Description

Technical Field

[0001] The present application relates to the field of industrial computers, and in particular to a fixing structure of an industrial computer. Background Art

[0002] Traditional industrial computer mounting structures typically use rigid connections to ensure stability and securement. This structure primarily connects the computer directly to the mounting base via screws, bolts, and other fasteners, aiming to provide a secure fixation. However, this type of mounting structure lacks shock absorption, and in environments with high vibration levels, it can easily damage the computer's internal components, impacting the performance and lifespan of the industrial computer. Therefore, traditional industrial computer mounting structures without shock absorption have significant limitations in certain specific application scenarios.

[0003] To address the impact of vibration on industrial computers, existing technologies have proposed a number of fixed structure solutions with shock-absorbing effects. These solutions typically absorb vibration by adding shock-absorbing materials, shock-absorbing gaskets, or elastic connectors to the fixed structure, reducing the degree of vibration transmission to the computer body. For example, rubber gaskets or spring devices are added between the fixed component and the mounting base to form a shock-absorbing system, thereby effectively reducing the impact of environmental vibration on the computer. This type of solution improves the shock resistance of industrial computers to a certain extent and is suitable for industrial scenarios with relatively complex vibration environments.

[0004] Although the existing shock-absorbing fixed structure solution has achieved the shock-absorbing effect to a certain extent, its design still has some defects. For example, the realization of the shock-absorbing effect mostly relies on a single shock-absorbing element, the shock-absorbing effect is limited, and it is difficult to adapt to complex vibration environments with multiple directions and frequencies. In addition, the existing shock-absorbing structure usually loses its effectiveness due to the aging of the shock-absorbing element after a period of use, resulting in a decrease in shock-absorbing performance. For industrial computer application scenarios that require higher shock-absorbing effects, these existing solutions still cannot fully meet the needs. Therefore, in these environments, fixed structure solutions for industrial computers with shock-absorbing effects are more inclined to be used to improve the reliability and durability of the equipment. How to achieve effective shockproofing of industrial computers is still a technical problem that needs to be solved urgently. Utility Model Content

[0033] The following is combined with Figure 1-4 , some embodiments of the present application are described in detail. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0034] An embodiment of the present application provides a fixing structure 100 for an industrial computer, comprising:

[0035] computer;

[0036] A fixing component 2, one end of which is fixedly connected to the computer and the other end of which is rotatably connected to the shock absorbing structure 3;

[0037] The shock-absorbing structure 3 includes a shock-absorbing arm group and a shock-absorbing device 5. The shock-absorbing arm group is formed by clamping the fixed component 2 in the horizontal direction with multiple steel plates. Through holes are opened at both ends of the shock-absorbing arm group, and locking nuts are provided on the through holes. The shock-absorbing arm group is rotatably connected to the fixed component 2 through multiple locking nuts. The shock-absorbing device 5 is arranged on the shock-absorbing arm.

[0038] Specifically, the industrial computer fixing structure includes a computer, a fixing component 2, and a shock-absorbing structure 3. One end of the fixing component 2 is fixedly connected to the computer, and the other end is connected to the shock-absorbing structure 3 through rotation. The shock-absorbing structure 3 includes a shock-absorbing arm group and a shock-absorbing device 5. The shock-absorbing arm group is composed of multiple steel plates that clamp the fixing component 2 in the horizontal direction. The shock-absorbing arm group has through holes at both ends and is rotationally connected to the fixing component 2 through locking nuts. The shock-absorbing device 5 is arranged on the shock-absorbing arm. This design provides a stable rotational connection method through the steel plates and locking nuts of the shock-absorbing arm group, allowing the shock-absorbing device 5 to effectively absorb and reduce vibrations from different directions, thereby improving the stability and durability of the industrial computer in a vibrating environment. In actual application, the actuation process includes the shock-absorbing arm group achieving a rotational connection with the fixing component 2 through the locking nut, and the shock-absorbing device 5 cushioning the vibration through elastic materials and a hydraulic system. It is suitable for industrial scenarios requiring high shock resistance, such as production lines or factory environments with strong mechanical vibrations, and can effectively protect the internal components of the computer from vibration damage.

[0039] In a specific example, the shock absorbing arm group includes a first shock absorbing arm 7 and a second shock absorbing arm 8, the first shock absorbing arm 7 and the second shock absorbing arm 8 are arranged in parallel in the vertical direction, and the first shock absorbing arm 7 and the second shock absorbing arm 8 are both rotatably connected to the fixing component 2.

[0040] Specifically, the structure of the shock-absorbing arm assembly is further refined, including a first shock-absorbing arm 7 and a second shock-absorbing arm 8, which are arranged in parallel along the vertical direction and are both rotatably connected to the fixed assembly 2. This structure optimizes the stability of the shock-absorbing arm assembly, enables the shock-absorbing device 5 to provide more balanced support in the event of multi-directional vibration, and enhances the seismic resistance of the fixed structure, making it suitable for industrial environments with complex vibration directions.

[0041] In a specific example, the shock absorbing device 5 includes an elastic member 9, a hydraulic cylinder 10 and a transmission structure 11. The hydraulic cylinder 10 is fixedly connected to the first shock absorbing arm 7. One end of the transmission structure 11 is inserted into the hydraulic cylinder 10, and the other end is fixedly connected to the second shock absorbing arm 8. The elastic member 9 is annularly arranged on the hydraulic cylinder 10 and the transmission structure 11, and one end abuts the hydraulic cylinder 10, and the other end abuts the transmission structure 11.

[0042] Specifically, the shock-absorbing device 5 includes an elastic member 9, a hydraulic cylinder 10, and a transmission structure 11. The hydraulic cylinder 10 is fixedly connected to the first shock-absorbing arm 7. The transmission structure 11 is plugged into the hydraulic cylinder 10 at one end and fixed to the second shock-absorbing arm 8 at the other end. The elastic member 9 surrounds the hydraulic cylinder 10 and the transmission structure 11, abutting against them respectively. This design, through the combination of the hydraulic cylinder 10 and the elastic member 9, provides a strong shock-absorbing effect in vibrating environments. Furthermore, through the adjustment of the transmission structure 11, it can adapt to vibrations of different frequencies and directions, improving the adaptability and stability of the overall shock-absorbing system, making it suitable for industrial equipment subjected to high vibration loads.

[0043] In a specific example, the transmission structure 11 includes a fixed part 12 and a transmission rod 13. One end of the fixed part 12 and the transmission rod 13 are inserted into the hydraulic cylinder 10, and the other end is threadedly connected to the fixed part 12. The fixed part 12 is provided with a threaded hole 14, and the second shock absorbing arm 8 is threadedly connected to the fixed part 12.

[0044] Specifically, the transmission structure 11 is further refined. The transmission structure 11 includes a fixed portion 12 and a transmission rod 13, wherein one end of the fixed portion 12 and the transmission rod 13 are inserted into the hydraulic cylinder 10, and the other end is connected to the fixed portion 12 through a thread. The fixed portion 12 is provided with a threaded hole 14, and the second shock-absorbing arm 8 is connected to the fixed portion 12 through a thread. This design provides a stable transmission and adjustment function through a threaded connection, so that the shock-absorbing device 5 can accurately adjust and optimize the shock-absorbing effect under different vibration environments, increase the adaptability and adjustment range of the shock-absorbing device 5, and thus improve the reliability and performance of the overall shock-absorbing system. The actuation process includes adjusting the length of the transmission rod 13 by rotating the threaded fixed portion 12, thereby changing the working state of the shock-absorbing device 5. It is suitable for industrial environments where the shock-absorbing effect needs to be precisely adjusted, such as production lines where equipment vibration changes frequently.

[0045] In a specific example, the shock absorbing device 5 includes a first shock absorbing device 15 and a second shock absorbing device 16, which are arranged in parallel and symmetrically along the horizontal direction. One side of the first shock absorbing arm 7 is threadedly connected to the upper end of the first shock absorbing device 15, and the other side is threadedly connected to the upper end of the second shock absorbing device 16. One side of the second shock absorbing arm 8 is threadedly connected to the lower end of the first shock absorbing device 15, and the other side is threadedly connected to the lower end of the second shock absorbing device 16.

[0046] Specifically, the design of the shock absorber 5 has been further expanded to include a first shock absorber 15 and a second shock absorber 16, which are symmetrically arranged along the horizontal direction. The first shock absorber 15 is threadedly connected to the upper end of the first shock absorber arm 7, and the second shock absorber 16 is threadedly connected to the upper end of the second shock absorber arm 8, forming a symmetrical shock absorber system. This symmetrical arrangement provides a more uniform shock absorption effect, effectively reducing the impact of vibration on industrial computers and enhancing the overall stability and seismic resistance of the shock absorption system. The actuation process involves adjusting the tightness of the shock absorber 5 through threads to ensure a uniform distribution of the shock absorption effect. This is suitable for industrial applications with complex vibration directions and high stability requirements, such as high-precision production equipment.

[0047] In a specific example, the fixing assembly 2 includes a computer bracket 17 , which is disposed at one end of the shock absorbing arm assembly and fixedly connected to the computer.

[0048] Specifically, the mounting assembly 2 includes a computer bracket 17, which is mounted at one end of the shock-absorbing arm assembly and securely connected to the computer. This design provides a stable mounting base through the computer bracket 17, ensuring the computer's secure fixation. The connection with the shock-absorbing structure 3 also enhances the stability of the overall system. The operation process involves the mounting assembly 2 firmly attaching the computer to the shock-absorbing structure 3, ensuring that the computer does not move in a vibrating environment. This makes it suitable for industrial scenarios requiring high stability, such as production workshops subject to high mechanical vibration.

[0049] In a specific example, the fixing assembly 2 includes a shock absorbing assembly bracket 18, and the shock absorbing assembly bracket 18 is located at one end of the shock absorbing arm assembly away from the computer bracket 17, and the shock absorbing assembly bracket 18 is rotatably connected to the shock absorbing assembly.

[0050] Specifically, the design of the fixed assembly 2 has been further expanded to include a shock-absorbing assembly bracket 18. This bracket is located at the end of the shock-absorbing arm assembly away from the computer bracket 17 and is pivotally connected to the shock-absorbing assembly. This design enhances the stability of the shock-absorbing assembly and, through the pivoting connection, improves the flexibility and adaptability of the shock-absorbing structure 3. The actuation process, including the pivoting connection of the shock-absorbing assembly bracket 18, allows for free adjustment of the shock-absorbing assembly, making it suitable for industrial environments requiring high flexibility and strong shock absorption, such as production lines where equipment vibrates frequently.

[0051] In a specific example, the fixing structure 100 of the industrial computer includes a suction cup structure 19 , which is disposed at the bottom of the shock-absorbing bracket and is rotatably connected to the shock-absorbing bracket.

[0052] Specifically, the mounting structure has been further expanded to include a suction cup structure 19, located at the bottom of the shock-absorbing bracket and pivotally connected to it. This design, through the suction cup structure 19, provides additional attachment support, enhancing the mounting effect in vibrating environments and improving the adaptability of the shock-absorbing structure 3 through the pivoting connection. The actuation process utilizes the adhesion of the suction cup structure 19 to secure the shock-absorbing bracket to a flat surface, while allowing for minor adjustments to accommodate vibration variations. This makes it suitable for applications requiring strong adhesion and stability, such as when the bottom of a device is attached to a vibrating surface.

[0053] In a specific example, an adjusting nut 20 is provided on the suction cup structure 19 . The adjusting nut 20 is provided on the suction cup structure 19 , and one end of the adjusting nut 20 passes through the suction cup structure 19 and is threadedly connected to the shock absorbing bracket.

[0054] Specifically, the suction cup structure 19 is further refined, featuring an adjustment nut 20. This nut is attached to the suction cup structure 19, one end of which penetrates the structure and is threadedly connected to the shock-absorbing bracket. This design, through the adjustment nut 20, provides flexible fixation and adjustment capabilities, allowing the adhesion and stability of the suction cup structure 19 to be adjusted according to actual needs. The actuation process involves rotating the adjustment nut 20 to adjust the tightness of the connection between the suction cup structure 19 and the shock-absorbing bracket, thereby optimizing the suction effect. This is suitable for industrial applications with varying vibration intensities and fixation requirements, such as equipment that requires adjustment of suction force based on vibration intensity.

[0055] In a specific example, the computer stand 17 includes a rotating stand 21 and a fixed stand 22. In the vertical direction, the rotating stand 21 is arranged at the upper end of the fixed stand 22. One end of the fixed stand 22 is bolted to the shock absorbing arm group, and the other end is bolted to the rotating stand 21.

[0056] Specifically, the design of the computer stand 17 has been further expanded to include a rotating bracket 21 and a fixed bracket 22. The rotating bracket 21 is disposed at the upper end of the fixed bracket 22. One end of the fixed bracket 22 is bolted to the shock-absorbing arm assembly, and the other end is bolted to the rotating bracket 21. This design provides additional flexibility and stability through the combination of the rotating bracket 21 and the fixed bracket 22, which can improve the fixing effect in a vibrating environment while adapting to different installation and adjustment requirements. The actuation process includes the rotation and adjustment of the computer stand 17 through the provision of the rotating bracket 21, ensuring that it can flexibly respond to changes in a vibrating environment. It is suitable for industrial scenarios that require flexible adjustment and high stability, such as applications where the fixed structure needs to be adjusted according to the position of the equipment.

[0057] The above is only an implementation method of the present application. It should be pointed out that for ordinary technicians in this field, improvements can be made without departing from the creative concept of the present application, but these all fall within the scope of protection of the present application.
