area of ​​the screen is mostly a simple planar structure, which cannot meet users' needs for diverse and personalized screen appearances, making it difficult to stand out among many display devices and attract users' attention. Utility Model Content

[0034] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] like Figure 1-6 As shown, this utility model provides a backlit rotating screen. By setting a rotatable lamp plate mounting bracket 8, it is convenient to maintain the inside of the screen. In addition, by setting an extension 101, the appearance of the screen can be varied and its functions can be expanded.

[0036] The backlight rotating screen mainly consists of a hollow frame 1 and a back panel 2. The back panel 2 covers the rear opening of the frame 1, forming a closed internal space.

[0037] A PCB board 3 is mounted on the front end of the back panel 2. The PCB board 3 is supported by several protrusions 201 on the front end of the back panel 2, so that the PCB board 3 is suspended in front of the back panel 2 and fixed. This design can ensure that there is a certain space between the PCB board 3 and the back panel 2, which is convenient for heat dissipation and circuit layout.

[0038] Several LEDs 4 are arranged in a matrix on the PCB board 3. These LEDs 4 can project light onto the front end of the frame 1, providing uniform backlighting for the subsequent display. The matrix arrangement of the LEDs 4 can ensure uniform light distribution and avoid uneven brightness.

[0039] A rotating base 5 is fixedly connected to the inner wall of frame 1, and a PCB conductive component 6 is disposed inside the rotating base 5. One end of the PCB conductive component 6 is electrically connected to the PCB board 3, and the other end is connected to a USB conductive cable 7 extending outward from frame 1. This design allows the PCB board 3 to be connected to an external power supply or control device via the USB conductive cable 7 to achieve power supply and signal transmission.

[0040] The rear panel 2 has an opening 202 for displaying the rear end face of the rotating base 5. The rear end face of the rotating base 5 has a wiring hole 501 for installing and fixing the USB conductive cable 7. Simultaneously, the rear end face of the rotating base 5 also has several heat dissipation holes 502, distributed on both sides of the wiring hole 501. This design facilitates the installation and fixing of the USB conductive cable 7, and also improves the heat dissipation of the rotating base 5, thus enhancing the stability and reliability of the device.

[0041] A rotatable light panel mounting bracket 8 is installed within the frame 1. The light panel mounting bracket 8 is connected to one end of the rotating base 5 via a pivot assembly 9. The pivot assembly 9 consists of two sets of rotating fixed shafts 901 and rotating sleeves 902 used in conjunction. The two rotating fixed shafts 901 are fixed to both sides of the rotating base 5, and one end of each rotating sleeve 902 is fixed to both ends of the frame 1 via a first locking member 12. The other ends of each rotating sleeve 902 are inserted into the corresponding rotating fixed shaft 901 to form a forward-flipping structure. Through this design of the pivot assembly 9, the light panel mounting bracket 8 can be flipped forward around the pivot assembly 9, facilitating maintenance of the screen's interior.

[0042] When maintenance of the screen's interior is required, the user can manually push the light panel mounting bracket 8 to flip it forward around the rotating shaft assembly 9. During the flipping process, the rotating fixed shaft 901 rotates within the rotating sleeve 902, achieving the forward flipping of the light panel mounting bracket 8.

[0043] A light guide plate 10 and a panel 11 are sequentially arranged on the light panel mounting bracket 8 along the direction away from the back panel 2. The light guide plate 10 covers all the LED lights 4 and can guide the light projected by the LED lights 4 to the panel 11, making the display content on the panel 11 clearer and more uniform.

[0044] The lamp panel mounting bracket 8 is provided with a limiting mounting groove 801 for stacking light guide plates 10 and panels 11 in sequence. The light guide plates 10 and panels 11 are provided with several second locking members 13 around their perimeter, which are inserted into and locked to the bottom of the limiting mounting groove 801. This design can ensure the stable installation of the light guide plates 10 and panels 11 on the lamp panel mounting bracket 8 and prevent displacement or shaking during use.

[0045] The front opening of the frame 1 has several circumferentially rotatable extensions 101, which can be flipped inwards and outwards. These extensions 101 are connected to the frame 1 via pivot pins. When the extensions 101 are flipped inwards towards the frame 1, they cover the edge area of ​​the panel 11, thus protecting it. One of the extensions 101 has a perforated pattern section 102, increasing the screen's appearance and functional expandability; for example, it can be used to display brand logos, decorative patterns, etc.

[0046] In use, when an external power source supplies power to the PCB board 3 via the USB conductive cable 7, the LEDs 4 on the PCB board 3 emit light. The light is guided by the light guide plate 10 and evenly illuminates the panel 11, thus achieving the display function. When maintenance is required, the extension 101 flips outward, and the user can manually push the lamp board mounting bracket 8 forward to flexibly adjust the screen display angle using the hinge assembly 9 before performing maintenance.

[0047] Compared with traditional technologies, the backlit rotating screen provided by this technical solution can quickly expose the internal structure of the screen by setting a forward-rotating lamp plate mounting bracket 8 inside, which is convenient for users to maintain the internal structure of the screen. It uses a USB conductive cable 7 for power connection. The USB interface has wide compatibility and can be easily connected to various external power devices. In addition, the plugging and unplugging of the USB conductive cable 7 is simple and convenient, which improves the flexibility of the device. The extension 101 with the front opening of the frame 1 further improves the practicality and personalization of the screen by opening a hollow pattern part 102.

[0048] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
