Description
Technical Field
[0001] This utility model relates to the field of computer host technology, and in particular to a computer host back cover with dustproof function. Background Technology
[0002] The computer case primarily protects the internal electronic components. It mainly consists of a back cover and a protective shell. Different materials used in the manufacturing of the computer case result in different performance characteristics. For example, a computer case made primarily of magnesium alloy has good support and pressure resistance. Chinese utility model patent, authorization announcement number "CN204242069", discloses a back cover with an automatic ventilation window function. This includes a back cover with ventilation windows, a temperature sensor, a controller, an upper support block, and a lower support block. The upper support block is fixed to the back cover directly above the ventilation windows, and the lower support block is fixed to the back cover directly below the ventilation windows. A vertically mounted linear guide rail and ball screw are provided between the upper and lower support blocks. Ventilation windows are mounted on the linear guide rail and ball screw, and these windows move vertically under the action of the linear guide rail and ball screw.
[0003] The above-mentioned technical solution has a simple and compact structure and low production cost. It automatically detects the temperature of various parts inside the computer host and controls the opening of the heat dissipation window through the controller, changing the heat dissipation of the computer host from heat dissipation through the heat dissipation hole to window heat dissipation. This allows the hot air inside the computer host to quickly circulate with the outside air, thus achieving rapid heat dissipation of the computer host. However, the above-mentioned technical solution still has certain defects. The back cover of the host with automatic window opening heat dissipation function mainly uses a ball screw to drive the movement of the heat dissipation window to open a gap, allowing the host fan to directly contact the outside air to accelerate the heat dissipation of the computer host. However, although this heat dissipation method improves the heat dissipation efficiency, it also increases the risk of external dust entering the host and damaging electronic components. Therefore, this utility model proposes a new solution. Utility Model Content

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.
[0031] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0032] Please see Figure 1-8 This utility model provides a technical solution: a computer host back cover with dustproof function, including a computer host back cover 2, a computer host body 1 disposed on the rear side of the computer host back cover 2, a dustproof component, the dustproof component being disposed on the computer host back cover 2, the dustproof component including a connecting frame 5, the connecting frame 5 being disposed on the front side of the computer host back cover 2, a connecting bracket 8 being fixedly connected to the front end of the connecting frame 5, a first dust cover 9 being fixedly connected to the front end of the connecting frame 5, a second sliding groove 12 being formed on the inner wall of the connecting bracket 8, and the inner wall of the second sliding groove 12 being... A dust cover connecting frame 11 is slidably connected. A second dust cover 10 is fixedly connected to the inner wall of the dust cover connecting frame 11. The connecting frame 8, the dust cover connecting frame 11, and the second slide groove 12 are all U-shaped. Two third slide grooves 16 are opened on the inner wall of the connecting frame 8. A limiting plate 13 is provided inside the connecting frame 8. The limiting plate 13 is slidably connected to the inner wall of the two third slide grooves 16. Two sealing blocks 15 are fixedly connected to the lower end of the limiting plate 13. Both sealing blocks 15 are slidably connected to the second dust cover 10 and the dust cover connecting frame 11.
[0033] The first dust cover 9 and the second dust cover 10 are designed primarily to prevent external dust from entering the computer case through the opening in the rear cover. Dust is one of the "killers" of computer hardware; it easily accumulates on the surface of hardware, affecting heat dissipation and potentially causing short circuits or damage. Therefore, the existence of the first dust cover 9 and the second dust cover 10 is of great significance for protecting computer hardware and extending its lifespan. The sliding connection between the dust cover connecting bracket 11 and the second sliding groove 12 makes the second dust cover 10 easy to disassemble and install. Both the connecting bracket 11 and the second sliding groove 12 are U-shaped, which effectively supports the lower end of the second dust cover 10 and improves its stability. This makes it convenient for users to clean and maintain the first dust cover 9 and the second dust cover 10. Since the second dust cover 10 is located on the side away from the computer host rear cover 2, the first dust cover 9 is still present during the disassembly and cleaning of the second dust cover 10 to protect the computer host body 1 from dust, thus improving the practicality and convenience of the computer host rear cover 2.
[0034] The limiting plate 13 slides inside the second mounting plate 14, facilitating the restriction of the position of the second dust cover 10 and the dust cover connecting bracket 11, improving the stability of the second dust cover 10 and the dust cover connecting bracket 11 during installation, and preventing the second dust cover 10 from loosening. As the first line of defense outside the chassis, the second dust cover 10 effectively blocks external dust, dirt, and other impurities from entering the chassis through the opening in the rear cover. The sealing block 15 facilitates the sealing of the gaps between the second dust cover 10, the dust cover connecting bracket 11, and the limiting plate 13, improving the sealing performance. The use of the sealing block 15 further enhances the dustproof effect of the second dust cover 10. By limiting the edge of the second dust cover 10, the existence of gaps is reduced. This sealing design not only prevents dust from seeping in from gaps but also improves the overall sealing performance of the chassis, helping to maintain a clean environment inside the chassis and further enhancing the dustproof effect.
[0035] By installing and removing the second dust cover 10, the resistance to air entering the computer host 1 can be adjusted, which facilitates the improvement of heat dissipation. When the first dust cover 9 is used alone, dust protection can also be carried out through the first dust cover 9, further improving the dust protection effect.
[0036] Both the first dust cover 9 and the second dust cover 10 are shell-shaped with a certain wall thickness.
[0037] The connecting frame 5 is fixedly connected to the top, bottom, left and right sides with the first mounting plate 6. The four first mounting plates 6 are fixed to the back cover 2 of the computer host with screws.
[0038] The first mounting plate 6 facilitates the fixing of the connecting frame 5 to the surface of the computer host's back cover 2, ensuring a seal between the first dust cover 9 and the computer host's back cover 2. This allows the first dust cover 9 to effectively prevent dust accumulation. The screw fixing ensures the first dust cover 9 is firmly attached to the computer host's back cover 2, preventing it from easily falling off or loosening even when the chassis is subjected to vibration or external impact. This stability is particularly important for computer equipment used for extended periods, preventing dust intrusion due to a loose first dust cover 9. The screws tightly securing the first dust cover 9 to the computer host's back cover 2 reduce gaps, improving the overall sealing of the chassis and preventing dust from seeping into the computer host 1, further protecting the cleanliness of the computer host 1's interior.
[0039] The left and right sides of the limiting plate 13 are fixedly connected with the second mounting plate 14, and the two second mounting plates 14 are fixed to the back cover 2 of the computer host by screws.
[0040] The second mounting plate 14 facilitates the positioning of the limiting plate 13, preventing it from loosening during use and affecting the sealing effect of the sealing block 15 on the second dust cover 10, the dust cover connecting bracket 11, and the limiting plate 13. This improves the stability of the limiting plate 13 and the second dust cover 10, and enhances the dustproof effect of the second dust cover 10. The second mounting plate 14 fixes the limiting plate 13 to the computer host back cover 2, allowing users to easily remove the dust covers for cleaning or maintenance when the inside of the first dust cover 9 and the second dust cover 10 is needed, without worrying about damaging the computer host body 1, the first dust cover 9, or the second dust cover 10 itself, thus improving the efficiency and convenience of maintenance.
[0041] The front side of the computer host body 1 is provided with a first sliding groove 3. The rear side of the computer host back cover 2 is fixedly connected with six first connecting blocks 4. The six first connecting blocks 4 are located at the upper and lower ends and the left end of the computer host back cover 2 respectively. The rear side of the computer host back cover 2 is fixedly connected with a second connecting block 7. The six first connecting blocks 4 and the second connecting block 7 are slidably connected with the first sliding groove 3. The computer host back cover 2 is slidably connected with the first sliding groove 3. The computer host body 1 and the computer host back cover 2 are fixed together by screws.
[0042] With the first sliding groove 3 and the first connecting block 4 in place, after removing the screws connecting the computer host back cover 2 to the computer host body 1, the computer host back cover 2 can be easily opened or closed by sliding the first sliding groove 3 inside the first connecting block 4. This is very convenient for users who need to frequently access the inside of the computer case for hardware upgrades, maintenance or cleaning. When the first sliding groove 3 is fully slid into the first connecting block 4 and locked in place, the second connecting block 7 also slides inside the first connecting block 4. The second connecting block 7 can provide additional sealing, which helps to prevent dust, dirt and other impurities from entering the inside of the computer host body 1, thereby protecting the hardware inside the computer host body 1 and improving the convenience of using the computer host back cover 2.
[0043] The first dust cover 9 has a cooling fan 17 installed inside, and the computer host body 1 has a heat dissipation hole on the right side.
[0044] The cooling fan 17 facilitates the drawing of external air from the first dust cover 9 and the second dust cover 10 into the computer host 1, thus promoting heat dissipation. Simultaneously, the cooling fan 17 accelerates airflow within the chassis, improving heat transfer efficiency and allowing hot air to escape through the ventilation holes on the right side of the computer host 1, thereby lowering hardware temperatures and ensuring normal computer operation.
[0045] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
