[0022] The structure provided by this utility model will be explained and described in detail below with reference to the accompanying drawings.

[0023] Example 1 refer to Figures 1 to 6 As shown, this embodiment specifically discloses a TV encryption device housing 1 for installing a motherboard 2. In this embodiment, the motherboard 2 is preferably an Orange Pi 5 Plus provided by Shenzhen Xunlong Software Co., Ltd., with a size of 100mm*75mm and a weight of about 80-90g. Of course, in some other embodiments, other types of motherboards can also be selected as needed. It should be noted that the focus of this embodiment is on the housing structure of the TV encryption device housing 1. The internal motherboard 2 is a motherboard that already exists in the prior art. Its specific working principle is well known to those skilled in the art and is not an improvement point of this embodiment. Therefore, it will not be described in detail here.

[0024] In this embodiment, the TV encryption device housing 1 includes a housing body 11, which includes a bottom plate 111, a top plate 112 disposed opposite to the bottom plate 111, and a front side plate 113, a rear side plate 114, a left side plate 115, and a right side plate 116 disposed between the top plate 112 and the bottom plate 111. A receiving cavity 117 for accommodating the motherboard 2 is formed between the bottom plate 111, the top plate 112, the front side plate 113, the rear side plate 114, the left side plate 115, and the right side plate 116. The receiving cavity 117 completely encloses the motherboard 2 in an independent space, while providing a certain degree of isolation from the external environment, such as dust, moisture, and minor collisions at the back of the TV. The bottom of the receiving cavity 117 is provided with multiple fixing posts 12. In the illustrated embodiment, there are four fixing posts 12. The fixing posts 12 correspond to the mounting holes at the four corners of the motherboard 2, and are used to detachably fix the motherboard 2 in the receiving cavity 117 with screws, so that a gap space 13 is formed between the bottom of the motherboard 2 and the bottom of the receiving cavity 117. Through the precise positioning design of the multiple fixing posts 12 corresponding to the mounting holes at the four corners of the motherboard 2, and with the screws, detachable fixing is achieved, which restricts the lateral or longitudinal displacement of the motherboard in the receiving cavity 117. This can prevent the motherboard from loosening due to TV vibration (such as power on / off, subwoofer resonance), and prevent poor contact of the motherboard 2 interface, thereby ensuring that the audio and video data encryption is not interrupted. Moreover, the detachable fixing allows for quick disassembly of the motherboard 2 compared to glue fixing, which is conducive to quick maintenance and reduces the later maintenance costs. In addition, the fixing posts 12 support the motherboard 2, so that the bottom of the motherboard 2 and the bottom of the receiving cavity 117 form a gap space 13, which provides an air circulation channel, while preventing the bottom of the motherboard 2 from directly contacting the base plate 111, which can reduce heat accumulation caused by heat conduction.

[0025] The front panel 113 has multiple openings 14 corresponding to the interfaces on the motherboard 2, and the inner diameter of the opening 14 is 0.2mm larger than the outer diameter of the corresponding interface. In the illustrated embodiment, the opening 14 includes a power interface opening 141, an Ethernet interface opening 142, an HDMI output interface opening 143, an HDMI input interface opening 144, and a USB interface opening 145. These openings 14 correspond one-to-one with the interfaces on the motherboard 2, ensuring that the interfaces are fully exposed and do not obstruct cable insertion or removal. The inner diameter of the opening is 0.2mm larger than the outer diameter of the interface to avoid scratches on the interface or cable jamming due to excessive tightness. Simultaneously, the slight allowance accommodates minor size differences between interfaces from different brands, eliminating the need for separate molds for specific interfaces and reducing production costs.

[0026] Both the left side panel 115 and the right side panel 116 are provided with strip grilles 19 for heat dissipation; the strip grilles 19 on both the left and right side panels form a two-way air convection channel with air intake on the left and air exhaust on the right or air intake on the right and air exhaust on the left. By utilizing the natural airflow at the rear of the TV, the heat in the housing cavity 117 is discharged, avoiding the accumulation of internal heat.

[0027] Specifically, the TV encryption device housing provided in this embodiment has multiple fixing posts 12, which can be used to detachably install and fix the motherboard 2 in the receiving cavity 117. At the same time, after installation, the gap space 13 formed between the motherboard 2 and the bottom of the receiving cavity 117, i.e., the base plate 111, can facilitate the heat dissipation of the motherboard 2 and avoid the motherboard 2 from being affected by poor heat dissipation. The overall structure is simple and occupies little space.

[0028] Continue to refer to Figures 1 to 3As shown, the upper part of the left side plate 115 and the right side plate 116 are bent inward for a short period and then extended upward to form a connecting part 15, and a first connecting hole 151 is provided on the connecting part 15; the left and right ends of the top plate 112 are bent downward to form a folded edge 16, and a second connecting hole 161 corresponding to the first connecting hole 151 is provided on the folded edge 16.

[0029] The first connecting hole 151 and the second connecting hole 161 are aligned and connected by bolts or rivets, thereby realizing the detachable connection between the top plate 112 and the left and right side plates, which facilitates subsequent maintenance. In addition, the bent edge 16 fits tightly with the connecting part 15, which can effectively prevent dust and liquid from entering, thus providing better protection for the internal main board 2.

[0030] Similarly, the top of the front side panel 113 and the rear side panel 114 are formed with inwardly bent extension plates 17; the top surface of the extension plates 17 formed after bending inward is in contact with the bottom surface of the top panel 112, and at the same time connects with the ends of the connecting parts 15 of the left and right side panels, which can provide better support for the installation of the top panel 112; it can also further prevent external liquids or dust from entering from the gap between the top panel and the side panels.

[0031] Example 2 Continue to refer to Figures 4 to 6 This embodiment provides a TV encryption device, which has the TV encryption device housing 1 as in Embodiment 1. A motherboard 2 is installed inside the housing 1. In the illustrated embodiment, the motherboard 2 is preferably an Orange Pi 5 Plus provided by Shenzhen Xunlong Software Co., Ltd., with a size of 100mm*75mm and a weight of about 80-90g.

[0032] Understandably, the Orange Pi 5 Plus uses Rockchip's new-generation octa-core 64-bit ARM processor, the RK3588, specifically a quad-core A76 and a quad-core A55. It uses Samsung's 8nm LP process technology, with the large cores reaching a maximum frequency of 2.4GHz. It integrates an ARM Mali-G610 MP4 GPU, embeds high-performance 3D and 2D graphics acceleration modules, and has a built-in AI accelerator NPU with up to 6 TOPS of computing power. It offers options of 4GB, 8GB, 16GB, or 32GB of memory and has up to 8K display processing capabilities.

[0033] The Orange Pi 5 Plus boasts a rich array of interfaces, including two HDMI outputs, one HDMI input, a USB-C / DP port, four M.2 M-key PCIe 3.0 ports, one M.2 E-key PCIe 2.0 port, two 2.5G Ethernet ports, an eMMC expansion port, USB 2.0 ports, USB 3.0 ports, an infrared port, headphone jack, onboard microphone, speaker, RTC, and a 40-pin expansion header. It is widely applicable to high-end tablets, edge computing, artificial intelligence, cloud computing, AR / VR, smart security, smart home, and other fields, covering various AIoT industries.

[0034] The Orange Pi 5 Plus supports Orange Pi OS, the official operating system developed by Orange Pi, and also supports Android 12.1, OpenWRT, Debian 11, Debian 12, Ubuntu 20.04, and Ubuntu 22.04. It can be used to implement a Linux desktop computer, a Linux network server, an Android tablet, an Android game console, etc. In this invention, it is used to implement television encryption.

[0035] In this embodiment, combined with relevant hardware interfaces, the basic interaction process is as follows: External devices, such as set-top boxes and mobile screen mirroring devices, are connected via the HDMI IN interface on the motherboard to receive raw audio and video data streams (such as HDMI signals), which can be temporarily stored in the motherboard's memory buffer. Then, the motherboard's encryption module encrypts the raw audio and video data streams to obtain encrypted signals. The encrypted signal is connected to the TV through the HDMI OUT interface of the motherboard, outputting encrypted audio and video data. After the TV receives the signal and detects the encryption identifier, it can automatically send a decryption request to the encryption device. After the motherboard verifies that the TV is an authorized device, it sends back the decryption key, thereby restoring the encrypted audio and video data to the original picture.

[0036] The above process is only an illustrative description, and specific designs can be made according to different situations.

[0037] Furthermore, such as Figure 6As shown, to achieve stable installation and fixation of the TV encryption device, the TV encryption device also includes a bracket 3 connected to the bottom of the shell body 11. The bracket 3 has a basic grid-like outline and several round holes arrayed on the bracket 3 for installation and fixation. Four bracket connection holes 18 are provided on the bottom plate 111 of the shell body 11. The bracket 3 is detachably connected and fixed to the shell body 11 through the bracket connection holes 18. By fixing the bracket 3 to the wall or cabinet in the space behind the TV, the TV encryption device can be installed and fixed, achieving concealed installation at the rear of the TV and significantly improving space adaptability.
