In the case where prominent, following embodiments and its technical characteristic be can be combined with each other.Also, directional terminology used by full text, example
Such as "upper", "lower" are for preferably describing each embodiment, are not intended to limit the protection scope of the application.
Fig. 2 is the structural profile illustration of the radiating subassembly of one embodiment of the application.Referring to Fig. 2, the radiating subassembly
Including fixing seat 21, elastic component 22 and radiating piece 23.
Fixing seat 21 can be considered the shell of electronic equipment, such as lower cover or rear cover, for carrying the PCB etc. of electronic equipment
Internal structural element, and while bearing structure element, which can also arrange what driving structure element was run
Driving circuit, such as FPC (Flexible Printed Circuit, flexible circuit board), IC and relevant tracks.
Elastic component 22 is set in fixing seat 21 and needs thermal component 25 for carrying, which has scalable spy
Property, that is to say, that the elastic component 22 can extend along a length thereof direction stretching, extension and compression, need to radiate with what this was driven that it is carried
Component 25 upwardly or downwardly moves, and what is carried in other words to it needs the active force of the application of thermal component 25 upwardly or downwardly.
Radiating piece 23 is set to the top of the elastic component 22, specifically, installs in each structural detail of electronic equipment
After being fixed in fixing seat 21, radiating piece 23 is pressed in the upper surface for needing thermal component 25.Wherein, thermal component 25 is needed
Top should be higher than that before unassembled radiating piece 23 installation radiating piece 23 after, the part being higher by and the weight of radiating piece 23
And the oscillatory surge size of electronic equipment at runtime is related.In this, which contacts (specifically with thermal component 25 is needed
For face contact), passage of heat is formed between the two, and the heat for needing thermal component 25 to generate is ultimately conducted to by the passage of heat
In external environment.
Based on above-mentioned design, 22 pairs of elastic component need thermal component 25 to apply upward power, while 23 pairs of radiating piece need to radiate

To two sides or surrounding.Wherein, in order to ensure needing thermal component 25 from elastic component 22 by uniformly upward active force, the application
The distribution of these elastic components 22 can be set according to the position of centre of gravity of thermal component 25 is needed, for example, when needing thermal component 25
When center of gravity is located at the center of loading end locating for support plate 24, these elastic components 22 can be symmetrically distributed in the opposite of support plate 24
Two sides or surrounding；In another example the application can be at this when needing the center of gravity of thermal component 25 to be biased to certain side of support plate 24
A fairly large number of elastic component 22 is arranged in side.
In application scenarios, elastic component 22 can be spring, and in order to avoid spring 22 is when carrying needs thermal component 25
Limited post 211 can be arranged in left and right offset, the application in fixing seat 21, which is arranged in a one-to-one correspondence with spring 22,
Each limited post 211 is inserted in a corresponding spring 22, and the top of spring 22 and the lower surface of support plate 24 abut against.
Limited post 211 can be screw, and screw is passed through from the through-hole of support plate 24 and finally fixed with 21 phase of fixing seat.
It should be noted that the internal diameter for the through-hole that support plate 24 is opened up should be greater than the diameter of limited post 211, thus support plate 24 and it is carried on
Thereon need thermal component 25 that can move up and down under the telescopic action of elastomer 22.Certainly, the limited post 211 can also be with
It is not limited with the integrally formed structural member of fixing seat 21, the application this.
