Description

Technical Field

[0001] This utility model relates to the field of display technology, specifically a modular interface expansion backplane for displays. Background Technology

[0002] With the rapid development of display technology, displays have evolved from single display functions to intelligent terminals with multiple interfaces and interconnection of multiple devices. Their back panels not only need to support the basic function of fixing the display screen, but also need to integrate core components such as switch controllers, driver motherboards, and CNC units, while meeting the needs of interface expansion in different scenarios.

[0003] However, existing backplanes lack dedicated mounting structures for different functional components. Switch controllers, motherboards, CNC units, etc. are often directly fixed to the backplane surface with multiple sets of screws. During installation, the position needs to be repeatedly calibrated, and the components are prone to interference due to messy wiring. This not only increases assembly time but also makes component disassembly inconvenient during subsequent maintenance.

[0004] To address this, a modular interface expansion backplane for displays is proposed. Summary of the Invention

[0017] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments. Example

[0020] Please see Figures 1-5 This is the first embodiment of the present invention. This embodiment provides a modular interface expansion backplane for a display, including: a board body 1; Switch mounting assembly 2 is located on the front side of the plate 1; Support component 3 is disposed on the front of plate 1 and located at the bottom of switch mounting component 2; Motherboard mounting component 4 is located on the front of board body 1 and at the bottom of support component 2. The CNC unit mounting component 5 is located on the front side of the plate 1.

[0021] For example, the plate body 1 includes a first mounting plate 11, a second mounting plate 12 is fixedly mounted on the bottom of the first mounting plate 11, a third mounting plate 13 is fixedly mounted on the bottom of the second mounting plate 12, and a plurality of first card interfaces 14 are opened inside the second mounting plate 12.

[0022] Furthermore, the first mounting plate 11, the second mounting plate 12, and the third mounting plate 13 are made of one-piece molded aluminum alloy, which not only ensures the overall structural strength of the plate body 1, but also effectively reduces the weight, making it easier to install and transport the back plate; the multiple first card interfaces 14 are distributed at equal intervals, and the opening size is adapted to the card connection structure of the subsequent motherboard mounting component 4, providing a precise installation benchmark for the rapid positioning of the drive motherboard and avoiding positional deviation during installation.

[0023] For example, the switch mounting assembly 2 includes a mounting bracket 21, which is fixedly mounted on the front of the first mounting plate 11. A limiting shell 22 is provided on the front of the mounting bracket 21. A first screw hole 23 is provided at one end of the limiting shell 22, and two first snap-fit ​​pieces 25 are fixedly mounted at the other end of the limiting shell 22. Two second snap-fit ​​interfaces 24 are provided inside the mounting bracket 21, and the two first snap-fit ​​pieces 25 are respectively snapped into the inner side of the two second snap-fit ​​interfaces 24. A first screw hole 23 is provided at the bottom of the limiting shell 22.

[0024] Furthermore, the mounting bracket 21 is fixed to the front of the first mounting plate 11 by welding to ensure the stability of the connection and prevent the mounting bracket 21 from loosening due to vibration during long-term use; the limiting shell 22 is made of flame-retardant ABS material, which has good insulation and fire resistance, and can protect the internal switch controller; the outer side of the first snap-fit ​​piece 25 is provided with anti-slip ridges, which can increase friction after snapping into the second snap-fit ​​interface 24, preventing the limiting shell 22 from falling off before the bolts are fixed, and improving the safety during the assembly process.

[0025] For example, the support component 3 includes a support frame 31, which is fixedly mounted on the front side of the second mounting plate 12, and a limit frame 32 is fixedly mounted on the front side of the support frame 31.

[0026] Furthermore, when the limiting shell 22 is placed on top of the support frame 31, the limiting frame 32 can support the limiting shell 22, increasing the stability of the installation of the limiting shell 22.

[0027] For example, the bottom of the limiting shell 22 is located at the top of the support frame 31, and the first screw hole 23 is located on the front of the support frame 31.

[0028] Furthermore, the contact surfaces of the bottom of the limiting shell 22 and the top of the support frame 31 are flattened to ensure a tight fit between the two and prevent the limiting shell 22 from tilting. The support frame 31 has an internal threaded hole pre-set on the front corresponding to the position of the first screw hole 23, eliminating the need for on-site drilling. During assembly, the bolts can be directly passed through the first screw hole 23 and connected to the internal threaded hole, further simplifying the installation steps and improving assembly efficiency.

[0029] For example, the motherboard mounting assembly 4 includes a mounting shell 41. One end of the mounting shell 41 has a second screw hole 42, and the other end of the mounting shell 41 is fixedly mounted with two second snap-fit ​​pieces 43. The two second snap-fit ​​pieces 43 are respectively snapped into the inner side of the two first card interfaces 14.

[0030] Furthermore, the second snap-fit ​​piece 43 has elastic deformation capability. When it is snapped into the first snap-fit ​​interface 14, it can achieve a tight engagement through slight deformation. At the same time, it is easy to remove the snap-fit ​​piece during subsequent disassembly, thus taking into account both the stability of the fixation and the convenience of disassembly and assembly.

[0031] When using, assemble the switch controller: first fix the mounting bracket 21 on the first mounting plate 11, put the switch controller into the limiting shell 22, then align the first snap-fit ​​piece 25 of the limiting shell 22 with the second snap-fit ​​interface 24 of the mounting bracket 21 and snap it in so that the bottom of the limiting shell 22 rests on the support frame 31, and finally use bolts to pass through the first screw hole 23 at the bottom of the limiting shell 22 and fix it to the support frame 31 to complete the installation of the switch controller; Assemble the driver motherboard: Place the driver motherboard into the mounting shell 41, then align the second clip 43 of the mounting shell 41 with the first clip interface 14 of the second mounting plate 12 and snap it in. Then, use a bolt to thread it through the second screw hole 42 to connect it to the front of the second mounting plate 12. This completes the quick positioning and fixing of the motherboard without the need for repeated position calibration.

[0032] In summary, through the cooperation of the structure of board 1, switch mounting component 2, support component 3 and main board mounting component 4, the switch controller can be quickly positioned by the first snap-fit ​​piece 25 of the limiting shell 22 and the second snap-fit ​​piece of the mounting bracket 21 during assembly, and then fixed with bolts. The drive main board is precisely engaged and fixed by the second snap-fit ​​piece 43 of the mounting shell 41 and the first snap-fit ​​interface 14 of the second mounting plate 12, without the need for repeated calibration. At the same time, each component is installed in a partitioned manner through dedicated components, avoiding wiring interference, greatly reducing assembly time, and providing convenience for subsequent maintenance and disassembly. Example

[0033] Please see Figure 6 This is the second embodiment of the present utility model.

[0034] For example, the CNC unit mounting assembly 5 includes a fixing plate 51, which is fixedly mounted on the front of the third mounting plate 13. The fixing plate 51 has two third card interfaces 52 inside. The front of the fixing plate 51 is provided with two clamping frames 53. The bottom of each clamping frame 53 is provided with a third screw hole 54. The top of each clamping frame 53 is fixedly mounted with a third card contact piece 55. The two third card contact pieces 55 are respectively engaged with the inner side of the two third card interfaces 52.

[0035] Furthermore, the third card interface 52 is a long strip-shaped through groove, the length of which is designed according to the size range of common CNC units to ensure that the clamping frame 53 has enough adjustment space to adapt to CNC units of different widths; the inner side wall of the clamping frame 53 is provided with a wave-shaped anti-slip texture. When fixing the CNC unit, the anti-slip texture can increase the friction with the CNC unit shell to prevent the CNC unit from sliding during use, while avoiding excessive clamping force that could cause squeezing damage to the CNC unit shell.

[0036] When using the CNC unit, assemble it as follows: First, adjust the position of the two clamping frames 53 on the fixing plate 51 according to the width of the CNC unit. Slide the third clip 55 along the third clip interface 52 so that the distance between the two clamping frames 53 matches the width of the CNC unit. Then, place the CNC unit between the two clamping frames 53. After that, use a bolt to pass through the third screw hole 54 and make one end of the bolt threaded to the front of the fixing plate 51 to complete the fixing of the CNC unit. If you need to replace the CNC unit with a different size, simply loosen the fixing bolts of the clamping frame 53, adjust its position and fix it again to adapt to the new CNC unit. There is no need to replace the entire installation assembly, which greatly improves the versatility.

[0037] In summary, by adopting an adjustable clamping structure for the CNC unit mounting component 5, different width CNC units can be adapted to each other by sliding the clamping frame 53 during use, without the need to replace the entire mounting component, which greatly improves the versatility of the backplate for CNC units of different specifications.
