Description

Technical Field

[0002] Circuit boards are very common in people's lives. There are a large number of circuit boards in various electrical appliances. The programs of electrical appliances are controlled by circuit boards, which greatly facilitates people's daily life and travel. When installing some circuit boards that need to be installed naked, a circuit board protection frame is often required to protect the circuit board. The existing circuit board protection frames are generally of a frame structure, and the protection of the circuit board is realized by installing a protection board on the frame, so as to enclose the circuit board and prevent it from contacting the outside world. This structure affects the heat dissipation of the circuit board, thus affecting the normal use of the circuit board. At the same time, since the protection board is an integral structure, it is easy to be damaged when subjected to strong external impacts, so the entire protection board needs to be replaced, increasing the use cost of the protection frame and being inconvenient for the use of the protection frame.

[0015] (III) Advantageous Effects

[0016] Compared with the prior art, the present utility model provides a circuit board protection frame, which has the following advantageous effects:

[0017] 1. The utility model provides a protection structure to protect the top of the circuit board. Through the bolt cooperation of the connecting piece and the connecting groove, the protection plates are fixedly connected to each other and the protection frame. When the top of the circuit board is impacted, the impact force pushes the top plate to move along the mounting post, and the downward movement of the top plate compresses the spring. Thus, part of the impact is resisted by the elastic force of the spring itself. When the impact force is too large, the impact is resisted again through the deformation or breakage of the top plate and the protection plate. At the same time, by setting multiple protection structures, different protection structures protect impacts at different positions. Therefore, when one protection structure is damaged, other protection structures can continue to provide protection functions, and it is also convenient to replace the protection structures.

[0018] 2. The utility model is provided with heat dissipation holes on the protection plate, and the side frame is rotatably connected to the protection frame and the support frame through the rotational cooperation of the rotating column and the rotating hole. When the circuit board generates a large amount of heat during high-power operation, by rotating the side frame, a gap is generated between the side frames, thus facilitating the heat dissipation of the circuit board.

[0019] 3. The utility model is provided with airbags on the side frame. Through the airbags and the rotational connection of the side frame to the protection frame and the support frame, impacts on the side are resisted. At the same time, by setting the first buffer holes on the support post and the second buffer holes on the side frame, when the impact from above is too large, the first buffer holes and the second buffer holes are compressed and deformed to resist the larger impact, thus facilitating the protection of the circuit board.

[0037] In summary, when in use as a whole:

[0038] When installing the entire protection frame, the support frame 3 is connected to the circuit board by screwing in bolts through the cooperation of the mounting holes 18 opened on the extension piece 17 and the reserved spaces on the circuit board. The support column 2 is installed on the support frame 3 through the cooperation of the limit post 20 and the limit hole 19. The side frame 7 is installed on the support frame 3 through the cooperation of the rotating column 22 and the rotating hole 21. The protection frame 1 is installed on the support column 2 through the cooperation of the sleeve 9 and the top end of the support column 2. The connection between the protection frame 1 and the support column 2 is completed by inserting bolts into the threaded holes 10. The connection between the protection plates 4 and between the protection plates 4 and the protection frame 1 is fixed through the bolt cooperation of the connecting piece 13 and the connecting groove 12 to complete the installation of the entire mounting frame.

[0039] When an impact occurs at the top of the circuit board, the impact force pushes the top plate 6 to move along the mounting post 14, and the downward movement of the top plate 6 compresses the spring 5, thereby resisting part of the impact through the elastic force of the spring 5 itself. When the impact force is large, the impact force is resisted again through the deformation or breakage of the top plate 6 and the protection plate 4, thereby realizing the protection of the top of the circuit board. When the impact from above is too large, the first buffer hole 11 and the second buffer hole 23 are compressed and deformed to resist the large impact, thereby facilitating the protection of the circuit board.

[0040] When the circuit board needs to dissipate a large amount of heat, heat dissipation is carried out through the heat dissipation holes 16 opened on the protection plate 4 when the heat dissipation amount is small. The side frame 7 is rotatably connected to the protection frame 1 and the support frame 3 through the rotational cooperation of the rotating column 22 and the rotating hole 21. When the circuit board generates a large amount of heat during high-power operation, the side frame 7 is rotated to create a gap between the side frames 7, thereby facilitating the heat dissipation of the circuit board.
