Description

Technical Field

[0001] This invention relates to the field of computer security protection technology, specifically a security protection structure for computers. Background Technology

[0002] Computer security structures provide ventilation and heat dissipation protection for computer cases. As the housing for host hardware, the ventilation and heat dissipation performance of the computer case directly determines the operational stability and lifespan of core hardware such as the CPU, graphics card, and motherboard. Therefore, a ventilation and heat dissipation security structure is needed to protect the computer case. This computer security structure integrates airflow guidance, heat dissipation and ventilation, safety isolation, dust and foreign object prevention, and flame retardant protection. It is arranged at the air inlet, air outlet, and internal airflow area of ​​the case. Through layered protection, directional airflow, physical isolation, leakage protection, and a composite structure of flame retardant and noise reduction, it ensures efficient convection heat dissipation for heat-generating components such as the CPU, power supply, and graphics card inside the case, while preventing hands from reaching in, metal foreign objects from falling in, and dust and insects from entering. It also has electrical safety, fire prevention, cut prevention, and noise reduction functions.

[0003] Traditional computer security structures typically employ a combination of fixed openings, a single-layer dust filter, and a fixed air guide plate. Furthermore, both the cooling duct and the diameter of the ventilation openings are fixed. This fixed ventilation structure cannot adapt to the dynamic cooling requirements of the chassis. When the computer is idle or under light load, the hardware generates little heat, and conventional ventilation openings can meet the cooling needs. However, under high load, the hardware generates a surge in heat, and the fixed air duct is prone to airflow turbulence and insufficient ventilation, leading to heat accumulation and localized high temperatures inside the chassis. This can cause hardware throttling, stuttering, or even burnout.

[0004] Combining the above issues, we find that existing computer security protection structures are difficult to simultaneously avoid the problems mentioned above. Even if they can be solved, they require external tools, thus failing to achieve the desired effect. Therefore, we propose a computer security protection structure. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are: This invention, by setting up a ventilation and heat dissipation adjustment mechanism, utilizes a ventilation and heat dissipation box connected to one side of the computer chassis to facilitate ventilation and heat dissipation protection for the heat generated by the computer's core components within the chassis. Two sets of temperature sensors fixed to the inner wall of the computer chassis monitor the internal temperature in real time. A PLC controller processes and analyzes the temperature data detected by the temperature sensors, thereby controlling a dual-shaft synchronous motor fixed to the ventilation and heat dissipation box. This dual-shaft synchronous motor drives two rotating gears to rotate synchronously by the same number of angles.

Two fixed ventilation nets 203 are fixedly connected to the inner wall of the ventilation and heat dissipation box 202. Each fixed ventilation net 203 has a first ventilation hole 204 arranged at equal intervals on its left side. The upper surface of the ventilation and heat dissipation box 202 is fixedly connected to... There is a dual-shaft extension synchronous motor 208, which is a synchronous drive motor in which the rotor main shaft passes through the stator iron core and both ends of the rotating shaft extend out of the motor housing. It achieves constant synchronous speed operation by relying on the magnetic locking between the stator rotating magnetic field and the rotor excitation magnetic field.

The dual-shaft extension synchronous motor 208 drives two rotating gears 209 to rotate synchronously by the same number of turns. The two output ends of the dual-shaft extension synchronous motor 208 and the two rotating gears 209 are fixed by the fixing ring 210. At the connection point of 9, the connection stability between the two output ends of the dual-shaft extension synchronous motor 208 and the two rotating gears 209 is improved. Since a slidable movable ventilation plate 206 is set in the sliding groove 205 opened on the ventilation and heat dissipation box 202, and two fixed toothed belts 211 are fixed on one side of the movable ventilation plate 206, the movable ventilation plate 206 is driven to slide in the sliding groove 205 by the meshing between the two fixed toothed belts 211 and the two rotating gears 209. Furthermore, two fixed ventilation nets 203 are fixedly embedded on one side of the ventilation and heat dissipation box 202.

In turn, the PLC controller can control the rotation number and angle of the dual-shaft extension synchronous motor 208 according to the temperature inside the computer chassis body 1 to adapt to the dynamic heat dissipation requirements of the chassis.

The right side of each mounting plate 302 is fixedly connected to the left side of the protective cover 301. The protective cover 301 installed on the ventilation and heat dissipation box 202 is used to protect the two rotating gears 209 on the ventilation and heat dissipation box 202, thereby reducing the occurrence of safety accidents.

[0027] Please see Figure 1 , Figure 2 and Figure 3 The right ends of the two guide bars 308 are fixedly connected to a baffle 310. The upper surface of the baffle 310 is fixedly connected to the bottom surface of the ventilation and heat dissipation box 202. The right side of the limiting frame 312 is in contact with the left side of the baffle 310. The baffle 310 can block and limit the limiting frame 312 sliding in the guide groove 309, thereby improving the installation stability of the dust collection box 311.

[0028] Please see Figure 7 A sliding frame 4 is provided above the dust collection box 311. The sliding frame 4 is slidably connected to the inside of the ventilation and heat dissipation box 202. Two ventilation brackets 5 are fixedly connected to the inner wall of the sliding frame 4. The sliding frame 4 slides inside the ventilation and heat dissipation box 202, and two ventilation brackets 5 are fixed inside the sliding frame 4, thereby facilitating the formation of the main structure of the security protection structure for the computer.

[0029] Please see Figure 7 Each ventilation bracket 5 has a ventilation motor 6 fixedly connected to its inner wall, and each ventilation motor 6 has a rotating fan blade 7 fixedly connected to its output end. By using the ventilation motor 6 fixed inside the ventilation bracket 5, the PLC controller controls the two ventilation motors 6 to output opposite rotational power, so that the rotating fan blade 7 can rotate in opposite directions, so that the ventilation heat dissipation box 202 can circulate in and out cooling air.

[0030] Please see Figure 7 A pull plate 8 is fixedly connected to the upper surface of the sliding frame 4.

[0032] The specific implementation of this embodiment is as follows: In use, first connect the ventilation motor 6 to the power supply. When the safety protection structure is needed to provide ventilation and heat dissipation safety protection for the computer case, first utilize the sliding frame 4 inside the ventilation heat dissipation box 202, and fix two ventilation brackets 5 inside the sliding frame 4, thereby facilitating the formation of the main structure of the safety protection structure for the computer. Utilize the ventilation motor 6 fixed inside the ventilation bracket 5, and use the PLC controller to control the two ventilation motors 6 to output opposite rotational power, thereby enabling the rotating fan blades 7 to rotate in opposite directions, so that the ventilation heat dissipation box 202 can circulate in and out cooling air. This is achieved by manually holding the pull plate. 8. To facilitate the sliding of the sliding frame 4 inside the ventilation and heat dissipation box 202, and to facilitate the maintenance of the main body of the ventilation structure, the main body of the ventilation structure is further facilitated by manually holding the pull handle 9, and the dust collection box 311 is easily pulled out and cleaned by manually fastening the pull buckle 10. The protective cover 301 installed on the ventilation and heat dissipation box 202 is used to protect the two rotating gears 209 on the ventilation and heat dissipation box 202, thereby reducing the occurrence of safety accidents. The fixing plate 303 and the first cleaning brush 304 are fixed on one side of the ventilation and heat dissipation box 202 by the mounting plate 302. When the dual-shaft extension synchronous motor 2 When the output rotation drives the movable ventilation plate 206 to slide within the sliding groove 205, the fixed first cleaning brush 304 contacts and cleans one side of the movable ventilation plate 206, facilitating the cleaning of dust inside the second ventilation hole 207 on one side of the movable ventilation plate 206. Since the movable cleaning frame 306 is fixed to one side of the movable ventilation plate 206 by two fixed rods 305, and the second cleaning brush 307 is fixed to one side of the movable cleaning frame 306, when the movable ventilation plate 206 slides and moves, carrying the second cleaning brush 307 up and down, the second cleaning brush 307 can contact one side of the ventilation and heat dissipation box 202 and the two fixed ventilation meshes 202.

The baffle 310 can block and limit the limiting frame 312 sliding in the guide groove 309, thereby improving the installation stability of the dust collection box 311.

[0033] Example 3: Specifically, the security protection structure used by this computer during operation / use: First, connect the temperature sensor 201 and the dual-shaft extension synchronous motor 208 to the power supply. When this safety protection structure is needed for ventilation and heat dissipation protection of the computer chassis, the ventilation and heat dissipation box 202 connected to one side of the computer chassis body 1 is used to facilitate ventilation and heat dissipation protection of the heat generated by the computer core components inside the computer chassis body 1. Two sets of temperature sensors 201 fixed to the inner wall of the computer chassis body 1 are used to detect the temperature inside the computer chassis body 1 in real time. The PLC controller processes and analyzes the temperature data detected by the temperature sensors 201, and then controls the dual-shaft extension synchronous motor 208 fixed on the ventilation and heat dissipation box 202 through the PLC controller. Synchronous motor 208 drives two rotating gears 209 to rotate synchronously by the same number of turns. A fixing ring 210 is used to fix the connection points between the two output ends of the dual-shaft extension synchronous motor 208 and the two rotating gears 209, thereby improving the connection stability between the two output ends of the dual-shaft extension synchronous motor 208 and the two rotating gears 209. A slidable movable ventilation plate 206 is installed within a sliding groove 205 on the ventilation and heat dissipation box 202. Two fixed toothed belts 211 are fixed to one side of the movable ventilation plate 206. Through the meshing between the two fixed toothed belts 211 and the two rotating gears 209, the rotating gears 209 drive the movable ventilation plate 206 to slide within the sliding groove 205, thus facilitating ventilation and heat dissipation. Two fixed ventilation meshes 203 are fixedly embedded on one side of the box 202. Through the cooperation of the two fixed ventilation meshes 203 and the movable ventilation plate 206, the first ventilation hole 204 and the second ventilation hole 207 are connected and overlapped, thereby adjusting the ventilation hole area of ​​the computer's safety protection structure. This allows the PLC controller to control the rotation angle and number of revolutions of the dual-shaft synchronous motor 208 based on the temperature inside the computer chassis 1, adapting to the dynamic heat dissipation requirements of the chassis. In use, the ventilation motor 6 is first connected to the power supply. When this safety protection structure is needed for ventilation and heat dissipation safety protection of the computer chassis, a sliding frame 4 is slidably mounted inside the ventilation and heat dissipation box 202, and two ventilation brackets 5 are fixed within the sliding frame 4. This facilitates the construction of the main structure of the computer's security protection structure. The ventilation motor 6, fixed within the ventilation bracket 5, is controlled by a PLC controller to output opposite rotational power from two ventilation motors 6, causing the fan blades 7 to rotate in opposite directions. This allows for the flow of cooling air into and out of the ventilation and heat dissipation box 202. Manually holding the pull plate 8 allows the sliding frame 4 to slide within the ventilation and heat dissipation box 202, facilitating maintenance of the main ventilation structure. Manually holding the pull handle 9 further facilitates maintenance, and manually engaging the pull buckle 10 allows for the removal and cleaning of the dust collection box 311. A protective cover 301 is installed on the ventilation and heat dissipation box 202.To facilitate protection of the two rotating gears 209 on the ventilation and heat dissipation box 202 and reduce the occurrence of safety accidents, a fixing plate 303 and a first cleaning brush 304 are fixed on one side of the ventilation and heat dissipation box 202 by a mounting plate 302. When the dual-shaft extension synchronous motor 208 outputs rotation to drive the moving ventilation plate 206 to slide in the sliding groove 205, the fixed first cleaning brush 304 will contact and clean one side of the moving ventilation plate 206, facilitating the cleaning of dust in the second ventilation hole 207 on one side of the moving ventilation plate 206. Since the moving cleaning frame 306 is fixed on one side of the moving ventilation plate 206 by two fixing rods 305, and the second cleaning brush 307 is fixed on one side of the moving cleaning frame 306, the moving ventilation plate 206 can slide and move to carry the dust. When the second cleaning brush 307 is raised and lowered, it can contact one side of the ventilation and heat dissipation box 202 and one side of the two fixed ventilation nets 203, thus facilitating the cleaning of dust on one side of the fixed ventilation nets 203 and in the multiple first ventilation holes 204. Two guide strips 308 are fixed below the ventilation and heat dissipation box 202, and guide grooves 309 are provided on one side of the guide strips 308. This allows the limiting frame 312 fixed on the dust collection box 311 to slide within the two guide grooves 309, facilitating the installation of the dust collection box 311 below the ventilation and heat dissipation box 202 for automatic collection and processing of the cleaned dust. A baffle 310 can block and limit the sliding of the limiting frame 312 within the guide grooves 309, thereby improving the installation stability of the dust collection box 311.
