Description

electronic device

technical field

The invention relates to an electronic device, especially an electronic device with good shock absorption performance.

Background technique

With the vigorous development of the electronic industry, the processing capacity of servers, which are high-performance products of computers, is also getting stronger and stronger. The composition of the server has many similarities with the computer, such as CPU (central processing unit), memory, hard disk, various buses, etc., but it can provide various shared services (network, database, file, print, etc.) As well as other high-performance applications, its high performance is mainly reflected in high-speed computing capabilities, long-term reliable operation, and powerful external data throughput capabilities. It is the center of the network and the core of informatization. Once the server fails, the economic loss will be unpredictable.

To maintain the uninterrupted work of the server, the cooling capacity inside the server is very important. For this reason, a common practice in the industry is to fix a fan module on the casing inside the server by means of screw fixing to cool the heating elements inside the server. However, when the fan rotates, vibration is usually generated, especially the higher the fan speed, the greater the vibration. These vibrations directly drive other components inside the server to vibrate through the casing, thereby affecting the performance of these components. At the same time, these vibrations will cause noise inside the server.

However, due to the limitation of the height of the internal space of the server, for example, the internal height of a 1U server is usually only 44 mm, and the internal space is only 41 mm after deducting the upper and lower thickness of the chassis (about 3 mm). The height of the fan module is 40 mm, so the design space to avoid vibration transmission is only 1 mm, that is, there is only 0.5 mm design space for the top and bottom. In such a narrow space, not only the cooperation between the fan module and other components must be considered, but also a suitable shock-absorbing structure should be designed between the fan module and the casing. However, under the condition that the damping space between the casing and the fan module is over-compressed, the damping effect of the damping structure is counterproductive. Therefore, how to damp the vibration of the fan module in the narrow space of the server has become an important problem to be solved in the industry.

In view of this, it is necessary to provide an electronic device with simple structure and excellent performance.

An electronic device includes a housing, a mounting frame fixed to the housing, and a fan module housed in the housing and embedded with the mounting frame, the housing includes a top plate and the A bottom plate opposite to the top plate, the fan module further includes two shock absorbers respectively fixed on opposite sides thereof and elastically abutted against the top plate and the bottom plate respectively, and each of the two shock absorbers has two The top plate and the bottom plate are respectively abutted against each other, and each shock absorber includes an abutment portion protruding from the outside of the fan module, and the abutment portion elastically abuts against the housing, and each shock absorber further includes An extension part extending from one side of the abutting member, the extension part is spaced apart from the casing and abuts against the fan of the fan module, the side of the extension part facing the fan is an inclined plane, and several intervals The second contact pin protrudes from the slope and abuts against the fan.

At this time, the blocking piece 5553 of the joint portion 555 abuts against the first side plate 533 of the fixing frame 53 . The extension part 553 is accommodated in the gap between the first side plate 533 and the barrel 512 of the fan 51 , and its inclined surface 5532 faces the barrel 512 , and the second contact foot 5534 on the inclined surface 5532 elastically abuts against the barrel 512 . A side of the connecting plate 5512 of the top 551 without the first contact pin 5514 is against the cylinder 512 of the fan 51 and a side edge of the first side plate 533 of the fixing frame 53 . The thickness of the connection plate 5512 is equal to the width difference between the first side plate 533 and the second side plate 535 on the corresponding side of the fixed frame 53, that is, the surface of the connection plate 5512 on the side where the first contact pin 5514 is provided is the same as the convex plate 516 corresponding to the fan 51 Parallel and coplanar, so that the first contact pin 5514 protrudes outside the fixing frame 53 and the fan 51 .

Please refer to FIGS. 1 to 3 at the same time. When the assembled fan module 50 is installed on the mounting frame 30, the fan module 50 is sandwiched between the first bracket 31 and the second bracket 33, and the fixing bracket 53 The two hooks 5317 at one end extend into the two corresponding openings 315 of the first bracket 31 to hook the baffle 312 , and the two hooks 5317 at the other end of the fixing frame 53 insert into the corresponding openings 336 of the second bracket 33 . At this time, the first contact feet 5514 of the shock absorbing member 55 located on the upper and lower opposite sides of the fixing frame 53 respectively abut against the top plate 11 and the bottom plate 13 of the casing 10 . At this time, the fan module 50 is completely fixed in the housing 10 and spaced apart from the second flange 14 .

In the present invention, since the fixing frame 53 of the fan module 50 and the fan 51 are not in direct contact with the casing 10, the vibration generated by the operation of the fan 51 is directly absorbed by the shock absorbers 55 fixed on the upper and lower opposite sides of the fixing frame 53. Therefore, the vibration transmitted to the housing 10 is less, so that the installation and other components in the housing 10 are not disturbed by vibration and maintain stable performance, and at the same time, the noise caused by the vibration of these components is avoided.
