Description

Technical Field

[0001] The utility model relates to the technical field of power supply isolation covers, in particular to a power supply substrate cover. Background Art

[0002] The common power supply substrate has too large an area in contact with the outside air during use, making it easy for dust to accumulate on its surface. If a dust cover is directly added to the power supply board, it will affect the normal heat dissipation of the power supply board. Due to poor heat dissipation, the original components of the power supply board may be easily burned and damaged during use.

[0003] In order to solve the above problems, patent CN201921575460.1 discloses a power board dustproof isolation cover, which can shield the target power board from dust, while facilitating the heat dissipation of the original parts of the target power board to better meet the needs of use.

[0004] However, the following defects and shortcomings exist in its implementation: the isolation cover is used to prevent dust, but only a single heat sink is used for heat dissipation, and the heat dissipation effect is not ideal. At the same time, the isolation cover has poor anti-collision ability during use, and internal devices are easily damaged by squeezing and collision. Therefore, we propose a power substrate cover. Utility Model Content

[0005] In view of the deficiencies of the prior art, the utility model provides a power supply substrate cover to solve the existing problems.

[0006] To achieve the above purpose, the utility model is implemented through the following technical solutions: a power supply substrate cover, including a cover shell, a mounting seat is installed inside the cover shell, a power supply substrate is installed on the mounting seat, a heat dissipation hole is opened on the top of the cover shell, heat dissipation fins are fixedly installed on the shells at both ends of the cover shell, a scraper is arranged above the shell on the top of the cover shell, a slide rail is installed on the shell on one side of the cover shell, a slider is slidably clamped on the slide rail, the slider is fixedly connected to the scraper, rubber plates are fixedly installed on both sides of the mounting seat, two hinged rods are hinged on the rubber plate, one end of the hinged rod is hinged to the inner wall of the cover shell, a damping spring shock absorber is connected between the two hinged rods, and a drying box is installed on the inner wall of the cover shell.

[0015] 1. The power substrate cover of the present invention shields the power substrate from dust through a cover shell, and heat dissipation fins are installed on the cover shell, and heat dissipation holes are provided on the cover shell. The heat dissipation fins are conducive to heat conduction and heat dissipation of the cover shell, and air circulation and heat dissipation are convenient through the heat dissipation holes, and the heat dissipation effect is good. A slide rail is installed on the cover shell, and a slider is slidably engaged on the slide rail. A scraper is installed on the slider. Dust is easily accumulated in the heat dissipation hole after the heat dissipation hole has been used for a period of time, so that the scraper can be driven to slide on the upper surface of the cover shell by manually sliding the slider on the slide rail, and the heat dissipation hole can be cleaned by the scraper, so that the user can clean the heat dissipation hole in time, thereby improving the cleanliness of the heat dissipation hole, facilitating heat dissipation, and having strong practicality.

[0016] 2. A power substrate cover is provided with rubber plates installed on both sides of a mounting seat, hinged rods are hinged between the rubber plates and the cover shell, and a damping spring shock absorber is installed between the two hinged rods.
