Description

Technical Field

[0001] The utility model relates to the technical field of computers, in particular to a noise reduction structure. Background Art

It can perform numerical calculations, logical calculations, and has storage and memory functions. It is a modern intelligent electronic device that can run according to programs and automatically and quickly process massive amounts of data. With the continuous development of science and technology, the size of computers is getting smaller and smaller, and the use of various portable computers, such as notebook computers, is becoming more popular.

[0003] Prior art includes a utility model with publication number CN202694217U. The utility model relates to a portable computer, and more particularly to a portable computer with a pop-up camera. The portable computer comprises a computer body and a display unit rotatably connected to the computer body. A camera is arranged on the computer body. The camera can be hidden inside the computer body or exposed outside the computer body as required, and when it is exposed outside the computer body, the camera can rotate in a vertical plane. With the portable computer, a user can use the camera as required and adjust the shooting angle of the camera at the same time, thereby solving various problems affecting the shooting effect of the camera, such as low frame rate, poor sensitivity, insufficient light transmittance, etc., of the built-in camera on the existing portable computer.

[0004] The inventor found in his daily work that the existing portable computers mainly dissipate heat through cooling fans when in use, but the portable computers mainly use cooling holes on both sides for air intake and fan heat dissipation. Since the air intake and exhaust of the cooling holes are slow, the heat cannot be quickly discharged, and a large amount of heat accumulates on the inner wall, causing the cooling fan to rotate at a high speed to dissipate heat, resulting in relatively loud noise that affects use, which in turn leads to poor heat dissipation effect of the existing portable computers and the problem of noise generated by the high-speed operation of the cooling fan. Utility Model Content

Push plates are fixedly connected to the surfaces of the two positioning rods, and two hollow sleeves are fixedly connected to the surface of the mounting plate. The positioning rods are plugged into the inner walls of the hollow sleeves. Through the above-mentioned components, when the rotating plate drives the shielding net to reset, the positioning rods are inserted into the hollow sleeves through the push plates, thereby limiting the rotating plate.

[0008] Preferably, a return spring is provided on the surface of the positioning rod, and the two ends of the return spring are fixedly connected to the surfaces of the protrusion and the push plate respectively.

[0011] Preferably, a positioning spring is fixedly connected to one side of the plug block corresponding to the inner wall of the mounting plate, and there are four positioning springs. Through the above components, the positioning spring can be inserted into the slot on the inner wall of the mounting groove against the plug block to achieve installation positioning.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. In the utility model, by setting a heat dissipation device, when it is needed to be used, the push plate and the two positioning rods are pushed, the positioning spring is stressed, and after the positioning rod is moved out of the hollow sleeve, the torsion spring drives the rotating rod and the rotating plate to rotate, so that the rotating plate drives the shielding net to unfold, thereby expanding the heat dissipation area, and air quickly enters or exits the heat dissipation areas on both sides to dissipate heat. By setting a heat dissipation device, the overall heat dissipation effect of the equipment can be improved, and the existing portable computer is mainly cooled by the heat dissipation fan when in use. However, the portable computer mainly uses the heat dissipation holes on both sides for air intake and fan heat dissipation. Since the heat dissipation holes have slow air intake and air discharge, the heat cannot be quickly discharged, and a large amount of heat is accumulated on the inner wall, resulting in the heat dissipation fan rotating at a high speed to dissipate heat, causing a relatively large noise that affects the use.

[0024] Specifically, the heat dissipation device 4 includes a mounting plate 41. There are two mounting plates 41. The two mounting plates 41 are respectively arranged on both sides of the body 1. Both sides of the body 1 are provided with mounting grooves 42. The mounting plates 41 are plugged into the inner walls of the mounting grooves 42. The surface of the mounting plates 41 is provided with mounting components 49. The mounting plates 41 are installed in the mounting grooves 42 through the mounting components 49.

The surface of the rotating plate 43 is provided with multiple ventilation holes.

[0025] In this embodiment: the rotating plate 43 can be rotated to drive the shielding net 44 to unfold, thereby increasing the air intake and air outlet at the heat dissipation holes on both sides of the body 1, allowing the air on the inner wall to flow more smoothly, reducing heat accumulation and causing the problem of noise generated by high-speed rotation of the fan.

[0026] Specifically, a protrusion 46 is fixedly connected to the surface of the rotating plate 43, and two positioning rods 47 are slidably connected to the inner wall of the protrusion 46. A push plate 410 is fixedly connected to the surfaces of the two positioning rods 47. Two hollow sleeves 45 are fixedly connected to the surface of the mounting plate 41, and the positioning rods 47 are plugged into the inner wall of the hollow sleeves 45.

[0027] In this embodiment, after the rotating plate 43 drives the shielding net 44 to reset, the positioning rod 47 is inserted into the hollow sleeve 45 through the push plate 410 to limit the rotating plate 43.

[0028] Specifically, a return spring 48 is provided on the surface of the positioning rod 47, and the two ends of the return spring 48 are fixedly connected to the surface of the protrusion 46 and the push plate 410 respectively. The return spring 48 can control the push plate 410 and the positioning rod 47 to reset, while improving the stability of the positioning rod 47 in the hollow sleeve 45.

By setting up the heat dissipation device 4, the overall heat dissipation effect of the equipment can be improved, and the existing portable computer is mainly cooled by the cooling fan when in use. However, the portable computer mainly uses the cooling holes on both sides for air intake and fan cooling. Since the air intake and outlet of the cooling holes are slow, the heat cannot be quickly discharged, and a large amount of heat is accumulated on the inner wall, causing the cooling fan to rotate at a high speed to dissipate heat, resulting in a relatively large noise that affects the use.

[0035] By setting up the installation component 49, when disassembling or assembling, the push block 492 drives the plug block 493 to move, the positioning spring 494 is stressed, and the plug block 493 is moved out of the slot 491 on the inner wall of the installation groove 42, so that the installation plate 41 is removed as a whole, the shielding net 44 and the rotating plate 43 are cleaned, and the overall flexibility is improved.
