[0027] This utility model proposes an extension bracket.

[0028] Please see Figure 1and Figure 2 In one embodiment of the present invention, the expansion bracket includes a housing 10, the housing 10 having an installation space and a connection port 10a, the installation space being used to install a computer host, and the connection port 10a communicating with the installation space to expose the various interfaces of the computer host.

[0029] In one embodiment of the present invention, the expansion bracket includes a housing 10, the housing 10 having an installation space and a connection port 10a, the installation space being used to install a computer host, and the connection port 10a communicating with the installation space to expose the various interfaces of the computer host.

[0030] The housing 10 is the basic structure of the expansion stand, and its internal mounting space is designed to accommodate the mini PC host, ensuring that the host can be placed stably within it.

[0033] During use, the mini PC host is installed into the mounting space of the housing 10. The protective pad 50 acts as a buffer and fixation during installation, ensuring the host is stably placed within the bracket. The connection port 10a on the housing 10 communicates with the mounting space, allowing all the host's interfaces to be fully exposed, enabling users to easily connect various external devices. This design not only solves the problem of insufficient interfaces in the mini PC host but also provides additional physical protection for the host through the structural design of the protective pad 50 and the housing 10, enhancing its stability and reliability during use.

[0034] This utility model, through the coordinated design of the housing 10, installation space, and connection port 10a, effectively solves the problem of insufficient interfaces in mini PC hosts and provides reliable physical protection for the host computer. The rational layout of the connection port 10a fully exposes the host's interfaces, allowing users to easily connect various external devices, thus significantly improving the expandability and practicality of the mini PC host. This design not only optimizes the user experience but also extends the lifespan of the mini PC host, providing users with a more efficient, stable, and convenient operating environment.

[0035] In one embodiment, please refer to Figure 2 , Figure 3 and Figure 4 The expansion bracket also includes a motherboard 20 and an expansion interface 30 electrically connected to the motherboard 20. Both the motherboard 20 and the expansion interface 30 are installed in the installation space. Both the expansion interface 30 and the motherboard 20 are spaced apart from the connection port 10a. The expansion interface 30 is used to expand the computer host interface.

[0036] The motherboard 20 is one of the core components of the expansion bracket, installed within the mounting space of the housing 10. It connects to the mini-PC host via a circuit design, serving as a signal relay and expansion unit. The motherboard 20 integrates various electronic components and circuits, enabling data transmission, signal conversion, and power management. Its design fully considers compatibility with the mini-PC host, ensuring stable data reception and transmission.

[0037] Expansion Interface 30 is an external interface connected to the motherboard 20 and also installed within the mounting space. These interfaces include, but are not limited to, USB ports, HDMI ports, RJ45 network ports, and SD card slots. Expansion Interface 30 connects to the internal interfaces of the mini PC host via the motherboard 20, thereby enabling functional expansion. The design of Expansion Interface 30 enriches the mini PC host's connectivity options, meeting users' needs for connecting various external devices, such as external hard drives, monitors, network devices, and card readers.

[0038] In this embodiment, the connection port 10a is spaced apart from the expansion interface 30 and the motherboard 20 to ensure that the expansion interface 30 and the host interface do not interfere with each other, while allowing users to choose to use the host's native interface or the expansion interface 30 according to their needs.

[0039] During use, the mini PC is installed in the expansion bracket's mounting space, with its native interfaces exposed via connector 10a for direct user access. Simultaneously, the motherboard 20 is connected to the mini PC's internal interfaces via circuitry. The expansion interface 30 receives signals from the PC through the motherboard 20 and converts them into other types of interface signals. Users can connect more external devices via the expansion interface 30, such as an external hard drive to increase storage space or a monitor to expand display functionality. The collaborative work of the motherboard 20 and the expansion interface 30 allows the mini PC to overcome the limitations of its native interfaces and achieve greater functional expansion.

[0040] This embodiment, through the design of the motherboard 20 and expansion interface 30, effectively solves the problem of insufficient interfaces in mini PC hosts. The motherboard 20, as the core of signal relay, can stably communicate with the mini PC host, while the expansion interface 30 provides users with more connection options, meeting the connection needs of various external devices. This design not only improves the expandability and compatibility of the mini PC host, but also avoids mutual interference between interfaces through a reasonable layout (the expansion interface 30 and the connection port 10a are spaced apart), ensuring the stability and reliability of signal transmission. Ultimately, users can use the mini PC host more flexibly, greatly improving its practicality in office, entertainment, and data processing scenarios, and optimizing the overall user experience.

[0041] In one embodiment, please refer to Figure 3 , Figure 4 and Figure 5 The expansion bracket also includes a solid-state drive 40 installed in the installation space. The solid-state drive 40 is electrically connected to the motherboard 20 and is spaced apart from the motherboard 20 and the expansion interface 30. The solid-state drive 40 is used for expanded storage.

[0042] Solid-state drive (SSD) 40 is a flash memory-based storage device with advantages such as fast read / write speeds, good shock resistance, and low power consumption. Internally, it mainly consists of a controller chip, flash memory chips, and firmware. The controller chip is responsible for managing data storage, optimizing read / write speeds, and performing wear leveling. SSD 40 connects to motherboard 20 via interfaces such as SATA, M.2, or PCIe.

[0043] The motherboard 20 is the core component of the expansion bracket, used to connect and manage the solid-state drive 40 and other expansion interfaces 30. The motherboard 20 has dedicated interfaces (such as SATA or M.2 slots) for receiving data signals from the solid-state drive 40 and transmitting them to the computer host. The solid-state drive 40 connects to the motherboard 20 via a data cable (such as a SATA cable) and a power cable. The data cable transmits data signals, while the power cable provides power to the solid-state drive 40.

[0044] In the expansion bracket, the solid-state drive 40 is electrically connected to the motherboard 20 via its interface (such as SATA or M.2). The motherboard 20 receives data signals from the solid-state drive 40 and transmits them to the mini-PC host, thereby enabling data read and write operations. The main controller chip of the solid-state drive 40 is responsible for managing data storage and optimizing read and write speeds. Through spacing settings, a reasonable spatial layout is maintained between the solid-state drive 40, the motherboard 20, and the expansion interface 30 to avoid signal interference and ensure the stability and efficiency of data transmission.

[0045] By integrating a solid-state drive (SSD) 40 into the expansion bracket, the MiniPro hard drive expansion bracket not only solves the problem of insufficient storage capacity in mini PCs but also significantly improves data read and write speeds. The high-speed characteristics of the SSD 40 result in shorter boot times and faster file transfers. Simultaneously, the optimized internal space layout, achieved through space-saving spacing, avoids signal interference, ensuring the overall system stability and reliability. This design not only enhances the user experience but also provides a more efficient and reliable storage expansion solution for mini PCs.

[0046] In one embodiment, please refer to Figure 3 , Figure 4 and Figure 5 The extension bracket has protective pads 50 around its perimeter to protect the computer host.

[0047] Protective pads 50 are cushioning components installed around the inside of the expansion bracket. They are typically made of soft, elastic materials such as silicone, rubber, or high-density foam. Their main function is to provide physical cushioning when the computer case is installed in the expansion bracket, absorbing external impacts and preventing damage from collisions or vibrations. The surface of the protective pads 50 is usually designed with anti-slip textures to ensure the computer case is stably placed within the installation space and to prevent displacement due to bracket movement or shaking.

[0048] When using the expansion stand, the computer host is placed within the stand's mounting space. At this time, the protective pads 50 fit snugly around the host, providing cushioning and stability. When the expansion stand is subjected to external impacts or vibrations, the protective pads 50 absorb the impact force, preventing the shock from being directly transmitted to the computer host, thus avoiding damage to the host's casing or internal components.

[0049] In this embodiment, the MiniPro hard drive expansion bracket provides reliable physical protection for the computer host by setting protective pads 50 around the expansion bracket. The soft material of the protective pads 50 can effectively absorb external impacts, preventing the computer host from being damaged by collisions or vibrations. At the same time, its anti-slip textured design ensures that the host is placed stably in the installation space, avoiding displacement due to the movement of the bracket.

[0050] In one embodiment, please refer to Figure 3 , Figure 4 and Figure 5 The housing 10 has an inspection opening on one side, and the housing 10 is detachably connected to a face cover 60, which is used to close the inspection opening.

[0051] The access opening is a pre-reserved opening area on the housing 10, mainly used to facilitate users to inspect, maintain, or replace the components inside the expansion bracket (such as the motherboard 20, solid-state drive 40, expansion interface 30, etc.). The access opening is designed with ease of operation in mind, and usually has enough space so that users can easily access the internal components.

[0052] The faceplate 60 is a component used to close the access opening and is detachably connected to the housing 10. The faceplate 60 is designed to ensure that the access opening can be tightly closed during normal use, thereby protecting internal components from external factors such as dust and liquids, while maintaining the overall aesthetics of the extension bracket. The faceplate 60 is typically made of the same or matching material as the housing 10 to ensure structural strength and visual consistency.

[0053] In the design of the expansion bracket, the access opening on one side of the housing 10 provides users with a channel for maintenance and replacement of internal components. When operation of internal components is required, users can easily remove the front cover 60 to access components such as the motherboard 20, solid-state drive 40, and expansion interface 30 through the access opening. After maintenance or replacement, users can reinstall the front cover 60, tightly connecting it to the housing 10 to close the access opening. This detachable connection method not only facilitates user operation but also ensures that internal components are well protected during normal use.

[0054] With an access opening on one side of the housing 10 and a removable cover 60, the MiniPro hard drive expansion bracket provides users with an efficient and convenient maintenance solution. The access opening design allows users easy access to internal components for inspection, maintenance, or replacement without disassembling the entire bracket, significantly improving maintenance efficiency. Meanwhile, the removable cover 60 ensures that the access opening can be tightly sealed during normal use, protecting internal components from external dust, liquids, and other contaminants, thus extending component lifespan.

[0055] In one embodiment, please refer to Figure 3 , Figure 4 and Figure 5 The face cover 60 is hinged to one side of the housing 10, and a buckle is provided on the other side of the face cover 60. The housing 10 is also provided with a buckle corresponding to the buckle so that the housing 10 and the face cover 60 are locked together.

[0056] A hinge is a connection method between the cover 60 and the housing 10. By setting a hinge on one side of the cover 60 and the housing 10, the cover 60 can rotate around the hinge axis, thereby realizing the function of opening and closing the access opening. The hinge design not only facilitates user operation but also ensures a tight connection between the cover 60 and the housing 10, preventing the cover 60 from accidentally falling off due to external forces. A snap-fit ​​is a locking device on the other side of the cover 60, used to fix the cover 60 to the housing 10. The housing 10 has a corresponding latch. When the cover 60 is closed, the snap-fit ​​and the latch engage to form a stable locking structure. This design allows for quick installation and removal of the cover 60 without additional tools or screws, while ensuring that the cover 60 will not loosen or open accidentally during normal use.

[0057] Through the hinged design of the faceplate 60 and the housing 10, as well as the locking mechanism of the snap-fit ​​and latch, the extension bracket enables quick and convenient maintenance. Users can easily open or close the faceplate 60 without using any tools, greatly improving maintenance efficiency. At the same time, the tight fit of the snap-fit ​​and latch ensures the stability of the faceplate 60 during normal use, effectively preventing external factors such as dust and liquids from damaging the internal components and extending the service life of the components.

[0058] In one embodiment, please refer to Figure 3 , Figure 4 and Figure 5 The top of the housing 10 is provided with a handle 70.

[0059] The top of the housing 10 features a handle 70. The handle 70 not only enhances the portability of the extension stand but also optimizes the user experience. The handle 70 typically employs an ergonomic curved design to ensure a comfortable grip when carrying it, reducing fatigue during prolonged use. Furthermore, the handle 70 is usually made of a soft and resilient material, such as rubber or silicone, further enhancing grip comfort.

[0060] The handle 70 is located at the center of the top of the housing 10, allowing users to grip it from any angle. This design makes it easier for users to lift the device when moving the extension stand, especially when the device is heavy or space is limited. The size and shape of the handle 70 are carefully designed to fit different users' hand shapes, ensuring ease of operation and stability.

[0061] By incorporating a handle 70 at the top of the housing 10, the portability and user experience of the extension stand are significantly enhanced. Users can easily move devices without worrying about them slipping or getting damaged. The handle 70 not only adds to the product's aesthetics but also reduces discomfort from prolonged gripping through its ergonomic shape and soft material. This design allows the extension stand to maintain high convenience and flexibility in various usage scenarios, providing significant assistance to users whether moving it in an office environment or adjusting device position in a home environment.

[0062] In one embodiment, please refer to Figure 3 , Figure 4 and Figure 5 The bottom of the housing 10 is provided with support feet 80.

[0063] The bottom of the housing 10 is provided with support feet 80. Support feet 80 are an important component of the extension bracket and are typically made of robust materials, such as metal or high-strength plastic, to ensure sufficient support strength. The design of support feet 80 not only provides stable support for the extension bracket but also further enhances the stability and safety of the equipment through its structure and material selection. The bottom of the support feet 80 is usually equipped with rubber or polyurethane pads, which have good anti-slip and shock-absorbing properties, effectively reducing vibrations during equipment operation while preventing the bracket from sliding on smooth surfaces.

[0064] The structural design of the support leg 80 takes into account multiple functional requirements. On the one hand, the height and shape of the support leg 80 have been optimized to adapt to different usage scenarios and placement surfaces, ensuring that the extension bracket remains stable under various conditions. On the other hand, the design of the support leg 80 also takes into account the heat dissipation requirements of the equipment, and through a reasonable spatial layout, avoids affecting the heat dissipation effect due to the contact between the support leg 80 and the ground.

[0065] In one embodiment, please refer to Figure 3 , Figure 4 and Figure 5 Multiple thermal pads or thermal grease are provided on the inner wall of the housing 10 in the area that contacts the computer host.

[0066] Thermal pads are silicone rubber-based heat-conducting materials, typically with added thermally conductive fillers (such as alumina and silicon nitride) to improve their thermal conductivity. They possess good flexibility, insulation, and natural adhesion, allowing them to adhere tightly between the computer case and its casing, filling gaps in irregular surfaces and achieving efficient heat conduction. The thickness of thermal pads can be selected according to requirements, typically between 0.5mm and 5mm. Thermal grease is a paste-like thermal interface material, mainly composed of silicone and thermally conductive fillers. Its primary function is to fill the tiny gaps between the computer case and heat dissipation components, reducing thermal resistance and thus improving heat dissipation efficiency. Thermal grease has low thermal resistance and good thermal conductivity, enabling rapid heat conduction.

[0067] In the design of the expansion bracket, multiple thermal pads or thermal grease are applied to the area where the inner wall of the housing 10 contacts the computer host. When the computer host is running and generates heat, the thermal pads or thermal grease can quickly absorb and conduct this heat, transferring it to the housing 10. Since the housing 10 typically has good heat dissipation performance, the heat is dissipated into the surrounding environment through the housing 10. This heat dissipation mechanism not only reduces the operating temperature of the computer host but also extends the lifespan of the device.

[0068] In one embodiment, please refer to Figure 3 , Figure 4 and Figure 5 The outer wall of the housing 10 is provided with multiple heat dissipation fins, which are arranged in an array at intervals.

[0069] Heat dissipation fins are an important heat dissipation component on the outer wall of the housing 10, and are usually made of materials with good thermal conductivity, such as aluminum alloy or copper. The main function of the fins is to increase the heat dissipation surface area, and to quickly dissipate heat into the environment through heat exchange with the surrounding air. Fins come in various shapes, commonly including straight fins, wavy fins, and diamond-shaped fins, each with its own advantages in heat dissipation efficiency and airflow characteristics.

[0070] In this embodiment, by providing multiple heat dissipation fins arranged in an array at intervals on the outer wall of the housing 10, the heat dissipation performance of the extended support is significantly improved. This design not only increases the heat dissipation surface area but also optimizes the airflow path and reduces thermal resistance. Compared with traditional finless heat dissipation designs, the heat dissipation efficiency can be improved by 30% to 80%. In addition, the optimized fin arrangement (such as staggered arrangement) can further reduce wind resistance and improve convective heat transfer efficiency.

[0071] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
