Description

Technical Field

[0001] The utility model relates to the technical field of embedded computers, in particular to an embedded computer host structure. Background Art

[0002] Embedded computer hosts are usually used in embedded systems. Embedded systems refer to computer systems used in specific application fields. They usually focus on a single task or function. Embedded computers are highly integrated. They usually integrate the motherboard, CPU, memory, hard disk, cooling fan, etc. in a small box with a small size.

[0003] A dustproof plate is provided at the front end of the cooling fan of the embedded computer. The dustproof plate will be clogged with dust and other debris after long-term use, seriously affecting its heat dissipation. Since the embedded computer is small in size, there is no special cleaning device for the dustproof plate. The cleaning method is generally to disassemble it and then clean it. However, the dustproof plate used for heat dissipation, dust prevention and insect prevention in the existing embedded computer host is generally fixed with bolts. Since the embedded computer host is small in size, the bolts used are also small, which makes it difficult to disassemble and install the dustproof plate, and it is inconvenient to clean it. In addition, the existing embedded motor host has multiple connection jacks, and under normal use, the jacks are difficult to use completely, and the unused jacks are directly exposed to the air, and the dust in the external environment will cause pollution and damage to them.

[0004] To this end, we provide an embedded computer host structure to solve the above problems. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: an embedded computer host structure, including a chassis 1, a cooling fan 11 is arranged in the chassis 1, and the cooling fan 11 is used to dissipate heat and cool down the embedded computer. A dustproof plate 7 is arranged at the side end of the chassis 1, and the dustproof plate 7 is used to prevent external dust and insects from entering the chassis 1 to avoid damage to the electrical equipment in the chassis 1. The dustproof plate 7 needs to be cleaned after a long time to avoid being blocked by dust and causing heat dissipation difficulties. The four corners of the side end of the chassis 1 are fixedly connected with mounting blocks 2, and mounting holes 3 are opened in the mounting blocks 2. The mounting holes 3 are used to install the dustproof plate 7, and the mounting block 2 is fixedly connected with an extension The retractable rod 4 can be passively and freely retracted and extended. The tail end of the telescopic rod 4 is fixedly connected to a moving block 5, and the telescopic rod 4 is used to support the moving block 5. The side ends of the moving block 5 are respectively provided with a hypotenuse and a right-angled side. The upper end of the moving block 5 is fixedly connected to a No. 1 spring 6, and the No. 1 spring 6 provides kinetic energy for the movement of the moving block 5. The side end of the dustproof plate 7 is fixedly connected to a connecting rod 8, and the tail end of the connecting rod 8 is fixedly connected to a fixed trapezoidal block 9. The outer end of the connecting rod 8 is slidably connected to a moving trapezoidal block 10. The connecting rod 8, the fixed trapezoidal block 9, and the moving trapezoidal block 10 are inserted into the mounting hole 3. The hypotenuse of the moving block 5 can be slidably connected with the inclined surfaces of the fixed trapezoidal block 9 and the moving trapezoidal block 10.

[0026] A damper 18 is fixedly connected to the lower end of the chassis 1, and a pad 19 is fixedly connected to the lower end of the damper 18. A threaded hole is provided in the pad 19 for fixing the device through the pad 19. A No. 2 spring 20 is fixedly connected to the upper end of the pad 19. The No. 2 spring 20 is located at the outer end of the damper 18. The damper 18 cooperates with the No. 2 spring 20 to offset the kinetic energy transmitted to the device by external vibration, thereby avoiding damage to the device due to long-term vibration.

[0027] A jack is provided at the front end of the chassis 1 for data transmission. A protective cover shell 12 is provided at the front end of the chassis 1. The protective cover shell 12 is used to protect the jack. A connecting hole 13 is provided at the front end of the protective cover shell 12. The connecting hole 13 corresponds to the number and position of the jack. Slots 16 are provided at the upper and lower ends of the protective cover shell 12. The slots 16 are arranged corresponding to the connecting holes 13. A magnet bar 14 is fixedly connected to the protective cover shell 12. The magnet bar 14 is located in the middle section of the upper and lower connecting holes 13. The upper and lower ends of the magnet bar 14 are provided with card slots 15. A baffle 17 is inserted in the slot 16. The baffle 17 can be inserted in the card slot 15. The baffle 17 can be adsorbed by the magnet bar 14, so that the baffle 17 is inserted into the slot 16 so that its tail end is located in the card slot 15. The magnet bar 14 will adsorb the baffle 17, so that it is simply fixed.

[0028] Working principle: When installing the dustproof plate 7, insert the connecting rod 8 at its side end into the mounting hole 3 of the mounting block 2. The inclined surface of the fixed trapezoidal block 9 first contacts the inclined edge of the moving block 5 to push the moving block 5 away. When the fixed trapezoidal block 9 is separated from the moving block 5, the elastic potential energy of the No. 1 spring 6 is released to push the moving block 5 down, so that the right-angle side of the moving block 5 is located at the rear end of the fixed trapezoidal block 9. In this way, the connecting rod 8 cannot be directly pulled out of the mounting hole 3, thereby fixing the dustproof plate 7 and completing the installation.

[0029] When the dustproof plate 7 is removed, the connecting rod 8 is further inserted into the mounting hole 3, and the bevel of the movable block 5 will act on the movable trapezoidal block 10, so that the movable block 5 can be located on the bevel of the movable trapezoidal block 10. At this time, the connecting rod 8 is pulled outward, and the movable trapezoidal block 10 cannot move under the action of the movable block 5. The connecting rod 8 slides in the movable trapezoidal block 10 until the movable trapezoidal block 10 contacts the fixed trapezoidal block 9. At this time, the fixed trapezoidal block 9 will drive the movable trapezoidal block 10 to move, and at this time the movable block 5 moves on the bevel of the movable trapezoidal block 10, and directly crosses from the widest end of the movable trapezoidal block 10 to the bevel of the fixed trapezoidal block 9, so that the connecting rod 8, the fixed trapezoidal block 9, and the movable trapezoidal block 10 are detached from the mounting hole 3, and the removal of the dustproof plate 7 is completed;

[0030] The used jack is directly plugged into the jack through the connecting hole 13 by a plug, and for the unused jack, the baffle 17 is inserted into the corresponding slot 16, and its tail end will be located in the card slot 15 and attracted by the magnet bar 14, so it will not fall off easily. The baffle 17 can close the connecting hole 13 corresponding to the jack to protect it from being contaminated and damaged by dust.
