[0030] See Figures 1 to 4 Referring to the specific embodiment shown, the present utility model discloses a chassis structure based on a Raspberry Pi development board, including: a box body 10, a Raspberry Pi development board 20 installed inside the box body 10, a PCIe to M.2 expansion board 30, an OLED screen expansion board 40, and a Type-C & HDMI adapter board 50. The OLED screen expansion board 40 and the Type-C & HDMI adapter board 50 are electrically connected to the Raspberry Pi development board 20. The Raspberry Pi development board 20 is electrically connected to the PCIe to M.2 expansion board 30, and the PCIe to M.2 expansion board 30 is installed with an M.2 solid-state drive.

[0031] Specifically, the Raspberry Pi development board 20 and the PCIe to M.2 expansion board 30 are distributed horizontally and connected. The Raspberry Pi development board 20 and the Type-C & HDMI adapter board 50 are directly connected horizontally through three horizontal interfaces. The function of the Type-C & HDMI adapter board 50 is to convert the micro HDMI and Type-C interfaces on the side of the Raspberry Pi development board 20 to the interface panel at the network port end, achieving the interface integration of the Raspberry Pi development board 20, making the entire chassis structure design compact, simple to assemble, and small in size, improving the user experience. In addition, by installing an M.2 solid-state drive through the PCIe to M.2 expansion board 30, external storage is added to the Raspberry Pi development board 20, greatly improving the data read and write speed and storage capacity. Compared with traditional SD cards or USB storage devices, the M.2 solid-state drive has obvious advantages in speed, which is particularly important for scenarios that require processing a large amount of data or running high-performance applications. In addition, the addition of the OLED screen expansion board 40 enables the Raspberry Pi development board 20 to directly connect to and control the OLED screen for display, which is very useful in applications that require a graphical interface or real-time data display, such as embedded systems, smart home control panels, etc. The high contrast, low power consumption, and fast response of the OLED screen also improve the user experience. In addition, the Type-C & HDMI adapter board 50 provides more diverse interface options for the Raspberry Pi development board 20. The Type-C interface supports high-speed data transmission and power transmission, facilitating the connection of modern devices, while the HDMI interface allows the Raspberry Pi development board 20 to directly connect to a high-definition monitor or TV for video output, which is very suitable for multimedia applications and the education field. In addition, the entire chassis structure is designed compactly, and the connection between components is simple and clear. This not only reduces the overall volume but also facilitates user assembly and maintenance. This design enables the Raspberry Pi development board 20 to have a wider range of application scenarios and can easily handle desktop-level projects and portable devices. In addition, through the above hardware expansion and performance improvement, this chassis structure provides a more smooth and efficient operation experience for users of the Raspberry Pi development board 20. Whether it is data processing, graphics display, or device connection, better support can be obtained, thereby improving the overall satisfaction of users.

[0032] Among them, the function of reading data such as the CPU, RAM, and temperature of the Raspberry Pi development board 20 can also be realized by controlling the OLED display. That is, the user can directly view the real-time operating status of the Raspberry Pi development board 20 on the OLED screen, including key indicators such as CPU usage, RAM usage, and system temperature. This instant data feedback is crucial for system monitoring and performance tuning. When there are performance bottlenecks or anomalies in the system, the user can quickly locate the problem through the data on the OLED screen, thereby conducting targeted troubleshooting and resolution. Additionally, without connecting an additional monitor or logging in to the Raspberry Pi development board 20 remotely via SSH, etc., the user can intuitively obtain system status information, greatly enhancing the convenience of operation. Moreover, in an embedded system, due to limited space and often no additional monitor, this technology is particularly important as it enables the user to keep track of the system's health at any time and ensure the stable operation of the system.

[0033] In one embodiment, a main control module mounting board 60 is provided inside the box body 10, and the PCIe to M.2 expansion board 30 and the Type-C & HDMI adapter board 50 are connected to the main control module mounting board 60.

[0034] Specifically, through the main control module mounting board 60, key components such as the PCIe to M.2 expansion board 30 and the Type-C & HDMI adapter board 50 can be installed inside the box body 10 orderly and stably. This modular design makes the connection between each component clearer and more standardized, facilitating subsequent maintenance and upgrading. Additionally, the main control module mounting board 60 provides a stable installation foundation for the PCIe to M.2 expansion board 30 and the Type-C & HDMI adapter board 50, reducing signal interference or transmission problems caused by unstable connections and improving the stability and reliability of the system. Moreover, the design of the main control module mounting board 60 usually takes into account the issues of heat dissipation and layout optimization to ensure that each component can maintain good heat dissipation performance during operation, avoiding performance degradation or damage caused by overheating.

[0035] Preferably, the main control module mounting board 60 is made of acrylic material. The acrylic board has relatively high mechanical strength and can withstand a certain amount of pressure and impact, ensuring stability and safety during installation and use. Additionally, when environmental factors such as temperature and humidity change, the performance of the acrylic material is relatively stable and is not prone to deformation or damage, thereby ensuring the long-term stability and reliability of the main control module mounting board 60. Moreover, the acrylic board has good processing performance and can be processed through various processes such as cutting, drilling, and heat bending to meet the requirements of different shapes and sizes, which makes the production of the main control module mounting board 60 more flexible and convenient.

[0036] In one embodiment, welding mesh plates 70 are provided at the top and bottom of the box body 10. The welding mesh plates 70 are provided with mounting holes 71, and the main control module mounting plate 60 is connected to the mounting holes 71.

[0037] Specifically, the use of the welding mesh plates 70 significantly improves the overall load-bearing capacity of the box body 10, making the box body 10 more stable when carrying hardware such as the main control module mounting plate 60 and the expansion board, and reducing the risk of hardware loosening or damage caused by vibration or external forces. In addition, the mounting holes 71 on the welding mesh plates 70 provide a standardized mounting interface for the main control module mounting plate 60, making the installation process more simple and fast; at the same time, this design also facilitates subsequent maintenance and upgrade work, and users can easily replace or upgrade hardware such as the expansion board according to needs. In addition, through reasonable layout and design, the welding mesh plates 70 and their mounting holes 71 can make full use of the space inside the box body 10, enabling each hardware component to be arranged compactly and orderly together, improving the space utilization rate.

[0038] In one embodiment, the welding mesh plates 70 are further provided with heat dissipation holes, and a dust-proof filter element 80 is provided on the outer surface of the heat dissipation holes.

[0039] Specifically, the design of the heat dissipation holes allows the air inside and outside the box body 10 to circulate, thereby effectively dissipating the heat generated by the Raspberry Pi development board 20, the expansion board and other hardware during operation, which is of great significance for maintaining the stable operation of the system and preventing hardware overheating. In addition, through the heat dissipation holes, a convection can be formed inside the box body 10 to accelerate the air circulation, reduce heat accumulation, and improve the overall heat dissipation effect. In addition, the setting of the dust-proof filter element 80 effectively blocks impurities such as dust and particulate matter from entering the inside of the box body 10, protecting the internal hardware from pollution and damage, which is of great importance for extending the service life of the hardware and improving the system stability. In addition, the dust-proof filter element 80 also has a certain protective effect, which can prevent insects, small animals, etc. from entering the inside of the box body 10, further enhancing the safety and reliability of the system. In addition, the combined design of the heat dissipation holes and the dust-proof filter element 80 ensures that the box body 10 has a certain air permeability while maintaining the ventilation inside the box body 10, which is of great significance for preventing adverse effects caused by air pressure changes inside the box body 10.

[0040] Preferably, the dust-proof filter element 80 is a magnetic adsorption mesh plate, and the magnetic adsorption mesh plate is adsorbed on the outer surface of the heat dissipation holes of the welding mesh plate 70 by magnetic force, without using fixing methods such as screws and glue, and the installation process is simple and fast. When cleaning or replacement is required, the user can easily remove the magnetic adsorption mesh plate from the welding mesh plate 70 without complicated disassembly steps.

[0041] In one embodiment, the PCIe to M.2 expansion board 30 and the Type-C & HDMI adapter board 50 are connected to the main control module mounting board 60, and the Raspberry Pi development board 20 is connected to the PCIe to M.2 expansion board 30 through short copper pillars.

[0042] Specifically, the use of short copper pillars makes the connection between each board card more compact, effectively reducing the volume and occupied space of the overall structure, which is particularly important for application scenarios with limited space, such as embedded systems, small servers, etc. In addition, the compact structural design helps to improve the integration of the system, enabling more functions to be realized within a limited space and meeting the requirements of modern electronic devices for high integration. In addition, although the main function of the short copper pillars is not heat dissipation, they can, to a certain extent, serve as a medium for heat conduction; when heat is generated during system operation, it can be transferred to the radiator or other heat dissipation devices through components such as the board card and short copper pillars, helping to reduce the operating temperature of the system. In addition, the connection method using short copper pillars enables the system to adapt to a variety of different application scenarios and installation environments. Whether it is horizontally installed or vertically installed, it can be achieved by adjusting the length and layout of the short copper pillars. In addition, with the continuous increase in the demand for system function expansion and upgrade, the connection method using short copper pillars also provides the possibility for future expansion. The system's functions and performance can be expanded by adding additional board cards and short copper pillars.

[0043] In one embodiment, an RGB strip light 90 is further provided inside the box body 10, and the RGB strip light 90 is electrically connected to the OLED screen expansion board 40.

[0044] Specifically, the RGB strip light 90 can emit light of three primary colors: red, green, and blue. By adjusting the brightness and mixing ratio of these three colors, rich color changes can be achieved. This colorful light effect can significantly enhance the visual attraction of the cabinet 10 and bring a more vivid and lively visual experience to users. Additionally, by adjusting the color and brightness of the RGB strip light 90, different atmospheres and scenes can be created. For example, in an e-sports scenario, bright and dynamic lighting effects can be used to stimulate the fighting spirit of players; in a display or exhibition occasion, soft and warm lighting can be used to create a comfortable viewing environment. Moreover, since the RGB strip light 90 is electrically connected to the OLED screen expansion board 40, synchronous display with the content of the OLED screen can be achieved. This synchronous display not only enhances the coherence and coordination of the overall visual effect but also provides a more immersive experience for users. For example, when playing videos or games, the lighting effects can change with the changes in the screen content, creating a more realistic scene effect. Additionally, through programming and control systems, interaction between the RGB strip light 90 and the OLED screen can also be achieved. For example, users can control the color and brightness of the lights by touching the screen or using a remote control to achieve personalized lighting effect settings. This interactive experience not only increases the user's sense of participation and fun but also enhances the added value of the product.

[0045] In one embodiment, an RGB cooling fan 100 is further provided inside the cabinet 10, and the RGB cooling fan 100 is electrically connected to the OLED screen expansion board 40.

[0046] Specifically, with its strong wind force, the RGB cooling fan 100 can effectively discharge the heat inside the cabinet 10 and reduce the temperature of the OLED screen expansion board 40 and the surrounding hardware. This is of great significance for ensuring that the OLED screen expansion board 40 and other electronic components operate at an appropriate temperature and preventing performance degradation or damage caused by overheating. Additionally, the RGB cooling fan 100 not only has a heat dissipation function but also has built-in RGB lighting effects. These lighting effects can be programmed and controlled to achieve various color and brightness changes, adding a touch of bright color to the inside of the cabinet 10. This visual embellishment not only enhances the overall aesthetics of the device but also brings a more personalized experience to users. Moreover, similar to the RGB strip light 90, the lighting effects of the RGB cooling fan 100 can also be used to create different atmospheres and scenes. By adjusting the color and brightness of the lights, different visual effects such as warm, dynamic, or sci-fi can be created according to needs.

[0047] In one embodiment, the PCIe to M.2 expansion board 30 is further provided with a PCIe cable, and the PCIe cable is electrically connected to the Raspberry Pi development board 20.

[0048] Specifically, PCIe (Peripheral Component Interconnect Express) is a high-speed serial computer expansion bus standard. Compared with traditional parallel buses, PCIe has higher data transfer rates and lower system latency. The Raspberry Pi development board 20 is connected to the PCIe to M.2 expansion board 30 through a PCIe cable, and these advantages of the PCIe interface can be utilized to achieve high-speed data transfer with high-speed storage devices such as M.2 solid-state drives. Additionally, PCIe is a standardized interface standard with wide compatibility and stability. By using a PCIe cable and the PCIe to M.2 expansion board 30, the Raspberry Pi development board 20 can be connected to various devices compliant with the PCIe standard, reducing system problems caused by interface incompatibility or signal instability.

[0049] In one embodiment, a Type-C interface is further provided on the box body 10, and the Type-C interface is electrically connected to the Raspberry Pi development board 20.

[0050] Specifically, the Type-C interface, as a currently widely adopted charging and data transfer interface, has high versatility. By setting a Type-C interface on the box body 10 and electrically connecting it to the Raspberry Pi development board 20, users can easily power the Raspberry Pi development board 20 using a Type-C wire without having to search for a specific power adapter or interface. Additionally, compared with traditional power interfaces, the Type-C interface has a smaller volume and a more concise plugging and unplugging method, making the power connection process more convenient. Users only need to insert the Type-C wire into the interface on the box body 10 to complete the power connection without worrying about interface mismatch or difficult plugging and unplugging problems.

[0051] In one embodiment, the box body 10 is composed of a box frame 11, side plates 12, and a front plate 13. One of the side plates 12 is a black-transparent acrylic plate, and the other side plate 12 and the front plate 13 are both transparent acrylic plates.

[0052] Specifically, the transparent acrylic board has high light transmittance, and the light transmittance can reach more than 90%, making the components, equipment or exhibits inside the box body 10 clearly visible, enhancing the overall sense of transparency and modernity. In addition, the combination of the black transparent acrylic side plates 12 with the transparent acrylic side plates 12 and the front plate 13 provides a richer visual hierarchy for the content inside the box body 10 through the contrast of colors and the difference in transparency, making the display effect more three-dimensional and vivid. In addition, the transparent acrylic material makes the situation inside the box body 10 clear at a glance, and users can easily observe the operating state of the equipment or whether there are any abnormal situations, so as to carry out maintenance or adjustment in time. In addition, the surface of the transparent acrylic is smooth, not easy to be stained with stains, and easy to clean. When it is necessary to clean the box body 10, just gently wipe it with a soft cloth to restore its original transparency and beauty.

[0053] In one embodiment, support feet pads 110 are provided at the four corners of the bottom of the box body 10.

[0054] Specifically, as a key component for the box body 10 to contact the ground, the support feet pads 110 need to bear the weight of the entire box body 10. The support feet pads 110 are made of rubber material, and the rubber material has good load-bearing capacity, which can effectively support the weight of the box body 10 and prevent the box body 10 from deforming or being damaged due to uneven force. In addition, the support feet pads 110 distributed at the four corners can provide stable support points to ensure the stability of the box body 10 during placement and movement, and prevent it from tipping or shaking due to external forces. In addition, when the rubber material support feet pads 110 contact the ground, they can generate a large frictional force, thus effectively preventing the box body 10 from sliding on a smooth ground and ensuring the stability of the box body 10 in a stationary state. In addition, the rubber material has good elasticity and can absorb and relieve the vibration and impact force generated when the box body 10 moves or is impacted by external forces to a certain extent, protecting the components inside the box body 10 from being damaged.

[0055] The above embodiments are the preferred implementation solutions of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the present invention.
