Description

Technical Field

[0001] This utility model relates to the field of lightweight hardware structure technology, specifically a lightweight hardware structure based on FPGA. Background Technology

[0002] An FPGA is a programmable logic device whose core feature is "field-programmable"—users can define the function of its internal circuitry by programming it after the chip leaves the factory, without relying on fixed hardware wiring like an ASIC (Application-Specific Integrated Circuit). FPGA-based lightweight hardware architectures aim to meet functional requirements in specific scenarios with minimal resource overhead, power consumption, and size. The core is to achieve a "simplified yet efficient" design through resource optimization, functional specialization, and configurability trade-offs.

[0003] Chinese utility model patent CN210168365U discloses a circuit board with a protective shell, belonging to the field of circuit board technology. It includes two sets of retaining frames, with a circuit board body disposed inside each set of frames. Threaded holes are provided on the sides of the retaining frames, and studs are threaded into the inner sides of the threaded holes. A retaining post is connected to the side of the stud closest to the circuit board body. Retaining slots that mate with the retaining posts are provided on both sides of the circuit board body. A cavity is provided inside each retaining frame, and the cavity communicates with the threaded holes. This utility model allows for easy installation of the protective shell by pushing the circuit board body to the inside of the two sets of retaining frames, turning the handle to rotate the studs, and pushing the retaining posts through the interaction of the studs and threaded holes. The retaining posts in the cavity are then engaged with the retaining posts, facilitating the separation of the circuit board body from the protective shell.

[0004] However, this utility model can only protect a single circuit board during use, and cannot protect and install multiple circuit boards at the same time, which affects the practicality of the device and makes it inconvenient to transport. Therefore, a lightweight hardware structure based on FPGA is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a lightweight hardware structure based on FPGA, which has the advantage of being able to protect multiple circuit boards simultaneously. This solves the problem that existing protection structures can only protect a single circuit board and cannot protect multiple circuit boards at the same time, thus affecting the practicality of the device and making it inconvenient to transport.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lightweight hardware structure based on FPGA, including a protective box and a cover plate hinged to the top of the protective box, wherein an FPGA circuit board is disposed inside the protective box, and a protective structure capable of protecting the FPGA circuit board is disposed inside the protective box.

[0007] The protective structure includes a protective plate slidably connected inside the protective box. The upper surface of the protective plate has a mounting groove adapted to the FPGA circuit board. A support spring is fixedly connected inside the protective plate. One end of the support spring is fixedly connected to a limiting block extending to the top of the FPGA circuit board. A protective gasket that can protect the FPGA circuit board is fixedly connected inside the protective plate.

[0008] Furthermore, a sliding block is slidably connected to the upper surface of the protective plate, and a connecting block is fixedly connected between the sliding block and the limiting block. An active groove adapted to the connecting block is formed on the upper surface of the protective plate.

[0009] Furthermore, there are four protective plates, which are evenly distributed inside the protective box. The bottom of the top protective plate is fixedly connected to a positioning post that extends into the bottom protective plate.

[0010] Furthermore, a filling pad that abuts against the protective plate is fixedly connected to the inner bottom wall of the protective box, and a handle extending to the top of the protective box is rotatably connected to the outside of the protective box.

[0011] Furthermore, a return spring is fixedly connected inside the cover plate, and a connecting rod extending to the bottom of the cover plate is fixedly connected to the bottom end of the return spring. A pressing plate is fixedly connected to the end of the connecting rod away from the return spring.

[0012] Furthermore, the lower surface of the extrusion plate abuts against the upper surface of the protective plate, and the connection between the connecting rod and the cover plate is a sliding connection.

[0013] Furthermore, both the protective box and the cover are fixedly connected to the front of a buckle structure. There are two buckle structures, which are symmetrically distributed on the front of the protective box.

[0014] Compared with the prior art, this utility model provides a lightweight hardware structure based on FPGA, which has the following advantages:

[0015] 1. This lightweight hardware structure based on FPGA can protect the FPGA circuit board by setting a protective plate and protective gasket. By setting a support spring and a limit block, the FPGA circuit board can be limited to prevent it from shaking inside the protective plate. By setting a sliding block, the limit block can be moved to facilitate the removal of the FPGA circuit board. This achieves the effect of protecting multiple FPGA circuit boards at the same time.

[0016] 2. This lightweight hardware structure based on FPGA, by setting a reset spring and connecting rod, and by setting a squeezing plate, allows the squeezing plate to elastically displace. When the cover is closed, the squeezing plate can squeeze the protective plate, further preventing the protective plate from shaking inside the protective box, improving stability. It solves the problem that the existing protection structure can only protect a single circuit board and cannot protect multiple circuit boards at the same time, thus affecting the practicality of the device and making it inconvenient to transport.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 2This embodiment of a lightweight hardware structure based on FPGA includes a protective box 1 and a cover plate 2 hinged to the top of the protective box 1. An FPGA circuit board 3 is disposed inside the protective box 1. The protective box 1 is provided with a protective structure that can protect the FPGA circuit board 3. The protective structure includes a protective plate 4 slidably connected inside the protective box 1. The upper surface of the protective plate 4 is provided with a mounting groove adapted to the FPGA circuit board 3. A support spring 5 is fixedly connected inside the protective plate 4. One end of the support spring 5 is fixedly connected with a limiting block 6 extending to the top of the FPGA circuit board 3. A protective washer 7 that can protect the FPGA circuit board 3 is fixedly connected inside the protective plate 4.

[0024] Specifically, a sliding block 8 is slidably connected to the upper surface of the protective plate 4, and a connecting block is fixedly connected between the sliding block 8 and the limiting block 6. An active groove adapted to the connecting block is opened on the upper surface of the protective plate 4. There are four protective plates 4, which are evenly distributed inside the protective box 1. A positioning post 9 extending into the bottom of the bottom protective plate 4 is fixedly connected to the bottom of the top protective plate 4.

[0025] It should be noted that the FPGA circuit board 3 integrates an FPGA chip. The internal structure of the FPGA can be summarized as "programmable logic unit + interconnection resources + auxiliary modules".

[0026] It should be noted that by setting the protective plate 4 and the protective gasket 7, the FPGA circuit board 3 can be protected during installation. By setting the support spring 5 and the limiting block 6, the FPGA circuit board 3 can be limited to prevent it from shaking inside the protective plate 4. Furthermore, by setting the sliding block 8, the limiting block 6 can be moved to facilitate the removal of the FPGA circuit board 3.

[0027] Please see Figure 1 , Figure 3 and Figure 4 In this embodiment, a filling pad 10 that abuts against the protective plate 4 is fixedly connected to the inner bottom wall of the protective box 1. A handle 14 extending to the top of the protective box 1 is rotatably connected to the outside. A return spring 12 is fixedly connected inside the cover plate 2. A connecting rod 13 extending to the bottom of the cover plate 2 is fixedly connected to the bottom end of the return spring 12. A pressing plate 11 is fixedly connected to the end of the connecting rod 13 away from the return spring 12.

[0028] Specifically, the lower surface of the extrusion plate 11 abuts against the upper surface of the protective plate 4, and the connection between the connecting rod 13 and the cover plate 2 is a sliding connection.

[0029] It should be noted that by setting a reset spring 12 and a connecting rod 13, and by setting a pressing plate 11, the pressing plate 11 can be elastically displaced. Thus, when the cover plate 2 is closed, the pressing plate 11 can press the protective plate 4, further preventing the protective plate 4 from shaking inside the protective box 1 and improving stability.

[0030] Please see Figure 1 and Figure 4 In this embodiment, the front sides of both the protective box 1 and the cover plate 2 are fixedly connected with two buckle structures, which are symmetrically distributed on the front side of the protective box 1.

[0031] The working principle of the above embodiments is as follows:

[0032] First, the staff removes the protective plate 4 from inside the protective box 1, then moves the sliding block 8 outward. At this time, the FPGA circuit board 3 is placed in the mounting slot on the protective plate 4. Then, the sliding block 8 is released, and the limiting block 6 limits and fixes the FPGA circuit board 3. Then, the protective plate 4 is placed inside the protective box 1, and the cover plate 2 is closed.

[0033] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that can achieve its beneficial effects can be implemented.
