Description

Technical Field

[0001] This utility model relates to the field of mini PC casings, and in particular to a casing structure for a mini PC. Background Technology

[0002] In the field of computer hardware, mini PCs are widely used in various scenarios such as office work, home entertainment, and industrial control due to their advantages of small size, low space occupation, and high portability. As a crucial component of a mini PC, the casing not only needs to provide stable mounting support for the internal motherboard, processor, memory, and other core hardware, preventing damage from external impacts, but also needs to balance lightweight structure and practical appearance to adapt to the diverse usage needs of mini PCs. Currently, most mini PC casings on the market are made of plastic or aluminum alloy, manufactured through unibody molding or splicing processes, resulting in a relatively simple overall structure, primarily focusing on hardware protection and basic aesthetic design.

[0003] To address the heat buildup issue generated by the core hardware during mini PC operation, existing mini PC casings typically feature honeycomb ventilation holes on the sides or rear. These holes, with their dense, porous structure, accelerate the convection and exchange of hot internal air with cool external air, achieving efficient heat dissipation and ensuring stable operation of the mini PC over extended periods. However, this cooling structure has a significant drawback: when the mini PC is powered off and not in use, the ventilation holes are exposed, and the internal cooling fan is not operating. Consequently, there is virtually no airflow through the honeycomb ventilation holes, making it easy for airborne dust to accumulate within the holes due to gravity and electrostatic attraction. Over time, this dust can clog the effective ventilation channels, significantly reducing cooling efficiency upon the next startup, leading to overheating and performance degradation. Furthermore, dust entering the device and adhering to the circuit boards can increase the risk of short circuits and malfunctions, ultimately affecting the mini PC's lifespan. Utility Model Content

[0004] The main objective of this invention is to provide a shell structure for a mini PC that can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A mini PC casing structure includes a mini PC casing body, an auxiliary protective casing movably fitted onto the mini PC casing body, and an elastic support structure installed on the inner wall of the auxiliary protective casing at the lower end of the mini PC casing body. The elastic support structure consists of a base plate, a conical spring, and a top plate. The conical spring is fixedly installed on the upper end of the base plate, and the top plate is fixedly installed on the upper end of the conical spring. Four limiting components are symmetrically fixedly installed at the left and right ends of the auxiliary protective casing. Each limiting component consists of a U-shaped frame and a fixing spring. The fixing spring is fixedly installed on the inner wall of one side of the U-shaped frame, and a fixing component is installed on each of the two limiting components on the same side. Each fixing component consists of a rectangular frame, a spring pressure plate, and a fixing rod. There are two spring pressure plates symmetrically fixedly installed at one end of the rectangular frame, and the fixing rod is fixedly installed at the inner end of the rectangular frame. The fixing rod passes inward through the auxiliary protective casing and inserts into the mini PC casing body.

[0006] Preferably, the mini PC shell body has heat dissipation honeycomb holes at both the left and right ends, and four positioning slots are symmetrically provided at the left and right ends of the mini PC shell body and on the upper and lower sides of the heat dissipation honeycomb holes.

[0007] Preferably, two through slots are symmetrically formed on the front and rear walls of the auxiliary protective shell, and two through slots are symmetrically formed on the upper part of the left and right walls of the auxiliary protective shell.

[0008] Preferably, the bottom plate of the elastic support structure is fixedly installed on the lower inner wall of the auxiliary protective shell, and the top plate is in close contact with the lower end of the mini PC shell body.

[0009] Preferably, the four limiting components are located on the front and rear sides of the two through slots respectively, and the U-shaped frame is fixedly installed on the end face of the auxiliary protective shell.

[0010] Preferably, the rectangular frame on the fixing component is movably installed between two limiting components on the same side, the spring pressure plate is movably installed inside the U-shaped frame, and the spring pressure plate is located inside the fixing spring, and the fixing rod passes inward through the through groove and is inserted into the positioning slot.

[0011] Compared with the prior art, the present invention has the following beneficial effects: By adding an auxiliary protective shell to the main body of the mini PC, when the mini PC is not in use, the auxiliary protective shell can shield the heat dissipation honeycomb holes on the side of the mini PC main body, preventing dust from entering the device or clogging the channels. This effectively solves the problem of dust accumulation caused by exposed heat dissipation holes when the mini PC is not in use, ensuring heat dissipation efficiency and hardware stability after the device is started. At the same time, the auxiliary protective shell also provides additional protection for the main body of the mini PC, reducing the risk of damage to the internal hardware from external impacts. The auxiliary protective shell is equipped with an elastic support structure consisting of a base plate, a conical spring, and a top plate, as well as a limiting component consisting of a U-shaped frame and a fixed spring. The limiting component is equipped with... The fixing assembly, consisting of a rectangular frame, spring pressure plate, and fixing rod, allows the mini PC casing to be pressed down when the mini PC is off and not in use, so that it is completely inside the auxiliary protective shell. At this time, the limiting component, together with the fixing assembly and the positioning slot on the mini PC casing, can stably fix the mini PC casing inside the auxiliary protective shell. When the mini PC is turned on and in use, pulling the fixing assembly outward causes the fixing rod to move out of the positioning slot. At this time, the elastic support structure can automatically push the mini PC casing upward, thereby exposing the honeycomb holes of the mini PC casing to the outside, ensuring that the heat dissipation function can be properly performed. The overall structural design takes into account both dust protection and heat dissipation requirements, is easy to operate, and effectively improves the practicality and functionality of the mini PC casing.

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] Please see Figure 1 - Figure 5As shown, a mini PC shell structure includes a mini PC shell body 1, an auxiliary protective shell 2 movably fitted onto the mini PC shell body 1, and an elastic support structure 3 installed on the inner wall of the auxiliary protective shell 2 and at the lower end of the mini PC shell body 1. The elastic support structure 3 consists of a base plate 10, a conical spring 11, and a top plate 12. The conical spring 11 is fixedly installed on the upper end of the base plate 10, and the top plate 12 is fixedly installed on the upper end of the conical spring 11. Four limiting components 4 are symmetrically fixedly installed on the left and right ends of the auxiliary protective shell 2. The limiting components 4 consist of a U-shaped frame 13 and a fixing spring 14. The fixing spring 14 is fixedly installed on the inner wall of one side of the U-shaped frame 13, and the two on the same side are fixedly installed on the inner wall of the U-shaped frame 13. A fixing component 5 is installed on the limiting component 4. The fixing component 5 consists of a rectangular frame 15, spring pressure plates 16, and fixing rods 17. There are two spring pressure plates 16, which are symmetrically fixedly installed at one end of the rectangular frame 15. The fixing rods 17 are fixedly installed at the inner end of the rectangular frame 15. At the same time, the fixing rods 17 pass inward through the auxiliary protective shell 2 and are inserted into the mini PC shell body 1. By covering the mini PC shell body 1 with the auxiliary protective shell 2, when the mini PC is not in use, the auxiliary protective shell 2 can shield the heat dissipation honeycomb holes 6 on the side of the mini PC shell body 1, preventing dust in the air from entering the device or clogging the channels through the heat dissipation honeycomb holes 6, effectively solving the problem. When the mini PC is not in use, the dust accumulation caused by the exposed ventilation holes on the mini PC casing is addressed. This design ensures efficient heat dissipation and stable hardware operation after the device is started. Simultaneously, the auxiliary protective casing 2 provides additional protection for the main body of the mini PC casing 1, reducing the risk of damage to the internal hardware from external impacts. By incorporating an elastic support structure 3 (comprising a base plate 10, a conical spring 11, and a top plate 12) and a limiting component 4 (comprising a U-shaped frame 13 and a fixing spring 14) on the auxiliary protective casing 2, and a fixing component 5 (comprising a rectangular frame 15, a spring pressure plate 16, and a fixing rod 17) on the limiting component 4, the mini PC casing can be closed when the mini PC is powered off and not in use. When the main body 1 is pressed down, it is completely inside the auxiliary protective shell 2. At this time, the limiting component 4, together with the fixing component 5 and the positioning slot 7 opened on the mini PC shell main body 1, can stably fix the mini PC shell main body 1 inside the auxiliary protective shell 2. When the mini PC is turned on, the fixing component 5 is pulled outward, so that the fixing rod 17 is moved out of the positioning slot 7. At this time, the elastic support structure 3 can automatically push the mini PC shell main body 1 upward, thereby exposing the honeycomb holes of the mini PC shell main body 1 to the outside, ensuring that the heat dissipation function works normally. The overall structural design takes into account both dust protection and heat dissipation requirements, is easy to operate, and effectively improves the practicality and functionality of the mini PC shell.

[0016] Specifically, the mini PC shell body 1 has heat dissipation honeycomb holes 6 at both ends. Four positioning slots 7 are symmetrically provided at both ends of the mini PC shell body 1 and on the upper and lower sides of the heat dissipation honeycomb holes 6. Two through slots 8 are symmetrically provided on the front and rear walls of the auxiliary protective shell 2. Two through slots 9 are symmetrically provided on the upper part of the left and right walls of the auxiliary protective shell 2. The bottom plate 10 on the elastic support structure 3 is fixedly installed on the lower inner wall of the auxiliary protective shell 2. The top plate 12 is tightly attached to the lower end of the mini PC shell body 1. Four limiting components 4 are located on the front and rear sides of the two through slots 9 respectively. A U-shaped frame 13 is fixedly installed on the end face of the auxiliary protective shell 2. A rectangular frame 15 on the fixing component 5 is movably installed between the two limiting components 4 on the same side. A spring pressure plate 16 is movably installed inside the U-shaped frame 13, and the spring pressure plate 16 is located inside the fixing spring 14. A fixing rod 17 passes inward through the through slot 9 and is inserted into the positioning slot 7. When the mini PC needs to be used, the relative positions of the mini PC shell body 1 and the auxiliary protective shell 2 need to be adjusted. Figure 2 The status shown has changed to Figure 1 In the state shown, the rectangular frame 15 of the two fixing components 5 is pulled outward first. The rectangular frame 15 drives the spring pressure plate 16 to move within the U-shaped frame 13 of the limiting component 4 and presses the fixing spring 14. At the same time, the fixing rod 17 at the inner end of the rectangular frame 15 moves with the rectangular frame 15 and moves out of the positioning slot 7 on the mini PC shell body 1. At this time, the conical spring 11 on the elastic support structure 3 is no longer compressed and returns to its original position. The conical spring 11 pushes the top plate 12 to move upward, and the top plate 12 drives the mini PC shell body 1 to move upward until... The heat dissipation honeycomb holes 6 at both ends of the mini PC casing 1 are fully exposed on the outside of the auxiliary protective casing 2. At this time, the fixing rod 17 will align with the positioning slot 7 below. Then the rectangular frame 15 is released. At this time, the fixing spring 14 pushes the spring pressure plate 16 and the rectangular frame 15 to reset. The fixing rod 17 will be inserted into the positioning slot 7 below, thereby fixing the mini PC casing 1 in the current position. At this time, the mini PC can be turned on and used normally. The through slots 8 on the front and rear sides of the auxiliary protective casing 2 can ensure that the interfaces and other components of the mini PC are exposed and used normally.

[0017] Furthermore, after the mini PC is shut down and used, the relative positions of the mini PC main body 1 and the auxiliary protective shell 2 need to be changed from... Figure 1 The status shown has changed to Figure 2In the indicated state, when the mini PC shell body 1 is pressed down directly, the upper end face of the fixing rod 17 is in an arc state. When the mini PC shell body 1 is pressed down, the mini PC shell body 1 will push the fixing rod 17 on the fixing component 5 to move outward, so that the fixing rod 17 moves out of the positioning slot 7 below. When the fixing rod 17 moves outward, it will drive the rectangular frame 15 to move synchronously. The rectangular frame 15 will further drive the spring pressure plates 16 at both ends to slide within the U-shaped frame 13 of the limiting component 4, and compress the fixing spring 14 within the U-shaped frame 13, so that the fixing spring 14 is in a compressed state. As the mini PC shell body 1 is pressed down continuously, the mini PC shell body 1 will move outward. The lower end of the body 1 continuously compresses the top plate 12 of the elastic support structure 3. After being subjected to force, the top plate 12 compresses the conical spring 11 downwards until the mini PC shell body 1 is completely retracted into the auxiliary protective shell 2. At this time, the heat dissipation honeycomb hole 6 on the side of the mini PC shell body 1 is completely blocked by the auxiliary protective shell 2, and the positioning slot 7 above will be aligned with the fixing rod 17. Therefore, the fixing spring 14 will push the rectangular frame 15 and the fixing rod 17 to reset, so that the fixing rod 17 is inserted into the positioning slot 7 above, thereby stably fixing the mini PC shell body 1 in the auxiliary protective shell 2, completing the protection of the mini PC shell body 1 and the heat dissipation honeycomb hole 6.

[0018] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
