Description

Technical Field

[0001] This utility model relates to the field of power amplifier cover technology, specifically a power amplifier cover with strong protective properties. Background Technology

[0002] A power amplifier shroud (also known as a power amplifier protective cover, dust cover, or protective cover) is a physical device that covers the top of a power amplifier. Its primary purpose is to protect the internal components and circuit boards from damage caused by external factors such as dust, foreign objects, and liquid splashes. Its design aims to extend the amplifier's lifespan and ensure stable operation, which is especially important in harsh environments (such as outdoor performances and industrial sites).

[0003] An existing authorized publication number CN218071711U discloses an active speaker amplifier module, including an amplifier module motherboard and capacitors, heat sinks, regulators, left channel output interfaces, and right channel output interfaces fixedly mounted on the upper surface of the amplifier module motherboard. The active speaker amplifier module further includes: an edging portion that wraps around the outside of the edge of the amplifier module motherboard; a shielding cover that covers the top of the amplifier module motherboard; and a locking bolt for fixing the shielding cover, with the bolt's shank penetrating the amplifier module motherboard and extending to its lower surface. In this invention, the studs are connected to the locking bolts via elastic components, thus allowing the amplifier module motherboard to be elastically connected to the speaker enclosure, thereby reducing the probability of damage to the amplifier module due to vibration.

[0004] The aforementioned technical solutions may hinder heat dissipation, causing heat to accumulate inside the enclosure and potentially affecting internal electronic components. Furthermore, maintenance is inconvenient, requiring frequent disassembly using tools, reducing work efficiency and increasing the risk of operational errors. Therefore, we provide a highly protective amplifier enclosure. Utility Model Content

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a technical solution: such as Figures 1-4As shown, in this embodiment, a highly protective amplifier cover includes a housing 11. An upper cover body 12 is located on the top of the housing 11. Two fixing slots 13 are formed on one side of the upper cover body 12. A dustproof mesh 14 is installed in a slot on the top of the upper cover body 12. Two supports 15 are located inside the upper cover body 12, each support 15 has a motor 16 mounted on it, and each motor 16 has a cooling fan 17 on its top. A docking slot 113 is formed inside the housing 11. Pull rods 18 are installed in the two slots on one side of the housing 11. Springs 19 are installed on the outside of each pull rod 18. A fixing block 111 is provided at the end of each pull rod 18 near the docking slot 113. A sliding piece 110 is provided on the outside of each pull rod 18 near the fixing block 111. A handle 112 is provided at the end of each pull rod 18 away from the fixing block 111. The top of the housing 11 away from the handle 112 and the bottom of the upper cover body 12 away from the handle 112 are connected. One side is connected by a hinge. The bottom of the upper cover body 12 is connected to the docking groove 113. A dustproof net 14 is fixedly connected to the slot opened at the top of the upper cover body 12. The bracket 15 is fixedly connected to the inside of the upper cover body 12. The outside of the motor 16 is fixedly connected to the bracket 15. One end of the pull rod 18 is fixedly connected to one side of the handle 112. The end of the pull rod 18 away from the handle 112 passes through the slot opened on one side of the housing 11 and the inner ring of the spring 19 and is fixedly connected to one side of the fixing block 111. A sliding piece 110 is fixedly connected to the outside of the pull rod 18. One end of the spring 19 is fixedly connected to one side of the sliding piece 110. The other end of the spring 19 is fixedly connected to the inner wall of the slot opened in the housing 11 away from the fixing block 111. The outside of the sliding piece 110 is slidably connected to the inner wall of the slot opened in the housing 11. The fixing block 111 is engaged in the fixing groove 13. An amplifier module 31 is provided inside the housing 11. A sealing mechanism 2 is provided at the bottom of the upper cover body 12.

[0025] In this embodiment, to ensure the protective effect of the device when it is needed, a flip-top upper cover body 12 is provided on the upper part of the housing 11. When the staff needs to inspect and maintain the power amplifier module 31 inside the housing 11, they can pull the handle 112. Two pull rods 18 are connected to one side of the handle 112. The two pull rods 18 will be pulled synchronously, and the two fixing blocks 111 provided at the ends of the two pull rods 18 away from the handle 112 will disengage from their respective fixing grooves 13 and recess into the slots opened in the housing 11. The spring 19 will be squeezed by the movement of the sliding piece 110 in the groove. At this time, the upper cover body 12 The limit switch between the upper cover and the housing 11 will be released, allowing the staff to open the upper cover and inspect the power amplifier module 31 inside. When it is necessary to install the upper cover body 12, the handle 112 needs to be pulled to drive the two pull rods 18. After the upper cover body 12 is placed in the docking groove 113 on the top of the housing 11, the handle 112 is released. The spring 19 will release its elasticity and push the fixing block 111 to engage in the fixing groove 13. Thus, the upper cover body 12 will be fixedly installed with the housing 11. In addition, the two cooling fans 17 provided in the upper cover body 12 can provide effective heat dissipation for the equipment, preventing the heat accumulated in the housing 11 from affecting the power amplifier module 31.

[0026] like Figures 1-4 As shown, the sealing mechanism 2 includes a sealing gasket 21, which is fixedly connected to the bottom of the upper cover body 12. The bottom of the docking groove 113 is provided with a sealing groove 22, and the sealing gasket 21 is docked in the sealing groove 22.

[0027] In this embodiment, the sealing gasket 21 and the sealing groove 22 are tightly fitted together, which can effectively prevent external dust, fibers, liquids and other impurities from entering the device through the gap between the housing 11 and the upper cover body 12, thus protecting the power amplifier circuit board and components.

[0028] This utility model provides a highly protective power amplifier cover, the specific working principle of which is as follows:

[0029] During equipment use, to ensure its protective performance, the top of the housing 11 is equipped with a flip-top cover body 12. When the operator needs to inspect or maintain the power amplifier module 31 inside the housing 11, the operator holds the handle 112 and pulls it outward. The pull rods 18 connected to both sides of the handle 112 are pulled simultaneously. The end of the pull rod 18 is provided with a fixing block 111. When pulled, the fixing block 111 disengages from the corresponding fixing groove 13 of the housing 11 and recesses into the slot on the side of the housing 11. When the fixing block 111 moves, the sliding piece 110 linked with it compresses the spring 19. The spring 19 is compressed and shortened. As the fixing block 111 disengages, the limiting structure between the upper cover body 12 and the housing 11 is released, and the operator can easily flip open the upper cover. The interior of the exposed housing 11 is quickly unlocked through the linkage design of the pull rod 18, the fixing block 111 and the spring 19. The elastic reset function of the spring 19 ensures that the fixing block 111 automatically returns to its original position after the handle 112 is released, maintaining structural stability. When closing and fixing the upper cover body 12, align the upper cover body 12 with the docking groove 113 on the top of the housing 11 and press it down smoothly to close it. After releasing the handle 112, the spring 19 pushes the fixing block 111 to re-engage in the fixing groove 13, completing the firm fixation of the upper cover to the housing 11. The upper cover body 12 has two embedded cooling fans 17, which can actively draw hot air from inside the housing 11 during operation, enhance air circulation, and prevent the power amplifier module 31 from degrading or being damaged due to overheating.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
